Description
The SST49LF004B-33-4C-NH is an electronic component belonging to the IC Chips category. It is a flash memory device designed to interface with host controllers (chipsets) that support a low pin-count (LPC) interface for BIOS applications. The SST49LF004B-33-4C-NH complies with Intel's LPC Interface Specification 1.1 and supports single-byte Firmware Memory and LPC Memory cycle types. It is backward compatible with the SST49LF00xA Firmware Hub and the SST49LF0x0A LPC Flash.
