Description：

The GigaDevice GD32F425VGT6 is a well-balanced, high-performance microcontroller within the GD32F4 series. It leverages a powerful 200 MHz Arm® Cortex®-M4 core with FPU and is housed in a versatile 100-pin LQFP package. A key feature of this model is its enhanced 1024KB (1MB) Flash memory, paired with the series' integrated TFT LCD controller and hardware graphics accelerator (IPA). This combination makes it an excellent choice for embedded systems that require a substantial amount of code space for graphical user interfaces, moderate real-time control tasks, and rich connectivity, such as industrial human-machine interfaces (HMI), advanced motor control panels, and networked power management units.

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.

Dedicated Graphics Acceleration: Built-in IPA (Image Processing Accelerator) hardware graphics accelerator, significantly optimizing 2D graphics processing efficiency.

2. Advanced Peripherals & Interfaces

Core Graphics Display: Integrated TFT LCD controller, capable of directly driving RGB interface LCD screens, forming the foundation for building interactive interfaces.

Comprehensive Connectivity: Provides USB 2.0 OTG FS, CAN 2.0B, Ethernet MAC (EMAC), and multiple USART, I2C, SPI interfaces (specific availability requires verification with the 100-pin package pinout diagram).

Multimedia & Vision: Built-in hardware JPEG codec and supports Digital Camera Interface (DCI).

High-Speed Analog: Features 3 channels of 12-bit ADC (up to 2.6 MSPS) and 2 channels of 12-bit DAC.

3. Memory, Package & Reliability

Large-Capacity Memory Configuration (Key Differentiator): The "G" in the model number represents that it is equipped with 1024KB (1MB) Flash and 128KB SRAM. This provides more ample space for complex GUIs, network protocol stacks, and business logic compared to 512KB models.

General-Purpose Package: The "V" in the model number represents a 100-pin LQFP package. This package achieves a good balance between I/O count, PCB design difficulty, and soldering processes, making it one of the most versatile and popular package choices.

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

Typical Applications：

The combination of "1MB Storage + Rich Peripherals + User-Friendly Package" makes it an ideal platform for general-purpose high-performance applications:

Full-Featured Industrial Human-Machine Interfaces: Industrial touchscreens with complex graphics and network functions, smart device control panels.

Intelligent Motor Drive & Control: Human-machine interaction modules for frequency converters and servo drives that integrate displays and advanced algorithms.

Networked Energy Equipment: Display and control units for photovoltaic monitoring systems, charging piles, smart meters.

Medical & Commercial Equipment: Displays for portable medical devices, self-service terminals, interactive digital signage.
