Description：

The GigaDevice GD32E517VET6 is an enhanced variant of the GD32E5 series, specifically engineered for demanding motor control and digital power applications that require greater code and data storage. Built around a robust 200 MHz Arm® Cortex®-M4 core with floating-point unit (FPU), this microcontroller integrates specialized peripherals for precise real-time control within a 100-pin LQFP package. The key differentiator is its increased 512KB Flash memory, making it ideal for complex servo drives, sophisticated industrial inverters, and advanced digital power systems where algorithm complexity and feature integration demand more substantial program space.

Main Features：

1. Core & Performance

High-Performance Core: 200 MHz Arm® Cortex®-M4 core, integrated with Single-Precision Floating-Point Unit (FPU) and supporting DSP instruction set, providing powerful computing capability for complex control algorithms (e.g., observers, parameter identification).

Dedicated Math Accelerator: Built-in hardware Trigonometric Mathematics Unit (TMU), significantly enhancing the computational efficiency of coordinate transformations in motor vector control (FOC).

2. Advanced Control & Peripherals

High-Precision Timers: Equipped with advanced timers, supporting high-resolution PWM generation and dead-time management, which are core to achieving precise motor commutation and efficient power conversion.

High-Speed Analog Front-End:

Multiple high-speed 12-bit ADCs, supporting simultaneous sampling to meet high-precision real-time acquisition of multi-phase currents and voltages.

Integrated high-speed comparators (CMP), providing nanosecond-level response hardware protection (e.g., overcurrent, overvoltage).

Rich Communication Interfaces: Provides CAN-FD (suitable for high-speed fieldbuses), UART, SPI, I2C, etc., facilitating the construction of networked, multi-axis coordinated control systems.

3. Memory, Package & Reliability

Enhanced Memory Configuration (Key Differentiator): The "E" suffix in the model number indicates it is equipped with 512KB Flash and 128KB SRAM. This doubles the capacity compared to the "C" suffix model (256KB), providing ample space for integrating more advanced algorithms (e.g., notch filters, vibration suppression), state machines, communication protocol stacks, and debugging logs.

Package: The "V" represents a 100-pin LQFP package, offering good I/O expansion capability, heat dissipation, and production-friendly characteristics.

Industrial-Grade Reliability: The suffix "T6" indicates an operating temperature range of -40°C to +85°C.

Typical Applications：

Its enhanced storage capability enables it to handle more complex software architectures and algorithms:

High-End High-Performance Motor Drives: Servo drives with full-state feedback and advanced algorithms (e.g., parameter self-tuning, adaptive control), robot multi-axis controllers.

Complex Digital Power Systems: High-performance server power supplies, photovoltaic optimizers employing complex modulation strategies and multi-loop control.

Industrial Automation Main Control: Compact PLCs, intelligent IO controllers integrating motion control and logic processing functions.
