TM (SD) and Multi Media Card TM (MMC) interface on one chip.
l Complies with 480Mbps Universal Serial Bus specification rev. 2.0.
l Complies with USB Storage Class specification rev. 1.0. (Bulk only protocol).
l Operating System supported: Win XP/ 2000/ Me/ 98/ 98SE; Mac OS 9.x/ X.
l Supports 1 device address and up to 10 endpoints: Control (0)/ Bulk Read (1)/ Bulk Write (2)/ Interrupt (3),
and 3 optional Bulk Read/ Write endpoints pair.
l Integrated USB 2.0 Transceiver Macrocell Interface (UTMI) transceiver and Serial Interface Engine (SIE).
l Integrated 8051 micro-controller with enhanced feature:
- Supports 48MHz clock rate.
- 12 clocks per instruction cycle.
- Embedded 24KB Mask ROM and 2KB+256B SRAM.
- Supports external 64KB ROM/ Flash for design flexibility.
l Supports firmware upgrade via USB interface.
l Supports external flash read/ write for firmware upgrade and other applications.
l Supports serial EEPROM 93C86 interface for the flexibility of vendor or firmware parameters, EEPROM
size up to 2KB.
l High efficiency card interface hardware engine for data transfer.
l Shared pins between PCMCIA and SmartMediaTM interface.
l PCMCIA interface:

- Supports hardware BS/SDIO/SCLK signals.
- Supports INS signal.
- Supports automatic CRC16 generation and verification.
- Supports hardware CMD timeout detection.
- Supports different clock rate up to 24 MHz.
l Secure DigitalTM/ Multi Media CardTM interface:
- Complies with Secure Digital / MMC interface specification.
- Supports both SD / MMC mode access: CLK/CMD/DAT0/DAT1/DAT2/DAT3.
- Command transmit and response receive can be enabled separately.
- Automatic CRC7 generation for command and CRC7 verification for response on CMD.
- Supports automatic CRC16 generation and verification on DAT3-0.
- In addition to full packet transaction, optional single byte/ bit operation on both CMD and DAT line/ lines.
