The STM32 family of 32-bit Flash microcontrollers is based on the breakthrough ARM Cortex-M3 core – a core specifically developed for embedded applications requiring a combination of high performance, low power and low cost. The STM32 family benefits from the Cortex-M3 architectural enhancements, including the Thumb-2® instruction set to deliver improved performance combined with better code density, and a tightly coupled nested vectored interrupt controller for significantly faster response to interrupts, all combined with industry-leading power consumption. STMicroelectronics was a lead partner in developing the Cortex-M3 core and is now the first leading MCU supplier to introduce a product family based on the core. Welcome to the world of STM32.

The STM32 family is built to offer new degrees of freedom to MCU users. It offers a complete 32-bit product range that combines high performance, low power and low voltage, while maintaining full integration and ease of development.

It eases migration from the 16-bit world thanks to its high level of features integration, its easy-to-use architecture, its low power capability and cost-effectiveness.

This new family will enable you to create new applications, and design in the innovations you have been long dreaming about.
