A Microchip Technology Company
Not Recommended for New Designs
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. SST25VF020 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 manufacturability compared with alternate approaches.
