To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

have received the latest product standards or specifications before final design, purchase or
use.
3. Hitachi makes every attempt to ensure that its products are of high quality and reliability.
However, contact Hitachi’s sales office before using the product in an application that
demands especially high quality and reliability or where its failure or malfunction may directly
threaten human life or cause risk of bodily injury, such as aerospace, aeronautics, nuclear
power, combustion control, transportation, traffic, safety equipment or medical equipment for
life support.
4. Design your application so that the product is used within the ranges guaranteed by Hitachi
particularly for maximum rating, operating supply voltage range, heat radiation characteristics,
installation conditions and other characteristics. Hitachi bears no responsibility for failure or
damage when used beyond the guaranteed ranges. Even within the guaranteed ranges,
consider normally foreseeable failure rates or failure modes in semiconductor devices and
employ systemic measures such as fail-safes, so that the equipment incorporating Hitachi
