Overview
The FPB-RA8E1, a Fast Prototyping Board for the RA8E1 MCU Group, enables users to seamlessly evaluate the features of the RA8E1 MCU group and develop embedded systems applications using Flexible Software Package (FSP) and the e2 studio IDE. Users can use on-board features along with their choice of popular ecosystems add-ons to bring their big ideas to life.
The MCU in this series incorporates a high-performance Arm® Cortex®-M85 core with HeliumTMrunning up to 360 MHz with the following features:
The following components are included in the FPB-RA8E1 box:
The specifications of the CPU board are shown below:
MCU specifications

ROM/SRAM size: 1MB/512KB
MCU input clock: 20MHz (Generate with external crystal oscillator)
Power supply: DC 5V, select one way automatically from the below:
Connector
Onboard debugger
This product has the onboard debugger circuit, J-Link On-Board (hereinafter called “J-Link-OB”). When you write a program, connect the CPU board to PC with USB cable. J-Link-OB operates as debugger equivalent to J-Link. If connecting from flash programming tool (e.g. J-Flash Lite by SEGGER), set the type of debugger (tool) to “JLink”
Hardware
Detailed Hardware features for the RA8E1 MCU group can be found at:
RA8E1 Group User's Manual Hardware_FPB-RA8E1 - User's Manual_.. zephyr:board-supported-hw::
Programming and Debugging
.. zephyr:board-supported-runners::
Applications for the fpb_ra8e1 board can be built, flashed, and debugged in the usual way. See
:ref:build_an_application and :ref:application_run for more details on building and running.
The FPB-RA8E1 board includes an on-board SEGGER J-Link debugger. SEGGER J-Link drivers are available at https://www.segger.com/downloads/jlink
To use the on-board J-Link debugger, ensure that:
The J-Link OB is connected to the host PC via the USB port (J10).
The J-Link OB jumper is in the default configuration as described in the FPB-RA8E1 - User's Manual_.
Connect a USB cable from your PC to the on-board virtual COM port (J10), and use a serial terminal of your choice (minicom, PuTTY, etc.) with the following settings:
Here is an example for the :zephyr:code-sample:hello_world application.
.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: fpb_ra8e1 :goals: flash
Open a serial terminal, reset the board (push the reset switch S2), and you should see the following message in the terminal:
.. code-block:: console
***** Booting Zephyr OS v4.3.0-xxx-xxxxxxxxxxxxx ***** Hello World! fpb_ra8e1
Here is an example for the :zephyr:code-sample:hello_world application.
.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: fpb_ra8e1 :goals: debug
Open a serial terminal, step through the application in your debugger, and you should see the following message in the terminal:
.. code-block:: console
***** Booting Zephyr OS v4.3.0-xxx-xxxxxxxxxxxxx ***** Hello World! fpb_ra8e1
