16 Mbit LPC Serial Flash
SST49LF016C
The SST49LF016C flash memory device is designed to interface with host con-
trollers (chipsets) that support a low pin-count (LPC) interface for system firmware
applications. Complying with LPC Interface Specification 1.1, SST49LF016C sup-
ports a Burst-Read data transfer of 15.6 MBytes per second at 33 MHz clock
speed and 31.2 MBytes per second at 66 MHz clock speed, up to 128 bytes in a
single operation
