September 15, 2025 – SGS, a globally recognized third-party testing, inspection, and certification organization, held a joint certification ceremony with Geehy Semiconductor Co., Ltd. (“Geehy”) to officially award the SGS-TÜV SAAR IEC 61508 Functional Safety Product Certification to the Geehy G32R501D real-time MCU series.
This certification confirms that the Geehy G32R501D series has achieved internationally advanced standards in industrial functional safety. It provides reliable technical assurance for high-end applications including industrial automation, smart energy, new energy vehicles, and robotics.
G32R501D Certified to IEC 61508 SIL 2
Ensuring Safe and Reliable Performance
in Industrial and Automotive Systems
IEC 61508, recognized as the “gold standard” in functional safety, defines the requirements for Safety Integrity Levels (SIL) in electronic, electrical, and programmable logic devices, covering the entire lifecycle from chip design to application deployment. In the certification process, the SGS functional safety team contributed its technical expertise and experience in safety evaluation, supporting key stages such as G32R501D’s safety design, risk analysis, testing, and validation. Each step followed the principles of “compliance, rigor, and foresight”, ensuring efficiency and robustness. The final evaluation confirmed that the G32R501D meets the IEC 61508 SIL 2 SC3 safety integrity standards, offering advanced fault detection and fault tolerance capabilities that significantly reduce risks associated with random hardware failures.
Dual Review from China and Germany
Highlights Certification Authority and Product Strength
The certification process began with SGS China’s functional safety team, which conducted a thorough preliminary review of the chip’s technical solutions, test data, STL libraries, and key documents including the Safety Requirements Specification (SRS), architecture design, FMEDA report, and safety manual. The final review was conducted by SGS-TÜV SAAR in Germany, applying international standards to verify full compliance with IEC 61508, SIL 2, SC3. This rigorous dual review ensures that the Geehy G32R501D delivers both “local adaptability” and “global applicability.” This achievement not only validates the MCU’s strong safety design capabilities but also positions it for seamless adoption in global high-safety-level industrial applications, reinforcing Geehy’s competitiveness in the international market.
Additionally, the G32R501D passed the AEC-Q100 Grade 1 automotive reliability qualification, guaranteeing stable operation across a wide temperature range (-40°C to 125°C) to meet the strict demands of automotive electronics.
Currently, the Geehy G32R501D is the first China-developed real-time MCU to achieve both IEC 61508 functional safety certification and AEC-Q100 reliability qualification. This dual recognition highlights Geehy’s expertise in functional safety design, chip development, and system integration, while demonstrating its commitment to performance, reliability, and safety.
