The 25 series Serial Flash family features a four-wire, SPI compatible interface
that allows for a low pin-count package which occupies less board space and ulti-
mately lowers total system costs. The SST25VF020B devices are enhanced with
improved
SST25VF020B SPI serial flash memories are manufactured with SST proprietary,
high performance CMOS SuperFlash technology. The split-gate cell design and
thick-oxide tunneling injector attain better reliability and manufacturability com-
pared with alternate approaches.
