Renesas Electronics Corporation has introduced the RX66T microcontroller (MCU) group, the first members of the 32-bit RX MCU family based on a new third-generation RXv3 CPU core. The new MCUs leverage cutting-edge CPU technology to achieve improved performance, up to 2.5 times better than previous RX family MCUs. When operating at 160 MHz, the RX66T MCUs achieve best-in-class performance of 928 CoreMark®2, enabling more precise inverter control. These MCUs can control up to four motors simultaneously, making them ideal for conventional motor control and applications requiring multi-axis motor control, such as compact industrial robots and personal robots. Furthermore, the RX66T's additional processing power allows developers to add programs that utilize embedded AI (e-AI) for motor fault detection. These programs can detect motor faults and pinpoint the fault location in real time based on the motor's vibration or current characteristics. Providing this capability offers developers significant added value in terms of productivity, safety, and quality. The RX66T MCUs also integrate a 5V power supply that provides excellent noise tolerance.
With more and more devices—from robots and power conditioners to washing machines and dryers—joining the Internet of Things, motorized devices in the field will require online firmware updates throughout their lifecycles. The application of e-AI for predictive fault diagnosis requires endpoint MCUs to be securely updated with learning outcomes generated in the cloud. The RX66T MCU cluster incorporates Renesas' Secure and Reliable IP (TSIP), which has a CAVP3 certification track record and provides secure firmware updates and encrypted communication.
