STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has released a powerful new software product for its STM32H5 MCUs that leverages its advanced Secure Manager to secure connections to cloud IoT platforms.

ST announced on the 30th that it has released software that simplifies connecting IoT devices implemented using the latest high-performance STM32H5 microcontrollers (MCUs) to Microsoft Azure IoT Hub.

ST's STM32Cube expansion package, X-CUBE-AZURE-H5, comprises a set of libraries and application examples supporting high-performance STM32H5 series microcontrollers operating as edge devices.

The sample application demonstrates secure connectivity between Azure IoT Hub and devices-to-cloud, including network configuration and data publishing. This application processes Azureⓡ messages, methods, and twin update commands.

The solution also leverages ST's embedded security software, Secure Manager, to securely connect the STM32H5 to the Microsoft Azure cloud.

“With its advanced processor architecture and enhanced security features, ST’s STM32H5 is ready to power the next generation of IoT devices,” said Daniel Colonna, STM32 Marketing Director at STMicroelectronics. “The STM32Cube reference implementation lets developers leverage the powerful services available in Azure IoT Hub to turn data collected from devices into actionable insights that help them make informed decisions, optimize operations, and improve products and services.”

“The advanced security features of the STM32H5 chip simplify the process for developers to securely provision and manage high-performance IoT devices, and together with Azure IoT Hub, they ensure secure device-to-cloud connectivity,” said Kam VedBrat, general manager of Azure IoT at Microsoft.

STM32H5 MCUs are factory-programmed by ST to assign each MCU a unique ID. This ID is managed by the security manager, enabling simple and cost-effective registration of smart devices to Azure IoT Hub without having to keep the ID secret in the object production environment.

Credentials can be provisioned and managed remotely through third-party service providers for both in-production and field devices. The security manager stores credentials required to connect to Azure IoT Hub, as well as other device secrets and assets, within the STM32H5 MCU.

Security Manager provides isolation properties that allow multiple owners to protect their intellectual property (IP) on the same platform, also known as multitenant IP protection. It ensures the confidentiality and integrity of critical assets contributed by developers and partners, from development through manufacturing and field operations.

This also offers advantages in AI inference applications, where AI models run on edge devices protected by ST's security manager, with training and security updates performed via the cloud. The STM32Trust TEE security manager simplifies the implementation of robust security features.

ST has combined its STM32Cube ecosystem with STM32H5 microcontrollers to provide developers with a powerful and secure platform for building IoT applications that comply with relevant regulations and standards. The STM32H5 series, launched in March 2023, is the first STM32 MCU to support ST's Security Manager, targeting PSA Level 3 and SESIP3 certification.
