Description：

The GigaDevice GD32G553CCT7 is a compact and efficient member of the high-performance GD32G5 series. It leverages the powerful 216 MHz Arm® Cortex®-M33 core, delivering the series' signature processing capabilities and high-precision timing in a space-saving 48-pin LQFP package. This model is an ideal choice for cost-sensitive and size-constrained applications that still demand advanced control features, such as compact motor drives, industrial sensors, and mid-range digital power supplies, offering an optimal balance between performance, peripheral set, and system footprint.

Main Features：

1. Core & Performance

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

Hardware Accelerator: Built-in Trigonometric Mathematics Unit (TMU), significantly enhancing the computational efficiency of control loops and algorithms.

2. Advanced Control & Peripherals

Core Control Peripheral: Integrates a High-Resolution Timer (HRTIM) that provides PWM resolution as high as 145ps, forming the foundation for precision control applications.

Analog Peripherals: Equipped with high-speed 12-bit ADC (supporting 5.3 MSPS sampling rate) and high-speed comparators (CMP), meeting real-time signal acquisition and processing needs.

Connectivity: Provides communication interfaces including CAN-FD, USB 2.0 FS, and multiple SPI/I2C/USART to meet mainstream industrial communication requirements. Due to the limitations of the 48-pin package, the availability of some high-speed interfaces (e.g., USB HS) and the number of peripherals may be reduced or require multiplexing.

Security Features: Supports hardware cryptographic modules, providing fundamental system security protection.

3. Memory, Package & Reliability

Memory Configuration: According to model naming conventions, the "C" suffix typically corresponds to 256KB Flash and 128KB SRAM.

Compact Package: The "CC" (or C indicating package type) in the model number denotes the use of a 48-pin LQFP package, one of the packages with fewer pins and smaller size in the series.

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

Typical Applications：

Its compact package and core high performance make it highly suitable for areas that have requirements for space and cost while demanding a certain level of control precision:

Compact Industrial Drives: Medium and low-power servo drives, frequency converters, stepper motor controllers.

Industrial Sensing & Control: High-performance industrial sensors, smart actuators, single-axis motion control modules.

Mid-Range Digital Power Supplies: Power supplies for communication modules, industrial PC power supplies, control units for single-phase photovoltaic microinverters.

High-End Consumer Electronics: Equipment requiring high-performance real-time control, such as drone flight controllers and gimbal stabilizers.
