Fujitsu rolls 2nd generation of automotive FRAMs

May 11, 2017 // By Christoph Hammerschmidt
Having launched the first generation of automotive-rated Ferroelectric Random Access Memory (FRAM) chips as recently as last February, Fujitsu Electronics Europe is now rolling out the second generation of these non-volatile memory products. With the new MB85RS128TY, Fujitsu responds to customer requests for a FRAM with lower storage density. This goes in line with the company’s approach to offer tailor-made solutions that flexibly fit customers’ individual needs.

The MB85RS128TY has a capacity of 128 kbit and operates in the entire temperature range from -40°C to 125°C. It is qualified for automotive use according to the AEC Q100 standard, but Fujitsu intends to market it also in industrial markets where similar requirements exist. The new product incorporates a SPI serial interface with a maximum operating frequency of 33MHz and an extended operating voltage range of 1.8V to 3.6V. As a non-volatile memory, it guarantees 10 trillion read/write cycles across its full temperature range, far more than Flash memories.

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 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.

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