the information in this document is current as of february 2002. the information is subject to change without notice. for actua l design-in, refer to the latest publications of nec's data sheets or data books, etc., for the most up-to-date specifications of nec semiconductor products. n ot all products and/or types are available in every country. please check with an nec sales representative for availability and additional information. no part of this document ma y be copied or reproduced in any form or by any means without prior written consent of nec. nec assumes no responsibility for any errors that may appear in this document. nec 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 semiconductor prod ucts 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 int ellectual property rights of nec or others. descriptions of circuits, software and other related information in this document are provided for illustrative purposes in semiconductor pr oduct operation and application examples. the incorporation of these circuits, software and information in the design of customer's equipment shall be done under the ful l responsibility of customer. nec assumes no responsibility for any losses incurred by customers or third parties arising from the use of these circuits, software and infor mation. while nec endeavours to enhance the quality, reliability and safety of nec semiconductor products, customers agree and acknowledge that the possibility of defects thereof c annot be eliminated entirely. to minimize risks of damage to property or injury (including death) to persons arising from defects in nec semiconductor products, customers must in corporate sufficient safety measures in their design, such as redundancy, fire-containment and anti-failure features. nec semiconductor products are classified into the foll owing three quality grades: standard , special and specific . the "specific" quality grade applies only to semiconductor products developed based on a customer-designated quality assurance program for a specific application. the recommended applications of a semiconductor product depend on its quality grade, as indicated below. customers must check the quality grade of each semiconductor product before using it in a particular application. "standard": computers, office equipment, communications equi pment, 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 s pecifically designed for life support). "specific": aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipme nt for life support, etc. the quality grade of nec semiconductor products is standard unless otherwise expressly specified in nec's data sheets or data books, etc. if customers wish to use nec semiconductor produ cts in applications not intended by nec, they must contact an nec sales representative in advance to determine nec's willingness to su pport a given application. (note) (1) "nec" as used in this statement means nec corporation and also includes its majority-owned subsidiaries. (2) "nec semiconductor products" means any semiconductor product developed or manufactured by or for nec (as defined above). to find out more about the products and services available from nec electronics inc., call 1-800-366-9782, fax 1-800-729-9288, or visit our web site at www.necel.com ? 2002/printed in u.s.a. document no. m16004eu1v0pb00 64 mb flash memory pd29f064115 block diagram block diagram
