Product Description：

The GigaDevice GD32G553MEY7TR is a high-performance 32-bit microcontroller from the GD32G5 series, built around the 216 MHz Arm® Cortex®-M33 core . It is engineered for demanding real-time control tasks in applications like digital power, motor drives, and industrial automation. A key differentiator of this specific model is its ultra-compact WLCSP (Wafer-Level Chip-Scale Package), making it particularly suitable for space-constrained designs such as robotic joints and compact motor drives .

Main Features：

High-Performance Core: Based on the Arm® Cortex®-M33 core with a maximum frequency of 216 MHz. Equipped with a Single-Precision Floating-Point Unit (FPU) and a Trigonometric Mathematics Unit (TMU).

Advanced Peripherals & Control:

High-Resolution Timer (HRTIM): Provides PWM resolution as high as 145ps, which is crucial for achieving efficient digital power (e.g., photovoltaic microinverters) and precision motor control.

High-Speed Analog Peripherals: Includes high-speed ADCs, DACs, and comparators (CMP), supporting rapid signal acquisition and processing.

Rich Connectivity: Integrates various communication interfaces (e.g., CAN-FD, SPI, I2C) and hardware cryptographic modules (AES, TRNG), supporting security features.

Ultra-Compact Package (Key Differentiator): Utilizes an 81-pin WLCSP package with an extremely small form factor (typically 4×4 mm), significantly saving PCB area.

Industrial-Grade Reliability: Operating temperature range of -40°C to +105°C, meeting industrial environment requirements.

Packaging Form: The suffix "TR" indicates Tape and Reel packaging, suitable for automated SMT production.

Typical Applications：

Its high performance and small package size make it particularly suitable for the following fields:

Space-Constrained Mechatronic Devices: Robot dexterous hands, joint motors, encoders.

High-Power-Density Digital Energy: Photovoltaic microinverters, AI server power supplies, compact motor drives.

High-End Industrial Control: Equipment requiring high-performance real-time control where PCB space is precious.
