SPI Serial Flash memory is manufac- - Active Read Current: 4 mA (typical) tured with proprietary, high performance CMOS SuperFlash technology. The split-gate cell design and - Standby Current: 10 A (typical) thick-oxide tunneling injector attain better reliability and - Power-down Mode Standby Current: 4 A (typical) manufacturability compared with alternate approaches. Flexible Erase Capability This Serial Flash significantly improves performance - Uniform 4 KByte sectors and reliability, while lowering power consumption. The - Uniform 64 KByte overlay blocks device writes (Program or Erase) with a single power Page Program Mode supply of 1.65-1.95V. The total energy consumed is a - 256 Bytes/Page function of the applied voltage, current, and time of Fast Erase and Page-Program: application. Since for any given voltage range, the SuperFlash technology uses less current to program - Chip-Erase Time: 300 ms (typical) and has a shorter erase time, the total energy con- - Sector-Erase Time: 40 ms (typical) sumed during any Program or Erase operation is less - Block-Erase Time: 80 ms (typical) than alternative Flash memory technologies. - Page-Program Time: 3 ms/ 256 bytes (typical) SST25WF020A is offered in 8-lead SOIC, 8-contact End-of-Write Detection USON, and 8-contact WDFN packages.
