http://www.st.com/content/st_com/en/products/microcontrollers/stm32-32-bit-
arm-cortex-mcus.html
The STM32 family of 32-bit Flash microcontrollers
based on the ARM Cortex-M processor is designed
to oﬀer new degrees of freedom to MCU users. It
oﬀers a 32-bit product range that combines very
high performance, real-time capabilities, digital
signal processing, and low-power, low-voltage
operation, while maintaining full integration and
ease of development.
