SST25VF032B-66-4I-S2AF Microchip

Obsolete Device Please contact Microchip Sales for replacement information. 32 Mbit SPI Serial Flash SST25VF032B EOL Data Sheet SST 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 SST25VF032B devices are enhanced with improved operating frequency which lowers power consumption. SST25VF032B SPI serial flash memories are manufactured with SST s propri- etary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain better reliability and manufactur- ability compared with alternate approaches.

SST25VF032B SPI serial flash memories are manufactured with SSTs proprietary, high-performance CMOS SuperFlash technology. The split-gate cell design and thick-oxide tunneling injector attain bet- ter reliability and manufacturability compared with alternate approaches. The SST25VF032B 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 SST25VF032B. 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 pro- gram and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash memory technologies. The SST25VF032B device is offered in 8-lead SOIC (200 mils) and 8-contact WSON packages. See Figure 2 for pin assignments. 2015 DS20005071B 04/15 2
