8. When using Renesas Electronics products, refer to the latest product information (data sheets, user’s manuals, application notes, “General Notes for

Handling and Using Semiconductor Devices” in the reliability handbook, etc.), and ensure that usage conditions are within the ranges specified by

Renesas Electronics with respect to maximum ratings, operating power supply voltage range, heat dissipation characteristics, installation, etc. Renesas

Electronics disclaims any and all liability for any malfunctions, failure or accident arising out of the use of Renesas Electronics products outside of such

specified ranges.

9. Although Renesas Electronics endeavors to improve the quality and reliability of Renesas Electronics products, semiconductor products have specific

characteristics, such as the occurrence of failure at a certain rate and malfunctions under certain use conditions. Unless designated as a high reliability

product or a product for harsh environments in a Renesas Electronics data sheet or other Renesas Electronics document, Renesas Electronics products

are not subject to radiation resistance design. You are responsible for implementing safety measures to guard against the possibility of bodily injury,

injury or damage caused by fire, and/or danger to the public in the event of a failure or malfunction of Renesas Electronics products, 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 and impractical, you are

responsible for evaluating the safety of the final products or systems manufactured by you.

10. Please contact a Renesas Electronics sales office for details as to environmental matters such as the environmental compatibility of each Renesas

Electronics product. You are responsible for carefully and sufficiently investigating applicable laws and regulations that regulate the inclusion or use of

controlled substances, including without limitation, the EU RoHS Directive, and using Renesas Electronics products in compliance with all these

applicable laws and regulations. Renesas Electronics disclaims any and all liability for damages or losses occurring as a result of your noncompliance

with applicable laws and regulations.

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. Precaution against Electrostatic Discharge (ESD)

A strong electrical field, when exposed to a CMOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps

must be taken to stop the generation of static electricity as much as possible, and quickly dissipate it when it occurs. Environmental control must be

adequate. When it is dry, a humidifier should be used. This is recommended to avoid using insulators that can easily build up static electricity.

Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement

tools including work benches and floors must be grounded. The operator must also be grounded using a wrist strap. Semiconductor devices must not be

touched with bare hands. Similar precautions must be taken for printed circuit boards with mounted semiconductor devices.

2. Processing at power-on

The state of the product is undefined at the time 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 time 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 time 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 time when power is supplied until the power reaches the

level at which resetting is specified.

3. Input of signal during power-off state

Do not input signals or an I/O pull-up power supply while the device is powered off. The current injection that results from input of such a signal or I/O

pull-up power supply may cause malfunction and the abnormal current that passes in the device at this time may cause degradation of internal elements.

Follow the guideline for input signal during power-off state as described in your product documentation.

4. 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

the 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.

5. Clock signals

After applying a reset, only release the reset line after the operating clock signal becomes stable. When switching the clock signal during program

execution, wait until the target clock signal is 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. Additionally, 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.

6. Voltage application waveform at input pin

Waveform distortion due to input noise or a reflected wave may cause malfunction. If the input of the CMOS device stays in the area between V

IL

(Max.)

and V

IH

(Min.) due to noise, for example, the device may malfunction. Take care to prevent chattering noise from entering the device when the input level

is fixed, and also in the transition period when the input level passes through the area between V

IL

(Max.) and V

IH

(Min.).

7. Prohibition of access to reserved addresses

Access to reserved addresses is prohibited. The reserved addresses are provided for possible future expansion of functions. Do not access these

addresses as the correct operation of the LSI is not guaranteed.

8. Differences between products

Before changing from one product to another, for example to a product with a different part number, confirm that the change will not lead to problems.

The characteristics of a microprocessing unit or microcontroller unit products in the same group but having a different part number might differ in terms

of 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.
