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. SST25VF020 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.

   Serial Interface Architecture– SPI Compatible: Mode 0 and Mode 3

   Superior Reliability– Endurance: 100,000 Cycles (typical)– Greater than 100 years Data Retention

   Low Power Consumption:– Active Read Current: 7 mA (typical)– Standby Current: 8 µA (typical)

   Flexible Erase Capability– Uniform 4 KByte sectors– Uniform 32 KByte overlay blocks

   Fast Erase and Byte-Program:– Chip-Erase Time: 70 ms (typical)– Sector- or Block-Erase Time: 18 ms (typical)– Byte-Program Time: 14 µs (typical)

   Auto Address Increment (AAI) Programming– Decrease total chip programming time overByte-Program operations
