Overview

---

MCB-RX14T is a motor control evaluation kit. By using this product, motor control with MCK-RX14T can be performed easily.

MCK-RX14T has characteristics shown below

• Supports Brushless DC motor.
• Supports 1-/2-/3-shunt current detection.
• Supports Motor Control Development Support Tool (Renesas Motor Workbench).
• Provides overcurrent protection function using overcurrent detection circuit.

The key features of the MCB-RX14T are categorized in two groups (consistent with the architecture of the board) as follows:

MCU Native Pin Access

The MCB-RX14T includes:

• R5F514T5AMFM MCU (referred to as RX MCU)

  • Max 48 MHz, 32-bit RX CPU (RXv2)
  • 128 KB ROM, 12 KB RAM
  • 64-pin, LFQFP package

System Control and Ecosystem Access

• DC 5V,3.3V (selectable with jumper pin) input sources

• Select one way automatically from the below

  • Power is supplied from compatible inverter board
  • Power is supplied from USB connector

• E2OB (Onboard debugger circuit)

• User LEDs and switches

  • 5 User LEDs
  • Power LED indicating availability of regulated power
  • MCU reset switch

• Connectors

  • Inverter board connector
  • USB connector for E2OB
  • SCI connector for Renesas Motor Workbench communication
  • Through hole for SPI communication
  • Pmod connectors

Programming and Debugging

---

.. zephyr:board-supported-runners::

Applications for the mcb_rx14t board can be built, flashed, and debugged using standard Zephyr workflows. Refer to :ref:build_an_application and :ref:application_run for more details.

Flashing

The program can be flashed to MCB-RX14T using the E2 Lite debugger by connecting the board's 14-pin debug connector to the host PC. Here’s an example for building and flashing the :zephyr:code-sample:hello_world application.
