IAR Systems delivers tools for ultra-low-power security MCUs from STMicroelectronics
IAR Systems has pledged immediate support for the new STMicroelectronics’ STM32L5 series in the complete development toolchain IAR Embedded Workbench for Arm as well as in the integrated security tool C-Trust for simplified security implementation.
The STM32L5 series of MCUs is based on Arm Cortex-M33 with Arm TrustZone hardware-based security. For maximum security, ST adds the freedom to include or exclude each I/O, peripheral, or area of Flash or SRAM from TrustZone protection, allowing sensitive workloads to be fully isolated.
The STM32L5 also supports active tamper detection and secure firmware installation. In addition to this protection, ST has implemented ultra-low power techniques resulting in what is described as excellent ULPMark scores, which are key measures of ultra-low power efficiency based on real-world benchmarks developed by EEMBC. Using IAR Embedded Workbench for Arm, ST has achieved the scores of 370 ULPMark-CoreProfile and 54 ULPMark-PeripheralProfile at 1.8V.
Developers using IAR Embedded Workbench for Arm can leverage advanced code optimisation techniques and power debugging functionality to make sure the application is fast, efficient and highly compact. In addition, integrated static and runtime code analysis tools ensure code quality.
Working as an extension to IAR Embedded Workbench, the security tool C-Trust enables application developers to deliver secure, encrypted code. The tool includes ready-made Security Context Profiles that automatically include all the necessary security and encryption settings for providing the application with a robust protection against intellectual property theft, malware injection, counterfeiting and overproduction. C-Trust supports the core security functions of the device, including Arm TrustZone for Arm Cortex-M.
“By combining ultra-low power with security, we are creating new possibilities for IoT applications,” says Daniel Colonna, microcontroller division marketing d, STMicroelectronics. “Our customers can leverage the extensive functionality and innovative security integration offered by IAR Systems’ tools to make sure their applications fulfill the high demands of Industrial IoT applications and other applications with requirements for reliability and security.”
Anders Holmberg chief strategy officer IAR Systems said: “Joint customers of IAR Systems and ST range from some of the world’s largest corporations to tens of thousands of small and mid-sized companies, trusting us to provide the tools they need when they need them.”
He continued: “We will continue to leverage our strong relationship to deliver superior technology and early device support, enabling our customers to take their connected products to the next level of security as well as energy efficiency.”
IAR Systems’ will be at Embedded World, Nuremberg, February 25 to 27, booth 4-140, hall 4.
