Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet Chapter 1 Overview The SMSC USB2660/USB2660i is an integrated USB 2.0 compliant, Hi-Speed hub, card reader, and protocol converter combo solution. This combo solution supports today’s popular multi-format flash media cards. This multi-format flash media controller and USB hub combo features two exposed downstream USB ports available for external peripheral expansion. The dedicated flash media reader/writer is internally attached to a third downstream port of the hub as a USB Compound Device which supports the following two interfaces: One interface is multiplexed for xD-Picture Card, Memory Stick, Secure Digital/MultiMediaCard, and SD/Secure Digital Input/Output. The other interface is dedicated to a second SD card slot for SDIO bridging applications. SDIO bridging is possible with custom firmware. The USB2660/USB2660i will attach to an upstream port as a Full-Speed hub or as a Full-/Hi-Speed hub. The hub supports Low-Speed, Full-Speed, and Hi-Speed (if operating as a Hi-Speed hub) downstream devices on all of the enabled downstream ports. All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors on D+ and D– pins and all required pull-down and pull-up resistors. The over- current sense inputs for the downstream facing ports have internal pull-up resistors. The USB2660/USB2660i includes programmable features such as: PortMap which provides flexible port mapping and disable sequences. The downstream ports of a USB2660/USB2660i hub can be reordered or disabled in any sequence to support multiple platform designs with minimum effort. For any port that is disabled, the USB2660/USB2660i automatically reorders the remaining ports to match the USB host controller’s port numbering scheme. PortSwap which adds per-port programmability to USB differential- pair pin locations. PortSwap allows direct alignment of USB signals (D+/D-) to connectors avoiding uneven trace length or crossing of the USB differential signals on the PCB. PHYBoost which enables four programmable levels of USB signal drive strengths in downstream port transceivers. PHYBoost attempts to restore USB signal integrity.

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet Chapter 6 Pin Descriptions This section provides a detailed description of each signal. The signals are arranged in functional groups according to their associated interface. The pin descriptions below are applied when using the internal default firmware and can be referenced in Chapter8, "Configuration Options," on page29. Please reference Chapter2, "Acronyms," on page10 for a list of the acronyms used. The “n” symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When “n” is not present in the signal name, the signal is asserted at a high voltage level. The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a signal is active, independent of whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inactive. 6.1 USB2660/USB2660i Pin Descriptions Table6.1 USB2660/USB2660i Pin Descriptions 64-PIN BUFFER QFN TYPE SYMBOL (Table6.2) DESCRIPTION SECURE DIGITAL INTERFACE SD1_D[7:0] 27 I/O8PU Secure Digital Data 7-0 28 31 These are the bi-directional data signals SD_D0 - SD_D7 with weak 38 pull-up resistors. 40 41 25 26 SD1_CLK 29 O8 Secure Digital Clock This is an output clock signal to the SD/MMC device.

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet 6.3 Port Power Control Port Power control using a USB Power Switch The USB2660/USB2660i has a single port power control and over-current sense signal for each downstream port. When disabling port power, the driver will actively drive a '0'. To avoid unnecessary power dissipation, the internal pull-up resistor will be disabled at that time. When port power is enabled, the output driver is disabled, and the pull-up resistor is enabled creating an open drain output. If there is an over-current situation, the USB Power Switch will assert the open drain OCS signal. The Schmitt trigger input will detect this event as a low. The open drain output does not interfere. The internal over-current sense filter handles the transient conditions, such as low voltage, while the device is powering up. 5 V PRTCTL3 OCS USB Power Switch EN USB USB2660/60i Device 5 V PRTCTL2 OCS USB Power Switch EN USB Device Figure6.1 Port Power Control with USB Power Switch SMSC USB2660/USB2660i 23 Revision 1.1 (11-05-10) DATASHEET

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet Port Power control using a Poly Fuse When using the USB2660/USB2660i with a poly fuse, an external diode must be used (See Figure6.2). When disabling port power, the USB2660/USB2660i will drive a '0'. This procedure will have no effect since the external diode will isolate the pin from the load. When port power is enabled, the USB2660/USB2660i output driver is disabled, and the pull-up resistor is enabled which creates an open drain output. This open drain output condition means that the pull-up resistor is providing 3.3 volts to the anode of the diode. If there is an over-current situation, the poly fuse will open. This will cause the cathode of the diode to go to zero volts. The anode of the diode will be at 0.7 volts, and the Schmitt trigger input will register this as a low resulting in an over-current detection. The open drain output does not interfere. 5 V PRTCTL3 USB Device USB2660/60i 5V PRTCTL2 USB Device Figure6.2 Port Power Control with a Single Poly Fuse and Multiple Loads When using a single poly fuse to power all devices, note that for the ganged situation, all power control pins must be tied together. 5 V PRTCTL3 Poly Fuse USB2660/60i PRTCTL2 USB USB Device Device Figure6.3 Port Power with Ganged Control with Poly Fuse Revision 1.1 (11-05-10) 24 SMSC USB2660/USB2660i DATASHEET

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet 6.4 ROM BOOT Sequence After power-on reset, the internal firmware checks for an external SPI flash device that contains a valid signature of "2DFU" (device firmware upgrade) beginning at address 0xFFFA. If a valid signature is found, then the external ROM is enabled and code execution begins at address 0x0000 in the external SPI device. Otherwise, code execution continues from the internal ROM. If there is no SPI ROM detected, the internal firmware then checks for the presence of an I2C ROM. The firmware looks for the signature ‘ATA2’ at the offset of FCh-FFh and ‘ecf1’ at the offset of 17Ch- 17Fh in the I2C ROM. The firmware reads in the I2C ROM to configure the hardware and software internally. Please refer to Section 8.3.2, "EEPROM Data Descriptor," on page30 for the details of the configuration options. The SPI ROM required for the USB2660/USB2660i is a recommended minimum of 1 Mbit and support either 30 MHz or 60 MHz. The frequency used is set using the SPI_SPD_SEL. For 30 MHz operation, this pin must be pulled to ground through a 100 kΩ resistor. For 60 MHz operation, this pin must pulled up through a 100 kΩ resistor. The SPI_SPD_SEL pin is used to choose the speed of the SPI interface. During nRESET assertion, this pin will be tri-stated with the weak pull-down resistor enabled. When nRESET is negated, the value on the pin will be internally latched, and the pin will revert to SPI_DO functionality. The internal pull- down will be disabled. The firmware can determine the speed of operation on the SPI port by checking the SPI_SPEED in the SPI_CTL register (0x2400 - RESET = 0x02). Both 1- and 2-bit SPI operation is supported. For optimum throughput, a 2-bit SPI ROM is recommended. Both mode 0 and mode 3 SPI ROMS are also supported.

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet Chapter 8 Configuration Options 8.1 Hub SMSC’s USB 2.0 hub is fully compliant to the Universal Serial Bus Specification available from the USB Implementer’s Forum found at http://www.usb.org (Revision 2.0 April 27, 2000 and the 12/7/2000 and 5/28/2002 Errata). Please reference Chapter 11 (Hub Specification) for general details regarding hub operation and functionality. For performance reasons, the hub provides 1 transaction translator (TT) that is shared by both downstream ports defined as a single-TT configuration. The TT contains 4 non-periodic buffers. 8.1.1 Hub Configuration Options The SMSC hub supports a large number of features (some are mutually exclusive), and must be configured in order to correctly function when attached to a USB host controller. There are two principal ways to configure the hub: (cid:132) via the internal default settings or (cid:132) by settings stored in an external EEPROM or SPI Flash device. 8.1.1.1 Power Switching Polarity The hub will only support active high power controllers. 8.1.2 VBus Detect According to Section 7.2.1 of the USB 2.0 Specification, a device cannot provide power to its D+ or D- pull-up resistors unless the upstream port’s VBUS is in the asserted (powered) state. The VBUS_DET pin on the hub monitors the state of the upstream VBUS signal and will not pull-up the D+ resistor if VBUS is not active. If VBUS goes from an active to an inactive state (not powered), the hub will remove power from the D+ pull-up resistor within 10 seconds. 8.2 Card Reader The SMSC USB2660/USB2660i is fully compliant with the following flash media card reader specifications: (cid:132) Secure Digital 2.0 / MultiMediaCard 4.2 -SD 2.0, HS-SD, HC-SD -TransFlash™ and reduced form factor media -1/4/8 bit MMC 4.2 (cid:132) Memory Stick 1.43 (cid:132) Memory Stick Pro Format 1.02 (cid:132) Memory Stick Pro-HG Duo Format 1.01 -Memory Stick, MS Duo, HS-MS, MS Pro-HG, MS Pro (cid:132) Memory Stick Duo 1.10 (cid:132) xD-Picture Card 1.2 SMSC USB2660/USB2660i 29 Revision 1.1 (11-05-10) DATASHEET

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet 8.3 System Configurations 8.3.1 EEPROM/SPI Interface The USB2660/USB2660i can be configured via a 2-wire (I2C) EEPROM (512x8) or an external SPI flash device containing the firmware for the USB2660/USB2660i. If an external configuration device does not exist the internal default values will be used. If one of the external devices is used for configuration, the OEM can update the values through the USB interface. The hub will then “attach” to the upstream USB host. The USBDM tool set is available in the USB264x Hub Card reader combo software release package.

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet 8.4.3.7 D3h: Dynamic Number of LUNs BIT NAME DESCRIPTION 7:0 DYN_NUM_LUN These bytes are used to specify the number of LUNs the device exposes to the host. These bytes are also used for icon sharing by assigning more than one LUN to a single icon. This is used in applications where the device utilizes a combo socket and the OEM wishes to have only a single icon displayed for one or more interfaces. If this field is set to "FF", the program assumes that you are using the default value and icons will be configured per the default configuration. 8.4.3.8 D4h-D7h: Device to LUN Mapping BYTE NAME DESCRIPTION 3:0 DEV_LUN_MAP These registers map a device controller (SD/MMC, SM (Note8.2), and MS) to a Logical Unit Number (LUN). The device reports the mapped LUNs to the USB host in the USB descriptor during enumeration. The icon installer associates custom icons with the LUNs specified in these fields. Setting a register to "FF" indicates that the device is not mapped. Setting all of the DEV_LUN_MAP registers for all devices to "FF" forces the use of the default mapping configuration. Not all configurations are valid. Valid configurations depend on the hardware, packaging, and OEM board layout.

The hub is either self-powered (draws less than 2 mA of upstream bus power) or bus-powered (limited to a 100 mA maximum of upstream power prior to being configured by the host controller). When configured as a bus-powered device, the SMSC hub consumes less than 100 mA of current prior to being configured. After configuration, the bus- powered SMSC hub (along with all associated hub circuitry, any embedded devices if part of a compound device, and 100 mA per externally available downstream port) must consume no more than 500 mA of upstream VBUS current. The current consumption is system dependent, and the OEM must ensure that the USB 2.0 specifications are not violated. When configured as a self-powered device, <1 mA of upstream VBUS current is consumed and all ports are available, with each port being capable of sourcing 500 mA of current. ‘0’ = Bus-powered operation ‘1’ = Self-powered operation 6 Reserved Reserved 5 HS_DISABLE Hi-Speed Disable: Disables the capability to attach as either a Hi-/Full-Speed device, and forces attachment as Full-Speed only (i.e. no Hi-Speed support). ‘0’ = Hi-/Full-Speed ‘1’ = Full-Speed-Only (Hi-Speed disabled!)

Not all configurations are valid. Valid configurations depend on the hardware, packaging, and OEM board layout. The number of unique LUNs mapped must match the value in the Section 8.4.3.7, "D3h: Dynamic Number of LUNs," on page41. 8.4.5.10 14Ch-14Dh: Second Secure Digital Device Power Configuration The device has two internal FETs which can be utilized for card power. For information about the other internal FET, please see Section 8.4.2.3, "A4h-A5h: Smart Media Device Power Configuration," on page39. The settings are stored in NVSTORE. This section describes the default internal configuration. 1. A card can be powered by an external FET or by an internal FET. 2. The power limit can be set to 100 mA or 200 mA (Default) for the internal FET. Each media uses two bytes to store its device power configuration. Bit 3 selects between internal or external card power FET options. For internal FET card power control, bits 0 through 2 are used to set the power limit. The “Device Power Configuration” bits are ignored unless the “Enable Device Power Configuration” bit is set. See Section 8.4.1.19, "9Ch-9Fh: Attribute Byte Descriptions," on page37.

The signature must be set to 'ecf1'. 8.4.6 I2C EEPROM The I2C EEPROM interface implements a subset of the I2C Master Specification (Please refer to the Philips Semiconductor Standard I2C-Bus Specification for details on I2C bus protocols). The device’s I2C EEPROM interface is designed to attach to a single “dedicated” I2C EEPROM, and it conforms to the Standard-mode I2C Specification (100 kbps transfer rate and 7-bit addressing) for protocol and electrical compatibility. Note: Extensions to the I2C Specification are not supported. The device acts as the master and generates the serial clock SCL, controls the bus access (determines which device acts as the transmitter and which device acts as the receiver), and generates the START and STOP conditions. 8.4.6.1 Implementation Characteristics The device will only access an EEPROM using the sequential read protocol. 8.4.6.2 Pull-Up Resistor The circuit board designer is required to place external pull-up resistors (10 kΩ recommended) on the SPI_DO / GPIO5 / SDA / SPI_SPD_SEL and SPI_CLK / GPIO4 / SCL lines (per SMBus 1.0 Specification and EEPROM manufacturer guidelines) to VDD33 in order to assure proper operation. 8.4.7 In-Circuit EEPROM Programming The EEPROM can be programmed via automatic test equipment (ATE). Pulling nRESET low tri-states the device’s EEPROM interface and allows an external source to program the EEPROM. SMSC USB2660/USB2660i 53 Revision 1.1 (11-05-10) DATASHEET

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet 8.5 Default Configuration Option The SMSC device can be configured via its internal default configuration. Please see Section 8.3.2, "EEPROM Data Descriptor" for specific details on how to enable default configuration. Please refer to Table8.1 for the internal default values that are loaded when this option is selected. 8.5.1 External Hardware nRESET A valid hardware reset is defined as assertion of nRESET for a minimum of 1 μs after all power supplies are within operating range. While reset is asserted, the device (and its associated external circuitry) consumes less than 500 μA of current from the upstream USB power source. Assertion of nRESET (external pin) causes the following: 1. All downstream ports are disabled and PRTCTL power to downstream devices is removed. 2. The PHYs are disabled and the differential pairs will be in a high-impedance state. 3. All transactions immediately terminate; no states are saved. 4. All internal registers return to the default state (in most cases, 00h). 5. The external crystal oscillator is halted. 6. The PLL is halted. 8.5.1.1 nRESET for EEPROM Configuration Start Hardware Device 8051 Sets Attach USB Reset completion reset Recovery/ Configuration USB Idle recovery request asserted Stabilization Registers Upstream response t4 t1 t2 t3 t5 t6 t7 nRESET VSS Figure8.1 nRESET Timing for EEPROM Mode Table8.7 nRESET Timing for EEPROM Mode NAME DESCRIPTION MIN TYP MAX UNITS t1 nRESET asserted 1 μsec t2 Device recovery/stabilization 500 μsec t3 8051 programs device configuration 20 50 msec t4 USB attach (See Note) 100 msec t5 Host acknowledges attach and signals USB reset 100 msec t6 USB idle Undefined msec t7 Completion time for requests (with or without data 5 msec stage) Revision 1.1 (11-05-10) 54 SMSC USB2660/USB2660i DATASHEET

Ultra Fast USB 2.0 Hub and Multi-Format Flash Media Controller with Dual SD Interfaces Datasheet Note: All power supplies must have reached the operating levels mandated in Chapter10, DC Parameters, prior to (or coincident with) the assertion of nRESET. 8.5.2 USB Bus Reset In response to the upstream port signaling a reset to the device, the device does the following: Note: The device does not propagate the upstream USB reset to downstream devices. 1. Sets default address to ‘0’. 2. Sets configuration to: Unconfigured. 3. Negates PRTCTL[3:2] to all downstream ports. 4. Clears all TT buffers. 5. Moves device from suspended to active (if suspended). 6. Complies with Section 11.10 of the USB 2.0 Specification for behavior after completion of the reset sequence. The host then configures the device and the device’s downstream port devices in accordance with the USB 2.0 Specification. SMSC USB2660/USB2660i 55 Revision 1.1 (11-05-10) DATASHEET
