Product Summary

The FM24L256-G is a 256-kilobit nonvolatile memory employing an advanced ferroelectric process. A ferroelectric random access memory or F-RAM is nonvolatile and performs reads and writes like a RAM. The FM24L256-G provides reliable data retention for 45 years while eliminating the complexities, overhead, and system level reliability problems caused by EEPROM and other nonvolatile memories. The FM24L256-G provides substantial benefits to users of serial EEPROM, yet these benefits are available in a hardware drop-in replacement. The device is available in industry standard 8-pin SOIC package using a familiar two-wire protocol.
