Microchip 4Mbit Parallel Flash Memory 32-Pin PDIP, SST39SF040-70-4C-PHE

The Microchip CMOS Multi-Purpose Flash (MPF) manufactured with SST proprietary, high performance CMOS Super Flash technology. The split-gate cell design and thick oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches. The SST39SF040 writes (Program or Erase) with a 4.5 to 5.5V power supply, and conforms to JEDEC standard pinouts for x8 memories.
