Ferroelectric RAM joins automotive club
Ideal for advanced powertrain systems, the FM25040A-GA offers fast writes, virtually unlimited endurance and low power
Ramtron has added another 4Kbit ferroelectric RAM device to its Grade 1 AEC-Q100-qualified automotive product line, growing its number of +125C parts to five. The FM25040A-GA - a 4Kbit 5V FRAM with a high-speed serial peripheral interface (SPI) - is now specified to operate at +125C and is guaranteed to retain data for 9kh at that extreme temperature.

Ideal for advanced powertrain systems, the FM25040A-GA offers fast writes, virtually unlimited endurance and low power.
In stringent data collection applications, FRAM enables rapid and frequent writes to prevent data loss and guarantee data integrity in noisy automotive environments.
The 4Kbit FRAM 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 10uA 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 -40 to +125C, the FM25040A-GA is guaranteed to retain data for 9kh at +125C and 17 years at +55C, and is available in a 'green'/RoHS 8-pin SOIC package. Request a free brochure from Ramtron International....
