STMicroelectronics (NYSE: STM) has announced a unified STM32 microcontroller platform covering industrial, automotive and robotics applications. The new platform is designed to help developers reuse architectures, software, intellectual property and development tools across different product categories, reducing development time and simplifying the design of embedded systems.
The announcement was made at STM32 Summit 2026. As part of the new strategy, ST has introduced the STM32A family, extending the STM32 portfolio into automotive and safety-critical applications. The platform builds on more than 20 years of STM32 development and is intended to support emerging technologies, including physical artificial intelligence (AI).
Remi El-Ouazzane, President of the Microcontrollers, Digital ICs and RF Products Group at STMicroelectronics, said the unified platform would give developers a common foundation across different markets and product generations. He noted that greater software reuse and reduced fragmentation would help customers develop new embedded products without having to rebuild their systems for every application.
The move reflects the growing overlap between industrial and automotive technologies. As more intelligence is built into machines, vehicles and robots, these applications increasingly require real-time control, secure operation, functional safety, connectivity and AI processing. The unified STM32 platform is designed to address these common requirements while allowing customers to select products suited to the performance, safety, qualification and operating-life needs of individual applications.
The platform will use Arm Cortex-M processor cores and shared architectural principles to support software and intellectual property reuse across STM32 families. Developers will also have access to STM32Cube, ST’s microcontroller software ecosystem, along with tools, technical resources and support from the wider Arm developer community. Its manufacturing foundation includes ST’s 40nm Flash and 18nm FD-SOI technologies with embedded phase-change memory, as well as TSMC embedded non-volatile memory technologies.
ST and Arm are working together to advance the Cortex-M portfolio for applications requiring greater processing capabilities at the edge. Drew Henry, Executive Vice President of Physical AI at Arm, said the collaboration would help develop computing technologies for machines used in transportation, manufacturing and industrial operations.
The new STM32A family includes three microcontrollers. The STM32A4 is designed for entry-level automotive local control nodes and safety systems. The STM32A5 targets mid-range safety-critical applications in industrial automation, robotics and energy systems, as well as automotive applications. The STM32A9 is intended for safety-critical multi-domain control requiring real-time processing, low latency, Ethernet and deterministic communication. The first three STM32A products are being sampled to customers, with wider availability planned for 2027.
STMicroelectronics employs around 49,000 people and works with more than 200,000 customers and thousands of partners worldwide. The company develops semiconductor technologies for smarter mobility, power and energy management, and connected autonomous systems. ST has also set a target to achieve carbon neutrality across its direct and indirect emissions, product transportation, business travel and employee commuting, and to source 100% renewable electricity by the end of 2027.
