The RX13T 32-bit microcontroller (MCU) is perfect for optimized single motor control applications used to drive vector control/field-oriented control (FOC) of a permanent magnet synchronous motor (brushless DC motor). The RX13T features a best-in-class built-in floating point unit (FPU) at 32MHz and various built-in peripheral functions, making for a compact and low BOM cost single motor control board. This design demonstrates a standard DC input (24V) and utilizes the axial position sensor, allowing motor axle position feedback without HALL effect sensors.

System Benefits​:

  • Shows a discrete integration of high voltage/current MOSFETs
  • Features a rotational sensor, a highly integrated contactless sensing device
  • Supports a wide range of motor capabilities, from 12V up to 36V, max 4A (144W) 
  • Offers simple interfacing to external control hardware (ADC input, PWM input)




  • Flight and car simulators for gaming (steering wheel, speed/brake pedals) and RC cars.
