GigaDevice GD32F5xx and GD32G5xx Software Test Libraries (STL) Receive TÜV Rheinland IEC 61508 Functional Safety Certification

About this update from Giga Device Semiconductor Inc. Class A

BEIJING, October 29, 2025 --( BUSINESS WIRE )--GigaDevice, a leading semiconductor company specializing in Flash memory, 32-bit microcontrollers (MCUs), sensors, and analog products, announced that its GD32F5xx and GD32G5xx Software Test Libraries have received IEC 61508 SC3 (SIL 2/SIL 3) functional safety certification from TÜV Rheinland. This milestone expands GigaDevice’s functional safety portfolio, which already includes the GD32H7 and GD32F30x STLs, and now covers a broad range of MCUs with Arm® Cortex®-M7, Cortex®-M4, and Cortex®-M33 cores. Building on this foundation, GigaDevice will continue to deliver high-performance and safety-focused hardware and software solutions for key applications such as industrial control , energy and power , and humanoid robotics . With the growing emphasis on safety across industries like industrial automation, functional safety has become a critical consideration in embedded system design. The GD32F5xx and GD32G5xx MCUs, based on the Arm® Cortex®-M33 core, have become key solutions for high-performance applications requiring robust safety measures. The GigaDevice STLs monitor GD32F5xx and GD32G5xx MCU modules in real-time to detect hardware faults. If a fault is detected, predefined safety mechanisms will be triggered to ensure the MCU always remains in a safe state, reducing potential risks and enhancing system reliability. This certification highlights GigaDevice's deep expertise in functional safety system design and its commitment to meeting the highest international safety standards, reinforcing its position as a trusted provider of secure, high-performance solutions for mission-critical industries.
