PRODUCT DESCRIPTION
The SST49LF004B flash memory devices are designed to interface with host
controllers (chipsets) that support a low pin-count (LPC) interface for BIOS
applications. The SST49LF004B devices comply with Intel’s LPC Interface
Specification, supporting single-byte Firmware Memory cycle type.
The SST49LF004B devices are backward compatible to the SST49LF004A Firmware
Hub. In this document, FWH mode in the SST49LF004A specification is referenced
as the Firmware Memory Read/Write cycle. Two interface modes are supported by
the SST49LF004B: LPC mode (Firmware Memory cycle types) for in-system
operations and Parallel Programming (PP) mode to interface with programming
equipment.
