• The information in this document is current as of November, 2009. The information is subject to change without notice. For
actual design-in, refer to the latest publications of NEC Electronics data sheets or data books, etc., for the most up-to-date
specifications of NEC Electronics products. Not all products and/or types are available in every country. Please check with an
NEC Electronics sales representative for availability and additional information.
• No part of this document may be copied or reproduced in any form or by any means without the prior written consent of NEC
Electronics. NEC Electronics assumes no responsibility for any errors that may appear in this document.
• NEC Electronics does not assume any liability for infringement of patents, copyrights or other intellectual property rights of
third parties by or arising from the use of NEC Electronics products listed in this document or any other liability arising from the
use of such products. No license, express, implied or otherwise, is granted under any patents, copyrights or other intellectual
property rights of NEC Electronics or others.
• Descriptions of circuits, software and other related information in this document are provided for illustrative purposes in
semiconductor product operation and application examples. The incorporation of these circuits, software and information in
the design of a customer's equipment shall be done under the full responsibility of the customer. NEC Electronics assumes no
responsibility for any losses incurred by customers or third parties arising from the use of these circuits, software and
information.
• While NEC Electronics endeavors to enhance the quality, reliability and safety of NEC Electronics products, customers agree
and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize risks of damage to property
or injury (including death) to persons arising from defects in NEC Electronics products, customers must incorporate sufficient
safety measures in their design, such as redundancy, fire-containment and anti-failure features.
• NEC Electronics products are classified into the following three quality grades: "Standard", "Special" and "Specific". The
"Specific" quality grade applies only to NEC Electronics products developed based on a customer-designated "quality
assurance program" for a specific application. The recommended applications of an NEC Electronics product depend on its
quality grade, as indicated below. Customers must check the quality grade of each NEC Electronics product 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": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and
medical equipment for life support, etc.
The quality grade of NEC Electronics products is "Standard" unless otherwise expressly specified in NEC Electronics data
sheets or data books, etc. If customers wish to use NEC Electronics products in applications not intended by NEC Electronics,
they must contact an NEC Electronics sales representative in advance to determine NEC Electronics' willingness to support a
given application.
(Note 1) "NEC Electronics" as used in this statement means NEC Electronics Corporation and also includes its majority-owned
subsidiaries.
(Note 2) "NEC Electronics products" means any product developed or manufactured by or for NEC Electronics (as defined
above).
