1. Overview
1.1 Purpose
This RSK+ is an evaluation tool for Renesas microcontrollers. This manual describes the technical details of the
RSK+ hardware. The Quick Start Guide and Tutorial Manual provide details of the software installation and
debugging environment.
1.2 Features
This RSK+ provides an evaluation of the following features:
•Renesas microcontroller programming
•User code debugging
•User circuitry such as switches, LEDs and a potentiometer
•Sample application
•Sample peripheral device initialisation code
The RSK+ board contains all the circuitry required for microcontroller operation.
1.3 Scope
This manual covers the RSK+RX63N-256K which is fitted a R5F563NFDDFC microcontroller.
For the RSK+RX63N please refer to User Manual R20UT2043EG, which can be found at
http://www.renesas.com/rskrx63n.

RSK+RX63N-256K 2. Power Supply
R20UT3076EG0100 Rev. 1.00 Page 9 of 54
Aug 14, 2014
2. Power Supply
2.1 Requirements
This RSK+ is supplied with an E1 debugger. The debugger is able to supply the RSK+ board with up to 200mA.
In applications requiring more than 200mA or when the E1 debugger is not used, the RSK+ must be powered
externally. All RSK and RSK+ boards have a centre positive supply connector using a 2.0mm barrel power jack.
This RSK+ supports a wide range of voltage inputs, and requires specific configuration for different inputs. Details
of the external power supply connections are shown in Table 2-1 below.

Table 2-1: Main Power Supply Requirements
This RSK+ features an independent USB power supply, which allows a user to power the USB host/OTG modules
from a second external power supply. Connections for the external USB power supply are detailed in Table 2-2
below.
Connector Supply Voltages
PWR2 (USB_3V3) Regulated, 3.3V DC
PWR3 (USB_5V) Regulated, 5V DC
Table 2-2: USB Power Supply Requirements
The RSK+ can also be powered directly from the USB VBUS, when a suitable host device is connected to the
USB0 connector and the RSK+ is correctly configured (refer to §6). This will limit the current consumption of the
RSK+ to 500mA (USB maximum), therefore full functionality cannot be achieved whilst being powered from the
USB VBUS.
This RSK+ also features a coin cell backup battery function which is used to power the real-time clock and sub-
clock oscillator when the voltage drop at the VCC pin is detected. Connections for the backup battery power supply
are detailed in Table 2-3 below.
Connector Supply Voltage
PWR4 2.3V to 3.6V DC
Table 2-3: Backup Battery Power Supply Requirements
2.2 Power-Up Behaviour
When the RSK+ is purchased, the RSK+ board has the ‘Release’ or stand-alone code from the example tutorial
code pre-programmed into the Renesas microcontroller. On powering up the board the user LEDs will start to flash.
After 200 flashes or after pressing any switch, the LEDs will flash at a rate controlled by the potentiometer.
The main power supply connected to PWR1 should supply a minimum of 5W to ensure full functionality.
The USB power supplies connected to PWR2 and PWR3 should both supply a minimum of 600mA to ensure full USB
host functionality. Note: The OTG module is limited to supply a maximum of 200mAwhen operating as host.

A reset control circuit is fitted to the RSK+ to generate the required reset signal, and is triggered from the RES
switch. Refer to the RX63N Group, RX631 Group User’s Manual: Hardware for details regarding the reset signal
timing requirements, and the RSK+RX63N board schematics for information regarding the reset circuitry in use on
the RSK+.
5.2 Clock Circuit
A clock circuit is fitted to the RSK+ to generate the required clock signal to drive the MCU, and associated
peripherals. Refer to the RX63N Group, RX631 Group User’s Manual: Hardware for details regarding the clock

* This connection is a not available in the default RSK+ configuration - refer to §6 for the required modifications.
5.5 Potentiometer
A single-turn potentiometer is connected as a potential divider to analog input AN000, pin 173. The potentiometer
can be used to create a voltage between AVCC0 and ground (by default, AVCC0 is connected to the MCU power
supply UC_VCC).
The potentiometer offers an easy method of supplying a variable analog input to the microcontroller. It does not
necessarily reflect the accuracy of the controller’s ADC. Refer to the device hardware manual for further details.
5.6 Debug LCD Module
A debug LCD module is supplied with the RSK+, and should be connected to the LCD header, LCD1.
Care should be taken when installing the LCD module to ensure pins are not bent or damaged. The LCD module is
vulnerable to electrostatic discharge (ESD); therefore appropriate ESD protection should be used.
The debug LCD module uses a 4-bit interface to reduce pin allocation. No contrast control is provided, as this is set
by a resistor supplied on the display module. Connection information for the debug LCD is provided in Table 5-4.

5.7 RS232 Serial Port
Serial port SCI0 is connected to the standard RS232 header fitted to the RSK+. Alternatively, serial port SCI1 or
SCI6 can be connected to the RS232 transceiver by making changes to the configurations to the jumpers and option
links (refer to §6). Connections between the RS232 header and the microcontroller are listed in the
Table 5-5.

5.9 Ethernet
When running any Ethernet software, a unique MAC address should be used. A unique Renesas allocated MAC
address is attached to the RSK+RX63N PCB as a sticker, and should always be used with this device to ensure full
compatibility when using other Renesas hardware on a common Ethernet connection.
An Ethernet controller IC is fitted to the RSK+, and is connected to the Ethernet MCU peripheral. The RX63N
MCU supports full duplex 10Mb/s and 100Mb/s transmission and reception. The Ethernet status LEDs (LED6 – 9)
are detailed in §5.4. The connections for the Ethernet controller are listed in Table 5-7 below.
