SST39SF040-55-4I-NHE Datasheet

1 Mbit / 2 Mbit / 4 Mbit (x8) Multi-Purpose Flash


The SST39SF010A/020A/040 are 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 SST39SF010A/020A/040 devices write (Program or Erase) with a 4.5-5.5V power supply. The SST39SF010A/020A/040 devices conform to JEDEC standard pinouts for x8 memories.
