A Microchip Technology Company
SST’s serial flash family features a four-wire, SPI-compatible interface that allows
for a low pin-count package occupying less board space and ultimately lowering
total system costs. SST25VF512A SPI serial flash memory is manufactured with
SST’s proprietary, high-performance CMOS SuperFlash technology. The split-
gate cell design and thick-oxide tunneling injector attain better reliability and man-
ufacturability compared with alternate approaches.
