Fujitsu has positioned its new non-volatile FRAM (Ferroelectric Random-Access Memory) devices to meet the automotive requirements.
Fujitus says that its new FRAM chip (MB85RS256TY) covers the entire automotive temperature range up to 125°C and down to -40°C. The 256 kilobit device is guaranteed to retain its data content for ten years or even longer, even under worst-case conditions of 85°C constantly.
High-performance non-volatile memory is used for electronic control systems accessing multiple and various sensor types. Only with such memory types as FRAM, the sensor data can be stored without any delay and reliably. FRAM is the technology of choice when fast access is equally required as the capability for frequent writing - something where both EEPROMs and NOR Flash hits its limits. 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.
The MB85RS256TY comes with an SPI interface and operates under an extended voltage range from 1.8 to 3.6V. Fujitsu specifies the chip for 10 13 write cycles, far more than components with comparable density in EEPROM and Flash technology.
Fujitsu said that the automotive qualification according to AEC-Q100 will be completed by July 2017.
