The SST49LF008A-33-4C-NHE is a 8MB Flash Memory designed to be read-compatible with the Intel® 82802 Firmware Hub (FWH) device for PC-BIOS application. This device 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 SST49LF008A - Firmware Hub (FWH) interface mode for in-system programming and parallel programming (PP) mode for fast factory programming of PC-BIOS applications. The flash memory device is manufactured with SSTs proprietary, high performance SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The device significantly improves performance and reliability, while lowering power consumption. It uses less energy during erase and program than alternative flash memory technologies.
