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 proprietary, high-performance SuperFlash® Technology. The split-

gate cell design and thick-oxide tunneling injector attain better reliability and man-

ufacturability compared with alternate approaches
