PRODUCT DESCRIPTION
The SST28SF/VF040A are 512K x8 bit CMOS Sector Erase, Byte-Program EEPROMs.
The SST28SF/VF040A are manufactured using SST’s 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 SST28SF/VF040A erase and program with a
single power supply. The SST28SF/VF040A conform to JEDEC standard pinouts for
byte wide memories and are compatible with existing industry standard flash
EEPROM pinouts.
Featuring high performance programming, the SST28SF/VF040A typically Byte-
Program in 35 µs. The SST28SF/VF040A typically Sector-Erase in 2 ms. Both
Program and Erase times can be optimized using interface features such as
Toggle bit or Data# Polling to indicate the completion of the Write cycle. To
protect against an inadvertent write, the SST28SF/VF040A have on chip hardware
and Software Data Protection schemes. Designed, manufactured, and tested for a
wide spectrum of applications, the SST28SF/VF040A are offered with a
guaranteed sector endurance of 10,000 cycles. Data retention is rated greater
than 100 years.
