Description

The USB97C201 is a USB2.0 Mass Storage Class Peripheral Controller intended for use with standard ATA hard drives and standard ATAPI-5 devices.
The USB97C201 and 768 of program SRAM, and an ATA-66 compatible interface. Provisions for external Flash Memory up to 64K bytes for program storage is provided. Internal 768 Bytes of program SRAM are also provided.. This internal SRAM is used for program storage to implement program upgrade via USB download to "boot block" Flash program memory, if desired. Eight 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.
