Hot-selling and scarce SST25VF040B-50-4C-S2AF FLASH Memory IC 4Mbit SPI 50 MHz 8-SOIC spot stock

Product Descriptions

The 25 series Serial Flash family features a four-wire,SPI-compatible interface that allows for a low pin-countpackage which occupies less board space and ultimately lowers total system costs .The SST25VF040Bdevices are enhanced with improved operating frequency and even lower power consumption .SST25VF040B SPI serial Flash memories are manufactured with proprietary, high-performance CMOSSuperFlash®technology.The split-gate cell design andthick-oxide tunneling injector attain better reliability andmanufacturability compared with alternate approaches .

SST25VF040B devices significantly improve performance and reliability,while lowering power consumption .The devices write (Program or Erase)with a singlepower supply of 2 .7V-3 .6V for SST25VF040B .The totalenergy consumed is a function of the applied voltage,current,and time of application .Since for any givenvoltage range,the SuperFlash technology uses lesscurrent to program and has a shorter erase time,thetotal energy consumed during any erase or programoperation is less than alternative Flash memory technologies .
