In addition, with the emergence of AI-based needs, Renesas is excited to complement Google’s TensorFlow Lite supported platforms with the RA6T1 motor control and predictive maintenance solution.” “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.

spikes down to -120V, which enhances the reliability of power tools. Featuring on-board bus voltage sensing, the STEVAL-PTOOL2V1 board measures 77mm x 54mm. The power stage features the ST Power MOSFET N-channel, 80V, STripFET F7 technology. Both boards provide a potentiometer for speed variation, inputs for trigger and rotation-direction setting, thermal shutdown, and protection against reverse biasing of power- stage outputs. They are supplied with a heatsink already mounted. In addition to cordless tools, the boards can be used in any battery-operated applications that utilize brushless 3-phase motors with single-shunt control. The STEVAL-PTOOL1V1, priced at $41.00, and STEVAL- PTOOL2V1, $69.00, are available now. The STSW-PTOOL1 firmware for STEVAL-PTOOL1V1 and STSW-PTOOL2 for STEVAL-PTOOL2V1 can be downloaded free of charge from www.st.com/stspin-pr * STM32 is a registered and/or unregistered trademark of STMicroelectronics International NV or its affiliates in the EU and/or elsewhere.
