SST39SF020 - Silicon Storage Technology

SST39SF020 2 Megabit (256K x 8) Multi-Purpose Flash

The SST39SF020 is a 256K x 8 CMOS Multi-Purpose Flash (MPF) manufactured with SST’s 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 SST39SF020 device writes (Program or Erase) with a 5.0V-only power s.
