The SST49LF160C flash memory device is designed to interface with host controllers (chipsets) that support a lowpin-count (LPC) interface for system firmware applications.The SST49LF160C device complies with the LPC Interface Specification. The LPC interface operates with 5 signal pins versus 32 pins of a 8-bit parallel flash memory. This frees up pins on the ASIC host controller resulting in lower ASIC costs and a reduction in overall system costs due to simplified signal routing.
