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 a 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, firecontainment, 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: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, and 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.
