Arm Cortex-M4-based MCU rich peripherals reduce motor control BOM cost and supports predictive maintenance solution with Google’s TensorFlow Lite for microcontrollers...
Renesas Electronics announced the extension of its microcontroller (MCU) portfolio designed for motor control applications targeting smart homes, industrial automation, and building automation.
Featuring a rich set of peripheral functions and AI-based failure detection, the four new RA6T1 Group MCUs are the latest members of Renesas’ rapidly expanding Arm-based RA Family, and the first RA MCUs designed for the unique needs of motor control in home appliances, HVAC, solar inverters, and AC drives.
“AI and machine learning are taking predictive maintenance to the next level as the industry advances toward Maintenance 4.0. We are excited to join forces with Renesas and accelerate the adoption of smart home and Industrial IoT applications,” said Ian Nappier, Product Manager at Google. “Integrating our open-source TensorFlow AI framework with Renesas’ powerful RA6T1 MCUs brings breakthrough intelligence to motor control equipment.”
Based on the Arm Cortex-M4 core, the new RA6T1 32-bit MCUs operate at 120 MHz and feature a rich collection of peripherals optimized for high performance and precision motor control. The integrated peripheral functions with high-speed analog significantly reduce bill of materials (BOM) cost while boosting motor control performance. For example, a single RA6T1 MCU can simultaneously control up to two brushless DC (BLDC) motors. In addition, the Google TensorFlow™ Lite Micro framework for TinyML applications adds enhanced failure detection to the RA6T1 MCUs, offering customers an intelligent, easy-to-use, and cost-effective sensorless motor system for predictive maintenance. The TensorFlow AI framework detects potentially detrimental anomalies in motor systems earlier and more accurately to help customers improve their predictive maintenance processes and reduce maintenance costs.
Renesas also offers a new Renesas Solution Starter Kit (RSSK) for developers working on a motor control solution using the RA6T1 MCUs. The RSSK offers easy motor control debugging and allows customers to immediately begin evaluating their motor control design, executing real-time analysis and tuning to accelerate development.
The easy-to-use motor solution includes an RA6T1 CPU card and 48V-compatible inverter board, along with a GUI tool for motor workbench, and a sensorless vector control sample program with three-shunt method that corresponds with the Flexible Software Package (FSP). Using the RA Family FSP makes it easy for customers to port the sample code to their program.
