Description

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. SST25LF020A SPI serial flash memories are manufactured with SST proprietary, high performance CMOS SuperFlash technology. The splitgate cell design and thick-oxide tunneling injector attain better reliability and manufacturability compared with alternate approaches.
