The STM32U5 is available to purchase as STM32U575 and STM32U575 as well as the STM32U585. In order to ensure that engineers can begin developing their applications right away, ST updated the STM32Cube ecosystem. The most notable change is that STM32CubeU5 was the very first MCU low-level package that supports Azure RTOS as a default. This makes it an emulation of the partnership that exists between ST and Microsoft we reported on last December. The software tool distinguishes its own product from other alternatives by offering a wide range of Azure Middleware for RTOS and applications examples. In addition, those wanting to run a different real-time operating system are able to download a repository through GitHub which supports different platforms. Additionally, developers using STM32CubeMX will be able to install all the relevant software directly from the user interface, which will simplify their work.

STM32U575 as well as STM32U585 The New Benchmark in Security and Efficiency

The STM32U5 first prototype was released in February. It was at the time that Twilio is a brand newly-established ST Authorized Partner, used it to unveil a new platform that greatly simplified development. The device actually enabled much higher performance, while maintaining the same level of power consumption. Also, the transition from an STM32L5 device to an STM32U5 was simple which shortened the time taken by our partner to bring their product to market. With today’s announcement that engineers can make use of the additional power to design simple user interfaces that was not possible prior to the same power envelope. Furthermore it is the STM32U5 is the first MCU to be awarded PSA Certified and SESIP Level 3 certifications. In simple terms it is the latest MCU features more powerful security features in both software and hardware which protect users and makers. Therefore, manufacturers are able to more easily obtain the highest levels of accreditation needed for specific markets like industrial, medical and other.

STM32U575 and STM32U585 An All-New Low-Power Mode, and three new development boards

The recent updates to STM32CubeU5 along with the introduction of STM32U575 and STM32U585 means that some features are now easier to access. For instance, the example code illustrates how to use the background autonomous mode that is low-power. LPBAM lets peripherals continue to function and use directly memory access (DMA) without having to wake the CPU, making the various stop modes beneficial for developers. In turn, engineers can execute the monitoring of sensors by using LPBAM by using I2C, SPI, or UART. In the same way, teams can also perform voltage monitoring using the analog-to-digital converter, or even voice activity detection through processing signals with an audio digital filter. It is interesting to note that a future upgrade to STM32CubeMX will include a graphic interface, which will further enhance the user’s experience.

To get started, teams can already grab the NUCLEO-U575ZI-Q. Engineers can use it with sensors and communication boards to build applications. Moreover, in the coming weeks, two more development boards will hit the shelves. The STM32U575I-EV evaluation kit comes with a camera module, sensors, and a display, to prototype more powerful IoT applications. On the other hand, the B-U585I-IOT02A comes with an STSAFE-A110 secure element and a Wi-Fi 4 module to focus on cloud applications. As a result, the latter platform has more MEMS and a port for the camera module. However, the daughterboard with the CMOS image sensor itself is sold separately.
