PRODUCT DESCRIPTION
The SST serial flash family features a four-wire, SPI compatible interface that allows for a low pin-count pack age occupying less board space and ultimately lowering total system costs. SST25VF020 SPI serial flash memories are manufactured with SST’s proprietary, high performance CMOS SuperFlash Technology. The split-gate cell design and thick-oxide tunneling injector attain bette reliability and manufacturability compared with alternate approaches.
