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 oporate trademark, logo and
corporate statement, no changes whatsoever have been made to of the document, and
these changes do not constitute any alteration to the contenelf.

2. Waveform - A is for an output with internal conditions such that the output is low except
when disabled by the output control.
3. Waveform - B is for an output with internal conditions such that the output is high except
when disabled by the output control.
4. The output are measured one at a time with one transition per measurement.
