GD32 Entry-Level Microcontrollers: Cost-Effective 32-bit Embedded Solutions

GigaDevice's GD32 series of microcontrollers (MCUs) occupy an important position in the embedded market due to their high performance and low cost. Designed for cost-sensitive application scenarios, its entry-level product line offers powerful computing capabilities, rich peripheral resources, and low-power features, making it an ideal replacement for traditional 8- or 16-bit MCUs.

Core Features

1.High-efficiency core 

The GD32 entry-level microcontrollers are powered by the Arm Cortex-M23 core at up to 72 MHz. Cortex-M23 is Arm's next-generation, low-power core that is compatible with the Cortex-M0/M0+ instruction set, while providing more efficient hardware support such as single-cycle multipliers and 17-cycle dividers.

2. Flexible Memory Configuration

- Provides up to 128KB on-chip Flash memory and 16KB SRAM to meet the needs of various embedded applications.

- Supports 0-2 wait state Flash access to optimise operation efficiency.

3. Rich Peripherals

- Integrate a variety of peripheral resources, including:

- 12-bit ADC (supports up to 10 channels).

- Comparator, PWM advanced timer and multiple 16-bit timers.

- Standard communication interfaces (e.g. SPI, I2C, USART) and audio interfaces (e.g. I2S).

- Multiple package formats (e.g., QFN, LQFP, TSSOP) are available to suit different design requirements.

4. Low power consumption design

- Supports three power saving modes to balance power consumption and wake-up delay.

- With an operating voltage range of 1.8V to 3.6V, the GD32 is suitable for portable and battery-powered devices.

5. High Compatibility 

The GD32 entry-level MCUs are highly compatible with other GD32 series products in terms of hardware pins and software code, such as the GD32F130/150 series. This compatibility simplifies developers' migration between product lines.

Typical Application Scenarios

GD32 entry-level microcontrollers are widely used in the following areas:

- Industrial control and motor drive: Used in scenarios such as automation equipment and inverter drives to provide efficient real-time control capabilities.

- Consumer electronics and handheld devices: for small devices such as e-bikes, electronic toys, GPS modules, etc.

- Human-machine interface and alarm system: supports touch panel, power monitoring and alarm functions.

- Internet of Things and Smart Home: Meet the demand for low power consumption and high integration for smart home and smart city.

Representative products: GD32E23x series

The GD32E23x series represents the GD32 entry-level product line with the following features:

- Based on Cortex-M23 core with 72MHz main frequency.

- Multiple memory configurations from 16KB to 128KB Flash, and 4KB to 16KB SRAM.

- Integrated rich I/O interfaces and peripheral resources, such as 12-bit ADC, PWM timer and a variety of communication interfaces.

- Flexible packages, including QFN28, LQFP48, etc., to meet different design requirements.

Summary of Advantages

1. Cost-effective: Providing powerful performance while maintaining low cost, it is an excellent choice to replace traditional 8-bit or 16-bit MCUs.

2. Flexibility: Hardware and software compatibility makes it adaptable to diversified development needs.

3. Low power performance: Suitable for scenarios with high energy efficiency requirements, such as IoT and portable devices.
