16 Mbit LPC Flash
SST49LF160C
EOL Data Sheet
SST49LF160C flash memory device is designed to interface with host controllers
(chipsets) that support a low pin-count (LPC) interface for system firmware appli-
cations. 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.
