MB85RS2MTA: Key Features of Industrial Grade FRAM Chip

Fujitsu's FRAM technology holds a leading position in the storage field with its superior performance and innovative features. FRAM technology is known for its ultra-high endurance of up to 100 trillion read/write cycles, fast write speed of 150 nanoseconds, extremely low power consumption (only 1/400 of EEPROM), and a wide operating temperature range (-40°C to +85°C, with some models reaching +125°C). These characteristics ensure stable operation in various environments, especially in applications such as smart meters, automotive electronics, industrial control, and medical devices.

FRAM supports a variety of interface options, including I2C, SPI, and parallel interfaces compatible with EEPROM and SRAM, enhancing its compatibility and applicability in different systems and devices. The non-volatile nature of FRAM ensures that data is not lost in the event of power failure, which is crucial for applications requiring highly reliable data storage. Fujitsu continues to drive technological innovation, such as the development of next-generation storage products like NRAM, to meet market demands for larger capacity and higher-performance memory, and with over 21 years of production experience, ensures the high quality and stable supply of FRAM products.

The MB85RS2MTA is a high-performance FRAM chip launched by Fujitsu, with a storage capacity of 262,144 words x 8 bits, that is, 2Mbit. This chip transfers data via the SPI interface, supports mode 0 and mode 3, and can operate at a maximum frequency of 40MHz. The read/write endurance of the storage cells in the MB85RS2MTA has been significantly improved, capable of reaching 10^13 cycles, far exceeding the read/write cycles of Flash memory and E2PROM. Its data retention time is very long, ranging from 10 years to over 200 years depending on temperature conditions. The operating supply voltage range is 1.8V to 3.6V, with a maximum operating supply current of 2.3mA at 40MHz, a maximum standby current of 50μA, and a maximum sleep current of 10μA, demonstrating its low-power characteristics. The MB85RS2MTA has a wide operating temperature range suitable for industrial-grade applications (-40°C to +85°C).

In the field of industrial automation, the MB85RS2MTA plays an important role. It ensures that critical operational parameters, fault records, and maintenance logs are never lost under any circumstances, which is essential for system reliability and fault diagnosis. The chip supports high-speed data updates, with no waiting time to complete writing, making it suitable for real-time monitoring and rapid data processing. The high read/write endurance and wide operating temperature range of the MB85RS2MTA enable it to operate stably in harsh industrial environments, while its low-power characteristics help extend the service life of battery-powered devices. In addition, the MB85RS2MTA is widely used in industrial control systems for logic control, motion control, and data acquisition, improving production efficiency and product quality. In summary, the MB85RS2MTA provides strong support for the reliability and efficiency of industrial automation systems with its excellent performance.
