PRODUCT DESCRIPTION

The SST39LF200A/400A/800A and SST39VF200A/400A/800A devices are 128K x16 / 256K x16 / 512K x16 CMOS Multi-Purpose Flash (MPF) manufactured with SST 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 SST39LF200A/400A/800A write (Program or Erase) with a 3.0-3.6V power supply. The SST39VF200A/400A/800A write (Program or Erase) with a 2.7-3.6V power supply. These devices conform to JEDEC standard pinouts for x16 memories.
