I. Core Functions

• Based on the ARM Cortex-M23 core with a maximum frequency of 72MHz, integrated with 64KB Flash and 8KB SRAM.
• Built-in 12-bit ADC and multi-channel PWM timers, supporting rich communication interfaces including SPI, I2C and USART.
• Wide voltage supply range (1.8–3.6V) with three low-power modes, suitable for battery-powered applications.

II. Main Application Fields

Industrial control, motor drive, smart home, consumer electronics (pulse oximeters/forehead thermometers), electric bicycles, LED displays.

III. Technical Advantages

• High cost-performance ratio, capable of replacing traditional 8/16-bit MCUs and Cortex-M0/M0+ products.
• Industrial-grade temperature range (-40℃~85℃) and 6KV ESD protection for excellent reliability.
• Hardware and software compatibility with other GD32 Value Series products, enabling low-cost development migration.

IV. Summary

As a cost-effective 32-bit MCU, it features a high-efficiency core, rich peripherals and low-power performance. It serves as an ideal choice for mid-to-low-end industrial and consumer electronics scenarios, balancing performance and cost advantages perfectly.
