Artery AT32 MCU Empowers Low-Altitude Economy, Driving UAV Technology Innovation

With the integration of low-altitude economy into the national strategic system, the drone industry is experiencing explosive growth. According to the "National Comprehensive Three-Dimensional Transportation Network Plan Outline," China's low-altitude economy is projected to exceed 6 trillion yuan by 2035. As the core carrier of the low-altitude economy, drone technology continues to evolve toward higher performance and reliability, while microcontrollers (MCUs), serving as the "brain" of drones, directly determine the performance limits of the entire system. The Artery AT32 series MCUs, with their high-performance computing capabilities, rich peripheral interfaces, and exceptional reliability, have become an ideal solution for core drone subsystems such as flight controllers, ESCs, and gimbals.

Drone Flight Controller: High-Performance Computing Enables Precision Control

The flight controller (FC) is the control center of a drone, requiring real-time processing of multi-channel sensor data and execution of complex control algorithms. The Artery AT32F435 series, equipped with an ARM® Cortex®-M4F core running at 288MHz, offers 4032KB Flash and 512KB SRAM, providing ample computing resources for open-source flight control algorithms (e.g., ArduPilot, PX4). Its double-precision FPU accelerates attitude resolution, while three SPI interfaces enable IMU redundancy design, enhancing system reliability. In practical applications, the AT32F435 can simultaneously process GPS positioning, obstacle avoidance sensing, and image transmission tasks, ensuring centimeter-level positioning accuracy for drones in scenarios such as logistics delivery and power inspection.

Electronic Speed Controller: High-Precision PWM Optimizes Power Efficiency

The electronic speed controller (ESC) directly impacts a drone's power response and energy efficiency. The AT32F421 series, with a 120MHz main frequency and 64KB Flash storage, supports 32-bit high-resolution PWM output and switching frequencies up to 100kHz, enabling precise motor torque control. Its built-in comparator completes overcurrent detection within 2μs, working with advanced timers to achieve sensorless FOC control, increasing drone power efficiency to over 92%. The chip's 4×4mm package significantly reduces the size of the ESC module, facilitating compact drone designs.

Gimbal Stabilization System: Professional-Grade Imaging Quality

For professional aerial photography needs, the AT32F423 series features a 150MHz Cortex-M4F core and a 5.33Msps 12-bit ADC, delivering robust computing power for three-axis gimbals. Its hardware trigonometric accelerator enables real-time quaternion attitude resolution, combined with an adaptive PID algorithm to achieve a gimbal stability accuracy of 0.01°. In dynamic shooting scenarios, the chip's DMA controller synchronously processes gyroscope data and motor drives, effectively suppressing high-frequency vibrations to meet cinematic-grade filming requirements.

Empowering Low-Altitude Economy Applications

In power inspection, drones equipped with Artery MCUs can autonomously complete 100km line inspections, achieving centimeter-level defect identification through precise positioning systems. In agricultural plant protection, the MCU intelligently plans spraying paths, increasing pesticide utilization to over 90%. Artery MCUs also ensure data security via hardware encryption modules, meeting the communication security needs of logistics drones in complex urban environments.

Technological Innovation Drives Industry Upgrades

The Artery AT32 series promotes drone technology innovation through chip-level advancements: the AT32F435's memory accelerator (with a 45% speedup ratio) significantly enhances real-time task responsiveness; the full series operates in an industrial-grade temperature range of -40°C to 105°C, ensuring reliability in extreme environments; and the unique sLib security library function protects core algorithm intellectual property. These features make Artery MCUs the preferred solution for leading companies like DJI and XAG.

As 5G networks and AI technologies converge, Artery will continue to optimize MCU architecture to provide computational support for advanced applications such as drone swarm formation and autonomous obstacle avoidance. In the future, Artery will leverage ongoing technological innovation to help the low-altitude economy achieve digital and intelligent transformation, contributing core power to the construction of a modern transportation system.
