Fujitsu FRAM Assists in Efficient and Reliable Data Management for Medical Devices.

In the development of intelligent medical equipment, from portable health monitoring devices and implantable medical devices to large-scale medical imaging systems, various types of equipment have diverse requirements for the real-time, reliable, and low-power characteristics of data storage. Traditional storage solutions, such as EEPROM or Flash, face bottlenecks in frequent read/write scenarios, including slow write speeds, high power consumption, and limited erase/write cycles, making it difficult to meet the requirements of medical devices for precise data processing. FRAM (Ferroelectric Random Access Memory), with its unique ferroelectric crystal polarization storage mechanism, combines the high-speed random read/write capabilities of RAM with non-volatile storage characteristics. It can achieve microsecond-level data read/write without pre-erase operations, and its erase/write life exceeds 10¹⁴ cycles, fundamentally solving the pain points of traditional storage technologies and becoming a key breakthrough in the hardware design of medical devices.

In medical device applications, the core value of FRAM lies in the optimization of data management across all scenarios. For wearable medical devices such as smart blood pressure monitors and dynamic electrocardiographs, its ultra-low power consumption (with standby current as low as the nanoampere level) can significantly extend battery life, and its high-speed read/write capabilities ensure real-time storage of physiological data without delay. In implantable devices such as pacemakers, the non-volatile storage of FRAM eliminates the need for battery backup, avoiding data loss risks. Its anti-electromagnetic interference capability and wide temperature adaptability (-40°C to 85°C) ensure stable operation in complex in vivo environments. For medical information devices, the real-time data synchronization advantages of FRAM enable efficient storage of calibration parameters for inspection equipment and operation logs for surgical robots, facilitating intelligent transformation.

As a dedicated solution for medical devices, the Fujitsu MB85RS64VY FRAM chip integrates a 64Kb storage unit and uses an I²C communication interface, supporting a voltage range of 1.8V to 3.6V to meet the power design requirements of different devices. The chip supports standard read/write speeds of 100kHz and fast mode speeds of 400kHz, while maintaining low current characteristics of 500μA in active state and 5μA in standby state. This ensures the smoothness of real-time data processing while effectively reducing the overall power consumption of the device. The chip's compact 8-pin SOIC packaging enables seamless integration into portable devices and, with more than 10¹⁴ erase/write cycles and a 10-year data retention capability, lays a solid storage foundation for the long-term reliable operation of medical devices.

In medical device applications, the industrial-grade temperature range of the MB85RS64VY ensures stable operation in extreme environments such as high temperatures in operating rooms and low temperatures in cold chain equipment. The hardware write protection function locks key data areas through the WP pin, providing a security barrier for patient information and device parameters. As an authorized agent of Fujitsu, MANDU offers professional support for selection, technical consultation, and sample services, assisting R&D teams in quickly evaluating chip performance, optimizing hardware design solutions, and shortening product development cycles. Whether it is the low-power design of portable devices or the high-reliability requirements of implantable devices, the MB85RS64VY can meet the core needs of medical scenarios through its technical advantages.

As medical devices develop towards precision and portability, high-performance storage solutions have become an important cornerstone for technological upgrades. The Fujitsu MB85RS64VY FRAM chip, with its high-speed read/write capabilities (100kHz in standard mode / 400kHz in fast mode), ultra-low power consumption (only 5μA in standby), long life (over 10¹⁴ erase/write cycles), and wide temperature adaptability (-40°C to 85°C), fully empowers the data acquisition, storage, and intelligent management of medical devices. MANDU's full-process support services further reduce the barriers to technological implementation. For R&D engineers, choosing Fujitsu FRAM is not only an enhancement of storage performance but also a dual guarantee for the long-term stable operation and data security of medical devices.
