STMicroelectronics unveils Microcontrollers for a more Secured IoT

STMicroelectronics (STM) is bringing sophisticated cyber-protection to power-conscious connected devices. Its new STM32L5 microcontroller (MCU) series features the Arm Cortex-M33 core. The Cortex-M33 boosts protection for small devices by integrating Arm’s TrustZone hardware-based security.
STM’s STM32L5-series MCUs add further enhancements including flexible software isolation, secure boot, key storage, and hardware cryptographic accelerators. They also provide rich functionality, high performance, and long run-times powered by coin cells or energy harvesting.

STM-proprietary ultra-low-power technologies create class-leading MCU for energy-conscious applications.

“The STM32L5 series with TrustZone and additional custom protection features considerably strengthens and hardens cyber-protection for small IoT devices. Also featuring our unique energy-saving technologies, rich connectivity, and smart digital and analog peripherals, these devices will be the first choice to host cutting-edge connected applications,” said Ricardo De Sa Earp, Microcontroller Division General Manager, STMicroelectronics.

STM32L5 MCUs are equipped with extensive integrated digital and analog peripherals, and consumer and industrial interfaces such as CAN FD, USB Type-C, and USB Power Delivery. These new MCUs provide an ideal platform for products such as industrial sensors or controls, home-automation devices, smart meters, fitness trackers, smart watches, medical pumps or meters, and many others.
STM32L5-series microcontrollers are sampling now and scheduled to begin production in Q2 2019.
“IoT devices are increasing in intelligence and functionality, and security needs to be built in from the ground up,” said John Ronco, vice president and general manager, Embedded & Automotive Line of Business, Arm. “Arm’s Platform Security Architecture (PSA), a common framework for security implementation, aims to put security at the heart of IoT. The STM32L5 series makes it easier for developers to build trusted devices on the PSA framework with the Cortex-M33 processor, TrustZone technology and enhanced SoC security features.”
Dominique Bolignano, President & Founder of Prove & Run, provider of the ProvenCore-M secure RTOS, said, “Working with ST to prepare the demonstration, we clearly see how to leverage STM32L5 hardware features to increase the protection needed for connected devices to handle the latest cyber threats.”
The STM32L5 series is available in standard temperature grade for consumer and commercial applications, or high-temperature grade specified from -40°C to 125°C for challenging environments.
