4 Mbit (x16) Multi-Purpose Flash Plus
SST39VF401C / SST39VF402C / SST39LF401C / SST39LF402C
Data Sheet
SST39VF401C / SST39VF402C / SST39LF401C / SST39LF402C are 256K x16
CMOS Multi-Purpose Flash Plus (MPF+) manufactured with proprietary, high per-
formance CMOS SuperFlash® technology. The split-gate cell design and thick-
oxide tunneling injector attain better reliability and manufacturability compared
with alternate approaches. SST39LF401C/402C write (Program or Erase) with a
3.0-3.6V power supply. SST39VF401C/402C write with a 2.7-3.6V power supply.
These devices conforms to JEDEC standard pinouts for x16 memories.
