STMicroelectronics, a global semiconductor company serving customers across the spectrum of electronics applications, has added new software to its STM32Cube development tools that simplifies connecting high-performing Internet of Things (IoT) devices to the AWS cloud.

ST has released the X-CUBE-AWS-H5 expansion package which enables a seamless and secure connection to the AWS cloud. It contains a set of libraries and application examples designed for high-performance microcontrollers of the STM32H5 series, which act as end devices.

The solution is built on the FreeRTOS open-source real-time operating system and ST’s Secure Manager embedded security software. The recently announced STM32H5 Discovery kit is available to use with this solution and lets developers easily and securely connect their STM32H5-based prototypes to AWS IoT Core.

“The STM32H5 is ready for the next generation of IoT edge devices, bringing the performance to handle complex applications within a tight energy budget,” said Daniel Colonna, STM32 Marketing Director, STMicroelectronics. “The STM32Cube ecosystem helps developers unleash its powerful capabilities, accelerate development, and, with our latest software, connect securely to the powerful storage and data-analytics services in the AWS cloud.”

STM32H5 is one of the most powerful Arm Cortex-M33 MCU series. Devices are programmed with their own immutable identity at the ST factory. Combined with ST’s Secure Manager, this simplifies registering smart devices to AWS cloud and removes the need for costly infrastructure otherwise necessary to keep the identities of IoT objects secret during their production. 

Remote provisioning and administration of credentials will also be available via third-party service providers, during production of devices and in the field.

The isolation properties provided by Secure Manager enable the intellectual property of multiple owners to be protected. This is also known as multitenant IP protection. It is part of a comprehensive set of services that protect the confidentiality and integrity of assets belonging to STM32 developers and partners, through development, manufacturing, and in the field.

This is a perfect fit for edge AI use cases, where models are running on the edge, on devices, protected by the Secure Manager, and further trained and securely updated via the cloud. The STM32Trust TEE Secure Manager makes stronger security simpler.

Overall, the STM32Cube ecosystem with STM32H5 microcontrollers provides developers with a powerful and secure platform for developing IoT applications that comply with future regulations and standards. STM32H5, introduced in March 2023, is the first to support Secure Manager and targets PSA Certified level 3 and SESIP3 certifications.

X-CUBE-AWS-H5 is ready to download now.
