PRODUCT DESCRIPTION

The SST29SF512/010/020/040 and SST29VF512/010/ 020/040 are 64K x8 / 128K x8 / 256K x8 / 512K x8 CMOS Small-Sector Flash (SSF) 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 SST29SFxxx devices write (Program or Erase) with a 4.5-5.5V power supply. The SST29VFxxx devices write (Program or Erase) with a 2.7- 3.6V power supply. These devices conform to JEDEC standard pinouts for x8 memories.
