Description：

The GigaDevice GD32F425VKT6 represents the pinnacle of memory capacity within the GD32F4 series for the highly versatile 100-pin LQFP package. It combines the robust 200 MHz Arm® Cortex®-M4 core with FPU, the series' essential TFT LCD controller and hardware graphics accelerator (IPA), and the maximum available 3072KB (3MB) Flash memory. This configuration delivers an unparalleled balance of processing power, advanced graphical capabilities, and massive code/data storage, making it the ultimate single-chip solution for the most demanding embedded applications that require complex graphical user interfaces, extensive network communication stacks, and sophisticated data processing, such as high-end industrial HMIs, feature-rich IoT gateways, and advanced digital control systems.

Main Features：

1. Core & Performance

Top-Tier Core Performance: 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, specifically optimized for 2D graphics processing to ensure smooth UI experience.

2. Advanced Peripherals & Interfaces

Advanced Display Support: Integrated TFT LCD controller, capable of directly driving RGB interface LCD screens, forming the cornerstone for building complex graphical interfaces.

Comprehensive High-Speed 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

Maximum Memory Configuration (Key Differentiator): The "K" in the model number is the core identifier, representing that this model is equipped with the largest 3072KB (3MB) Flash and 128KB SRAM in the GD32F4 series. This provides vast space for running operating systems like embedded Linux, complex GUI frameworks (e.g., LVGL, emWin), large font and image resources, and historical data logs.

Optimal General-Purpose Package: The "V" in the model number represents a 100-pin LQFP package. This package provides rich I/O while significantly reducing the cost and risk of PCB design, soldering debugging, and mass production, making it an ideal physical carrier for developing complex systems.

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

Typical Applications：

The triple combination of "3MB Massive Storage + High-Performance Graphics + Easy-Development Package" makes it one of the ultimate hardware choices for developing top-tier complex systems:

High-End Industrial Human-Machine Interfaces & Controllers: Industrial tablets running lightweight operating systems (e.g., RT-Thread) and complex UIs, high-end PLC main controls, smart factory monitoring terminals.

Multifunctional IoT & Edge Computing Gateways: Intelligent industrial gateways that need to locally run complete TCP/IP protocol stacks, databases, edge AI models, and multi-protocol conversion.

Advanced Digital Power & Drive Systems: Core controllers for photovoltaic energy storage inverters and servo drives that implement complex algorithms, online upgrades (OTA), and extensive parameter logging.

Data-Intensive Consumer Devices: High-end smart home control screens, commercial interactive information release terminals, digital signage.
