Precaution
- When Mask ROM version, One-time PROM version and memory size differ in one group, actual values such
as an electrical characteristics, operation margin, A-D conversion accuracy, noise immunity, and noise
radiation may differ from the ideal values due to the difference in the manufacturing processes.
When these products are used switching, perform system evaluation for each product of every after confirming
product specification.
- This document shows difference, some specifications and standards, not for all.
Be sure to refer to the most current data sheet as for the latest detailed specification and an electrical characteristics.

2. Oscillation circuit constants
The oscillation circuit constants of XIN-XOUT, XCIN-XCOUT will depend on each
product of Mask ROM version (Standard version, M version, H version, A version)
and One-time PROM version.
So that the product used for mass production obtains the stabilized operation clock
on the user system and its condition, contact the resonator manufacturer and
select the resonator and oscillation circuit constants. Be careful especially when
range of voltage and temperature is wide.
We recommend to design the circuit in consideration of the wiring pattern of the
feed-back resistor, the dumping resistor and the load capacity in advance.
We publish the reference-use oscillation circuit parameters in Renesas Technology
home page.

To our customers,
Old Company Name in Catalogs and Other Documents
On April 1st, 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.

“High Quality”: Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anticrime systems; safety equipment; and medical equipment not specifically 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 devices or systems), surgical implantations, or healthcare
intervention (e.g. excision, etc.), and any other applications or purposes that pose a direct threat to human life.
You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics,
especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation
characteristics, installation and other product characteristics. Renesas Electronics shall have no liability for malfunctions or
damages arising out of the use of Renesas Electronics products beyond such specified ranges.
Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have
specific characteristics such as the occurrence of failure at a certain rate and malfunctions under certain use conditions. Further,
Renesas Electronics products are not subject to radiation resistance design. Please be sure to implement safety measures to
guard them against the possibility of physical injury, and injury or damage caused by fire in the event of the failure of a
Renesas Electronics product, such as safety design for hardware and software including but not limited to redundancy, fire
control and malfunction prevention, appropriate treatment for aging degradation or any 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.
Please contact a Renesas 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 regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS
Directive. Renesas Electronics assumes no liability for damages or losses occurring as a result of your noncompliance with
