MCUs power single-motor systems
With features optimized for motor control, Renesas’ RA2T1 MCUs drive fans, power tools, home appliances, and other single-motor systems. The MCUs integrate a 32-bit Arm Cortex-M23 processor running at 64 MHz and a 12-bit ADC with a 3-channel sample-and-hold function that simultaneously captures the 3-phase currents of BLDC motors for precise control.
A PWM timer supports automatic dead-time insertion and asymmetric PWM generation, features tailored for inverter drive and control algorithm implementation. Safety functions include PWM forced shutdown, SRAM parity check, ADC self-diagnosis, clock accuracy measurement, and unauthorized memory access detection.
Renesas’ Flexible Software Package (FSP) for the RA2T1 microcontroller streamlines development with middleware stacks for Azure RTOS and FreeRTOS, peripheral drivers, and connectivity, networking, and security components. It also provides reference software for AI, motor control, and cloud-based applications.
The RA2T1 series of MCUs is available now, along with the FSP software.
