With the rising demand for high-performance non-volatile memory technologies in the automotive electronic control systems, Fujitsu has announced the first FRAM device which claims to withstand operating temperatures of up to 125°C and is qualified according to the AEC Q100 industry standard, to suit automotive requirements.
Applications include data monitoring and analysis applications in cars such as airbag data storage, data event recorders (DER), battery management systems (BMS), advanced driver assistance systems (ADAS) as well as navigation and infotainment systems.
Automotive electronic control systems access multiple and various sensor types, and need to frequently store and access the sensor data without any delay and reliably. FRAM is considered an ideal and better memory type (compared to EEPROMs and NOR Flash) for these applications.
The new 256 kb FRAM, called MB85RS256TY, covers the automotive temperature range of -40°C up to 125°C.
“The chip supports 10 13 write cycles, making it better than EEPROM and Flash memories with comparable densities.”
The FRAM features an SPI interface. It operates under an extended voltage range from 1.8 to 3.6V. It is offered in a standard SOP-8 package.
The firm has made available development samples of the chip and plans to complete automotive qualification according to AEC-Q100 by July 2017.
