CY8C20xx7/S PSoC® Functional Overview Figure 1. CapSense System Block Diagram The PSoC family consists of many devices with on-chip CS1 controllers. These devices are designed to replace multiple traditional MCU-based system components with one low-cost IDAC single-chip programmable component. A PSoC device includes s CS2 configurable blocks of analog and digital logic, and Bu programmable interconnect. This architecture makes it possible bal o for you to create customized peripheral configurations, to match Gl the requirements of each individual application. Additionally, a og fast central processing unit (CPU), flash program memory, nal CSN A SRAM data memory, and configurable I/O are included in a Vr range of convenient pinouts. The architecture for this device family, as shown in the “Logic Reference Block Diagram” on page2, consists of three main areas: Buffer ■The core ■CapSense analog system Comparator Cexternal (P0[1] Mux or P0[3]) ■System resources Mux Refs A common, versatile bus allows connection between I/O and the analog system. Each CY8C20x37/47/67/S PSoC device includes a dedicated CapSense block that provides sensing and scanning control Cap Sense Counters circuitry for capacitive sensing applications. Depending on the PSoC package, up to 34 GPIOs are also included. The GPIOs provide access to the MCU and analog mux. CSCLK PSoC Core IMO CapSense Oscillator Clock Select The PSoC core is a powerful engine that supports a rich instruction set. It encompasses SRAM for data storage, an interrupt controller, sleep and watchdog timers, and IMO and ILO. The CPU core, called the M8C, is a powerful processor with Analog Multiplexer System speeds up to 24 MHz. The M8C is a 4-million instructions per second (MIPS), 8-bit Harvard-architecture microprocessor. The analog mux bus can connect to every GPIO pin. Pins are connected to the bus individually or in any combination. The bus CapSense System also connects to the analog system for analysis with the The analog system contains the capacitive sensing hardware. CapSense block comparator. Several hardware algorithms are supported. This hardware Switch-control logic enables selected pins to precharge performs capacitive sensing and scanning without requiring continuously under hardware control. This enables capacitive external components. The analog system is composed of the measurement for applications such as touch sensing. Other CapSense PSoC block and an internal 1 V or 1.2 V analog multiplexer applications include: reference, which together support capacitive sensing of up to 31 inputs[2]. Capacitive sensing is configurable on each GPIO pin. ■Complex capacitive sensing interfaces, such as sliders and Scanning of enabled CapSense pins is completed quickly and touchpads. easily across multiple ports. ■Chip-wide mux that allows analog input from any I/O pin. SmartSense™ Auto-tuning ■Crosspoint connection between any I/O pin combinations. SmartSense auto-tuning is an innovative solution from Cypress that removes manual tuning of CapSense applications. This solution is easy to use and provides robust noise immunity. It is the only auto-tuning solution that establishes, monitors, and maintains all required tuning parameters of each sensor during run time. SmartSense auto-tuning allows engineers to go from prototyping to mass production without retuning for manufacturing variations in PCB and/or overlay material properties.

CapSense running at 6 MHz, – 1.16 1.80 mA DD6 no I/O sourcing current I [40, 41, 42, 43] Deep sleep current V  3.0 V, T = 25 °C, I/O regulator turned off – 0.10 1.1 A SB0 DD A I [40, 41, 42, 43] Standby current with POR, LVD V  3.0 V, T = 25 °C, I/O regulator turned off – 1.07 1.50 A SB1 and sleep timer DD A I [40, 41, 42, 43] Standby current with I2C Conditions are VDD = 3.3 V, TA = 25 °C and – 1.64 – A SBI2C enabled CPU = 24 MHz Notes 37.When VDD remains in the range from 1.71 V to 1.9 V for more than 50 µs, the slew rate when moving from the 1.71 V to 1.9 V range to greater than 2 V must be slower than 1 V/500 µs to avoid triggering POR. The only other restriction on slew rates for any other voltage range or transition is the SRPOWER_UP parameter. 38. If powering down in standby sleep mode, to properly detect and recover from a VDD brown out condition any of the following actions must be taken: a. Bring the device out of sleep before powering down. b. Assure that VDD falls below 100 mV before powering back up. c. Set the No Buzz bit in the OSC_CR0 register to keep the voltage monitoring circuit powered during sleep. d. Increase the buzz rate to assure that the falling edge of VDD is captured. The rate is configured through the PSSDC bits in the SLP_CFG register. For the referenced registers, refer to the Technical Reference Manual. In deep sleep/standby sleep mode, additional low power voltage monitoring circuitry allows VDD brown out conditions to be detected and resets the device when VDD goes lower than 1.1 V at edge rates slower than 1 V/ms. 39.For proper CapSense block functionality, if the drop in VDD exceeds 5% of the base VDD, the rate at which VDD drops should not exceed 200 mV/s. Base VDD can be between 1.8 V and 5.5 V. 40.Errata: When programmable timer 0 is used in “one-shot” mode by setting bit 1 of register 0,B0h (PT0_CFG), and the timer interrupt is used to wake the device from sleep, the interrupt service routine (ISR) may be executed twice. For more information, see the “Errata” on page38. 41.Errata: When in sleep mode, if a GPIO interrupt happens simultaneously with a Timer0 or Sleep Timer interrupt, the GPIO interrupt may be missed, and the corresponding GPIO ISR not run. For more information, see the “Errata” on page38. 42.Errata: If an interrupt is posted a short time (within 2.5 CPU cycles) before firmware commands the device to sleep, the interrupt will be missed. For more information, see the “Errata” on page38. 43.Errata: Device wakes up from sleep when an analog interrupt is trigger. For more information, see the “Errata” on page38.

CY8C20xx7/S Numeric Naming Hexadecimal numbers are represented with all letters in uppercase with an appended lowercase ‘h’ (for example, ‘14h’ or ‘3Ah’). Hexadecimal numbers may also be represented by a ‘0x’ prefix, the C coding convention. Binary numbers have an appended lowercase ‘b’ (for example, 01010100b’ or ‘01000011b’). Numbers not indicated by an ‘h’, ‘b’, or 0x are decimal. Glossary Crosspoint connection Connection between any GPIO combination via analog multiplexer bus. Differential non linearity Ideally, any two adjacent digital codes correspond to output analog voltages that are exactly one LSB apart. Differential non-linearity is a measure of the worst case deviation from the ideal 1 LSB step. Hold time Hold time is the time following a clock event during which the data input to a latch or flip- flop must remain stable in order to guarantee that the latched data is correct. I2C It is a serial multi-master bus used to connect low speed peripherals to MCU. Integral nonlinearity It is a term describing the maximum deviation between the ideal output of a DAC/ADC and the actual output level. Latch-up current Current at which the latch-up test is conducted according to JESD78 standard (at 125 degree Celsius) Power supply rejection ratio (PSRR) The PSRR is defined as the ratio of the change in supply voltage to the corresponding change in output voltage of the device. Scan The conversion of all sensor capacitances to digital values. Setup time Period required to prepare a device, machine, process, or system for it to be ready to function. Signal-to-noise ratio The ratio between a capacitive finger signal and system noise. SPI Serial peripheral interface is a synchronous serial data link standard.

CY8C20xx7/S Errata This section describes the errata for the CY8C20xx7/S family. Details include errata trigger conditions, scope of impact, available workaround, and silicon revision applicability. Contact your local Cypress Sales Representative if you have questions. CY8C20xx7/S Qualification Status Product Status: Production released. CY8C20xx7/S Errata Summary The following Errata items apply to the CY8C20xx7/S datasheet 001-69257. 1.DoubleTimer0 ISR ■Problem Definition When programmable timer 0 is used in “one-shot” mode by setting bit 1 of register 0,B0h (PT0_CFG), and the timer interrupt is used to wake the device from sleep, the interrupt service routine (ISR) may be executed twice. ■Parameters Affected No datasheet parameters are affected. ■Trigger Condition(S) Triggered by enabling one-shot mode in the timer, and using the timer to wake from sleep mode. ■Scope of Impact The ISR may be executed twice. ■Workaround In the ISR, firmware should clear the one-shot bit with a statement such as “and reg[B0h], FDh” ■Fix Status Will not be fixed ■Changes None 2.Missed GPIO Interrupt ■Problem Definition When in sleep mode, if a GPIO interrupt happens simultaneously with a Timer0 or Sleep Timer interrupt, the GPIO interrupt may be missed, and the corresponding GPIO ISR not run. ■Parameters Affected No datasheet parameters are affected. ■Trigger Condition(S) Triggered by enabling sleep mode, then having GPIO interrupt occur simultaneously with a Timer 0 or Sleep Timer interrupt. ■Scope of Impact The GPIO interrupt service routine will not be run. ■Workaround The system should be architected such that a missed GPIO interrupt may be detected. For example, if a GPIO is used to wake the system to perform some function, the system should detect if the function is not performed, and re-issue the GPIO interrupt. Alternatively, if a GPIO interrupt is required to wake the system, then firmware should disable the Sleep Timer and Timer0. Alternatively, the ISR’s for Sleep Timer and Timer0 should manually check the state of the GPIO to determine if the host system has attempted to generate a GPIO interrupt. ■Fix Status Will not be fixed ■Changes None Document Number: 001-69257 Rev. *Q Page 38 of 46

CY8C20xx7/S 3.Missed Interrupt During Transition to Sleep ■Problem Definition If an interrupt is posted a short time (within 2.5 CPU cycles) before firmware commands the device to sleep, the interrupt will be missed. ■Parameters Affected No datasheet parameters are affected. ■Trigger Condition(S) Triggered by enabling sleep mode just prior to an interrupt. ■Scope of Impact The relevant interrupt service routine will not be run. ■Workaround None. ■Fix Status Will not be fixed ■Changes None 4.Wakeup from sleep with analog interrupt ■Problem Definition Device wakes up from sleep when an analog interrupt is trigger ■Parameters Affected No datasheet parameters are affected. ■Trigger Condition(S) Triggered by enabling analog interrupt during sleep mode when device operating temperature is 50 °C or above ■Scope of Impact Device unexpectedly wakes up from sleep ■Workaround Disable the analog interrupt before entering sleep and turn it back on upon wake-up. ■Fix Status Will not be fixed ■Changes None Document Number: 001-69257 Rev. *Q Page 39 of 46

CY8C20xx7/S 5.Wake-up from Sleep with Hardware I2C Address match on Pins P1[0], P1[1] ■Problem Definition I2C interface needs 20 ns hold time on SDA line with respect to falling edge of SCL, to wake-up from sleep using I2C hardware address match event. ■Parameters Affected t increased to 20 ns from 0 ns HD;DAT ■Trigger Condition(S) This is an issue only when all these three conditions are met: 1) P1.0 and P1.1 are used as I2C pins, 2) Wakeup from sleep with hardware address match feature is enabled, and 3) I2C master does not provide 20 ns hold time on SDA with respect to falling edge of SCL. ■Scope of Impact These trigger conditions cause the device to never wake-up from sleep based on I2C address match event. ■Workaround For a design that meets all of the trigger conditions, the following suggested circuit has to be implemented as a work-around. The R and C values proposed are 100ohm and 200pF respectively. ■Fix Status Will not be fixed ■Changes None Document Number: 001-69257 Rev. *Q Page 40 of 46

CY8C20xx7/S 6.I2C Port Pin Pull-up Supply Voltage ■Problem Definition Pull-up resistor on I2C interface cannot be connected to a supply voltage that is greater than 0.7V of CY8C20xx7/S V . DD ■Parameters Affected None. ■Trigger Condition(S) This problem occurs only when the I2C master is powered at a higher voltage than CY8C20xx7/S. ■Scope of Impact This trigger condition will corrupt the I2C communication between the I2C host and the CY8C20xx7/S CapSense controller. ■Workaround I2C master cannot be powered at a supply voltage that is greater than 0.7V compared to CY8C20xx7/S supply voltage. ■Fix Status Will not be fixed ■Changes None 7.Port1 Pin Voltage ■Problem Definition Pull-up resistor on port1 pins cannot be connected to a voltage that is greater than 0.7V higher than CY8C20xx7/S V . DD ■Parameters Affected None. ■Trigger Condition(S) This problem occurs only when port1 pins are at voltage 0.7V higher than V of CY8C20xx7/S. DD ■Scope of Impact This trigger condition will not allow CY8C20xx7/S to drive the output signal on port1 pins, input path is unaffected by this condition. ■Workaround Port1 should not be connected to a higher voltage than V of CY8C20xx7/S. DD ■Fix Status Will not be fixed ■Changes None Document Number: 001-69257 Rev. *Q Page 41 of 46
