The split-gate cell design and thick oxide tunneling injector attain better reliability and manufacturability pared with alternative approaches. The SST28SF040/28LF040/28VF040 erase and program with a single power supply. The SST28SF040/28LF040/28VF040 conform to JEDEC standard pinouts for byte wide memories and are patible with existing industry standard EPROM, and flash EEPROM pinouts. Featuring high performance programming, the SST28SF040/28LF040/28VF040 typically byte program in 35 µs. The SST28SF040/28LF040/28VF040 typically sector erase in 2 ms. Both program and erase times can be optimized using interface features such as Toggle bit or...
