Renesas Electronics announced the expansion of its popular RX65N/RX651 microcontroller (MCU) lineup that addresses advanced security needs for connected devices operating in industrial automation, building automation and smart metering systems.
The expanded lineup features MCUs with integrated Trusted Secure IP, and enhanced, trusted Flash functionality and human-machine interface (HMI) for industrial and network control systems.
The expansion of devices operating at the edge of the Industrial Internet of Things (IIoT) has increased system manufacturers’ need for secure network connectivity and reliability, including secure on-the-go firmware updates. The expanded RX65N/RX651 devices support these evolving security and reprogrammability needs, offering integrated Trusted Secure IP, enhanced Flash protection, and other technology advancements to create a secure and stable integrated solution, as proven by their Cryptographic Algorithm Validation Program (CAVP) certification. In turn, these security advancements enable seamless Flash firmware updates in the field through secure network communications.
The new MCUs are based on the high-performance RXv2 core and a 40 nm process, which provide strong power efficiency for CPU operation at 4,55 Core Mark/MHz. Integrating the Trusted Secure IP into the new MCUs enables system control engineers to realise high root-of-trust levels for device operation through a combination of Trusted Secure IP, integrated encryption hardware accelerators and protection of boot code.
