The first batch of STM32 wafers fully produced in China by Huahong for ST is now being delivered to customers in China. This milestone is a major step forward in ST global supply chain strategy, with additional STM32 families, including performance-oriented, secure, and entry-level microcontroller series, planned for local volume production in 2026. &#34;Bringing STM32 MCUs to mass production in China is a core commitment of ST to its Chinese customers. In collaboration with Huahong, ST is bringing the very same market-leading products to customers with a secure, reliable, and resilient local microcontroller supply chain. ST will continue to respond to the needs of its Chinese customers with greater speed and precision," said Henry Cao, Executive Vice President, Sales &amp; Marketing, China Region, STMicroelectronics. Through this collaboration, STMicroelectronics has become the industry&#39;s first global semiconductor company with a dual supply chain, with fully processed and manufactured 40nm MCU products in China that are exact same design and technology as those made outside China. The company has established a fully localized STM32 supply chain, covering all stages from wafer manufacturing to chip packaging and testing. In front-end wafer manufacturing, ST has strengthened its 15-year partnership with Huahong, leveraging the identical 40 nm embedded non-volatile memory (eNVM) technology and quality control standard as in ST&#39;s global fabs, to ensure seamless compatibility of China-manufactured products with ST's global quality standards. The packaging and testing are handled by ST&#39;s Shenzhen fab and local semiconductor assembly and test (OSAT) partners. This manufacturing model offers customers in China a unique dual-supply choice between MCUs manufactured locally and those produced outside China, while maintaining globally consistent quality and compatibility.
