The SST39SF010A / SST39SF020A / SST39SF040 are CMOS Multi-Purpose
Flash (MPF) devices manufactured with SST proprietary, high performance
CMOS SuperFlash technology. The split-gate cell design and thick oxide tunnel-
ing injector attain better reliability and manufacturability compared with alternate
approaches. The SST39SF010A / SST39SF020A / SST39SF040 write (Program
or Erase) with a 4.5-5.5V power supply, and conforms to JEDEC standard pinouts
for x8 memories
