8 Mbit Firmware Hub
A Microchip Technology Company
SST49LF008A
Data Sheet
The SST49LF008A flash memory devices are designed to be read-compatible
with the Intel? 82802 Firmware Hub (FWH) device for PC-BIOS application.
These devices provide protection for the storage and update of code and data in
addition to adding system design flexibility through five general purpose inputs.
Two interface modes are supported by the SST49LF008A: Firmware Hub (FWH)
Interface mode for in-system programming and Parallel Programming (PP) mode
for fast factory programming of PC-BIOS applications.
