New Devices from MCU Leader Meet Demands for Performance and Compact Size; Offer Peripheral Set Targeted for Motor Control

Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced the RA2T1 microcontroller (MCU) group based on the Arm^® Cortex^®-M23 processor optimized for motor control systems. RA2T1 devices are specifically designed for single-motor applications such as fans, power tools, vacuum cleaners, refrigerators, printers, hair dryers and many more.

Feature Set Optimized for Motor Control

The new RA2T1 devices include a number of features designed to enhance motor control function, specifically in single-motor systems. One of the notable features is a 3-channel S&H function that simultaneously detects the 3-phase current values of Brushless DC (BLDC) motors. This method provides superior control accuracy as opposed to sequential measurement methods. The RA2T1 MCUs also offer complementary Pulse Width Modulation (PWM) function of the timer, which enables automatic insertion of dead time and generation of an asymmetric PWM. This function is optimized for inverter drive, which facilitates control algorithm implementation.

The RA2T1 devices offer safety features that are critical in motor control applications. They provide a Port Output Enable function and a high-speed comparator that work together to quickly shut off the PWM output when an overcurrent is detected. The shutdown state can be selected according to the inverter specifications.

Renesas Leadership in Embedded Processing for Motor Control

Renesas has shipped motor-control specific MCUs for over 20 years. The company ships over 230 million motor control embedded processors per year to thousands of customers worldwide. In addition to multiple RA MCU groups, Renesas offers motor-control specific devices in its 32-bit RX Family, its 16-bit RL78 MCUs and its 64-bit RZ MPUs.

“Customers have trusted Renesas motor control solutions for many years across thousands of systems,” said Daryl Khoo, Vice President of Embedded Processing Marketing Division at Renesas. “The RA2T1 MCUs enhance our leadership in this area with market-leading technology, low-power operation, and legendary Renesas quality and safety standards for single-motor systems.”

The new RA2T1 Group MCUs are supported by Renesas’ Flexible Software Package (FSP). The FSP enables faster application development by providing all the infrastructure software needed, including multiple RTOS, BSP, peripheral drivers, middleware, connectivity, networking, and security stacks as well as reference software to build complex AI, motor control and cloud solutions. It allows customers to integrate their own legacy code and choice of RTOS with FSP, thus providing full flexibility in application development. Using the FSP will ease migration of motor control designs to other RA Series devices.
