INVESTMENT AND BUSINESS
STMicroelectronics | May 13, 2022
STMicroelectronics has created a new AWS FreeRTOS-qualified, TF-M-based reference implementation, working in conjunction with Amazon Web Services (AWS), an ST Authorized partner, to easily and securely connect Internet of Things (IoT) devices to the AWS cloud.
“FreeRTOS, backed by our long-term support libraries, is the perfect platform for connecting resource-constrained devices to powerful cloud services,” said Dave Kranzler, GM, IoT Devices, AWS. “Working with ST to integrate industry-standard Arm open-source secure TF-M software and the STM32U5 MCU’s security features lets developers quickly build edge-to-cloud solutions that resist cyber threats.”
The superior security built into our STM32U5 MCUs supports the creation of trusted IoT devices to connect to the AWS cloud. Our qualified reference platform represents a significant investment in software integration that saves development time and costs while simplifying compliance with PSA Certified security guidelines.”
Daniel Colonna, Marketing Director, Microcontroller Division, STMicroelectronics.
The jointly created solution combines ST’s STM32U5 ultra-low-power microcontrollers (MCUs), FreeRTOS open-source real-time operating system, and Arm trusted-firmware for embedded systems (TF-M). The reference implementation is realized on ST’s B-U585I-IOT02A discovery kit for IoT nodes with STM32U5 MCUs, which contains rich features including USB, Wi-Fi, and Bluetooth Low Energy connectivity, as well as multiple sensors. The STSAFE-A110 secure element support is being added and comes pre-loaded with IoT object credentials. It helps secure and simplifies attachment between the connected objects and the AWS cloud.
FreeRTOS comprises a kernel optimized for resource-constrained embedded systems and software libraries for connecting various types of IoT endpoints to the AWS cloud or other edge devices. AWS’s long-term support (LTS) is maintained on FreeRTOS releases for two years, which provides developers with a stable platform for deploying and maintaining their IoT devices.
The Arm TF-M firmware simplifies protecting embedded systems, including services for secure boot, secure storage, cryptography, and attestation, forming the basis of a trusted execution environment (TEE) on the device. Designed for Arm v8-M architectures, TF-M integrates readily with TrustZone on ST’s STM32U5 MCUs, which feature the Arm Cortex-M33 core.
ST’s STM32U5 MCUs target demanding IoT-edge applications, featuring the advanced 160MHz Cortex-M33 core with Arm TrustZone technology and Armv8-M mainline security extension, up to 2MB on-chip Flash, and extreme power-saving features. With hardware cryptographic accelerators, secure firmware installation and update, and enhanced resistance to physical attacks, the MCUs have achieved PSA Certified Level-3 and SESIP 3 certifications. Also, their extreme energy-saving design simplifies powering the application and extends battery lifetime in remote applications. Highlights include three different stop modes that maximize opportunities to operate at the lowest possible power and ST’s batch-acquisition mode that captures peripheral data even while the core is powered down.
The STSAFE-A110 EAL5+ certified secure element brings an authentication scheme and personalization service that allow an automated and secured attachment of connected objects to the AWS cloud. It safely relieves the historical burden on IoT-device makers to protect secret credentials during product manufacture.
ST will release a version of the reference implementation based on STM32Cube tools and software in Q3 this year, which will further simplify IoT design leveraging seamless integration with the rest of the STM32 ecosystem.

Digi International | May 24, 2022
Digi International, a leading global provider of Internet of Things (IoT) connectivity products and services, today introduced the Digi XBee® Intelligent Edge controller (IEC), bringing together a comprehensive networking architecture to close the gap between field devices and the cloud and provide powerful asset monitoring and control.
Digi XBee Intelligent Edge Controller (IEC) provides a deployment-ready upgrade to existing industrial sensors with the latest innovations in wireless and cloud technologies. In combination with Digi X-ON cloud, the Digi XBee IEC can help companies monitor sensors or remote-control assets over Long-Range, Low-Power Wide Area Networks, including LoRaWAN, CAT-M1 and NB-IoT. Industrial devices can be monitored with sub-second latency with alarms and data wirelessly delivered through the Digi X-ON cloud.
The Digi XBee IEC is compatible with 90% of existing industrial sensors and controls, providing SCADA systems with an IoT alternative. The solution is ideal for enterprises across numerous industry verticals such as energy and utilities, oil and gas, water and wastewater, logistics and agriculture. Using Digi’s X-ON cloud platform, customers leverage a single solution to convert complex protocols for the industrial IoT into simplified data APIs, to integrate data with other tools and systems.
“Two of the biggest challenges companies face in industrial IoT projects are money and time,” said Nik Kitson, Director of OEM Solutions Business Development for Digi. “Traditional SCADA systems are very expensive and can take months to deploy and configure for a company's specific needs. A new system or software package often involves a substantial learning curve and employee training time. But remaining with a non-secure or outdated system can cost far more in the long run. Unlike legacy systems that could only leverage the tools available at the time, Digi developed the IEC using today’s most advanced technologies to create more intelligent, secure, and cost-effective solutions.”
A Smarter Alternative to Traditional SCADA
Traditional SCADA systems have typically relied on extensive middleware – including gateways, software, and licenses – raising the risk of unauthorized data accessibility and other security breaches. Industrial IoT protocols add security as an afterthought and require users to enable those features. The combination of complex technology infrastructures, communications interoperability challenges, and immature IoT standards creates enormous hurdles for automation engineers. Additionally, standard SCADA and PLCs often require high network bandwidth and cloud capacity to provide sub-second monitoring.
The Digi XBee IEC solution is being successfully deployed for electrical smart-grid asset monitoring, smart city water management, logistics warehouse operations, and more.
“The Digi solution enables Valmont to offer a proactive condition monitoring experience that complements our scheduled maintenance and operations. The ability to detect infrastructure anomalies in real time using remote wireless technology unlocks huge potential, enabling our customers to operate tower infrastructure without over-taxing remote operations workers.”
Trevor Mecham, Vice President of Global Infrastructure Technology Strategy and Industry Relations at Valmont Industries, Inc
Digi XBee IEC not only provides a faster time-to-market for IIoT OEMs and enterprises, it is also a value-added tool set for systems integrators and Value Added Resellers (VARs) to address complex IIoT deployments. The IEC solution can be easily deployed into multiple solutions for a wide range of use cases, all through the X-ON device management portal.
