STM32 is a family of 32-bit microcontroller integrated circuits by STMicroelectronics. The STM32 chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals.[1]

Overview

Main articles: ARM architecture and ARM Cortex-M

The STM32 is a family of microcontroller ICs based on the 32-bit RISC ARM Cortex-M4F, Cortex-M3, and Cortex-M0 cores.[1] 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.

Series

The STM32 family consists of seven series of microcontrollers: F4, F3, F2, F1, F0, L1, W.[1] Each STM32 microcontroller series is based upon either a Cortex-M4F, Cortex-M3, or Cortex-M0 ARM processor core. The Cortex-M4F is conceptually a Cortex-M3[3] plus DSP and single-precision floating point instructions.[2]

Microarchitecture ARM Cortex-M4F[2]

The STM32 F4-series is the first group of STM32 microcontrollers based on the ARM Cortex-M4F core.[28] 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, 64K CCM static RAM, full duplex I²S, improved real-time clock, and faster ADCs.[29] The summary for this series is:

  • ARM Cortex-M4F core[2] at a maximum clock rate of 180 MHz.
  • Memory:
    • Static RAM consists of up to 192 KB general purpose, 64 KB core coupled memory (CCM), 4 KB battery-backed, 80 bytes battery-backed with tamper-detection erase.
    • Flash consists of 512 / 1024 / 2048 KB general purpose, 30 KB system boot, 512 bytes one-time programmable (OTP), 16 option bytes.
    • Each chip has a factory-programmed 96-bit unique device identifier number.
  • Common peripherals included in all IC packages are USB 2.0 OTG HS and FS, two CAN 2.0B, one SPI + two SPI or full-duplex I²S, three I²C, four USART, two UART, SDIO for SD/MMC cards, twelve 16-bit timers, two 32-bit timers, two watchdog timers, temperature sensor, 16 or 24 channels into three ADCs, two DACs, 51 to 140 GPIOs, sixteen DMA, improved real-time clock (RTC), cyclic redundancy check (CRC) engine, random number generator (RNG) engine. Larger IC packages add 8/16-bit external memory bus capabilities.

The STM32 F3-series is the second group of STM32 microcontrollers based on the ARM Cortex-M4F core, and the most recent series from ST.[30] The F3 is pin-to-pin compatible with the STM32 F1-series. The summary for this series is:

  • ARM Cortex-M4F core[2] at a maximum clock rate of 72 MHz.

  • Operating voltage range is 2.0 to 3.6 volt.

The distinguishing feature for this series is presence of four fast, 12-bit, simultaneous sampling ADCs (multiplexer to over 30 channels), and interestingly, four matched, 8 MHz bandwidth OpAmps with all pins exposed and additionally internal PGA (Programmable Gain Array) network. The exposed pads allow for a range of analogue signal conditioning circuits like band-pass filters, anti-alias filters, charge amplifiers, integrators/differentiators, 'instrumentation' high-gain differential inputs, and other. This eliminates need for external OpAmps for many applications. The built-in two-channel DAC has arbitrary waveform as well as a hardware-generated waveform (sine, triangle, noise etc.) capability. All analogue devices can be completely independent, or partially internally connected, meaning that one can have nearly everything that is needed for an advanced measurement and sensor interfacing system in a single chip.

Flash programming via USART

All STM32 microcontrollers have a ROM'ed bootloader that supports loading a binary image into its flash memory using one or more peripherals (varies by STM32 family). Since all STM32 bootloaders support loading from the USART peripheral and most boards connect the USART to RS-232 or a USB-to-UART adapter IC, thus it's a universal method to program the STM32 microcontroller. This method requires the target to have a way to enable/disable booting from the ROM'ed bootloader (i.e. jumper / switch / button).

Documentation

The amount of documentation for all ARM chips is daunting, especially for newcomers. The documentation for microcontrollers from past decades would easily be inclusive in a single document, but as chips have evolved so has the documentation grown. The total documentation is especially hard to grasp for all ARM chips since it consists of documents from the IC manufacturer (STMicroelectronics) and documents from CPU core vendor (ARM Holdings).

A typical top-down documentation tree is: high-level marketing slides, datasheet for the exact physical chip, a detailed reference manual that describes common peripherals and other aspects of physical chips within the same series, reference manual for the exact ARM core processor within the chip, reference manual for the ARM architecture of the core which includes detailed description of all instruction sets.

Documentation tree (top to bottom)
  1. STM32 marketing slides.
  2. STM32 datasheets.
  3. STM32 reference manuals.
  4. ARM core reference manuals.
  5. ARM architecture reference manuals.

STMicroelectronics has additional documents, including: evaluation board user manuals, application notes, getting started with development software, software library documents, errata, and more. See the External Links section for documents relating to each STM32 series.
