The GD32H737xx devices belong to the high-performance series of the GD32 MCU family. They are new 32-bit general-purpose microcontrollers based on the Arm Cortex-M7 core, offering the best cost-performance ratio in enhanced processing power, reduced power consumption, and peripheral configuration. The Arm Cortex-M7 processor is a high-performance embedded processor featuring low interrupt latency, low-cost debugging, and compatibility with existing Cortex-M series processors. This processor employs an in-order superscalar pipeline, enabling dual-issue of many instructions, including load/load and load/store instruction pairs, thanks to its multiple memory interfaces. The Cortex-M7 is a high-performance processor with a 6-stage superscalar pipeline, branch prediction, and an optional floating-point unit (FPU) supporting single-precision operations, with optional support for double-precision operations. The instruction and data buses have been expanded from 32-bit to 64-bit. It also includes a Memory Protection Unit (MPU) and robust trace technology to enhance application security. The GD32H737xx devices integrate an Arm Cortex-M7 32-bit processor core operating at 600 MHz, with Flash security protection to prevent unauthorized code/data access. They provide up to 3840 KB of on-chip Flash memory, 512 KB AXI SRAM, and 512 KB shared (ITCM/DTCM/AXI) RAM. A wealth of enhanced I/Os and peripherals are connected to four APB buses. The devices feature up to two 14-bit 4 MSPS ADCs, one 12-bit 5.3 MSPS ADC, one 12-bit DAC, up to twelve general-purpose 16-bit timers, two 16-bit PWM advanced timers, four 32-bit general-purpose timers, and four 16-bit basic timers, as well as standard and advanced communication interfaces: up to six SPIs, two OSPIs, four I2Cs, four USARTs, four UARTs, four I2Ss, three CANs, two USBHSs, two ENETs, two SDIOs, and one MDIO. Additionally, they include peripherals such as a Digital Camera Interface (DCI), an EXMC interface supporting SDRAM expansion, a TFT-LCD interface (TLI), an Image Processing Accelerator (IPA), a Serial Audio Interface (SAI), a Sony/Philips Digital Interface Receiver (SPDIF), a Filtering Arithmetic Accelerator (FAC), Real-Time Decryption (RTDEC), and a High-Performance Digital Filter module (HPDF). The devices operate within a voltage range of 1.71V to 3.6V and a temperature range of -40°C to 85°C. Three power-saving modes offer flexible power optimization, which is particularly important for low-power applications. These features make the GD32H737xx devices suitable for a wide range of connected and advanced applications, especially in industrial control, consumer and handheld devices, embedded modules, human-machine interfaces, security alarm systems, energy storage systems, graphic displays, audio players, automotive navigation, drones, and the Internet of Things (IoT).
