Description：

The GigaDevice GD32F427VKH6 represents the pinnacle of memory capacity within the GD32F4 series. It leverages the high-performance 200 MHz Arm® Cortex®-M4 core with FPU and pairs it with the series' maximum embedded Flash memory of 3072KB (3MB), all housed in a 100-pin LQFP package. This combination, along with its integrated TFT LCD controller and hardware graphics accelerator (IPA), makes it the ultimate single-chip solution for the most demanding embedded applications that require extensive code space for complex graphical user interfaces, full-featured communication protocol stacks, and sophisticated data processing algorithms.

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 instructions.

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

2. Advanced Peripherals & Interfaces

Advanced Display Support: Integrated TFT LCD controller, capable of directly driving RGB interface LCD screens.

Rich Connectivity: Provides 10/100M Ethernet MAC, USB 2.0 OTG HS (High-Speed), dual CAN 2.0B, as well as up to 8 serial ports (4 USART + 4 UART), 3 I2Cs, and 6 SPIs.

Multimedia & Camera Interface: Built-in hardware JPEG codec and supports 8~14-bit parallel Digital Camera Interface (DCI).

High-Speed Analog: Features 3 channels of 12-bit ADC (with sampling rate 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 256KB SRAM in the GD32F4 series. This provides ample space for running Linux-like RTOS, complex GUI libraries (e.g., LVGL), file systems, network protocol stacks (e.g., LWIP), and a large amount of application logic.

Package: "V" represents the 100-pin LQFP package, offering balanced I/O capability.

Industrial-Grade Reliability: The suffix "H6" indicates an operating temperature range of -40°C to +85°C.

Typical Applications：

The combination of its ultra-large Flash memory and high-performance graphics processing enables it to handle extremely complex systems with massive codebases:

High-End Industrial HMI & Control Systems: Industrial all-in-one machines running complex UIs and logic, high-end PLC main control units, CNC system human-machine interfaces.

Multifunctional IoT Gateways / Edge Computing Nodes: Intelligent gateways that require simultaneous operation of multiple Ethernet/CAN protocols, MQTT/Modbus stacks, local databases, and edge AI models.

Advanced Audio-Video & Recognition Devices: Face recognition access control terminals, interactive digital signage, video conferencing terminals, smart retail terminals.

Complex Consumer Electronics: Feature-rich smart home control screens, main controllers for advanced educational/entertainment robots.
