New FRAM solution for automotive applications from Fujitsu

Non-volatile memory technology with extended temperature range (Compliant with AEC Q100)

Fujitsu Electronics Europe has launched its new FRAM (ferroelectric RAM) solution MB85RS256TY. It is the first component of a completely new product group which is designed for an operating temperature of up to 125°C and is qualified according to the AEC Q100 industry standard, making it particularly suitable for use in the automotive sector. With the new series, Fujitsu wants to serve various applications in the automotive market and support innovative projects.

The ever increasing demand from the automotive industry for electronic control systems, which access a wide variety of sensor data, has led to a growing demand for high-performance non-volatile memory technology. Only in this way can data collected by sensors be reliably stored without a delay – for example, for analysis purposes or for other forms of data processing. 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.

MB85RS256TY incorporates 256kbit FRAM memory density, SPI serial interface and an extended operating voltage range of 1.8 to 3.6V. The operating temperature of this device ranges from -40°C to +125°C. This extended temperature range meets the standard requests from the automotive market as well as industrial applications within hot environments. MB85RS256TY is housed in a standard SOP-8 package.
Also was announced a second high temperature 128kbit FRAM MB85RS128TY.

“The automotive industry is undergoing the biggest transformation in its history”, says Dr. Klaus-Peter Dyck, senior manager marketing & application at Fujitsu Electronics Europe. “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”.

Fujitsu has been offering FRAM technology to the market since 1999. As a non-volatile memory technology, FRAM offers unique advantages of fast random access, high read and write endurance (it guarantees 10 trillion read/write cycles across its full temperature range) and low power consumption. These features enable direct and reliable storage of logging data without any delay and simplify the system architecture on the customer side. FRAM technology has been widely adopted in various industrial applications. With the new high temperature portfolio, Fujitsu is aiming to serve new markets such as the automotive sector and industrial automation.

With the new MB85RS128TY, Fujitsu responds to customer requests for a FRAM with lower storage density. This goes in line with Fujitsu’s approach to offer tailor-made solutions that flexibly fit its customers’ individual needs.

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