Helping system manufacturers to address advanced security needs for connected devices in industrial automation, building automation, and smart metering systems, Renesas has added new MCUs in its popular RX65N/RX651 microcontrollers series.
Key features of the new RX65N/RX651 MCUs include an Integrated Trusted Secure IP to realize high root-of-trust levels for device operation, network connectivity and HMI features optimized for the IIoT, and seamless in-the-field firmware updates.
“With more devices at the edge of the IIoT, there’s an increasing need for secure network connectivity and reliability, including secure on-the-go firmware updates. The expanded RX65N/RX651 devices support these evolving security and re-programmability needs, offering integrated Trusted Secure IP, enhanced flash protection, and other technological advancements to create a secure and stable integrated solution far above others in the market, as proven by the Cryptographic Algorithm Validation (CAVP) certification”, according to Renesas.
The new MCUs are based on the high-performance RXv2 core and a 40nm process, which provide strong power efficiency for CPU operation at 4.55 Core Mark/MHz, claimed the firm.
With network connectivity and HMI support, the MCUs make it possible for engineers to monitor the operating state of machinery from both inside and outside the factory, exchange data for making changes to production instructions, and reprogram the MCU’s memory to update equipment settings.
An embedded TFT controller and an integrated 2D graphics accelerator inside the MCUs provide advanced graphics features for controlling small TFT displays required to monitor machine behavior in IIoT applications.
Selecting a WQVGA display size, Renesas claims, allows the large 640 KB of on-chip RAM to be used as display frame buffer, which saves external RAM, ensuring a cost-optimized design.
Supporting secure and reliable in-the-field firmware updates required in industrial IoT applications, the new RX65N/RX651 MCUs feature dual bank flash integration supporting both BGO (Back Ground Operation) and the SWAP function.
Renesas’s new Envision Kit provides an evaluation environment that allows engineers to easily benchmark MCU performance and start developing their own software.
The new RX65N Renesas Starter Kit (RSK) includes a development board with MCU, display, on-chip debugger, trial Renesas C compiler and Integrated Development Environment (IDE), enabling engineers to develop within a matter of minutes.
The expanded RX65N/RX651 MCUs, Renesas RX65N Starter Kit, and Envision Kit are available now.
