Old Company Name in Catalogs and Other Documents

On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology Corporation, and Renesas Electronics Corporation took over all the business of both companies. Therefore, although the old company name remains in this document, it is a valid Renesas Electronics document. We appreciate your understanding.

The quality grade of each Renesas Electronics product is “Standard” unless otherwise expressly specified in a Ren esas E lectronics data sheets or dat a books, etc.

“Standard”: Computers; office equipment; communications equipment; test and measurement equipment; audio and visual

equipment; home electron ic appliances; machine tools; personal electronic equipment; and industrial robots.

“High Quality”: Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-

crime systems; safety equipment; and medical equipment not specifically designed for life support.

“Specific”: Aircraft; aerospace equipment; submersible repeaters; nuclear reactor control systems; medical equipment or

systems for life support (e.g. artificial life support devices or systems), surgical implantations, or healthcare intervention (e.g. excision, etc.), and any other appl i cations or purposes that pose a d irect threat to human life.

8. You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics,

especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation characteristics, installation and other product characteristics. Renesas Electronics shall have no liability for malfunctions or damages arising out of the use of Renesas Electronics products beyond such specified ranges.

9. Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have

specific characteristics such as t he occu rrence o f failure at a certai n rate an d malfunct io ns under cert ain u se con dition s. Further, Renesas Electronics prod ucts are not subject to radiation resistance design. Please be sure to implement safety measures to guard them against the possibility of physical injury, and injury or damage caused by fire in the event of the failure of a Renesas Electronics product, such as safety design for hardware and software including but not limited to redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because the evaluation of microcomputer software alone is very difficult, please evaluate the safety of the final products or system manufactured by you.

10. Please contact a Renesas Electronics sales office for details as to environmental matters such as the environmental

compatibility of each Renesas Electronics product. Please use Renesas Electronics products in compliance with all applicable laws and regulations that regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS Directive. Renesas Electronics assumes no liability for damages or losses occurring as a result of your noncompliance with applicable laws and regulations.

11. This document may not be reproduced or duplicated, in any form, in whole or in part, without prior written consent of Renesas

Electronics.

12. Please contact a Renesas Electronics sales office if you have any questions regarding the information contained in this

document or Renesas Electronics products, or if you have any other inquiries.

Chapter 2. Purpose

This RSK is an evaluation tool for Renesas microcontrollers. Features include:

• Renesas Microcontroller Programming.

• User Code Debugging.

• User Circuitry such as switches, LEDs and potentiometer(s).

• Sample Application.

• Sample peripheral device initialisation code.

The CPU board contains all the circuitry required for microcontroller operation. 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.

Chapter 3. Power Supply

3.1. Requirements

This CPU board operates from a 5V power supply. A diode provides reverse polarity protection only if a current limiting power supply is used. All CPU boards are supplied with an E10A debug module and a PSU. When the CPU board is connected to another system that system

should supply power to the CPU board. All CPU boards have an optional centre positive supply connector using a 2.0mm barrel power jack.

Warning

The CPU board is neither under not over voltage protected. Use a centre positive supply for this board. Weher

possible use the supplied PSU.

3.2. Power – Up Behaviour

When the RSK is purchased the CPU 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. Pressing any switch will cause the LEDs to flash at a rate controlled by the potentiometer.
