Product Summary

The 39VF040 is a 512 Kbit/1 Mbit/2 Mbit/4 Mbit (x8) 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 39VF040 writes with a 2.7-3.6V power supply. The device conforms to JEDEC standard pinouts for x8 memories. Featuring high performance Byte-Program, the 39VF040 provides a maximum Byte-Program time of 20μsec. The device uses Toggle Bit or Data# Polling to indicate the completion of Program operation.
