Description：

The GigaDevice GD32G553RCT7 is a robust and versatile member of the high-performance GD32G5 series. Built around a powerful 216 MHz Arm® Cortex®-M33 core, this microcontroller is engineered for the most demanding industrial real-time control and digital signal processing applications. Housed in a 144-pin LQFP package, it distinguishes itself by providing an extensive array of I/O pins and peripheral interfaces. This makes it an ideal solution for complex systems requiring multiple parallel connections, high-precision control, and extensive communication, such as advanced industrial automation platforms, multi-axis motor drives, and high-power digital power supplies.

Main Features：

1. Core & Performance

High-Performance Core: 216 MHz Arm® Cortex®-M33 core with DSP instruction set support and an integrated Single-Precision Floating-Point Unit (FPU).

Dedicated Hardware Accelerators: Built-in Trigonometric Mathematics Unit (TMU) and Filter Algorithm Accelerator (FAC), significantly enhancing the computational efficiency for control loops, signal processing, and digital filtering.

2. Advanced Control & Peripherals

High-Resolution Timer (HRTIM): Provides PWM output with a resolution as high as 145 picoseconds (ps), which is core to advanced digital power supply topologies and precision motor Field-Oriented Control (FOC).

High-Speed Analog Front-End: Integrates up to 4 channels of 12-bit high-speed ADC (max. 5.3 MSPS) and multiple 12-bit DACs, along with high-speed comparators (CMP), meeting the real-time signal processing needs for multi-channel, high dynamic range applications.

Rich Connectivity & Communication Interfaces:

The key advantage of the "R" package (144-pin LQFP) is the provision of an extremely high number of GPIOs, enabling simultaneous connection and control of more external devices and sensors.

Offers comprehensive communication interfaces including CAN-FD, multiple SPI/I2C/USART, Ethernet MAC (EMAC), and USB 2.0 FS/HS.

Enhanced Security: Equipped with hardware AES-128/256 encryption engine, Hash (HASH) processor, and True Random Number Generator (TRNG), supporting secure boot and secure communication.

3. Memory, Package & Reliability

Memory Configuration: According to model naming convention, the "C" suffix typically corresponds to 256KB Flash and 128KB SRAM (including 32KB Tightly Coupled Memory).

High-Pin-Count Package: The "R" in the model number indicates it uses a 144-pin Low-Profile Quad Flat Package (LQFP), one of the packages with the highest pin count and strongest I/O expansion capability in the series.

Industrial-Grade Reliability: The suffix "T7" indicates an operating temperature range of -40°C to +105°C, meeting stringent industrial environment requirements.

System-Level Safety: Designed to comply with the IEC 61508 SIL2 system functional safety standard.

Typical Applications：

Complex Industrial Automation: Large-scale Programmable Logic Controllers (PLC), Industrial PCs (IPC), multi-axis motion control cards, distributed I/O systems.

High-End Multi-Axis Motor Drives: Industrial robot controllers, CNC machine tool servo systems, textile machinery multi-motor synchronous control.

High-Power Digital Energy Systems: High-power photovoltaic/energy storage inverters, electric vehicle charging pile main control units, server cluster power management units.

Networked & Control-Intensive Devices: Gateways or main controllers that require simultaneous handling of multiple Ethernet/CAN-FD communications, multi-channel high-precision analog signals, and a large number of digital I/Os.
