- Core:
- ARM Cortex-M4F core at a maximum clock rate of 72 MHz.
- Memory:
- Static RAM consists of 16 / 24 / 32 / 40 KB general purpose with hardware parity check, 0 / 8 KB core coupled memory (CCM) with hardware parity check, 64 / 128 bytes battery-backed with tamper-detection erase.
- Flash consists of 64 / 128 / 256 KB general purpose, 8 KB system boot, and option bytes.
- Each chip has a factory-programmed 96-bit unique device identifier number.
- Peripherals:
- Each F3-series includes various peripherals that vary from line to line.

- 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 op-amps 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 op-amps 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.
The four ADCs can be simultaneously sampled making a wide range of precision analogue control equipment possible. It is also possible to use a hardware scheduler for the multiplexer array, allowing good timing accuracy when sampling more than 4 channels, independent of the main processor thread. The sampling and multiplexing trigger can be controlled from a variety of sources including timers and built-in comparators, allowing for irregular sampling intervals where needed.
The op-amps inputs feature 2-to-1 analogue multiplexer, allowing for a total of eight analogue channels to be pre-processed using the op-amp; all the op-amp outputs can be internally connected to ADCs.

STM32
- Design utilities
- STM32CubeMX, by STMicroelectronics, a freeware package for Windows, Mac OS X and Linux that is a graphical software configuration tool that allows generating C initialization code using graphical wizards. The package was first release in February 2014 with graphical peripheral allocation support for every STM32 chip. As of January 2015, the tool supports all STM32 series. It can generate source code usable directly on the most current ARM Cortex-M IDEs, including the free System Workbench for STM32 IDE. The source code generated by STM32CubeMX is licensed under the 3-clause BSD License,[71] making it suitable for commercial as well as open source applications. STM32CubeMX is likely an evolution of the former MicroXplorer tool, because the saved "IOC" configuration file from STM32CubeMX shows the word "MicroXplorer" in it. A 32-bit Java Runtime Environment (JRE) must be installed prior to running STM32CubeMX.[72]
- Debug utilities
- STM-STUDIO, by STMicroelectronics, a freeware package for Windows to help debug and diagnose STM32 applications while they are running by reading and displaying their variables in real-time. STM-STUDIO connects to any STM32 using any ST-LINK type of device via JTAG or SWD debug bus protocols. It can log captured data to a file and replay later. It parses debugging information from the ELF application executable file. A 32-bit Java Runtime Environment (JRE) must be installed prior to running STM-STUDIO. The STM32 ST-LINK Utility must be installed prior to running STM-STUDIO.[72]
- System Workbench for STM32, by Ac6, a freeware IDE running on Windows, Linux and Mac OS X to develop, debug and diagnose STM32 applications. System Workbench for STM32 can be used to develop on any STM32 using any ST-LINK/V2 type of device via JTAG or SWD debug bus protocols. It is based on Eclipse and the GNU GCC toolchain and supports out-of-the-box all ST-provided evaluation boards (Eval, Discovery or Nucleo). A 32-bit Java Runtime Environment (JRE[72]) will automatically be installed if needed as well as the STM32 ST-LINK driver.
- VisualGDB, by Sysprogs, a debug plugin for Microsoft Visual Studio that allows developing and debugging STM32 applications.
- EPS Debugger, by Comsytec, a debug plugin for Code::Blocks that includes compiler, debugger, project wizard for STM32.
- Flash programming via USB
- STM32 ST-LINK Utility, by STMicroelectronics, a freeware package for Windows to perform in-system programming of STM32 microcontrollers using the USB-based ST-LINK/V2 interface device via JTAG or SWD debug bus protocols. This software can upgrade the firmware in the ST-LINK device, which includes the embedded ST-LINK on all of the STM32 DISCOVERY boards.[73] During installation of this utility, a USB driver is installed to provide a communication interface with the ST-LINK device, which in turn also allows various IDEs to use the ST-LINK for debugging.
- ST Visual Programmer (STVP), by STMicroelectronics, a freeware package for Windows to perform in-system programming of the flash in STM32 microcontrollers using a USB-based ST-LINK device.
- DfuSe, by STMicroelectronics, a freeware package for Windows to load DFU programs into the flash of USB-based STM32 microcontrollers.
- qstlink2, an open source multi-platform ST-LINK/V2 client, based on QT.
- texane stlink, an opensource ST-LINK/V2 client for linux
- pystlink, an opensource ST-LINK/V2 programmer and debug tool with simple command-line interface for Linux, Mac OS X and Windows written in Python 3.
- 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).
- stm32flash, an open source program for Windows and Linux to perform in-system programming of the STM32 flash via its USART.
- stm32loader, an open source multi-platform Python script to perform in-system programming of the STM32 flash via its USART. Python and Python Serial Port Extension must be installed prior to running stm32loader.
- STM32 Java software libraries
- Standard Eclipse Java IDE STM32Java
- STM32 C/C++ software libraries
- Standard peripheral library.
- FreeRTOS
- USB device library.
- DSP library.
- Encryption library.
- Motor control library.
- MP3 / WMA / Speex codecs and audio engine.
- Self-test routines.
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: manufacturer website, manufacturer marketing slides, manufacturer datasheet for the exact physical chip, manufacturer detailed reference manual that describes common peripherals and aspects of a physical chip family, ARM core generic user guide, ARM core technical reference manual, ARM architecture reference manual that describes the instruction set(s).
