High-Reliability Non-Volatile Memory Solutions for UAV Flight Control Systems
FRAM (Ferroelectric Random Access Memory) is the premier non-volatile memory solution for drone flight controllers (FCs) across consumer, industrial and commercial UAV applications. Flight controllers require robust storage for real-time sensor data, flight parameters, mission plans and critical crash records in dynamic aerial environments with extreme temperature fluctuations, vibration and potential power loss.
Unlike traditional flash memory or EEPROM, Smart Memories FRAM offers instant write capability (no data saving latency), unlimited read/write cycles (up to 10¹⁴ cycles) and ultra-low power consumption. It eliminates the risk of data loss during sudden battery failure or crash events, while its high endurance supports continuous high-frequency logging of flight data (up to 1kHz sampling rate) without memory degradation. This makes FRAM the ideal memory choice for drone flight controllers that demand reliable performance in mission-critical aerial operations.
Stores high-frequency IMU (Inertial Measurement Unit) data, GPS coordinates, altitude, speed and attitude parameters. Instant write speed ensures no data loss during rapid flight maneuvers, while ultra-low power consumption maximizes drone flight time by minimizing memory power draw.
Captures pre-crash flight data, error codes and sensor anomalies even during sudden power loss or hard impacts. FRAM's non-volatile nature requires no backup power to preserve critical crash data, enabling post-incident analysis and flight controller debugging.
Stores waypoint coordinates, flight modes, motor calibration parameters and sensor calibration data. Unlimited read/write cycles support frequent mission plan updates and calibration adjustments without memory wear, while wide temperature tolerance (-40°C to 85°C) ensures stability in extreme climates.
Retains PID tuning values, ESC settings, communication protocols and fail-safe parameters. FRAM's fast read/write performance enables real-time configuration adjustments during flight, and its vibration resistance prevents data corruption in high-vibration drone environments.
Note: Annual Output is 2025 estimated value (Unit: 10,000 sets). FRAM application focuses on core flight control scenarios with high reliability (data non-volatile after power-off).
