STMicroelectronics STM32 Cube ecosystem with Microsoft Azure RTOS

Click2Contact

STMicroelectronics has signed an agreement with Microsoft to simplify and accelerate the development of smart-appliance controllers and other IoT devices. Developers working with STM32 microcontrollers (MCU) can now leverage Microsoft Azure RTOS (Real-Time Operating System) to provide ready-to-use services for managing their application.

Seamlessly connected to the STM32Cube development ecosystem, which consolidates tools and software to support customers’ projects from start to finish, Microsoft Azure RTOS will be fully supported and all licences are free for images deployed properly on STM32 microcontrollers, including prototyping and volume production. Azure RTOS accessed through the STM32Cube tools integrates seamlessly with the Azure IoT platform, providing an easy and convenient means of connecting IoT endpoints and edge devices to the cloud.

The STM32Cube ecosystem provides free development tools, software bricks and software expansion packages for users to handle everything from selecting the right device and initialising the project to coding, programming, testing, and scaling and porting the design if needed. The ecosystem also features a broad offering of embedded software libraries. The user can pick and choose in a portfolio of more than 100 software packages from ST and partners, now enriched with Azure RTOS to further accelerate development of the final application.

The collaboration between ST and Microsoft lets users leverage the rich services of Azure RTOS, which meet the needs of tiny, smart, connected devices. This includes the Azure RTOS ThreadX real-time operating system, which has a compact memory footprint suited to deeply embedded applications. Also included are the FileX FAT file system, NetX and NetX Duo TCP/IP networking stacks, and USBX USB stack.

Value-added features of the Azure RTOS middleware components include support for IP layer security (IPsec) and socket layer security (TLS and DTLS) protocols, with future Common Criteria (CC) EAL4+ certification for TLS/DTLS and FIPS 140-2 certified software cryptographic library. Microsoft will also provide safety pre-certifications including IEC 61508 SIL4, IEC 62304 Class C and ISO 26262 ASIL-D.

While ensuring a consistent look and feel across Azure RTOS components and products, which promotes ease of use, Microsoft is also providing extra flexibility for embedded developers by publishing the source code at GitHub as part of the agreement with MCU vendors.
