STM32 Arm Cortex MPUs

Industrial-grade microprocessors

Complex embedded systems in industrial and consumer applications manage high processing loads in real time, while providing with rich human machine interfaces (HMIs) and optimizing power consumption.

The STM32 family of general-purpose 32-bit microprocessors (MPUs) provides developers with greater design flexibility and performance. STM32 microprocessors are based on single or dual Arm® Cortex®-A cores, combined with a Cortex®-M core. From cost-effective, single-core MPUs to more advanced, multicore MPUs, ST offers a scalable approach to help developers find the right fit.

A strong, user-friendly ecosystem

STM32 microprocessors leverage the proven software, tools, and technical support provided by the STM32 family ecosystem.

  • They come with the OpenSTLinux Distribution, which is a mainlined open-source Linux distribution. It contains all the essential building blocks for running software on microprocessor cores.
    • OpenSTLinux is reviewed and accepted by the Linux community (Linux Foundation, Yocto Project, and Linaro).
    • It is preintegrated within the OP-TEE secure OS.
    • OpenSTLinux is provided with Microsoft Azure RTOS components, enabling real-time performance.
  • Evaluation boards and discovery kits are available to accelerate development.

STM32 MPUs are pin-to-pin compatible within each product line, allowing developers to reuse software seamlessly and migrate IPs from project to project. The packages are compatible with low-cost PCB technologies (down to 4-layer plated-through hole PCBs) and can be combined with a dedicated power management IC (PMIC).

STM32 microprocessors are included in ST's 10-year longevity commitment program. They are available at distributors worldwide.


The STM32 MPUs are designed for Industry 4.0, smart homes, and smart cities.
