SST25VF032B

Product Summary

The SST25VF032B is a 32 Mbit SPI Serial Flash. The SST25VF032B 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 significantly improves performance and reliability, while lowering power consumption. The SST25VF032B is offered in 8-lead SOIC (200 mils) and 8-contact WSON packages.
