To all our customers
Regarding the change of names mentioned in the document, such as Mitsubishi
Electric and Mitsubishi XX, to Renesas Technology Corp.
The semiconductor operations of Hitachi and Mitsubishi Electric 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 Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi
Semiconductors, and other Mitsubishi 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.
Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices
and power devices.

Keep safety first in your circuit designs!
q
Mitsubishi Electric Corporation puts the maximum effort into making semiconductor
products better and more reliable, but there is always the possibility that trouble may
occur with them. Trouble with semiconductors may lead to personal injury, fire or
property damage. Remember to give due consideration to safety when making your
circuit designs, with appropriate measures such as (i) placement of substitutive,
auxiliary circuits, (ii) use of non-flammable material or (iii) prevention against any
malfunction or mishap.
