32-bit MCU family brings AI to motor control applications
By combining the new RXv3 core with the strengths of the current MCUs (RX62T and RX63T), the new RX66T MCUs address the real-time performance and improved stability required by inverter control. The new MCUs are ideal for use in next-generation intelligent industrial applications such as industrial motors, power conditioners and robots, as well as intelligent household appliances, including air conditioners and washing machines.
With the RX66T microcontroller group, Renesas introduces the first members of Renesas’ 32-bit RX MCU family based on the new third-generation RXv3 CPU core. The new MCUs are expected to deliver up to 2.5 times the performance of previous RX family MCUs.
By combining the powerful new RXv3 core with the strengths of the current MCUs (RX62T and RX63T), the new RX66T MCUs address the real-time performance and improved stability required by inverter controllers. The new MCUs are ideal for use in next-generation intelligent industrial applications such as industrial motors, power conditioners and robots, as well as intelligent household appliances, including air conditioners and washing machines.
Operating at 160 MHz, the RX66T MCUs achieve a performance of 928 CoreMark for more precise inverter control. The MCUs can control up to four motors simultaneously, making them ideal for conventional motor controls and applications that require multi-axis motor control, such as compact industrial robots. In addition, the additional processing capacity of the RX66T allows developers to add programs that use Embedded Artificial Intelligence; e-AI for motor fault detection. Such programs can detect motor faults and identify fault location in real time based on the motor’s current or vibration characteristics. The provision of this feature provides developers with a significant added value in terms of productivity, safety and quality. The RX66T MCUs also integrate a 5V power supply that provides excellent noise tolerance.
As more and more devices – from robots and power conditioners to washing machines and dryers – are connected to the Internet of Things, motorized devices in the field require online firmware updates throughout their lifecycle. The use of e-AI for predictive fault diagnosis requires that endpoint MCUs are securely updated with learning outcomes from the cloud. The RX66T MCU Group includes Renesas’ Trusted Secure IP (TSIP), which is CAVP certified and provides secure firmware updates and encrypted communications.
To support developers, Renesas provides its Motor Workbench 2.0 software tool, which provides 20 KHz real-time debugging, 10 new features and an RX66T CPU card for the 24 V Motor Control Evaluation Kit. It is available now.
The new RX66T group includes 80 MCUs with 64 to 144 pins and on-chip flash memory sizes from 256 KB to 1024 KB. Series production begins today for the popular 100-pin MCU packages with 256 KB or 512 KB program flash and 64 KB SRAM. Other MCU versions will be released over time.
