DATASHEET
Chapter 1 General Description
The USB97C202 is a USB2.0 Mass Storage Class Peripheral Controller intended for use with standard
ATA-5 and -6 hard drives and standard ATAPI-5 devices.
The device consists of a USB2.0 PHY and SIE, buffers, Fast 8051 microprocessor with expanded
scratchpad and 768 of program SRAM, internal 48 KB program ROM, and an ATA-66 compatible
interface.
Provisions for optional external Flash Memory up to 64K bytes for program storage is provided. A serial
EEPROM which can be modified via USB from the host provides unique VID/PID/Serial numbers, as well
as optional configuration information.
Internal 768 Bytes of scratchpad SRAM are also provided. This internal SRAM can also be used for
program storage to implement program upgrade via USB download to external “boot block” Flash program
memory, if desired.
Seven GPIO pins are provided for controlling external power control elements and sensing specialized
drive functions. Provisions are made to allow dynamic attach and re-attach to the USB bus to allow hot
swap of drives to be implemented.
