STM32CubeU5 main features

The STM32CubeU5 MCU package runs on STM32 32-bit microcontrollers based on the Arm® Cortex®-M33

processor with Arm® TrustZone® and FPU.

The STM32CubeU5 gathers, in a single package, all the generic embedded software components required to

develop an application for the STM32U5 series microcontrollers. In line with the STM32Cube initiative, this set of

components is highly portable, not only within the STM32U5 series microcontrollers but also to other STM32

series.

The STM32CubeU5 is fully compatible with the STM32CubeMX code generator for generating initialization code.

The package includes low-layer (LL) and hardware abstraction layer (HAL) APIs that cover the microcontroller

hardware, together with an extensive set of examples running on STMicroelectronics boards. The HAL and LL

APIs are available in open-source BSD license for user convenience.

The STM32CubeU5 MCU package also contains a comprehensive middleware component constructed around

Microsoft® Azure® RTOS middleware and other in-house and open source stacks, with the corresponding

examples.

They come with free user-friendly license terms:

•

Integrated and full featured RTOS: ThreadX

•

CMSIS-RTOS implementation with ThreadX

•

USB host and device stacks coming with many classes: USBX

•

Advanced file system and flash memory translation layer: FileX / LevelX

•

Industrial grade networking stack: optimized for performance coming with many IoT protocols: NetX Duo

•

USB PD library

•

Open bootloader

•

Arm trusted Firmware-M (TF-M) integration solution

•

MCU boot

•

Mbed Crypto libraries

•

STMicroelectronics network library

•

STMTouch touch sensing library solution.

Several applications and demonstrations implementing all these middleware components are also provided in the

STM32CubeU5 MCU package.

The STM32CubeU5 MCU package component layout is illustrated in Figure 1.
