Description
General part information
FM25W256 Series
The FM25W256-GTR is a high-speed 256 Kbit F-RAM with 151-year data retention, rapid bus-speed write operations, and substantial write endurance, making it ideal for reliable nonvolatile memory applications. It outperforms traditional serial flash and EEPROM, offering efficient and reliable performance across a wide industrial temperature range from -40 °C to +85 °C. Its guaranteed specifications and high-speed SPI bus compatibility make it suitable for critical applications supporting 1014read/write cycles, or 100 million times more write cycles than EEPROM.
