SST49LF008A-33-4C-WHE Product Details

The SST49LF008A-33-4C-WHE 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.
