Fujitsu starts mass-production of 4Mbit FRAM with 125 degrees C operation conforming to automotive grade

Fujitsu Semiconductor Memory Solution Limited announced on July 6, the start of mass-production of 4Mbit FRAM MB85RS4MTY, which guarantees operation up to 125 degrees C.

FRAM is a non-volatile memory product with superior features of high read/write endurance, fast writing speed and low power consumption, and it has been mass-produced for over 20 years.

Since mass-production of FRAM products capable to operate up to 125 degrees C started in July 2017, its product lineup has been expanding. This time the 4Mbit FRAM MB85RS4MTY, which has the largest density in the 125 degrees C -operating FRAM product family, is added to mass-production this month.

The MB85RS4MTY meets high-reliability testing to satisfy AEC-Q100 Grade 1, a qualification requirement for products as “automotive grade,” therefore suitable for high-performance industrial robots and automotive applications such as advanced driver-assistance systems (ADAS’s) that require high reliability in high-temperature environments.

This FRAM with an SPI interface operates at a wide power supply voltage from 1.8V to 3.6V. In the temperature range from -40 to +125 degrees C, it guarantees 10 trillion read/write cycle times and low operating current such as a maximum write current of 4mA (operated at 50MHz). It is housed in an 8-pin DFN (Dual Flatpack No-leaded) package.

The FRAM products can solve issues arising from using EEPROM or SRAM for high-reliability applications and bring to customers benefits like reduced development burden, enhanced customer product performance, and lower costs.

Fujitsu Semiconductor Memory Solution Limited continues to develop memory products to satisfy the needs and requirements from the market and customers.
