The Arm Cortex-M23 processor-based RA2T1 microcontroller (MCU) group, designed for motor control systems, was unveiled by Renesas Electronics Corporation. Fans, power tools, vacuum cleaners, freezers, printers, hair dryers, and many more single-motor devices are specifically made for RA2T1 devices.
Feature Set Optimized for Motor Control
Numerous aspects of the new RA2T1 devices are intended to improve motor control performance, particularly in single-motor systems. A 3-channel S&H function that concurrently detects the 3-phase current values of Brushless DC (BLDC) motors is one of its noteworthy features.
Comparing this method to sequential measurement methods, the control accuracy is higher. Additionally, the RA2T1 MCUs include a supplementary Pulse Width Modulation (PWM) function of the timer, allowing for the automatic development of an asymmetric PWM and the insertion of dead time. Implementing control algorithms is made easier by this function’s inverter drive optimization.
Safety aspects that are essential in motor control applications are provided by the RA2T1 devices. When an overcurrent is detected, they swiftly cut off the PWM output by utilizing a high-speed comparator and a Port Output Enable function. The inverter specs can be used to choose the shutdown state.
Renesas Leadership in Embedded Processing for Motor Control
For more than 20 years, Renesas has shipped MCUs designed specifically for motor control. Every year, the company supplies more than 230 million motor control embedded processors to thousands of clients across the globe.
Renesas provides motor-control specialized devices in its 32-bit RX Family, its 16-bit RL78 MCUs, and its 64-bit RZ MPUs, in addition to other RA MCU groups.

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.
