STM32 Microcontrollers

STM32 is a family of 32-bit microcontrollers based on the ARM Cortex-M processor, produced by STMicroelectronics.

Core Architectures​

The STM32 family covers various performance levels:

  • Cortex-M7F: High-performance (STM32H7, STM32F7).
  • Cortex-M4F: Mainstream with Floating Point Unit (STM32F4, STM32L4).
  • Cortex-M3: Standard performance (STM32F1, STM32F2, STM32L1).
  • Cortex-M0 / M0+: Entry-level and low-power (STM32F0, STM32L0, STM32G0).

Development Ecosystem​

Hardware Tools​

  • Nucleo Boards: Low-cost development boards with Arduino-compatible headers.
  • Discovery Kits: Feature-rich boards with onboard sensors, displays, and debuggers.
  • ST-LINK: The official hardware debugger and programmer.

Software Tools​

  • STM32CubeMX: Graphical tool for MCU configuration and initialization code generation.
  • STM32CubeIDE: All-in-one multi-OS development tool based on Eclipse/GCC.
  • PlatformIO: Modern, VSCode-based ecosystem for embedded development.
  • Keil MDK / IAR EWARM: High-end commercial IDEs.
