Fujitsu FRAM Paves the Way for a New Era of UAV Data Storage

In the fields, drones precisely spray pesticides; at rescue sites, they penetrate smoke to locate survivors; in surveying, they rapidly generate centimeter-level real-scene models. Drones are reshaping industries in unprecedented ways. Behind these breakthrough applications lies a stringent test of core hardware. Traditional solutions using EEPROM or Flash to store sensor data and flight logs are often limited by their slow write speeds (millisecond level) and finite endurance (around 100,000 write/erase cycles). When frequently recording flight attitudes, environmental parameters, and high-definition images, the latency of traditional storage can lead to critical data loss, while the high power consumption from rapid read/write operations can further shorten the valuable flight time.

The emergence of FRAM (Ferroelectric Random Access Memory) has provided a revolutionary solution for drones. Its unique ferroelectric crystal structure enables nanosecond-level high-speed writing, thousands of times faster than EEPROM, ensuring data safety even during sudden power loss. With 10 trillion read/write cycles of durability, FRAM eliminates concerns about device failure due to frequent writing. Its ultra-low power consumption (only 1/140 that of EEPROM) significantly reduces system energy consumption, making longer flight times possible. These features make FRAM an ideal choice for real-time flight control, high-frequency sensor recording, and black-box functions, providing drones with a more reliable "memory core."

Facing the real-time processing demands of massive drone data, high-capacity storage has become essential. The 4Mbit FRAM, with its balanced performance and density, plays a key role in the system. It can not only cache GNSS positioning information, gyroscope attitudes, and barometer readings at high speed to ensure real-time response of the flight control system, but also completely record mission waypoints, abnormal event logs, and sensor calibration parameters, providing a complete data chain for later analysis and troubleshooting. Compared to traditional solutions, the 4Mbit FRAM's ultra-high write bandwidth (up to 54MB/s under Quad SPI interface) can easily handle the temporary storage needs of 4K video transmission segments and multispectral images, avoiding frame loss due to storage delays. Its wide temperature range (-40℃ to +125℃) ensures stable operation in extreme environments such as high-altitude cold or desert heat. Abandoning the traditional battery data maintenance mechanism simplifies circuit design fundamentally and exponentially reduces failure rates in vibration environments. This storage solution, which combines speed, endurance, and adaptability, lays the hardware foundation for drones to achieve higher-level autonomous flight and complex mission execution.

The breakthrough 4Mbit storage unit MB85RS4MTY demonstrates Fujitsu's leading position in the ferroelectric storage field. This device features an advanced SPI interface (compatible with standard EEPROM pins), a working voltage range of 1.8V-3.6V, and supports a working frequency of up to 50MHz. Its core advantages include: an ultra-low operating current of only 4mA at 125℃, significantly reducing system thermal load; a read/write lifespan of 10 trillion cycles ensuring maintenance-free operation throughout its entire life cycle; and nanosecond-level write speed (a single data refresh can be completed in 0.03ms), perfectly matching high-speed data acquisition scenarios. For drones, this means the ability to continuously record motor speed and battery temperature at millisecond intervals for ten years, or to stably save critical navigation data in industrial areas with dense 5G/radar frequency coverage. Fujitsu's ferroelectric lattice structure achieves charge immunity, maintaining signal integrity even in flight systems covered by 5G/radar frequencies.
