To our customers,

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.

7. Renesas Electronics products are classified according to the following three quality grades: “Standard”, “High Quality”, and

“Specific”. The recommended applications for each Renesas Electronics product depends on the product’s quality grade, as

indicated below. You must check the quality grade of each Renesas Electronics product before using it in a particular

application. You may not use any Renesas Electronics product for any application categorized as “Specific” without the prior

written consent of Renesas Electronics. Further, you may not use any Renesas Electronics product for any application for

which it is not intended without the prior written consent of Renesas Electronics. Renesas Electronics shall not be in any way

liable for any damages or losses incurred by you or third parties arising from the use of any Renesas Electronics product for an

application categorized as “Specific” or for which the product is not intended where you have failed to obtain the prior written

consent of Renesas Electronics. The quality grade of each Renesas Electronics product is “Standard” unless otherwise

expressly specified in a Renesas Electronics data sheets or data books, etc.

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

equipment; home electronic 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 applications or purposes that pose a direct 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 the occurrence of failure at a certain rate and malfunctions under certain use conditions. Further,

Renesas Electronics products 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.

document.

NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual

property rights of third parties by or arising from use of a device described herein or any other liability arising

from use of such device. No license, either express, implied or otherwise, is granted under any patents,

copyrights or other intellectual property rights of NEC Corporation or others.

While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,

the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or

property arising from a defect in an NEC semiconductor device, customer must incorporate sufficient safety

measures in its design, such as redundancy, fire-containment, and anti-failure features.

NEC devices are classified into the following three quality grades:

“Standard“, “Special“, and “Specific“. The Specific quality grade applies only to devices developed based on

a customer designated “quality assurance program“ for a specific application. The recommended applications

of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each

device before using it in a particular application.

Standard: Computers, office equipment, communications equipment, test and measurement equipment,

audio and visual equipment, home electronic appliances, machine tools, personal electronic

equipment and industrial robots

Special: 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: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life

support systems or medical equipment for life support, etc.

The quality grade of NEC devices in “Standard“ unless otherwise specified in NEC's Data Sheets or Data Books.

If customers intend to use NEC devices for applications other than those specified for Standard quality grade,

they should contact NEC Sales Representative in advance.

Anti-radioactive design is not implemented in this product.
