One unified MCU platform for scalability and faster time to market
STM32 offers a broad portfolio of 32-bit microcontrollers in one unified platform, built on the industry-standard Arm Cortex-M core, a common ecosystem foundation adopted by close to 2 million developers worldwide, and shared process technologies. This unified platform approach fosters reuse, scalability, and helps teams move more easily from one design to the next.
STM32 provides cross-domain microcontrollers, with a portfolio of more than 5,000 part numbers spanning general-purpose to high-safety and automotive microcontrollers.
