Overview

---

The FPB-RX14T, a Fast Prototyping Board for the RX14T MCU, enables users to seamlessly evaluate the features of the RX14T MCU and develop embedded systems applications. Users can use on-board features along with their choice of popular ecosystem add-on modules to bring their big ideas to life

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

MCU Native Pin Access

The FPB-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

• Native pin access through 2 x 32-pin breakout pin headers (not fitted)

• RX MCU current measurement point for precision current consumption measurement

• RX MCU on-chip oscillators as clock

System Control and Ecosystem Access

• Two 5 V input sources

  • USB
  • External power supply (using 2-pin header [not fitted])

• On-board debugger / programmer (E2 emulator On Board (referred as E2OB, FINE Interface))

• User LEDs and switches

  • Two User LEDs (green)
  • Power LED (green) indicating availability of regulated power
  • Debug LED (yellow) indicating the debug connection
  • One User switch
  • One Reset switch

• Two popular ecosystem expansions

  • Two Digilent Pmod (Type-2A [expanded SPI], Type-3A [expanded UART] and Type-6A [expanded I2C]) connectors
  • Arduino Uno R3 (referred to as Arduino) connector

• SCI Interface Connector (not fitted)

  • Supports UART connection
  • Supports connection with the MC-COM Renesas Flexible Motor Control Communication Board

Programming and Debugging

---

.. zephyr:board-supported-runners::

Applications for the fpb_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 FPB-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.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: fpb_rx14t :goals: build flash

Debugging

You can use Renesas Debug extension_ on Visual Studio Code for a visual debug interface. The configuration for launch.json is as below.
