256 Kbit FRAM with SPI interface operates up to temp of up to 125C

Date: 11/06/2017
Fujitsu announced its new FRAM chips MB85RS128TY and MB85RS256TY to withstand operating temperature of up to 125C and is qualified according to the AEC Q100 industry standard, making them usable for automotive electronics.

FRAM enables data collection by sensors reliably stored without a delay. FRAM (ferroelectric RAM) is non-volatile like flash memory but provides high-speed random access and has high write endurance. FRAM reduces system complexity and increases data integrity by allowing instant and continuous data storage in applications such as air bag data storage, event data recorders (EDR), battery management systems (BMS), automatic driving assistance systems (ADAS) or navigation and infotainment systems.

The new automotive FRAM products MB85RS128TY and MB85RS256TY offer a 256kbit FRAM with SPI interface and an extended operating voltage range of 1.8 to 3.6V. The operating temperature of this device ranges from -40C to +125C. This extended temperature range meets the standard requests from the automotive market as well as industrial applications within hot environments. MB85RS128TY and MB85RS256TY offer a write endurance of 1013 and is housed in a standard SOP-8 package.

"The automotive industry is undergoing the biggest transformation in its history", says Jim Feng, director of product management department at Fujitsu Electronics,. "With products such as our new FRAM solution we support innovative companies, enabling them to make their ideas a reality. We act as a gateway for components from all around the world while providing expert consultancy throughout each project. In this way, we find a solution for every challenge and accelerate our clients? innovation process."

MB85RS128TY and MB85RS256TY are available now in samples. AEC Q100 qualifications are scheduled to be completed in July 2017.
