STM32 Microcontrollers | STM32: STM32 Microcontrollers, STM32 is a family of microcontroller ICs based on the 32-bit RISC ARM Cortex-M33F, Cortex-M7F, Cortex-M4F, Cortex-M3, Cortex-M0+, and Cortex-M0 cores. STMicroelectronics licenses the ARM Processor IP from ARM Holdings. The ARM core designs have numerous configurable options, and ST chooses the individual configuration to use for each design. ST attaches their own peripherals to the core before converting the design into a silicon die. The following tables summarize the STM32 microcontroller families.

STM32 Series
The STM32 family consists of ten series of microcontrollers: H7, F7, F4, F3, F2, F1, F0, L4, L1, L0,. Each STM32 microcontroller series is based upon either a Cortex-M7F, Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0 ARM processor core. The Cortex-M4F is conceptually a Cortex-M3 plus DSP and single-precision floating point instructions.
- STM32 H7: The STM32 H7-series is a group of STM32 microcontrollers based on the ARM Cortex-M7F core.
- STM32 F7: The STM32 F7-series is a group of STM32 microcontrollers based on the ARM Cortex-M7F core. Many of the F7 series are pin-to-pin compatible with the STM32 F4-series. (ARM Cortex-M7F core at a maximum clock rate of 216 MHz.)
- STM32 F4: The STM32 F4-series is the first group of STM32 microcontrollers based on the ARM Cortex-M4F core. The F4-series is also the first STM32 series to have DSP and floating point instructions. The F4 is pin-to-pin compatible with the STM32 F2-series and adds higher clock speed, 64 KB CCM static RAM, full duplex I²S, improved real-time clock, and faster ADCs.
- STM32 F3: The STM32 F3-series is the second group of STM32 microcontrollers based on the ARM Cortex-M4F core. The F3 is almost pin-to-pin compatible with the STM32 F1-series.
- STM32 F2: The STM32 F2-series of STM32 microcontrollers based on the ARM Cortex-M3 core. It is the most recent and fastest Cortex-M3 series. The F2 is pin-to-pin compatible with the STM32 F4-series.
- STM32 F1: The STM32 F1-series was the first group of STM32 microcontrollers based on the ARM Cortex-M3 core and considered their mainstream ARM microcontrollers. The F1-series has evolved over time by increasing CPU speed, size of internal memory, variety of peripherals. There are five F1 lines: Connectivity (STM32F105/107), Performance (STM32F103), USB Access (STM32F102), Access (STM32F101), Value (STM32F100).
- STM32 F0: The STM32 F0-series are the first group of ARM Cortex-M0 chips in the STM32 family.
- STM32 G0: The STM32 G0-series is a lower power alternative to the L0 series.
