All devices are RoHS compliant
The SST39VF6401B / SST39VF6402B devices are 4M x16, CMOS Multi-Purpose
Flash Plus (MPF+) manufactured with SST proprietary, high performance CMOS
SuperFlash technology. The split-gate cell design and thick-oxide tunneling injec-
tor attain better reliability and manufacturability compared with alternate
approaches. The SST39VF6401B / SST39VF6402B write (Program or Erase)
with a 2.7-3.6V power supply. These devices conform to JEDEC standard pinouts
for x16 memories and are command set compatible with other Flash devices,
enabling customers to save time and resources in implementation.
Not recommended for new designs.
