GigaDevice Elevates Entry-Level MCU Standards with New GD32C231 Series

GD32C231

GigaDevice, a semiconductor company specializing in Flash memory, 32-bit microcontrollers (MCUs), sensors, and analog products, has announced the launch of its new GD32C231 series microcontrollers (MCUs), extending its lineup based on the Arm® Cortex®-M23 core. Positioned as a high-performance yet cost-effective solution, the new series is aimed at entry-level applications across consumer electronics, industrial systems, and the automotive aftermarket.

The GD32C231 MCUs are designed to meet growing market demand for budget-friendly components that do not compromise on performance. Leveraging the Cortex-M23 architecture, the series offers up to 10% higher computational performance compared to traditional Cortex-M0+ based MCUs. With a maximum clock speed of 48MHz and efficient instruction support such as integer division, the devices are suited for applications including battery management systems (BMS), handheld consumer products, and small-screen display devices.

Memory configurations in the GD32C231 series range from 32KB to 64KB of embedded Flash and 12KB of SRAM. Both memory types include ECC (Error Correction Code) protection, a feature often absent in this category, reinforcing the MCUs’ reliability for safety-sensitive applications. Multiple package options—such as TSSOP20, QFN32, and LQFP48—allow for design flexibility across varied product needs.

To enhance cost-efficiency, the GD32C231 series integrates a high number of peripherals within a single chip. These include a 12-bit ADC with 13 channels, hardware comparators, multiple general-purpose and advanced 16-bit timers, SPI/QSPI and I²C interfaces, UARTs with up to 6Mbps data rate, and a 3-channel DMA controller. An I²S interface is also included for audio applications, while up to 45 GPIOs are available in the largest package variant.

GigaDevice has engineered the new MCUs for robust field use. The GD32C231 operates within a voltage range of 1.8V to 5.5V and a temperature range of -40°C to 105°C, making it suitable for industrial and automotive deployments. The devices support ultra-low-power modes with deep sleep current as low as 5µA and a wake-up time of just 2.6µs, enabling efficient power management in battery-operated systems.

For signal integrity and system reliability, the series meets 8kV contact and 15kV air discharge ESD standards. A hardware CRC module ensures data transmission reliability in communication-intensive environments. These features make the GD32C231 series attractive for designers of low-power, high-reliability systems in industrial automation and consumer electronics.

In addition to hardware specifications, GigaDevice is offering a complete development ecosystem for the GD32C231 series. Developers have access to standard software libraries, datasheets, application notes, and user manuals. The company’s proprietary IDE, GD32 Embedded Builder, includes graphical configuration and intelligent code generation, streamlining embedded system design. FreeRTOS support is built-in for real-time applications.

Programming and debugging tools such as the GD32 All-In-One Programmer and GD-Link debugger offer streamlined workflows, with support for industry-standard protocols like SWD and JTAG. The MCUs are fully compatible with third-party development platforms, including Arm Keil, IAR Embedded Workbench, and SEGGER Embedded Studio. GigaDevice also offers pre-configured SDKs, example code, and reference designs to help accelerate time to market.

The launch of the GD32C231 marks GigaDevice’s continued expansion within China’s Arm MCU market and aligns with its strategy to strengthen its presence in cost-sensitive, high-volume product segments. With more than 2 billion MCUs shipped to date and a strong global supply chain, the company is positioning this new series to appeal to OEMs and system designers looking for reliable, entry-level computing power without sacrificing performance.

Founded in 2005 and headquartered globally in Singapore since 2025, GigaDevice has steadily expanded its footprint across industrial, automotive, consumer, IoT, and networking domains. The firm holds multiple international certifications, including ISO26262 ASIL D and IEC 61508 for functional safety, underscoring its commitment to quality and safety in semiconductor design and manufacturing.

The GD32C231 is expected to see strong uptake in applications where cost, power efficiency, and feature-rich integration are primary considerations. Its performance and ecosystem compatibility may also appeal to embedded developers and system integrators seeking scalable MCU solutions for evolving application needs.
