Features & Applications
The FM28V020-SGTR is a part of FM28V series 3 V, 256 K-bit (32K x 8) Parallel F-RAM Memory. It has an operating temperature ranging from -40°C to +85°C and its available in SOIC-28 surface mount package.

The FM28V020 is a 32K x 8 nonvolatile memory that reads and writes like a standard SRAM. A ferroelectric random access memory or F-RAM is nonvolatile, which means that data is retained after power is removed.
