Features
• Based on FreeRTOS
™
kernel release 10.4.6
• Integrated and full-featured operating system: FreeRTOS
™
kernel
• CMSIS RTOS V2 adaptation layer
• Many applicative examples available for the STMicroelectronics NUCLEO-
U575ZI-Q and NUCLEO-H563ZI boards
• Free user-friendly license terms
• Enhanced for the STMicroelectronics toolset: graphical configuration of
FreeRTOS
™
kernel with STM32CubeMX and STM32CubeIDE
• Update mechanism, which can be enabled by the user to be notified of new
releases
Description
X-CUBE-FREERTOS (FreeRTOS
™
software expansion for STM32Cube) provides a
full integration of the FreeRTOS
™
kernel in the STM32Cube environment for the
STM32U5 series and STM32H5 series of microcontrollers. Ready-to-run applicative
examples provided for the NUCLEO-U575ZI-Q and NUCLEO-H563ZI evaluation
boards, along with a full compatibility with STM32CubeMX and STM32CubeIDE,
ensure that X-CUBE-FREERTOS drastically reduces the learning curve and provides
a smooth application development experience with FreeRTOS
™
kernel and the
STM32U5 and STM32H5 microcontrollers.
The CMSIS RTOS V2 adaptation layer is included and demonstrated, making it easy
and quick to migrate from another RTOS.
X-CUBE-FREERTOS is only an STM32Cube integration of the FreeRTOS
™
kernel.
Other FreeRTOS
™
libraries are not part of X-CUBE-FREERTOS, which therefore
does not support native connectivity to the AWS Cloud.

Ordering information
X-CUBE-FREERTOS is available for free download from the www.st.com website and through the
STM32CubeMX and STM32CubeIDE software tools.
1.2 What is STM32Cube?
STM32Cube is an STMicroelectronics original initiative to improve designer productivity significantly by reducing
development effort, time, and cost. STM32Cube covers the whole STM32 portfolio.
STM32Cube includes:
• A set of user-friendly software development tools to cover project development from conception to
realization, among which are:
– STM32CubeMX, a graphical software configuration tool that allows the automatic generation of C
initialization code using graphical wizards
– STM32CubeIDE, an all-in-one development tool with peripheral configuration, code generation, code
compilation, and debug features
– STM32CubeCLT, an all-in-one command-line development toolset with code compilation, board
programming, and debug features
– STM32CubeProgrammer (STM32CubeProg), a programming tool available in graphical and
command-line versions
– STM32CubeMonitor (STM32CubeMonitor, STM32CubeMonPwr, STM32CubeMonRF,
STM32CubeMonUCPD), powerful monitoring tools to fine-tune the behavior and performance of
STM32 applications in real time
• STM32Cube MCU and MPU Packages, comprehensive embedded-software platforms specific to each
microcontroller and microprocessor series (such as STM32CubeU5 for the STM32U5 series), which
include:
– STM32Cube hardware abstraction layer (HAL), ensuring maximized portability across the STM32
portfolio
– STM32Cube low-layer APIs, ensuring the best performance and footprints with a high degree of user
control over hardware
– A consistent set of middleware components such as ThreadX, FileX / LevelX, NetX Duo, USBX,
USB-PD, touch library, network library, mbed-crypto, TFM, and OpenBL
– All embedded software utilities with full sets of peripheral and applicative examples
• STM32Cube Expansion Packages, which contain embedded software components that complement the
functionalities of the STM32Cube MCU and MPU Packages with:
– Middleware extensions and applicative layers
– Examples running on some specific STMicroelectronics development boards
