The new MCUs offer up to 2.5 times improved performance over previous RX family MCUs. Combining the new RXv3 core with the capabilities of Renesas’ RX62T and RX63T MCUs, the new RX66T MCUs provide the real-time performance and stability required by inverter control applications.

RX66T MCUs operating at 160 MHz achieve a CoreMark performance of 928, which is market leading according to Renesas. The MCUs have the capability to control up to four motors simultaneously, making them ideal for conventional motor control and applications requiring multi-axis motor control. In addition, the additional processing capacity allows developers to add programs utilizing embedded AI (e-AI) for motor fault detection. Such programs can to detect motor faults and identify fault location in real time based on the motor’s current or vibration characteristics. RX66T MCUs also use a 5V power supply that delivers excellent noise tolerance.

The application of e-AI for predictive failure diagnostics requires endpoint MCUs to be securely updated with learning results generated in the cloud. For secure updates and encrypted communications, the RX66T MCU range uses Renesas’ Trusted Secure IP (TSIP), which has CAVP certification.

The new MCU range is supported by Renesas Motor Workbench 2.0, which offers 20kHz real-time debugging and adds 10 new functions and an RX66T CPU card for the 24V Motor Control Evaluation Kit.
