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.

RSK+RX62N 2. Power Supply

2. Power Supply

2.1 Requirements

This RSK+ is supplied with an E1 debugger. The debugger is able to power the RSK+ board with up to 200mA.
When the RSK is connected to another system then that system should supply power to the RSK+. All RSK and
RSK+ boards have an optional 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.

Connector Supply Voltages J10 Setting J11 Setting

Regulated, 5V DC Shorted Shorted PWR1

The main power supply connected to PWR1 should supply a minimum of 5W to ensure full functionality.

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 Ta bl e 2- 2
below.

Connector Supply Voltages

PWR2 Regulated, 3.3V DC
PWR3 Regulated, 5V DC

Unregulated, 7 to 15V DC Open Open

Table 2-1: Main Power Supply Requirements

Table 2-2: USB Power Supply Requirements

The USB power supplies connected to PWR2 and PWR3 should both supp ly a minimum of 600mA to ensure full USB
host functionality. Note: The OTG module is limited to supply a maximum of 200mA when operating as host.

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 can not be achieved whilst being powered from the
USB VBUS.

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.
