Precautions
This Renesas Demonstration Kit is only intended for use in a laboratory environment under ambient temperature and
humidity conditions. A safe separation distance should be used between this and any sensitive equipment. Its use
outside the laboratory, classroom, study area or similar such area invalidates conformity with the protection
requirements of the Electromagnetic Compatibility Directive and could lead to prosecution.
The product generates, uses, and can radiate radio frequency energy and may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment causes harmful interference to radio or television reception, which can be determined by turning the
equipment off or on, you are encouraged to try to correct the interference by one or more of the following measures:
• Ensure attached cables do not lie across the equipment
• Reorient the receiving antenna
• Increase the distance between the equipment and the receiver
• Connect the equipment into an outlet on a circuit different from that which the receiver is connected
• Power down the equipment when not is use
• Consult the dealer or an experienced radio/TV technician for help NOTE: It is recommended that wherever
possible shielded interface cables be used.
The product is potentially susceptible to certain EMC phenomena. To mitigate against them it is recommended that the
following measures be undertaken:
• The user is advised that mobile phones should not be used within 10m of the product when in use.
• The user is advised to take ESD precautions when handling the equipment.
The Renesas Demonstration Kit does not represent an ideal reference design for an end product and does not fulfill the
regulatory standards for an end product.

Chapter 2. Purpose
This RDK is an evaluation and demonstration tool for Renesas RX62N microcontrollers. The goal is to provide the user
with a powerful debug and demonstration platform targeted at common applications. A set of human/machine interfaces
are tightly integrated with the features of the RX62N and the software demonstration programs providing the user with an
accessible platform to rapidly evaluate and customize.
Target Applications and Features:
• Audio
o Stereo audio driver connected to the PWM interface
o On-board microphone to demonstrate sampling, FFT/FPU capabilities
o Volume Control Potentiometer
o Micro SD card interface for audio and data files
• Motor Control
o 3 – Phase motor control algorithm representation with LEDs
o Motor control algorithm speed variation through volume control potentiometer
• Gaming
o 3 – Axis Accelerometer (Digital)
o User pushbutton switches
o Develop and submit your sample programs to demonstrate these features to the online community:
www.RenesasRulz.com/RX62N
• Communications
o 10/100 Ethernet Interface connected to an internal Ethernet MAC (1588 compatible)
o USB Interface connected to an internal USB controller (Host, Device and OTG)
o RS-232 Interface
o CAN Interface
o I2C, SPI with Debug through the Beagle connector from Total Phase

Chapter 3.Power Supply
3.1. Requirements
This RDK gets its power from the Segger J-Link Lite USB connection or optionally from a regulated 5V power supply.
The optional power jack is a center positive connector using a 2.1 mm barrel.
Warning
The RDK is neither under nor over-voltage protected. Use a 5v !REGULATED! center positive supply which can source at
least 1 Amp.
3.2. Power – Up Behavior
When the RDK is purchased it has the ‘Release’ or stand-alone code from Example #4 pre-programmed into the
Renesas microcontroller. The code exercises the user LEDs, LCD, PWM, ADC, Potentiometer, and Ethernet interfaces.
The LCD powers up with the message: “Micrium”, “uC/OS-III”, “uC/TCP-IP” message. If the Ethernet interface is active,
and a DHCP server is present, the RDK will receive an IP Address, subnet mask and Gateway address. All will be
displayed on the LCD. If no DHCP server is found, the RDK uses the default settings of:
IP Address = 169.254.24.194
Subnet Mask= 255.255.0.0
Gateway = 0.0.0.0
After acquiring the network address either by the DHCP server or by default, the speed of the motor control LEDs are
under the control of the potentiometer. Turning the potentiometer adjusts the desired frequency of the Motor Control
LEDs. The output frequency is also measured and both are displayed on the bottom of the LCD.
