A49LF004 Description
The A49LF004 flash memory device is designed to be readpatible with the Intel 82802 Firmware Hub (FWH) device for PC-BIOS application. This device is designed to use a single low voltage, range from 3.0 Volt to 3.6 Volt power supply to perform in-system or off-system read and write operations. It provides protection for the storage and update of code and data in addition to adding system design flexibility through...
