PRODUCT DESCRIPTION
The SST29EE/LE/VE020 are 256K x8 CMOS Page-Write EEPROM 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 SST29EE/LE/VE020 write with a single power supply. Internal Erase/Program is transparent to the user. The SST29EE/LE/VE020 conform to JEDEC standard pinouts for byte-wide memories.
