PRODUCT DESCRIPTION

The SST49LF00xC flash memory devices are designed to interface with host controllers (chipsets) that support a low pin-count (LPC) interface for system firmware applications. The SST49LF00xC device complies with Intel’s LPC Interface Specification 1.1, supporting a Burst-Read (up to 128 bytes in a single operation) which enables a 15.6 MByte per second data transfer. The LPC interface operates with 5 signal pins versus 28 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.
