    Beijing, China (October 24, 2025) - GigaDevice, a leading semiconductor device supplier (stock code: 603986), announced that The STL (Software Test Library) software test library that is compatible with its GD32F5xx and GD32G5xx series MCUS has been awarded the IEC 61508 SC3 (SIL 2/SIL 3) functional safety certification by TuV Rheinland of Germany. This is another significant expansion of GigaDevice in the field of functional safety following the GD32H7 and GD32F30x STL, and it has achieved full coverage of Arm Cortex-M7, Cortex-M4 and Cortex-M33 core MCUS. Relying on this layout, GigaDevice will continue to provide high-performance and high-security diversified products and supporting software solutions for customers in key fields such as global industrial control, energy and power, and humanoid robots.

    With the continuous improvement of safety requirements in fields such as industrial automation, functional safety has become a core element in the design of embedded systems. Gigadevice's GD32F5xx and GD32G5xx series of MCUS based on the Arm Cortex-M33 core have developed into important choices for high-performance industrial applications. Among them, the GD32F5xx series of MCUS are mainly targeted at application fields such as energy and power, photovoltaic energy storage, and industrial automation, which have strict requirements for processing performance and control accuracy. The GD32G5xx series, with its outstanding processing performance, rich and diverse digital-analog interface resources, and multiple packaging forms including the WLCSP81(4x4) ultra-small package, is widely applicable to various scenarios such as humanoid robots, digital power supplies, charging piles, energy storage inverters, frequency converters, servo motors, and optical communications. The STL software test library that comes with it can conduct real-time monitoring and system checks on the internal modules of the MCU, effectively detect random hardware faults, and immediately trigger the preset security response mechanism upon identifying an anomaly, ensuring that the MCU is always in a safe state and thereby reducing potential risks and hidden dangers.
  The acquisition of this certification not only highlights GigaDevice's profound accumulation in the construction of functional safety systems, technical implementation and process management, but also reflects the company's continuous adherence to and firm commitment to international safety standards. In the future, GigaDevice will continue to promote the in-depth layout of functional safety in its diverse product lines, and is committed to empowering the intelligent upgrade and high-quality development of thousands of industries with safer and more reliable products.
