SST49LF003A - Silicon Storage Technology

SST49LF003A 2 Mbit / 3 Mbit / 4 Mbit / 8 Mbit Firmware Hub

The SST49LF00xA flash memory devices are designed to be read-compatible with the Intel 82802 Firmware Hub (FWH) device for PC-BIOS application. It provides 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 SST49LF00xA: Firmware H.
