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.

Cautions about operation!
Electrical properties presented on the data sheet for the mask ROM and ZTATTM versions will surely
and sufficiently satisfy the standard values. However, real capabilities, operation margin, noise margin,
and other properties may vary depending on differences of manufacturing processes, internal wiring
patterns, etc. Therefore, it is requested for users to carry out an evaluation test for each product on an
actual system under the same conditions to see its operation.
Memory register, data area, and stack area values are unstable immediately after power is turned on.
They must be initialized before use.
