Advanced software for the STM32H5 MCUs utilizes the company’s Secure Manager to ensure a safeguarded link to the cloud-based IoT platform.

STMicroelectronics has launched software that streamlines the integration of Internet of Things (IoT) devices, developed with the advanced STM32H5 microcontrollers (MCUs), to the Microsoft Azure IoT Hub. The STM32Cube expansion package from the company termed X-CUBE-AZURE-H5 includes libraries and sample applications for the new series of microcontrollers, functioning as end devices. 

It has a ready-to-run firmware example that leverages both Ethernet and Wi-Fi connectivity. This is designed to expedite the evaluation and development of Microsoft Azure cloud-connected applications built on the latest series of microcontrollers. It has TLS encryption, and Wi-Fi and Azure connection credentials are securely housed within the storage protected by the secure manager. Prebuilt binaries are provided for added convenience and immediate deployment, ensuring a swift connection.

Main features include:

  • Offers up to 2 Mbytes of dual-bank flash memory.
  • Provides up to 640 Kbytes of SRAM.
  •  Features high peripheral integration.
  • Portfolio has a wide package range: 25- to 176-pin.
  • Supports ambient temperatures up to 125°C.
  • Suitable for harsh environments.

The demonstration application highlights secure connectivity from the device to Azure IoT Hub, encompassing network setup and data transmission. It manages Azure messages, methods, and twin update commands.  It has processor architecture and heightened security. Developers can harness the features of the Azure IoT Hub through the new cube. This helps them to convert device data into actionable knowledge, paving the way for educated choices, refined operations, and enhanced offerings. With the advanced security provisions of the chip, developers find it easier to set up and oversee high-performing IoT gadgets securely. This guarantees a secure link from the device to the Azure IoT Hub.

Secure Manager offers isolation features that aid in safeguarding the intellectual property of several owners on a shared platform, often called multitenant IP protection. From the design phase to production and field deployment, it ensures the protection of the confidentiality and integrity of vital assets contributed by developers and partners. This is particularly effective for scenarios that incorporate AI inference. In such cases, models operate on edge devices under the shield of a secure manager. 

The fusion of microcontrollers equips developers with a robust and secure foundation for crafting IoT applications that are compliant with relevant regulations and standards.
