STM32 32-Bit Arm® Cortex®-M MCUs

STMicroelectronics STM32 32-Bit Arm® Cortex®-M MCUs are based on the Arm Cortex-M processor and designed to offer new degrees of freedom to MCU users. The MCUs offer a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation. This is achieved while maintaining full integration and ease of development.
