The SST serial flash family features a four-wire, SPI-compatibleinterface that allows for a low pin-count package occupying less board space and ultimately loweringtotal system costs. SST25VF020B-80-4I-Q3AE-T SPI serial flash memoriesare manufactured with SST proprietary, high performanceCMOS SuperFlash Technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternateapproaches.
