By choosing one of ST's microcontrollers & microprocessors for your embedded application, you gain from our leading expertise in scalable computing architecture, silicon technology, wireless state-of-the-art IPs and software stacks, embedded real-time and application software, multi-source manufacturing and worldwide support.
ST offers a wide-ranging microcontroller product portfolio, Arm®-based Cortex®-M 32-bit with a comprehensive choice of peripherals. Its breadth ensures that design engineers will find the mix of performance, power efficiency and security that is required by their application.
With the addition of the STM32 Microprocessor (MPU) and its heterogeneous architecture combining Arm® Cortex®-A and Cortex®-M cores, embedded system engineers are given new design possibilities and access to open-source Linux and Android platforms. The STM32 family of general-purpose application processors is scalable from 32 to 64-bit platforms.
This flexible architecture allows the advanced digital and analog peripherals to be allocated to either core, while achieving the best power efficiency depending on processing and real-time execution requirements. To help engineers reduce application development time, a fully mainlined open-source Linux distribution and a new-generation system toolset from ST and 3rd parties are now available for STM32 MCUs and MPUs.
