STM32 is a family of 32-bit microcontroller and microprocessor integrated circuits by STMicroelectronics. STM32 microcontrollers are grouped into related series that are based around the same 32-bit ARM processor core: Cortex-M0, Cortex-M0+, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M33, or Cortex-M55. Internally, each microcontroller consists of ARM processor core(s), flash memory, static RAM, a debugging interface, and various peripherals.^[1]

In addition to its microcontroller lines, STMicroelectronics has introduced microprocessor (MPU) offerings such as the MP1 and MP2 series into the STM32 family. These processors are based around single or dual ARM Cortex-A cores combined with an ARM Cortex-M core.^[9] Cortex-A application processors include a memory management unit (MMU),^[10] enabling them to run advanced operating systems such as Linux.
