STMicroelectronics N.V. (NYSE:STM) on Monday announced it has started volume production and deliveries of STM32 microcontrollers manufactured in China, with initial wafers produced by Huahong Group now shipping to local customers.

The move establishes a fully localized supply chain, from wafer fabrication to packaging and testing, while maintaining global quality standards. ST said it is the first global chipmaker to offer a dual supply model, allowing customers to choose between China-made and overseas-produced chips with identical design and performance.

Mass production has begun for the STM32H7 series, with additional models, including STM32H5 and STM32C5, set to roll out by the end of 2026.
