Description
General part information
SST39LF400A Series
The SST39LF400A is a 256K 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 SST39LF400A writes (Program or Erase) with a 3.0-3.6V power supply. This device conforms to JEDEC standard pinouts for x16 memories.
