The FM25W256-G is a 256-Kbit (32K × 8) serial F-RAM with an SPI interface, offering 100 trillion (1014) read/write cycles and 151-year data retention at 65°C. Operating from 2.7 V to 5.5 V with up to 20 MHz clock, it features NoDelay writes at bus speed, advanced write protection, and low active current (250 μA at 1 MHz). Housed in an 8-pin SOIC for –40°C to +85°C, it is ideal for frequent-write, nonvolatile memory in industrial and mission-critical systems.
