PN512 Full NFC Forum-compliant frontend Rev. 5.2 — 16 June 2016 Product data sheet 111352 COMPANY PUBLIC 1. General description PN512 is the most broadly adopted NFC frontend - powering more than 10 billion NFC transactions per year. It is a highly integrated NFC frontend for contactless communication at 13.56MHz. This NFC frontendutilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56MHz. The PN512 NFC frontend supports 4 different operating modes • Reader/Writer mode supporting ISO/IEC14443A/MIFARE and FeliCa scheme • Reader/Writer mode supporting ISO/IEC14443B • Card Operation mode supporting ISO/IEC14443A/MIFARE and FeliCa scheme • NFCIP-1 mode Enabled in Reader/Writer mode for ISO/IEC14443A/MIFARE, the PN512’s internal transmitter part is able to drive a reader/writer antenna designed to communicate with ISO/IEC14443A/ MIFARE cards and transponders without additional active circuitry. The receiver part provides a robust and efficient implementation of a demodulation and decoding circuitry for signals from ISO/IEC14443A/MIFARE compatible cards and transponders. The digital part handles the complete ISO/IEC14443A framing and error detection (Parity and CRC). Enabled in Reader/Writer mode for FeliCa, the PN512 NFC frontendsupports the FeliCa communication scheme. The receiver part provides a robust and efficient implementation of the demodulation and decoding circuitry for FeliCa coded signals. The digital part handles the FeliCa framing and error detection like CRC. The PN512 supports contactless communication using FeliCa Higher transfer speeds up to 424kbit/s in both directions. The PN512 supports all layers of the ISO/IEC14443B reader/writer communication scheme, given correct implementation of additional components, like oscillator, power supply, coil etc. and provided that standardized protocols, e.g. like ISO/IEC14443-4 and/or ISO/IEC14443B anticollision are correctly implemented. In Card Operation mode, the PN512 NFC frontend is able to answer to a reader/writer command either according to the FeliCa or ISO/IEC14443A/MIFARE card interface scheme. The PN512 generates the digital load modulated signals and in addition with an external circuit the answer can be sent back to the reader/writer. A complete card functionality is only possible in combination with a secure IC using the S2C interface.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend Additionally, the PN512 NFC frontendoffers the possibility to communicate directly to an NFCIP-1 device in the NFCIP-1 mode. The NFCIP-1 mode offers different communication mode and transfer speeds up to 424kbit/s according to the Ecma 340 and ISO/IEC18092 NFCIP-1 Standard. The digital part handles the complete NFCIP-1 framing and error detection. Various host controller interfaces are implemented: • 8-bit parallel interface1 • SPI interface • serial UART (similar to RS232 with voltage levels according pad voltage supply) • I2C interface. 1.1 Different available versions The PN512 is available in three versions: • PN5120A0HN1/C2 (HVQFN32), PN5120A0HN/C2 (HVQFN40) and PN5120A0ET/C2 (TFBGA64), hereafter named as version 2.0 • PN512AA0HN1/C2 (HVQFN32) and PN512AA0HN1/C2BI (HVQFN32 with Burn In), hereafter named as industrial version, fulfilling the automotive qualification stated in AEC-Q100 grade 3 from the Automotive Electronics Council, defining the critical stress test qualification for automotive integrated circuits (ICs). The customer recognizes that: – since the product was not originally designed for automotive use, it will not be possible to achieve the levels of quality and failure analysis that are normally associated with products explicitly designed for automotive use. – the product qualification conforms to AEC-Q100. – all product production locations are certified according to TS16949. • PN5120A0HN1/C1(HVQFN32) and PN5120A0HN/C1 (HVQFN40), hereafter named as version 1.0 The data sheet describes the functionality for the industrial version and version 2.0. The differences of the version 1.0 to the version 2.0 are summarized in Section20. The industrial version has only differences within the outlined characteristics and limitations. 1. 8-bit parallel Interface only available in HVQFN40 package.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 5. Block diagram The analog interface handles the modulation and demodulation of the analog signals according to the Card Receiving mode, Reader/Writer mode and NFCIP-1 mode communication scheme. The RF level detector detects the presence of an external RF-field delivered by the antenna to the RX pin. The Data mode detector detects a MIFARE, FeliCa or NFCIP-1 mode in order to prepare the internal receiver to demodulate signals, which are sent to the PN512. The communication (S2C) interface provides digital signals to support communication for transfer speeds above 424kbit/s and digital signals to communicate to a secure IC. The contactless UART manages the protocol requirements for the communication protocols in cooperation with the host. The FIFO buffer ensures fast and convenient data transfer to and from the host and the contactless UART and vice versa. Various host interfaces are implemented to meet different customer requirements. REGISTER BANK ANTENNA ANALOG CONTACTLESS INTERFACE UART FIFO SERIAL UART BUFFER SPI HOST I2C-BUS 001aaj627 Fig 1.

FeliCa framing and coding Preamble Sync Len n-Data CRC 00h 00h 00h 00h 00h 00h B2h 4Dh To enable the FeliCa communication a 6 byte preamble (00h, 00h, 00h, 00h, 00h, 00h) and 2 bytes Sync bytes (B2h, 4Dh) are sent to synchronize the receiver. The following Len byte indicates the length of the sent data bytes plus the LEN byte itself. The CRC calculation is done according to the FeliCa definitions with the MSB first. To transmit data on the RF interface, the host controller has to send the Len- and data- bytes to the PN512's FIFO-buffer. The preamble and the sync bytes are generated by the PN512 automatically and must not be written to the FIFO by the host controller. The PN512 performs internally the CRC calculation and adds the result to the data frame. Example for FeliCa CRC Calculation: Table 9.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 7.4 NFCIP-1 mode The NFCIP-1 communication differentiates between an active and a Passive Communication mode. • Active Communication mode means both the initiator and the target are using their own RF field to transmit data. • Passive Communication mode means that the target answers to an initiator command in a load modulation scheme. The initiator is active in terms of generating the RF field. • Initiator: generates RF field at 13.56MHz and starts the NFCIP-1 communication • Target: responds to initiator command either in a load modulation scheme in Passive Communication mode or using a self generated and self modulated RF field for Active Communication mode. In order to fully support the NFCIP-1 standard the PN512 supports the Active and Passive Communication mode at the transfer speeds 106kbit/s, 212kbit/s and 424kbit/s as defined in the NFCIP-1 standard.

However the datalink layer is according to the following policy: • Speed shall not be changed while continuum data exchange in a transaction. • Transaction includes initialization and anticollision methods and data exchange (in continuous way, meaning no interruption by another transaction). In order not to disturb current infrastructure based on 13.56MHz general rules to start NFCIP-1 communication are defined in the following way. 1. Per default NFCIP-1 device is in Target mode meaning its RF field is switched off. 2. The RF level detector is active. 3. Only if application requires the NFCIP-1 device shall switch to Initiator mode. 4. Initiator shall only switch on its RF field if no external RF field is detected by RF Level detector during a time of TIDT. 5. The initiator performs initialization according to the selected mode. 7.4.5 MIFARE Card operation mode Table 13.

Since they are used only for control means, there content is not influenced by internal state machines, e.g. the PageSelect-Register may be written and read by the -Controller. It will also be read by internal state machines, but never changed by them. dy dynamic These bits can be written and read by the -Controller. Nevertheless, they may also be written automatically by internal state machines, e.g. the Command-Register changes its value automatically after the execution of the actual command. r read only These registers hold bits, which value is determined by internal states only, e.g. the CRCReady bit can not be written from external but shows internal states. w write only Reading these registers returns always ZERO. RFU - These registers are reserved for future use. In case of a PN512 Version version 2.0 (VersionReg = 82h) a read access to these registers returns always the value “0”. Nevertheless this is not guaranteed for future chips versions where the value is undefined. In case of a write access, it is recommended to write always the value “0”.

In all other modes, the timer stops after the 4th bit if the bit RxMultiple the register RxModeReg is not set. If RxMultiple is set to logic1, the timer never stops. In this case the timer can be stopped by setting the bit TStopNow in register ControlReg to 1. Set to logic0 indicates, that the timer is not influenced by the protocol.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 9.2 Serial Peripheral Interface A serial peripheral interface (SPI compatible) is supported to enable high-speed communication to the host. The interface can handle data speeds up to 10 Mbit/s. When communicating with a host, the PN512 acts as a slave, receiving data from the external host for register settings, sending and receiving data relevant for RF interface communication. An interface compatible with SPI enables high-speed serial communication between the PN512 and a microcontroller. The implemented interface is in accordance with the SPI standard. The timing specification is given in Section25.1 on page117. PN512 SCK SCK MOSI MOSI MISO MISO NSS NSS 001aan220 Fig 13. SPI connection to host The PN512 acts as a slave during SPI communication. The SPI clock signal SCK must be generated by the master. Data communication from the master to the slave uses the MOSI line. The MISO line is used to send data from the PN512 to the master. Data bytes on both MOSI and MISO lines are sent with the MSB first. Data on both MOSI and MISO lines must be stable on the rising edge of the clock and can be changed on the falling edge. Data is provided by the PN512 on the falling clock edge and is stable during the rising clock edge. 9.2.1 SPI read data Reading data using SPI requires the byte order shown in Table143 to be used. It is possible to read out up to n-data bytes. The first byte sent defines both the mode and the address. Table 143. MOSI and MISO byte order Line Byte 0 Byte 1 Byte 2 To Byte n Byte n + 1 MOSI address 0 address 1 address 2 ... address n 00 MISO X[1] data 0 data 1 ... data n  1 data n [1] X = Do not care. Remark: The MSB must be sent first. 9.2.2 SPI write data To write data to the PN512 using SPI requires the byte order shown in Table144. It is possible to write up to n data bytes by only sending one address byte. PN512 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2016.

The default transfer speed is 9.6kBd. To change the transfer speed, the host controller must write a value for the new transfer speed to the SerialSpeedReg register. Bits BR_T0[2:0] and BR_T1[4:0] define the factors for setting the transfer speed in the SerialSpeedReg register. The BR_T0[2:0] and BR_T1[4:0] settings are described in Table10. Examples of different transfer speeds and the relevant register settings are given in Table11.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend The MSB of the first byte sets the mode used. To read data from the PN512, the MSB is set to logic1. To write data to the PN512 the MSB is set to logic0. Bit6 is reserved for future use, and bits5 to0 define the address; see Table151. Table 151.

The I2C-bus interface is implemented according to NXPSemiconductors’ I2C-bus interface specification, rev. 2.1, January 2000. The interface can only act in Slave mode. Therefore the PN512 does not implement clock generation or access arbitration. PULL-UP PULL-UP PN512 NETWORK NETWORK SDA SCL MICROCONTROLLER I2C CONFIGURATION EA WIRING ADR_[5:0] 001aan222 Fig 17. I2C-bus interface The PN512 can act either as a slave receiver or slave transmitter in Standard mode, Fast mode and High-speed mode. SDA is a bidirectional line connected to a positive supply voltage using a current source or a pull-up resistor. Both SDA and SCL lines are set HIGH when data is not transmitted. The PN512 has a 3-state output stage to perform the wired-AND function. Data on the I2C-bus can be transferred at data rates of up to 100kBd in Standard mode, up to 400kBd in Fast mode or up to 3.4Mbit/s in High-speed mode. If the I2C-bus interface is selected, spike suppression is activated on lines SCL and SDA as defined in the I2C-bus interface specification. See Table171 on page117 for timing requirements.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 9.4.1 Data validity Data on the SDA line must be stable during the HIGH clock period. The HIGH or LOW state of the data line must only change when the clock signal on SCL is LOW. SDA SCL data line change stable; of data data valid allowed mbc621 Fig 18. Bit transfer on the I2C-bus 9.4.2 START and STOP conditions To manage the data transfer on the I2C-bus, unique START(S) and STOP(P) conditions are defined. • A START condition is defined with a HIGH-to-LOW transition on the SDA line while SCL is HIGH. • A STOP condition is defined with a LOW-to-HIGH transition on the SDA line while SCL is HIGH. The I2C-bus master always generates the START and STOP conditions. The bus is busy after the START condition. The bus is free again a certain time after the STOP condition. The bus stays busy if a repeated START(Sr) is generated instead of a STOP condition. The START(S) and repeated START(Sr) conditions are functionally identical. Therefore, S is used as a generic term to represent both the START (S) and repeated START (Sr) conditions. SDA SDA SCL SCL S P START condition STOP condition mbc622 Fig 19. START and STOP conditions 9.4.3 Byte format Each byte must be followed by an acknowledge bit. Data is transferred with the MSB first; see Figure22. The number of transmitted bytes during one data transfer is unrestricted but must meet the read/write cycle format.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 9.4.4 Acknowledge An acknowledge must be sent at the end of one data byte. The acknowledge-related clock pulse is generated by the master. The transmitter of data, either master or slave, releases the SDA line (HIGH) during the acknowledge clock pulse. The receiver pulls down the SDA line during the acknowledge clock pulse so that it remains stable LOW during the HIGH period of this clock pulse. The master can then generate either a STOP(P) condition to stop the transfer or a repeated START(Sr) condition to start a new transfer. A master-receiver indicates the end of data to the slave-transmitter by not generating an acknowledge on the last byte that was clocked out by the slave. The slave-transmitter releases the data line to allow the master to generate a STOP (P) or repeated START (Sr) condition. data output by transmitter not acknowledge data output by receiver acknowledge SCL from 1 2 8 9 master S clock pulse for START acknowledgement condition mbc602 Fig 20.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 9.4.5 7-Bit addressing During the I2C-bus address procedure, the first byte after the START condition is used to determine which slave will be selected by the master. Several address numbers are reserved. During device configuration, the designer must ensure that collisions with these reserved addresses cannot occur. Check the I2C-bus specification for a complete list of reserved addresses. The I2C-bus address specification is dependent on the definition of pin EA. Immediately after releasing pin NRSTPD or after a power-on reset, the device defines the I2C-bus address according to pin EA. If pin EA is set LOW, the upper 4bits of the device bus address are reserved by NXPSemiconductors and set to 0101b for all PN512 devices. The remaining 3bits (ADR_0, ADR_1, ADR_2) of the slave address can be freely configured by the customer to prevent collisions with other I2C-bus devices. If pin EA is set HIGH, ADR_0 to ADR_5 can be completely specified at the external pins according to Table141 on page69. ADR_6 is always set to logic0. In both modes, the external address coding is latched immediately after releasing the reset condition. Further changes at the used pins are not taken into consideration. Depending on the external wiring, the I2C-bus address pins can be used for test signal outputs. MSB LSB bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0 R/W slave address 001aak591 Fig 22. First byte following the START procedure 9.4.6 Register write access To write data from the host controller using the I2C-bus to a specific register in the PN512 the following frame format must be used. • The first byte of a frame indicates the device address according to the I2C-bus rules. • The second byte indicates the register address followed by up to n-data bytes. In one frame all data bytes are written to the same register address. This enables fast FIFO buffer access. The Read/Write (R/W) bit is set to logic0.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 9.4.7 Register read access To read out data from a specific register address in the PN512, the host controller must use the following procedure: • Firstly, a write access to the specific register address must be performed as indicated in the frame that follows • The first byte of a frame indicates the device address according to the I2C-bus rules • The second byte indicates the register address. No data bytes are added • The Read/Write bit is0 After the write access, read access can start. The host sends the device address of the PN512. In response, the PN512 sends the content of the read access register. In one frame all data bytes can be read from the same register address. This enables fast FIFO buffer access or register polling.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 9.4.8 High-speed mode In High-speed mode (HSmode), the device can transfer information at data rates of up to 3.4Mbit/s, while remaining fully downward-compatible with Fast or Standard mode (F/Smode) for bidirectional communication in a mixed-speed bus system. 9.4.9 High-speed transfer To achieve data rates of up to 3.4Mbit/s the following improvements have been made to I2C-bus operation. • The inputs of the device in HSmode incorporate spike suppression, a Schmitttrigger on the SDA and SCL inputs and different timing constants when compared to F/Smode • The output buffers of the device in HSmode incorporate slope control of the falling edges of the SDA and SCL signals with different fall times compared to F/Smode 9.4.10 Serial data transfer format in HS mode The HSmode serial data transfer format meets the Standard mode I2C-bus specification. HSmode can only start after all of the following conditions (all of which are in F/Smode): 1. START condition (S) 2. 8-bit master code (00001XXXb) 3. Not-acknowledge bit (A) When HSmode starts, the active master sends a repeated START condition (Sr) followed by a 7-bit slave address with a R/W bit address and receives an acknowledge bit (A) from the selected PN512. Data transfer continues in HS mode after the next repeated START (Sr), only switching back to F/S mode after a STOP condition (P). To reduce the overhead of the master code, a master links a number of HS mode transfers, separated by repeated START conditions (Sr).

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 9.4.11 Switching between F/S mode and HS mode After reset and initialization, the PN512 is in Fast mode (which is in effect F/Smode as Fast mode is downward-compatible with Standard mode). The connected PN512 recognizes the “S 00001XXX A” sequence and switches its internal circuitry from the Fast mode setting to the HSmode setting. The following actions are taken: 1. Adapt the SDA and SCL input filters according to the spike suppression requirement in HSmode. 2. Adapt the slope control of the SDA output stages. It is possible for system configurations that do not have other I2C-bus devices involved in the communication to switch to HS mode permanently. This is implemented by setting Status2Reg register’s I2CForceHS bit to logic1. In permanent HS mode, the master code is not required to be sent. This is not defined in the specification and must only be used when no other devices are connected on the bus. In addition, spikes on the I2C-bus lines must be avoided because of the reduced spike suppression. 9.4.12 PN512 at lower speed modes PN512 is fully downward-compatible and can be connected to an F/Smode I2C-bus system. The device stays in F/Smode and communicates at F/Smode speeds because a master code is not transmitted in this configuration. 10. 8-bit parallel interface The PN512 supports two different types of 8-bit parallel interfaces, Intel and Motorola compatible modes. 10.1 Overview of supported host controller interfaces The PN512 supports direct interfacing to various -Controllers.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 11. Analog interface and contactless UART 11.1 General The integrated contactless UART supports the external host online with framing and error checking of the protocol requirements up to 848kBd. An external circuit can be connected to the communication interface pins MFIN and MFOUT to modulate and demodulate the data. The contactless UART handles the protocol requirements for the communication protocols in cooperation with the host. Protocol handling generates bit and byte-oriented framing. In addition, it handles error detection such as parity and CRC, based on the various supported contactless communication protocols. Remark: The size and tuning of the antenna and the power supply voltage have an important impact on the achievable operating distance. 11.2 TX driver The signal on pins TX1 and TX2 is the 13.56MHz energy carrier modulated by an envelope signal. It can be used to drive an antenna directly using a few passive components for matching and filtering; see Section14 on page96. The signal on pins TX1 and TX2 can be configured using the TxControlReg register; see Section8.2.2.5 on page40. The modulation index can be set by adjusting the impedance of the drivers. The impedance of the p-driver can be configured using registers CWGsPReg and ModGsPReg. The impedance of the n-driver can be configured using the GsNReg register. The modulation index also depends on the antenna design and tuning. The TxModeReg and TxSelReg registers control the data rate and framing during transmission and the antenna driver setting to support the different requirements at the different modes and transfer speeds.

Remark: If only one driver is switched on, the values for CWGsPReg, ModGsPReg and GsNReg registers are used for both drivers. 11.3 RF level detector The RF level detector is integrated to fulfill NFCIP1 protocol requirements (e.g. RF collision avoidance). Furthermore the RF level detector can be used to wake up the PN512 and to generate an interrupt.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend The sensitivity of the RF level detector is adjustable in a 4-bit range using the bits RFLevel in register RFCfgReg. The sensitivity itself depends on the antenna configuration and tuning. Possible sensitivity levels at the RX pin are listed in the Table154. Table 155. Setting of the bits RFlevel in register RFCfgReg (RFLevel amplifier deactivated) V~Rx [Vpp] RFLevel ~2 1111 ~1.4 1110 ~0.99 1101 ~0.69 1100 ~0.49 1011 ~0.35 1010 ~0.24 1001 ~0.17 1000 ~0.12 0111 ~0.083 0110 ~0.058 0101 ~0.041 0100 ~0.029 0011 ~0.020 0010 ~0.014 0001 ~0.010 0000 To increase the sensitivity of the RF level detector an amplifier can be activated by setting the bit RFLevelAmp in register RFCfgReg to1. Remark: During soft Power-down mode the RF level detector amplifier is automatically switched off to ensure that the power consumption is less than 10Aat3V. Remark: With typical antennas lower sensitivity levels can provoke misleading results because of intrinsic noise in the environment. Note: It is recommended to use the bit RFLevelAmp only with higher RF level settings. 11.4 Data mode detector The Data mode detector gives the possibility to detect received signals according to the ISO/IEC14443A/MIFARE, FeliCa or NFCIP-1 schemes at the standard transfer speeds for 106kbit, 212kbit and 424kbit in order to prepare the internal receiver in a fast and convenient way for further data processing. The Data mode detector can only be activated by the AutoColl command. The mode detector resets, when no external RF field is detected by the RF level detector. The Data mode detector could be switched off during the AutoColl command by setting bit ModeDetOff in register ModeReg to1.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 11.5 Serial data switch Two main blocks are implemented in the PN512. The digital block comprises the state machines, encoder/decoder logic. The analog block comprises the modulator and antenna drivers, the receiver and amplifiers. The interface between these two blocks can be configured in the way, that the interfacing signals may be routed to the pins SIGIN and SIGOUT. SIGIN is capable of processing digital NFC signals on transfer speeds above 424kbit. The SIGOUT pin can provide a digital signal that can be used with an additional external circuit to generate transfer speeds above 424kbit (including 106, 212 and 424kbit). Furthermore SIGOUT and SIGIN can be used to enable the S2C interface in the card SAM mode to emulate a card functionality with the PN512 and a secure IC. A secure IC can be the SmartMX smart card controller IC. This topology allows the analog block of the PN512 to be connected to the digital block of another device.

The interfacing signals can be routed to the pins SIGIN and SIGOUT. SIGIN can receive either a digital FeliCa or digitized ISO/IEC14443A signal sent by the secure IC.

Communication flows using the S2C interface Configured in the Secure Access Mode the host controller can directly communicate to the Secure IC via SIGIN/SIGOUT. In this mode the PN512 generates the RF clock and performs the communication on the SIGOUT line. To enable the Secure Access module mode the clock has to be derived by the internal oscillator of the PN512, see bits SAMClockSel in register TestSel1Reg. Configured in Contactless Card mode the secure IC can act as contactless smart card IC via the PN512. In this mode the signal on the SIGOUT line is provided by the external RF field of the external reader/writer. To enable the Contactless Card mode the clock derived by the external RF field has to be used.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 11.6.1 Signal shape for Felica S2C interface support The FeliCa secure IC is connected to the PN512 via the pins SIGOUT and SIGIN. The signal at SIGOUT contains the information of the 13.56MHz clock and the digitized demodulated signal. The clock and the demodulated signal is combined by using the logical function exclusive or. To ensure that this signal is free of spikes, the demodulated signal is digitally filtered first. The time delay for that digital filtering is in the range of one bit length. The demodulated signal changes only at a positive edge of the clock. The register TxSelReg controls the setting at SIGOUT. clock signal on SIGIN signal on antenna 001aan227 Fig 31. Signal shape for SIGOUT in FeliCa card SAM mode The answer of the FeliCa SAM is transferred from SIGIN directly to the antenna driver. The modulation is done according to the register settings of the antenna drivers. The clock is switched to AUX1 or AUX2 (see AnalogSelAux). Note: A HIGH signal on AUX1 and AUX2 has the same level as AVDD. A HIGH signal at SIGOUT has the same level as SVDD. Alternatively it is possible to use pin D0 as clock output if a serial interface is used. The HIGH level at D0 is the same as PVDD. clock demodulated signal signal on SIGOUT 001aan228 Fig 32.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 11.7 Hardware support for FeliCa and NFC polling 11.7.1 Polling sequence functionality for initiator 1. Timer: The PN512 has a timer, which can be programmed in a way that it generates an interrupt at the end of each timeslot, or if required an interrupt is generated at the end of the last timeslot. 2. The receiver can be configured in a way to receive continuously. In this mode it can receive any number of packets. The receiver is ready to receive the next packet directly after the last packet has been received. This mode is active by setting the bit RxMultiple in register RxModeReg to 1 and has to be stopped by software. 3. The internal UART adds one byte to the end of every received packet, before it is transferred into the FIFO-buffer. This byte indicates if the received byte packet is correct (see register ErrReg). The first byte of each packet contains the length byte of the packet. 4. The length of one packet is 18 or 20bytes (+1byte Error-Info). The FIFO has a length of 64bytes. This means three packets can be stored in the FIFO at the same time. If more than three packets are expected, the host controller has to empty the FIFO, before the FIFO is filled completely. In case of a FIFO-overflow data is lost (See bit BufferOvfl in register ErrorReg). 11.7.2 Polling sequence functionality for target 1. The host controller has to configure the PN512 with the correct polling response parameters for the polling command. 2. To activate the automatic polling in Target mode, the AutoColl Command has to be activated. 3. The PN512 receives the polling command send out by an initiator and answers with the polling response. The timeslot is selected automatically (The timeslot itself is randomly generated, but in the range 0 to TSN, which is defined by the Polling command). The PN512 compares the system code, stored in byte 17 and 18 of the Config Command with the system code received by the polling command of an initiator. If the system code is equal, the PN512 answers according to the configured polling response. The system code FF (hex) acts as a wildcard for the system code bytes, i.e. a target of a system code 1234(hex) answers to the polling command with one of the following system codes 1234(hex), 12FF(hex), FF34(hex) or FFFF(hex). If the system code does not match no answer is sent back by the PN512. If a valid command is received by the PN512, which is not a Polling command, no answer is sent back and the command AutoColl is stopped. The received packet is stored in the FIFO.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 11.7.3 Additional hardware support for FeliCa and NFC Additionally to the polling sequence support for the Felica mode, the PN512 supports the check of the Len-byte. The received Len-byte in accordance to the registers FelNFC1Reg and FelNFC2Reg: DataLenMin in register FelNFC1Reg defines the minimum length of the accepted packet length. This register is six bit long. Each bit represents a length of four bytes. DataLenMax in register FelNFC2Reg defines the maximum length of the accepted package. This register is six bit long. Each bit represents a length of four bytes. If set to logic1 this limit is ignored. If the length is not in the supposed range, the packet is not transferred to the FIFO and receiving is kept active. Example 1: • DataLenMin=4 – The length shall be greater or equal16. • DataLenMax=5 – The length shall be smaller than 20. Valid area: 16, 17, 18, 19 Example 2: • DataLenMin=9 – The length shall be greater or equal36. • DataLenMax=0 – The length shall be smaller than 256. Valid area: 36to255 11.7.4 CRC coprocessor The following CRC coprocessor parameters can be configured: • The CRC preset value can be either 0000h, 6363h, A671h or FFFFh depending on the ModeReg register’s CRCPreset[1:0] bits setting • The CRC polynomial for the 16-bit CRC is fixed to x16+x12+x5+1 • The CRCResultReg register indicates the result of the CRC calculation. This register is split into two 8-bit registers representing the higher and lower bytes. • The ModeReg register’s MSBFirst bit indicates that data will be loaded with the MSB first. Table 156. CRC coprocessor parameters Parameter Value CRC register length 16-bit CRC CRC algorithm algorithm according to ISO/IEC14443A and ITU-T CRC preset value 0000h, 6363h, A671h or FFFFh depending on the setting of the ModeReg register’s CRCPreset[1:0] bits PN512 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2016.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 12. FIFO buffer An 864 bit FIFO buffer is used in the PN512. It buffers the input and output data stream between the host and the PN512’s internal state machine. This makes it possible to manage data streams up to 64bytes long without the need to take timing constraints into account. 12.1 Accessing the FIFO buffer The FIFO buffer input and output data bus is connected to the FIFODataReg register. Writing to this register stores one byte in the FIFO buffer and increments the internal FIFO buffer write pointer. Reading from this register shows the FIFO buffer contents stored in the FIFO buffer read pointer and decrements the FIFO buffer read pointer. The distance between the write and read pointer can be obtained by reading the FIFOLevelReg register. When the microcontroller starts a command, the PN512 can, while the command is in progress, access the FIFO buffer according to that command. Only one FIFO buffer has been implemented which can be used for input and output. The microcontroller must ensure that there are not any unintentional FIFO buffer accesses. 12.2 Controlling the FIFO buffer The FIFO buffer pointers can be reset by setting FIFOLevelReg register’s FlushBuffer bit to logic1. Consequently, the FIFOLevel[6:0] bits are all set to logic0 and the ErrorReg register’s BufferOvfl bit is cleared. The bytes stored in the FIFO buffer are no longer accessible allowing the FIFO buffer to be filled with another 64 bytes. 12.3 FIFO buffer status information The host can get the following FIFO buffer status information: • Number of bytes stored in the FIFO buffer: FIFOLevelReg register’s FIFOLevel[6:0] • FIFO buffer almost full warning: Status1Reg register’s HiAlert bit • FIFO buffer almost empty warning: Status1Reg register’s LoAlert bit • FIFO buffer overflow warning: ErrorReg register’s BufferOvfl bit. The BufferOvfl bit can only be cleared by setting the FIFOLevelReg register’s FlushBuffer bit. The PN512 can generate an interrupt signal when: • ComIEnReg register’s LoAlertIEn bit is set to logic1. It activates pin IRQ when Status1Reg register’s LoAlert bit changes to logic1. • ComIEnReg register’s HiAlertIEn bit is set to logic1. It activates pin IRQ when Status1Reg register’s HiAlert bit changes to logic1. If the maximum number of WaterLevel bytes (as set in the WaterLevelReg register) or less are stored in the FIFO buffer, the HiAlert bit is set to logic1. It is generated according to Equation3: HiAlert = 64–FIFOLengthWaterLevel (3) PN512 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2016.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend If the number of WaterLevel bytes (as set in the WaterLevelReg register) or less are stored in the FIFO buffer, the LoAlert bit is set to logic1. It is generated according to Equation4: LoAlert = FIFOLengthWaterLevel (4) 13. Interrupt request system The PN512 indicates certain events by setting the Status1Reg register’s IRq bit and, if activated, by pin IRQ. The signal on pin IRQ can be used to interrupt the host using its interrupt handling capabilities. This allows the implementation of efficient host software. 13.1 Interrupt sources overview Table157 shows the available interrupt bits, the corresponding source and the condition for its activation. The ComIrqReg register’s TimerIRq interrupt bit indicates an interrupt set by the timer unit which is set when the timer decrements from 1 to 0. The ComIrqReg register’s TxIRq bit indicates that the transmitter has finished. If the state changes from sending data to transmitting the end of the frame pattern, the transmitter unit automatically sets the interrupt bit. The CRC coprocessor sets the DivIrqReg register’s CRCIRq bit after processing all the FIFO buffer data which is indicated by CRCReadybit=1. The ComIrqReg register’s RxIRq bit indicates an interrupt when the end of the received data is detected. The ComIrqReg register’s IdleIRq bit is set if a command finishes and the Command[3:0] value in the CommandReg register changes to idle (see Table158 on page101). The ComIrqReg register’s HiAlertIRq bit is set to logic1 when the Status1Reg register’s HiAlert bit is set to logic1 which means that the FIFO buffer has reached the level indicated by the WaterLevel[5:0] bits. The ComIrqReg register’s LoAlertIRq bit is set to logic1 when the Status1Reg register’s LoAlert bit is set to logic 1 which means that the FIFO buffer has reached the level indicated by the WaterLevel[5:0] bits. The ComIrqReg register’s ErrIRq bit indicates an error detected by the contactless UART during send or receive. This is indicated when any bit is set to logic1 in register ErrorReg. Table 157.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 14. Timer unit A timer unit is implemented in the PN512. The external host controller may use this timer to manage timing relevant tasks. The timer unit may be used in one of the following configurations: • Time-out counter • Watch-dog counter • Stop watch • Programmable one-shot • Periodical trigger The timer unit can be used to measure the time interval between two events or to indicate that a specific event occurred after a specific time. The timer can be triggered by events which will be explained in the following, but the timer itself does not influence any internal event (e.g. A time-out during data reception does not influence the reception process automatically). Furthermore, several timer related bits are set and these bits can be used to generate an interrupt. Timer The timer has an input clock of 13.56MHz (derived from the 27.12MHz quartz). The timer consists of two stages: 1prescaler and 1counter. The prescaler is a 12-bit counter. The reload value for TPrescaler can be defined between 0 and 4095 in register TModeReg and TPrescalerReg. The reload value for the counter is defined by 16bits in a range of 0 to 65535 in the register TReloadReg. The current value of the timer is indicated by the register TCounterValReg. If the counter reaches 0 an interrupt will be generated automatically indicated by setting the TimerIRq bit in the register CommonIRqReg. If enabled, this event can be indicated on the IRQ line. The bit TimerIRq can be set and reset by the host controller. Depending on the configuration the timer will stop at 0 or restart with the value from register TReloadReg. The status of the timer is indicated by bit TRunning in register Status1Reg. The timer can be manually started by TStartNow in register ControlReg or manually stopped by TStopNow in register ControlReg. Furthermore the timer can be activated automatically by setting the bit TAuto in the register TModeReg to fulfill dedicated protocol requirements automatically. The time delay of a timer stage is the reload value +1. The definition of total time is: t = ((TPrescaler*2+1)*TReload+1)/13.56MHz or if TPrescaleEven bit is set: t = ((TPrescaler*2+2)*TReload+1)/13.56MHz Maximum time: TPrescaler=4095,TReloadVal=65535 => (2*4095 +2)*65536/13.56MHz = 39.59s Example: PN512 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2016.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend To indicate 25us it is required to count 339clock cycles. This means the value for TPrescaler has to be set to TPrescaler=169.The timer has now an input clock of 25us. The timer can count up to 65535 timeslots of each 25s.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 15. Power reduction modes 15.1 Hard power-down Hard power-down is enabled when pin NRSTPD is LOW. This turns off all internal current sinks including the oscillator. All digital input buffers are separated from the input pins and clamped internally (except pin NRSTPD). The output pins are frozen at either a HIGH or LOW level. 15.2 Soft power-down mode Soft Power-down mode is entered immediately after the CommandReg register’s PowerDown bit is set to logic1. All internal current sinks are switched off, including the oscillator buffer. However, the digital input buffers are not separated from the input pins and keep their functionality. The digital output pins do not change their state. During soft power-down, all register values, the FIFO buffer content and the configuration keep their current contents. After setting the PowerDown bit to logic0, it takes 1024 clocks until the Soft power-down mode is exited indicated by the PowerDown bit. Setting it to logic0 does not immediately clear it. It is cleared automatically by the PN512 when Soft power-down mode is exited. Remark: If the internal oscillator is used, you must take into account that it is supplied by pin AVDD and it will take a certain time (t ) until the oscillator is stable and the clock osc cycles can be detected by the internal logic. It is recommended for the serial UART, to first send the value 55h to the PN512. The oscillator must be stable for further access to the registers. To ensure this, perform a read access to address 0 until the PN512 answers to the last read command with the register content of address 0. This indicates that the PN512 is ready. 15.3 Transmitter power-down mode The Transmitter Power-down mode switches off the internal antenna drivers thereby, turning off the RF field. Transmitter power-down mode is entered by setting either the TxControlReg register’s Tx1RFEn bit or Tx2RFEn bit to logic0.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend 16. Oscillator circuitry PN512 OSCOUT OSCIN 27.12 MHz 001aan231 Fig 35. Quartz crystal connection The clock applied to the PN512 provides a time basis for the synchronous system’s encoder and decoder. The stability of the clock frequency, therefore, is an important factor for correct operation. To obtain optimum performance, clock jitter must be reduced as much as possible. This is best achieved using the internal oscillator buffer with the recommended circuitry. If an external clock source is used, the clock signal must be applied to pin OSCIN. In this case, special care must be taken with the clock duty cycle and clock jitter and the clock quality must be verified. 17. Reset and oscillator start-up time 17.1 Reset timing requirements The reset signal is filtered by a hysteresis circuit and a spike filter before it enters the digital circuit. The spike filter rejects signals shorter than 10ns. In order to perform a reset, the signal must be LOW for at least 100ns. 17.2 Oscillator start-up time If the PN512 has been set to a Power-down mode or is powered by a V supply, the DDX start-up time for the PN512 depends on the oscillator used and is shown in Figure36. The time (t ) is the start-up time of the crystal oscillator circuit. The crystal oscillator startup start-up time is defined by the crystal. The time (t ) is the internal delay time of the PN512 when the clock signal is stable before d the PN512 can be addressed. The delay time is calculated by: 1024 t = -------------- = 37.74 s (5) d 27 s The time (t ) is the sum of t and t . osc d startup PN512 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2016.

PN512 command set The PN512 operation is determined by a state machine capable of performing a set of commands. A command is executed by writing a command code (see Table158) to the CommandReg register. Arguments and/or data necessary to process a command are exchanged via the FIFO buffer. 18.1 General description The PN512 operation is determined by a state machine capable of performing a set of commands. A command is executed by writing a command code (see Table158) to the CommandReg register. Arguments and/or data necessary to process a command are exchanged via the FIFO buffer. 18.2 General behavior • Each command that needs a data bit stream (or data byte stream) as an input immediately processes any data in the FIFO buffer. An exception to this rule is the Transceive command. Using this command, transmission is started with the BitFramingReg register’s StartSend bit. • Each command that needs a certain number of arguments, starts processing only when it has received the correct number of arguments from the FIFO buffer. • The FIFO buffer is not automatically cleared when commands start. This makes it possible to write command arguments and/or the data bytes to the FIFO buffer and then start the command. • Each command can be interrupted by the host writing a new command code to the CommandReg register, for example, the Idle command.

The Idle command also terminates itself. 18.3.1.2 Config command To use the automatic MIFARE Anticollision, FeliCa Polling and NFCID3 the data used for these transactions has to be stored internally. All the following data have to be written to the FIFO in this order: SENS_RES (2 bytes); in order byte 0, byte 1 NFCID1 (3 Bytes); in order byte 0, byte 1, byte 2; the first NFCID1 byte is fixed to 08h and the check byte is calculated automatically. SEL_RES (1 Byte) polling response (2 bytes (shall be 01h, FEh) + 6 bytes NFCID2 + 8 bytes Pad + 2 bytes system code) NFCID3 (1 byte) In total 25 bytes are transferred into an internal buffer. The complete NFCID3 is 10 bytes long and consists of the 3 NFCID1 bytes, the 6 NFCID2 bytes and the one NFCID3 byte which are listed above. To read out this configuration the command Config with an empty FIFO-buffer has to be started. In this case the 25 bytes are transferred from the internal buffer to the FIFO.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend The PN512 has to be configured after each power up, before using the automatic Anticollision/Polling function (AutoColl command). During a hard power down (reset pin) this configuration remains unchanged. This command terminates automatically when finished and the active command is idle. 18.3.1.3 Generate RandomID This command generates a 10-byte random number which is initially stored in the internal buffer. This then overwrites the 10bytes in the internal 25-byte buffer. This command automatically terminates when finished and the PN512 returns to Idle mode. 18.3.1.4 CalcCRC The FIFO buffer content is transferred to the CRC coprocessor and the CRC calculation is started. The calculation result is stored in the CRCResultReg register. The CRC calculation is not limited to a dedicated number of bytes. The calculation is not stopped when the FIFO buffer is empty during the data stream. The next byte written to the FIFO buffer is added to the calculation. The CRC preset value is controlled by the ModeReg register’s CRCPreset[1:0] bits. The value is loaded in to the CRC coprocessor when the command starts. This command must be terminated by writing a command to the CommandReg register, such as, the Idle command. If the AutoTestReg register’s SelfTest[3:0] bits are set correctly, the PN512 enters Self Test mode. Starting the CalcCRC command initiates a digital self test. The result of the self test is written to the FIFO buffer. 18.3.1.5 Transmit The FIFO buffer content is immediately transmitted after starting this command. Before transmitting the FIFO buffer content, all relevant registers must be set for data transmission. This command automatically terminates when the FIFO buffer is empty. It can be terminated by another command written to the CommandReg register. 18.3.1.6 NoCmdChange This command does not influence any running command in the CommandReg register. It can be used to manipulate any bit except the CommandReg register Command[3:0] bits, for example, the RcvOff bit or the PowerDown bit. 18.3.1.7 Receive The PN512 activates the receiver path and waits for a data stream to be received. The correct settings must be chosen before starting this command. This command automatically terminates when the data stream ends. This is indicated either by the end of frame pattern or by the length byte depending on the selected frame type and speed. Remark: If the RxModeReg register’s RxMultiple bit is set to logic1, the Receive command will not automatically terminate. It must be terminated by starting another command in the CommandReg register. PN512 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2016.

The first action is transmit and after transmission the command is changed to receive a data stream. Each transmit process must be started by setting the BitFramingReg register’s StartSend bit tologic1. This command must be cleared by writing any command to the CommandReg register. Remark: If the RxModeReg register’s RxMultiple bit is set to logic1, the Transceive command never leaves the receive state because this state cannot be cancelled automatically. 18.3.1.9 AutoColl This command automatically handles the MIFARE activation and the FeliCa polling in the Card Operation mode. The bit Initiator in the register ControlReg has to be set to logic 0 for correct operation. During this command also the mode detector is active if not deactivated by setting the bit ModeDetOff in the ModeReg register. After the mode detector detects a mode, all the mode dependent registers are set according to the received data. In case of no external RF field the command resets the internal state machine and returns to the initial state but it will not be terminated. When the command terminates the transceive command gets active. During protocol processing the IRQ bits are not supported. Only the last received frame will serve the IRQ’s. The treatment of the TxCRCEn and RxCRCEn bits is different to the protocol. During ISO/IEC 14443A activation the enable bits are defined by the command AutoColl. The changes cannot be observed at the register TXModeReg and RXModeReg. After the Transceive command is active, the value of the register bit is relevant. The FIFO will also receive the two CRC check bytes of the last command even if they already checked and correct, if the state machine (Anticollision and Select routine) has to not been executed and 106 kbit is detected. During Felica activation the register bit is always relevant and is not overruled by the command settings. This command can be cleared by software by writing any other command to the CommandReg register, e.g. the idle command. Writing the same content again to the CommandReg register resets the state machine. PN512 All information provided in this document is subject to legal disclaimers. © NXP Semiconductors N.V. 2016.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend MIFARE (Card Operation mode): The MIFARE anticollision is finished and the command has automatically changed to transceive. The FIFO contains the first command after the Select. The bit TargetActivated in the Status2Reg register is set to logic 1. Felica (Card Operation mode): The FeliCa polling command is finished and the command has automatically changed to transceive. The FIFO contains the first command followed after the Poling by the FeliCa protocol. The bit TargetActivated in the Status2Reg register is set to logic 1. 18.3.1.10 MFAuthent This command manages MIFARE authentication to enable a secure communication to any MIFARE Mini, MIFARE 1K and MIFARE 4K card. The following data is written to the FIFO buffer before the command can be activated: • Authentication command code (60h, 61h) • Block address • Sector key byte0 • Sector key byte1 • Sector key byte2 • Sector key byte3 • Sector key byte4 • Sector key byte5 • Card serial number byte0 • Card serial number byte1 • Card serial number byte2 • Card serial number byte3 In total 12bytes are written to the FIFO. Remark: When the MFAuthent command is active all access to the FIFO buffer is blocked. However, if there is access to the FIFO buffer, the ErrorReg register’s WrErr bit is set. This command automatically terminates when the MIFARE card is authenticated and the Status2Reg register’s MFCrypto1On bit is set to logic1. This command does not terminate automatically if the card does not answer, so the timer must be initialized to automatic mode. In this case, in addition to the IdleIRq bit, the TimerIRq bit can be used as the termination criteria. During authentication processing, the RxIRq bit and TxIRq bit are blocked. The Crypto1On bit is only valid after termination of the MFAuthent command, either after processing the protocol or writing Idle to the CommandReg register. If an error occurs during authentication, the ErrorReg register’s ProtocolErr bit is set to logic1 and the Status2Reg register’s Crypto1On bit is set to logic0.

Errata sheet This data sheet is describing the functionality for version 2.0 and the industrial version. This chapter lists all differences from version 1.0 to version 2.0: The value of the version in Section8.2.4.8 is set to80h. The behaviour ‘RFU’ for the register is undefined. The answer to the Selftest (see Section19.1) for version 1.0 (VersionReg equal to 80h): 00h, AAh, E3h, 29h, 0Ch, 10h, 29zhh, 6Bh, 76h, 8Dh, AFh, 4Bh, A2h, DAh, 76h, 99h C7h, 5Eh, 24h, 69h, D2h, BAh, FAh, BCh 3Eh, DAh, 96h, B5h, F5h, 94h, B0h, 3Ah 4Eh, C3h, 9Dh, 94h, 76h, 4Ch, EAh, 5Eh 38h, 10h, 8Fh, 2Dh, 21h, 4Bh, 52h, BFh 4Eh, C3h, 9Dh, 94h, 76h, 4Ch, EAh, 5Eh 38h, 10h, 8Fh, 2Dh, 21h, 4Bh, 52h, BFh FBh, F4h, 19h, 94h, 82h, 5Ah, 72h, 9Dh BAh, 0Dh, 1Fh, 17h, 56h, 22h, B9h, 08h Only the default setting for the prescaler (see Section 14 “Timer unit” on page 96): t = ((TPreScaler*2+1)*TReload+1)/13,56 MHz is supported. As such only the formula f = Timer 13,56 MHz/(2*PreScaler+1) is applicable for the TPrescalerHigh in Table 100 “Description of TModeReg bits” on page 57 and TPrescalerLo in Table 101 “TPrescalerReg register (address 2Bh); reset value: 00h, 00000000b” on page 58. As there is no option for the prescaler available, also the TPrescalEven is not available Section8.2.2.10 on page45. This bit is set to ‘RFU’.

PN512 NXP Semiconductors Full NFC Forum-compliant frontend Especially when using time slot protocols, it is needed that the error flag is copied into the status information of the frame. When using the RxMultiple feature (see Section8.2.2.4 on page39) within version 1.0 the protocol error flag is not included in the status information for the frame. In addition the CRCOk is copied instead of the CRCErr. This can be a problem in frames without length information e.g. ISO/IEC 14443-B. The version 1.0 does not accept a Type B EOF if there is no 1 bit after the series of 0 bits, as such the configuration within Section 8.2.2.15 “TypeBReg” on page 50 bit 4 for RxEOFReq does not exist. In addition the IC only has the possibility to select the minimum or maximum timings for SOF/EOF generation defined in ISO/IEC14443B. As such the configuration possible in version 2.0 through the EOFSOFAdjust bit (see Section 8.2.4.7 “AutoTestReg” on page 64) does not exist and the configuration is limited to only setting minimum and maximum length according ISO/IEC 14443-B, see Section 8.2.2.15 “TypeBReg” on page 50, bit 4. 21.
