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. The SST49LF160C uses a 5-signal LPC interface to support both in-system and rapid factory programming using programmer equipment. A high voltage pin (WP#/AAI) is used to enable Auto Address Increment (AAI) mode. The SST49LF160C offers hardware block protection in addition to individual block protection via software registers for critical system code and data.
