Fujitsu Semiconductor Memory Solution Limited
Fujitsu has Launched a 2Mbit FeRAM with a 1.8V Power Supply and a Guaranteed Operation up to 125℃
Non-volatile memory optimal for advanced driver-assistance systems (ADAS) for advanced automotive market
Yokohama, Japan, April 14, 2020 – Fujitsu Semiconductor Memory Solution Limited today announced a launch of MB85RS2MLY, a new 2Mbit FeRAM* guaranteed to operate up to 125℃. This product has a low power supply voltage range from 1.7V to 1.95V and a serial peripheral interface (SPI). Evaluation samples are currently available, while mass-production is expected by coming June.
This new FeRAM product is optimal for electronic control units which require low-power operating electronics components in advanced automotive markets such as ADAS.
FeRAM is a non-volatile memory product with features of higher read/write endurance, faster writing speed operation and lower power consumption compared to EEPROM and flash memory. FeRAM has been adopted by customers who are not satisfied with the specifications of conventional non-volatile memories.
Since 2017, Fujitsu has been providing 64Kbit to 2Mbit automotive grade FeRAM products that operate up to 125℃ on 3.3V or 5V power supply. However, some customers have been requesting for FeRAM that can operate at lower voltage than 1.8V like 1.7V, especially for electronic control unites of advanced automobiles that need electronics components with lower power consumption. We are pleased to be able to fulfill this requirement with our new 2Mbit FeRAM product.
The MB85RS2MLY guarantees 10 trillion read/write cycle times in the temperature range from -40°C to +125°C. This characteristic is optimal for some applications that require real-time data logging.
For instance, if data is recorded at every 0.1 seconds every day for 10 years, number of write times is more than 3 billion. In addition, the reliability testing for this product is compliant to AEC-Q100 Grade 1, a qualification requirement for a product to be called "automotive grade." Therefore, our new FeRAM is guaranteed to be adopted for applications such as ADAS requiring real-time data logging, from viewpoints of both data write endurance and reliability.
This FeRAM product is housed in an industry-standard 8-pin SOP package, making it easy to replace existing EEPROM that has a similar footprint. In addition, 8-pin DFN (Dual Flatpack No-leaded) package with the dimensions of 5.0 x 6.0 x 0.9mm is also available.
In addition to 2Mbit FeRAM, development of 4Mbit-density products in 125°C-operating family is ongoing.
Fujitsu Semiconductor Memory Solution Limited will continue to supply memory products and solutions to satisfy future needs and requirements from market and customers.

Glossary and Notes
- * FeRAM:Ferroelectric Random Access Memory
Ferroelectric random-access memory. A type of memory that uses a ferroelectric file as capacitors that store data. Retains contents even when power is removed. Combines benefits of both ROM and RAM, with fast write speed, low-power consumption, and high read/write cycle endurance. Produced by Fujitsu Semiconductor Memory Solution since 1999.
