Description
SST’s 25 series Serial Flash family features a four-wire, SPI-compatible interface that allows for a low pin-count package which occupies less board space and ultimately lowers total system costs. The SST25VF080B-80-4I-S2AE devices are enhanced with improved operating frequency and lower power consumption. SST25VF080B-80-4I-S2AE 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 better reliability and manufacturability compared with alternate approaches.
The SST25VF080B-80-4I-S2AE devices significantly improve performance and reliability, while lowering power consumption. The devices write (Program or Erase) with a single power supply of 2.7-3.6V for SST25VF080B. The total energy consumed is a function of the applied voltage, current, and time of application. Since for any given voltage range, the SuperFlash technology uses less current to program and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash memory technologies.
The SST25VF080B-80-4I-S2AE device is offered in 8-lead SOIC (200 mils), 8-lead SOIC (150 mils), 8-contact WSON (6mm x 5mm), and 8-lead PDIP (300 mils) packages. See Figure 2 for pin assignments.
