The 25 series Serial Flash family features a four-wire, SPIcompatibleinterface that allows for a low pin-count packagewhich occupies less board space and ultimately lowerstotal system costs. The SST25VF020B devices areenhanced with improved operating frequency and evenlower power consumption. SST25VF020B SPI serial flashmemories are manufactured with SST proprietary, highperformanceCMOS SuperFlash technology. The split-gatecell design and thick-oxide tunneling injector attain betterreliability and manufacturability compared with alternateapproaches.
