GENERAL DESCRIPTION

The USB97C211 is a USB2.0 Bulk Only Mass Storage Class Peripheral Controller intended for supporting

CompactFlash (CF), in True IDE Mode only, and SmartMedia (SM) flash memory devices. It provides a single chip

solution for the most popular flash memory cards in the market.*

The device consists of a USB 2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded scratchpad, and

program SRAM, and CF/SM controllers.*

Provisions for external Flash Memory up to 64K bytes for program storage is provided.

12K bytes of scratchpad SRAM and 768Bytes of program SRAM are also provided.

Sixteen GPIO pins are for the 128-pin device. Provisions are made to allow hot swap of flash media to be

implemented.

The USB97C211 supports the insertion of cards (CF, SM) simultaneously.

SMSC provides the following object code software free of charge with purchase of the USB97C211**:

Multiple LUN Mass Storage Class compliant firmware to support all media types in a single code image, with

option for firmware download via USB if a sector erasable program memory is used.

Windows application for programming VID/PID/OEM strings, and unique serial number into serial EEPROM via

USB. Serial EEPROM may be eliminated entirely if appropriate firmware and specific Flash device is used for

program code.

Firmware with field upgrade capability via USB (requires specific 128KB Flash for firmware storage).

Source code licenses are also available for USB97C211 customers.**

SMSC may make complete internal specifications available for those customers requiring programming information,
