Renesas RA2T1 low-power Cortex-M23 MCUs target BLDC/PMSM motor applications

Renesas RA2T1 microcontroller (MCU) group

Renesas has recently launched the RA2T1 group of low-power motor control MCUs, built around a 64 MHz Arm Cortex-M23, for low-cost single-motor applications like power tools, fans, and home appliances. Designed for Brushless DC Electric Motors (BLDC) and Permanent Magnet Synchronous Motors (PMSM), the RA2T1 supports both trapezoidal and FOC control techniques, thanks to its integrated 3-channel Sample and Hold (S&H) circuits that enable accurate 3-phase current detection. It also includes PWM shutdown features and various analog and digital peripherals in compact packages as small as 4×4 mm QFN. Previously, Renesas introduced the RA8T1, also a motor control MCU based on the Cortex-M85 core with Helium instructions and DSP extensions. Ideal for AI-enhanced motor control in industrial and robotics applications. Around the same time, Infineon launched the PSOC Control C3x series, with real-time motor control and security features along with fast ADCs, high-resolution PWM, and PSA Level 2 compliance. Renesas […]
