STMicroelectronics Intros Low-Power Microcontrollers for Secure IoT Applications

STMicroelectronics, a global semiconductor company, is providing cyber-protection for connected devices with its new STM32L5 microcontroller (MCU) series. The MCU features Arm's Cortex-M33 core, which is designed to boost protection for small devices by integrating Arm's TrustZone hardware-based security system.

The STM32L5-series MCUs include flexible software isolation, secure booting, key storage and hardware cryptographic accelerators. "The STM32L5 series with TrustZone and additional custom protection features considerably strengthens and hardens cyber-protection for small IoT devices," said Ricardo De Sa Earp, STMicroelectronics' microcontroller division general manager, in a prepared statement. "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 integrated digital and analog peripherals, as well as consumer and industrial interfaces, the STM32L5 provides a platform for industrial sensors or controls, home-automation devices, smart meters, fitness trackers, smart watches, and medical pumps and meters. The microcontrollers are sampling now and are scheduled to enter production during the second quarter of 2019. ST unveiled the MCUs in a demonstration, created in collaboration with security software specialist Prove & Run, at Arm TechCon, held on Oct. 16-18 in San Jose, Calif.

"IoT devices are increasing in intelligence and functionality, and security needs to be built in from the ground up," said John Ronco, the VP and general manager of Arm's Embedded & Automotive Line of Business, in the prepared statement. "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."

The TrustZone IP integrated in the STM32L5 implements trusted-computing principles for authenticating devices connected to a network. First conceived for such equipment as desktops, mobile devices and communication infrastructure, this hardware-based approach blocks attempts to corrupt devices or software and creates a protected execution environment for sensitive code and cyber-protection, such as cryptography and key storage. The STM32L5 makes this protection accessible for the resource-constrained embedded systems that drive Internet of Things (IoT) devices.

STM32L5 users can include or exclude each I/O, peripheral, or area of Flash or SRAM from TrustZone protection, allowing sensitive workloads to be fully isolated for security purposes. In addition, ST has designed TrustZone to ensure support for secure booting, special read-out and write protection for integrated SRAM and Flash, and cryptographic acceleration including AES 128/256-bit key hardware acceleration, private key acceleration (PKA) and AES-128 On-The-Fly Decryption (OTFDEC), to protect external code or data. Active tamper detection and support for secure firmware install are also included.

The STM32L5 series introduces new digital peripherals, including USB Full Speed with dedicated supply, allowing customers to keep USB communication even when the system is powered at 1.8V, and a UCPD controller compliant with USB Type-C Rev. 1.2 and USB Power Delivery Rev. 3.0 specifications. Smart analog features include an analog-to-digital converter, two power-gated digital-to-analog converters, two ultra-low-power comparators, and two operational amplifiers with external or internal follower routing and programmable-gain amplifier capability. The STM32L5 is available in standard temperature grade for consumer and commercial applications, or high-temperature grade specified from -40 degrees to +125 degrees Celsius for challenging environments.
