产品描述：
The 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 SST25VF040B devices are enhanced with improved operating frequency and even lower power consumption.SST25VF040B SPI serial flash memories are manufactured 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 consumption. 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 technologies. 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.
