5. Renesas Electronics products are classified according to the following two quality grades: “Standard” and “High Quality”. The
recommended applications for each Renesas Electronics product depends on the product’s quality grade, as indicated below.
“Standard”:
Computers; office equipment; communications equipment; test and measurement equipment; audio and visual
equipment; home electronic appliances; machine tools; personal electronic equipment; and industrial robots etc.
“High Quality”: Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anti-crime
systems; and safety equipment etc.
Renesas Electronics products are neither intended nor authorized for use in products or systems that may pose a direct threat to human
life or bodily injury (artificial life support devices or systems, surgical implantations etc.), or may cause serious property damages
(nuclear reactor control systems, military equipment etc.). You must check the quality grade of each Renesas Electronics product
before using it in a particular application. You may not use any Renesas Electronics product for any application for which it is not
intended. Renesas Electronics shall not be in any way liable for any damages or losses incurred by you or third parties arising from the
use of any Renesas Electronics product for which the product is not intended by Renesas Electronics.
6. 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.
7. 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 systems manufactured by you.
8. 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 applicable laws and regulations.
9. Renesas Electronics products and technology may not be used for or incorporated into any products or systems whose manufacture, use,
or sale is prohibited under any applicable domestic or foreign laws or regulations. You should not use Renesas Electronics products or
technology described in this document for any purpose relating to military applications or use by the military, including but not limited to
the development of weapons of mass destruction. When exporting the Renesas Electronics products or technology described in this
document, you should comply with the applicable export control laws and regulations and follow the procedures required by such laws
and regulations.
10. It is the responsibility of the buyer or distributor of Renesas Electronics products, who distributes, disposes of, or otherwise places the
product with a third party, to notify such third party in advance of the contents and conditions set forth in this document, Renesas
Electronics assumes no responsibility for any losses incurred by you or third parties as a result of unauthorized use of Renesas
Electronics products.
11. This document may not be reproduced or duplicated in any form, in whole or in part, without prior written consent of Renesas
Electronics.
12. Please contact a Renesas Electronics sales office if you have any questions regarding the information contained in this document or
Renesas Electronics products, or if you have any other inquiries.
(Note 1) “Renesas Electronics” as used in this document means Renesas Electronics Corporation and also includes its majority-owned
subsidiaries.
(Note 2) “Renesas Electronics product(s)” means any product developed or manufactured by or for Renesas Electronics.

General Precautions in the Handling of Microprocessing Unit and
Microcontroller Unit Products
The following usage notes are applicable to all Microprocessing unit and Microcontroller unit products from
Renesas.
For detailed usage notes on the products covered by this document, refer to the relevant sections of the
document as well as any technical updates that have been issued for the products.
1. Handling of Unused Pins
Handle unused pins in accordance with the directions given under Handling of Unused Pins in the
manual.
• The input pins of CMOS products are generally in the high-impedance state. In operation with an
unused pin in the open-circuit state, extra electromagnetic noise is induced in the vicinity of LSI, an
associated shoot-through current flows internally, and malfunctions occur due to the false recognition
of the pin state as an input signal become possible. Unused pins should be handled as described under
Handling of Unused Pins in the manual.
2. Processing at Power-on
The state of the product is undefined at the moment when power is supplied.
• The states of internal circuits in the LSI are indeterminate and the states of register settings and pins
are undefined at the moment when power is supplied.
In a finished product where the reset signal is applied to the external reset pin, the states of pins are
not guaranteed from the moment when power is supplied until the reset process is completed.
In a similar way, the states of pins in a product that is reset by an on-chip power-on reset function are
not guaranteed from the moment when power is supplied until the power reaches the level at which
resetting has been specified.
3. Prohibition of Access to Reserved Addresses
Access to reserved addresses is prohibited.
• The reserved addresses are provided for the possible future expansion of functions. Do not access
these addresses; the correct operation of LSI is not guaranteed if they are accessed.
4. Clock Signals
After applying a reset, only release the reset line after the operating clock signal has become stable.
When switching the clock signal during program execution, wait until the target clock signal has
stabilized.
• When the clock signal is generated with an external resonator (or from an external oscillator) during a
reset, ensure that the reset line is only released after full stabilization of the clock signal.
Moreover, when switching to a clock signal produced with an external resonator (or by an external
oscillator) while program execution is in progress, wait until the target clock signal is stable.
5. Differences between Products
Before changing from one product to another, i.e. to a product with a different part number, confirm that
the change will not lead to problems.
• The characteristics of Microprocessing unit or Microcontroller unit products in the same group but
having a different part number may differ in terms of the internal memory capacity, layout pattern,
and other factors, which can affect the ranges of electrical characteristics, such as characteristic
values, operating margins, immunity to noise, and amount of radiated noise. When changing to a
product with a different part number, implement a system-evaluation test for the given product.
