Product Summary

The SST28SF040A-90-4C-PH is a kind of 512K x8 bit CMOS Sector-Erase, Byte-Program EEPROM. The SST28SF040A-90-4C-NH is manufactured using SST proprietary, high performance CMOS SuperFlash EEPROM Technology. The split-gate cell design and thick oxide tunneling injector attain better reliability and manufacturability compared with alternative approaches. The SST28SF040A-90-4C-PH erases and program with a single power supply. The device conforms to JEDEC standard pinouts for byte wide memories and are compatible with existing industry standard flash EEPROM pinouts.
