By choosing one of ST's microcontrollers & microprocessors for your embedded application, you benefit 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's wide-ranging microcontroller product portfolio spans from robust, low-cost  8-bit MCUs up to  32-bit Arm®-based Cortex®-M microcontrollers 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 for their application.

The  STM32 Microcontroller (MCU) portfolio also features wireless connectivity solutions including our ultra-low-power,  dual-core STM32WB microcontroller series. This multi-protocol wireless MCU platform is able to run Bluetooth™ 5.0, OpenThread, ZigBee 3.0 and IEE 802.15.4 communication protocols concurrently.

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. 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 3 rd parties are now available for STM32 MCUs and MPUs.
