Ramtron has unveiled the new, advanced FM25L04-GA serial peripheral interface (SPI), which is now Grade 1 AEC-Q100-specified to operate over the automotive temperature range of -40 Celsius to +125 Celsius. The device can retain data for 9,000 hours even in these extreme temperatures, claims the company.
The FM25L04-GA is designed specifically for advanced powertrain systems where F-RAM is required to record data quickly and frequently so that the gearbox can continually adapt itself to changing driver behaviour and road conditions. The 4-kilobit, 3-volt device's F-RAM No Delay writes and virtually unlimited endurance, coupled with a high-speed SPI interface, enables reliable data writes at maximum bus speed in a range of other automotive applications as well.
The device is a direct hardware replacement for equivalent electrically erasable programmable read-only memory (EEPROM) devices, but is more advanced due to its fast writes, endurance capability and low operating currents. The FM25L04-GA reads and writes at bus speeds up to 10MHz and features an advanced write protection scheme to prevent inadvertent writes and data corruption.
Headquartered in Colorado, Ramtron International Corporation designs, develops and markets specialised microcontrollers and integrated semiconductor software and chips for automotive and industrial applications.
