to our customers, old company name in catalogs and other documents on april 1 st , 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. renesas electronics website: http://www.renesas.com april 1 st , 2010 renesas electronics corporation issued by: renesas electronics corporation (http://www.renesas.com) send any inquiries to http://www.renesas.com/inquiry.
notice 1. all information included in this document is current as of the date this document is issued. such information, however, is subject to change without any prior notice. before purchasing or using any renesas el ectronics products li sted herein, please confirm the latest product information with a renesas electronics sales office. also , please pay regular and careful attention to additional and different information to be disclosed by rene sas electronics such as that disclosed through our website. 2. renesas electronics does not assume any liability for infringeme nt of patents, copyrights, or other intellectual property ri ghts of third parties by or arising from the use of renesas electroni cs products or techni cal information descri bed in this document . no license, express, implied or otherwise, is granted hereby under any patents, copyri ghts or other intell ectual property right s of renesas electronics or others. 3. you should not alter, modify, copy, or otherwise misappropriate any re nesas electronics product, wh ether in whole or in part . 4. descriptions of circuits, software and other related informat ion in this document are provided only to illustrate the operat ion of semiconductor products and application examples. you are fully re sponsible for the incorporation of these circuits, software, and information in the design of your equipment. renesas electronics assumes no responsibility for any losses incurred by you or third parties arising from the use of these circuits, software, or information. 5. when exporting the products or technology described in this doc ument, you should comply with the applicable export control laws and regulations and follow the proc edures required by such laws and re gulations. you should not use renesas electronics products or the technology described in this docum ent for any purpose relating to mil itary applicati ons or use by the military, including but not l imited to the development of weapons of mass de struction. renesas electronics products and technology may not be used for or incor porated into any products or systems whose manufacture, us e, or sale is prohibited under any applicable dom estic or foreign laws or regulations. 6. renesas electronics has used reasonable care in preparing th e information included in this document, but renesas electronics does not warrant that such information is error free. renesas electronics assumes no liability whatsoever for any damages incurred by you resulting from errors in or omissions from the information included herein. 7. renesas electronics products ar e classified according to the following three quality grades: ?standard?, ?high quality?, an d ?specific?. the recommended applications for each renesas electronics product de pends on the product?s quality grade, as indicated below. you must check the qua lity grade of each renesas electronics pr oduct before using it in a particular application. you may not use any renesas electronics produc t for any application categorized as ?speci fic? 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. re nesas electronics shall not be in any way liable for any damages or losses incurred by you or third partie s arising from the use of any renesas electronics product for a n application categorized as ?specific? or for which the product is not intende d where you have failed to obtain the prior writte n consent of renesas electronics. the quality grade of each renesas electronics product is ?standard? unless otherwise expressly specified in a renesas electr onics data sheets or data books, etc. ?standard?: computers; office equipmen t; communications e quipment; test and measurement equipment; audio and visual equipment; home electronic a ppliances; machine tools; personal electronic equipmen t; and industrial robots. ?high quality?: transportation equi pment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; an ti- crime systems; safety equipment; and medical equipment not specif ically 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 device s or systems), surgical im plantations, or healthcare intervention (e.g. excision, etc.), and any other applicati ons or purposes that pose a di rect threat to human life. 8. you should use the renesas electronics pr oducts described in this document within the range specified by renesas electronics , especially with respect to the maximum ra ting, operating supply voltage range, movement power volta ge range, heat radiation characteristics, installation and other product characteristics. renesas electronics shall have no liability for malfunctions o r 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 produc ts, semiconductor products have specific characteristics such as the occurrence of failure at a certain rate a nd malfunctions under certain use conditions. fur ther, renesas electronics products are not subject to radiation resistance design. please be sure to implement safety measures to guard them against the possibility of physic al injury, and injury or damage caused by fire in the event of the failure of a renesas electronics product, such as safe ty design for hardware and software in cluding but not limited to redundancy, fire control and malfunction prevention, appropri ate treatment for aging degradation or an y 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 renesa s 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 regul ate the inclusion or use of c ontrolled substances, including wi thout limitation, the eu rohs directive. renesas electronics assumes no liability for damage s or losses occurring as a result of your noncompliance with applicable laws and regulations. 11. this document may not be reproduced or duplicated, in any form, in w hole or in part, without prio r written consent of renes as electronics. 12. please contact a renesa s electronics sales office if you have any questi ons regarding the informat ion contained in this document or renesas electroni cs products, or if you have any other inquiries.

"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. (2) "nec electronics products" means any product developed or manufactured by or for nec electronics (as defined above). ? ? ? ? ? ? m8e 02. 11-1
