Should l Buy STM?
STMicroelectronics announced the start of general-purpose STM32 microcontroller deliveries manufactured in China. The first batch of STM32 wafers fully produced in China by Huahong for ST is now being delivered to customers in China. The company said 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. Through this collaboration, STMicroelectronics has 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 technology and quality control standard as in ST's global fabs, to ensure compatibility of China-manufactured products with ST's global quality standards. The packaging and testing are handled by ST's Shenzhen fab and local semiconductor assembly and test partners. This manufacturing model offers customers in China a dual-supply choice between MCUs manufactured locally and those produced outside China.
