Grade 1 automotive F-RAM memory devices from Ramtron

Ideal for advanced powertrain systems, the FM25040A-GA offers fast writes, virtually unlimited endurance, and low power. In stringent data collection applications, F-RAM enables rapid and frequent writes to prevent data loss and guarantee data integrity in noisy automotive environments.

The FM25040A-GA is a 4Kb nonvolatile RAM with an industry-standard SPI that leverages the high-speed write capability of F-RAM technology. This 4Kb F-RAM automotive device is a direct hardware replacement for equivalent EEPROMs but offers No Delay™ writes, much higher endurance, and lower operating currents. The FM25040A-GA reads and writes at bus speeds up to 14MHz, boasts a 10µA standby current, and includes an advanced write protection scheme to prevent inadvertent writes and data corruption. Operating at 5V over the automotive temperature range of -40ºC to +125ºC, the FM25040A-GA is guaranteed to retain data for 9,000 hours at +125ºC and 17 years at +55ºC degrees, and is available in a “green”/RoHS 8-pin SOIC package.
