All-in-one software Tool For Programming STM32 MCUs


ST has designed an all-in-one multi-OS software tool for programming STM32 microcontrollers (MCUs).

The tool offers device-programming and firmware upgrade for STM32 MCUs in a unified, multi-platform, and user-configurable environment.

Ready to run on Windows, Linux, or MacOS operating systems, the STM32CubeProgrammer can program the STM32 microcontroller’s on-chip Flash/RAM or external memories using various file formats.

Further capabilities include whole-memory or sector erase and programming microcontroller option bytes.


Users can also generate encrypted files for secure programming (Secure Firmware Install/Update) to authenticate production and protect intellectual property.

With this universal tool, users can program STM32 microcontrollers through the device’s SWD (Single-Wire Debug) or JTAG debugging ports, or the bootloader ports (such as UART and USB). Hence the software brings the individual capabilities of the ST Visual Programmer, DFUse Device Firmware Update tool, Flash Loader, and ST-Link utility together within the STM32Cube ecosystem, the company said.

ST plans to extend the STM32CubeProgrammer’s capabilities by adding programming access via microcontroller I2C and CAN ports.

Furthermore, the tool provides many opportunities to customize and configure features, using either the Graphical User Interface (GUI) or the Command-Line Interface (CLI).

Also, this all-in-one tool can be used in standalone mode or integrated and controlled from a custom application. Programming can be done manually or automated using scripts.
