Product Summary
The FM25640-GA is a 64-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or FRAM is nonvolatile but operates in other respects as a RAM. The FM25640-GA provides reliable data retention for years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM25640-GA provides substantial benefits to users of serial EEPROM, in a hardware drop-in replacement. The device uses the high-speed SPI bus, which enhances the high-speed write capability of FRAM technology.
