Promotional Board for RX62N

  • Overview

The Renesas Promotional Kit (RPB) for RX62N has been designed to enable the user to quickly investigate the performance of the RX62N device family.

Based on an embedded web server, a number of mini demonstration applications can be used to showcase the Ethernet controller, USB function and Floating Point Unit (FPU) found on the RX62N. Further investigation of the device and available RX development tools can be completed using the on-board Segger J-Link JTAG debugger and High-performance Embedded Workshop (HEW) IDE.

When combined with the 60 day (then 128K) evaluation Renesas compiler and full source code of the web server and mini applications the RPB makes an ideal introductory platform for RX62N device family.

The RPB pack contains everything the user needs to install and get going within minutes of opening it, there is no need to download anything from the web!

The RPBRX62N first released at Electronica 2010 and is now available through Renesas sales channels.

RPBRX62N pack

Kit contents

The RPBRX62N blister-pack contains:

  • RPBRX62N board
  • RPBRX62N 8cm mini-CD containing evaluation software, sample software and the documentation suite (including the Quick Start Guide) - also downloadable from here
  • Ethernet cable
  • USB cable
  • Potentiometer shaft

ZIP file, 145 MB. The file contains a .iso CD image which can be used to burn your own RPB CD.

The RPB Board

The RPB Board is shown here, everything you need to interact with the RX62N. The Segger debugger is built onto the rear of the PCB providing a complete Evaluation platform in one small package.



The board is pre-programmed with self-installing drivers and a demonstration website showing the capabilities of the RX/600 CPU.

Connection is simple, the user connects the Ethernet cable to their Hub (or direct to the laptop or PC), connects via USB to a spare port on their PC or laptop.

The setup procedure enables the user to connect with the board using a normal web browser. Once connected the user can see a number of demos including some basic functions:

  • Control the on-board LEDs from the browser
  • Measure performance of the device

Plus more advanced functions using a VNC client (e.g. the one at

  • Human Interface Device (mouse) demo using on-board joystick (SW2) and buttons
  • Dhrystone benchmark demo
  • Bouncing ball demo (FPU ball vs. non-FPU ball)



  • Mandelbrot demo*



    * This demo features the ability to explore the Mandelbrot Set, named after the late Dr. Benoît Mandelbrot, and first visualized by Brooks and Matelski in 1978.

    The fractal boundary of the Set obeys the equation: zn+1 = zn2 + c.

    "A cloud is made of billows upon billows upon billows that look like clouds. As you come closer to a cloud you don't get something smooth, but irregularities at a smaller scale."

    - Benoît Mandelbrot, 1924-2010 (Bio)

  • Pong! game demo

Running the Demo

This requires the user to connect to the RPB via the supplied Ethernet cable and via a USB connection, this is fairly straightforward but can be dependent upon the User's network settings. The Quick Start Guide is designed to cater for the most common settings but it is not possible to cover all possibilities in the Guide without making it overly complicated!

Here are some hints and tips when running the Demo:

  • The full Quick Start Guide can be found on the CD, the one on the back of the pack is relevant if you know you have DHCP and .NET installed only.
  • The CD has a .NET web installer executable in the Root folder
    • Installation requires an Internet connection
  • The Demo is not guaranteed to work under Win7, however the development tools supplied (Evaluation RX compiler and HEW IDE) are Win7 compatible.
  • Connecting the RPB to your network, then to your PC via USB may result in an easier connection than connecting directly to your PC's Ethernet port as many companies have protection software installed on their PCs which may make such connections difficult.
  • When connecting the Ethernet cable, you should see LEDs flashing on the Ethernet socket AND also the FDUPLEX and SPEED LEDs
    • If there is no activity, check the Ethernet cable connection, nothe that if using a different cable than the one supplied the RPB can connect with either a 1:1 or crossover

Evaluation Compiler

The RPBRX62N is supplied with an Evaluation license for Renesas RX C/C++ compiler. This will give the user full functionality for 60-days from first installation. Once expired the license will reduce to a limitation of 128kB linked object size.

If you have previously evaluated the RX compiler and require an additional evaluation time for the RPB, please apply to your Renesas sales contact or distributor agent.

Renesas Peripheral Driver Library (RPDL)

The Renesas Peripheral Driver Library (RPDL) is a unified API for controlling the peripheral modules on the microcontrollers made by Renesas Electronics.

A pre-release version of the Library API is utilized in the sample code for the RPB, but the manual was not included on the disk so we have made it available online - click here to download.


If you have problems getting the demo to work, try the following hints.

  1. CD does not work automatically - Use Windows Explorer to browse the CD and run setup.exe
  2. Cannot connect to the Demo (page not found error)
    • Check the ethernet connection, are the LEDs on the ethernet connector and the FDUPLEX and SPEED LEDs illuminated? If not puch connector in or change Ethernet cable.
    • Check the IP address is correct (use the "Launch Broswer" button on the Viewer application to start the demo).
    • If connecting directly to the board from the PC's ethernet port, check you have correctly set up the PC's IO address, Subnet mask and Gateway, not the info above on this page about the displayed advised IP address being incorrect.
    • Check your machine's firewall and other protection software to see that access to the board is not being blocked (you may need to contact your company's IT department).
  3. Can use some demos but not others
    • Check that you have installed a valid VNC client and that it is configured according to the instructions.
    • If you have used the Human Interface Device (HID) demo, make sure you switch it off before proceeding to the other demos
  4. I have reprogrammed the board but want to reinstate the demo
    • Just create a Tutorial Project in the High-performance Embedded Workshop, build and download it to the board. The Tutorial project is in fact the demo project. See Quick Start Guide for details.
  5. I cannot build the Tutorial project
    • Check the the compiler Evaluation License has not expired (the status can be seen either in the Output pane of the HEW Window, or you can view the license status in Help > Technical Support > License Management > [Report]).
  6. I lost my cables, can I use any USB or ethernet cable?
    • Yes
  7. I am using Japanese language Windows and the installer does not work.
    • The installer is designed for the European and North American markets, Japanese language support was not included due to the restricted space availability on the mini-CD. We are looking to include Japanese support at version 3, due January 2011.

Version History

Version 01 of the CD (released at Electronica 2010 showing the reference D010048_25_V01) contained two of minor errors described here. These have been addressed in version 2 (shipping from 30 Nov 2010). Reference D010048_25_V02 is version 2.

Version 1 Corrections

When connecting the ethernet directly to a PC (not via a company network), the USBViewer application reports the following:

The recommended setting for the PC shown is not correct, the IP address should be (or any other integer from 1-9). If you enter a zero as part of the IP address then Windows will report an error, also this IP address has to be different from the default one on the RPB which is

Other information:

  • The FDUPLEX and SPEED LEDs are incorrectly referenced in the Quick Start Guide as LED3 and LED4

Version 2 Corrections

No known errors.
