8 Mbit LPC Flash
SST49LF080A
The SST49LF080A flash memory device is designed to interface with the LPC
bus for PC and Internet Appliance application in compliance with Intel Low Pin
Count (LPC) Interface Specification 1.0. Two interface modes are supported: LPC
mode for in-system operations and Parallel Programming (PP) mode to interface
with programming equipment. The SST49LF080A flash memory device is manu-
factured with SST's proprietary, high-performance SuperFlash® Technology. The
split-gate cell design and thick-oxide tunneling injector attain better reliability and
manufacturability compared with alternate approaches
