Features & Applications
The FM25V05-GTR is a part of FM25V05 series 3.6 V, 512K-bit (64K x 8) Serial F-RAM Memory. It has an operating temperature ranging from -40°C to +85°C and its available in SOIC-8 surface mount package.

The FM25V05 is a 512-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. It provides reliable data retention for 10 years while eliminating the complexities, overhead, and system level reliability problems caused by Serial Flash and other nonvolatile memories.
