49LF004B Overview
The SST49LF004B flash memory device is designed to interface with host controllers (chipsets) that support a lowpin-count (LPC) interface for BIOS applications. The SST49LF004B device plies with Intel’s LPC Interface Specification 1.1, supporting single-byte Firmware Memory and LPC Memory cycle types. The SST49LF004B is backward patible to the SST49LF00xA Firmware Hub and the SST49LF0x0A LPC Flash.
