The SST39LVF040 is a 5124K x8CMOS Multi-Purpose Flash (MPF) manufactured with SST proprietary, high performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The SST39LF040 device writes (Program or Erase) with a 3.0-3.6V power supply. The device conforms to JEDEC standard pinouts for x8 memories.
