Ultra low-power MCU'er til mere sikre IoT-applikationer

STMicroelectronics lancerer STM32L5, der er ultra low-power microcontrollere, der inkluderer Arm TrustZone hardware-baseret cyber beskyttelse (in english).

STMicroelectronics (ST) is bringing sophisticated cyber-protection to power-conscious connected devices with the new STM32L5 microcontroller (MCU) series featuring the Arm Cortex-M33 core.

Building on the Cortex-M33, which boosts protection for small devices by integrating Arm’s TrustZone hardware-based security, ST’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. Consuming as little as 33nA in shutdown mode and achieving 402 ULPMark-CP in the EEMBC ULPBench, the new MCU series builds on the Company’s expertise in low-power techniques such as adaptive voltage scaling, real-time acceleration, power gating, and multiple reduced-power operating modes proven in previous STM32L series.

- The STM32L5 series with TrustZone and additional custom protection features considerably strengthens and hardens cyber-protection for small IoT devices, says Ricardo De Sa Earp, Microcontroller Division General Manager, STMicroelectronics.

- 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.
With extensive integrated digital and analog peripherals, and consumer and industrial interfaces such as CAN FD , USB Type-C, and USB Power Delivery, STM32L5 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.

ST unveiled the STM32L5 series MCUs in a demonstration, created in collaboration with security-software specialist Prove & Run at the Arm TechCon conference in San Jose, California.

- IoT devices are increasing in intelligence and functionality, and security needs to be built in from the ground up, says 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, adds:

-  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.
