The SST25VF040B devices are enhanced with improved operating fre- quency and even lower power consumption. SST25VF040B SPI serial flash memories are manu- factured with 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. SST25VF040B devices significantly improve perfor- mance and reliability, while lowering power consump- tion. The devices write (Program or Erase) with a single power supply of 2.7-3.6V for SST25VF040B. 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 technol- ogies. The SST25VF040B device is offered in an 8-lead SOIC (200 mils), 8-lead SOIC (150 mils), and 8-contact WSON (6mm x 5mm) packages. See Figure 2-1 for pin assignments.
