No part of this document may be copied or reproduced in any form or by any means without the prior written

consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in this

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, customers 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 is "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 an NEC sales representative in advance.

Anti-radioactive design is not implemented in this product.
