64 Mbit (x16) Multi-Purpose Flash Plus

A Microchip Technology Company

SST39VF6401B / SST39VF6402B

Not Recommended for New Designs

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.
