32-bit RX Microcontroller with Enhanced Analog Features Optimized for Single Motor Control


  • Optimized Functions for Single Motor Control from Timer to ADC incl. PGA and S&H
  • Built-in Data Flash and Oscillator for BOM and System Cost Reduction at 5 V Supply
  • Field Oriented Control Support Through CPU with Single-precision FPU
  • Low Pin Count Package and Reasonable Flash Size Lineup

The new Renesas RX13T microcontroller Series is specialized for single-motor control. It offers optimized analog features such as 3 channel dedicated Programmable Gain Amplifiers (PGA) and Sample and Holds (S/H) which are bypassable. The 32 MHz 32-bit RXv2 CPU Core with a single-precision Floating Point Unit enables field-oriented motor control on a state-of-the-art level. Integrated DataFlash and oscillator further reduce the BOM size and cost, while simplifying the solution. By supporting 5 V operation and TAMB up to 105 °C, the RX13T MCU is a perfect solution for demanding applications.
