PRODUCT DESCRIPTION

The SST39LF512, SST39LF010,SST39LF020, SST39LF040 and SST39VF512, SST39VF010,SST39VF020, SST39VF040 are 64K x8, 128K x8, 256K x8 and 5124K x8 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 SST39LF512/010/020/040 devices write (Program or Erase) with a 3.0-3.6V power supply. The SST39VF512/010/020/040 devices write with a 2.7-3.6V power supply. The devices conform to JEDEC standard pinouts for x8 memories.
