詳細說明
PRODUCT DESCRIPTIONThe 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
