EOL Data Sheet
SST25WF512 / SST25WF010 / SST25WF020 / SST25WF040 are members of
the Serial Flash 25 Series family and feature 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. SPI serial flash memory is manufactured with
SST proprietary, high performance CMOS SuperFlash technology. The split-gate
cell design and thick-oxide tunneling injector attain better reliability and manufac-
turability compared with alternate approaches.
