Renesas expands its RX65N/RX651 line of MCUs with devices that integrate a Trusted Secure IP driver and support for HMI (human machine interface) applications. These microcontrollers are based on an RXv2 core with a maximum operating frequency of 120 MHz and provide as much as 2 Mbytes of code flash and 640 kbytes of SRAM. They also permit seamless flash firmware updates in the field through secure network communications.

Integrated Trusted Secure IP enables system control engineers to realize high root-of-trust levels for device operation through a combination of features, such as encryption-key and boot-code protection. The driver controls AES, AES-GCM, and AES-CMAC encryption and decryption, as well as the generation of random numbers through high-speed hardware calculation by the Trusted Secure IP module.

Optimized for connected industrial environments, the RX65N/RX651 MCUs make it possible 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. In addition, an embedded TFT controller and 2-D graphic accelerator allow the MCUs to control the TFT displays of industrial IoT edge devices.

Prices for the RX65N microcontroller start at about $7.58 each in lots of 1000 units.
