Grade 1 automotive F-RAM memory devices from Ramtron
Ramtron International has added another 4 kilobit (Kb) F-RAM memory device to its Grade 1 AEC-Q100-qualified automotive product line, growing its number of +125ºC parts to five. The FM25040A-GA – a 4Kb, 5V F-RAM with a high-speed serial peripheral interface (SPI) – is now specified to operate at +125ºC and is guaranteed to retain data for 9,000 hours at that extreme temperature.Idea
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.
