■ HANDLING DEVICES
• Preventing Latch-up
• Stable Supply Voltage
• Precautions for Use of External Clock
PIN CONNECTION
• Treatment of Unused Pin
• Treatment of Power Supply Pins on A/D Converter
• Power Supply Pins
Care must be taken to ensure that maximum voltage ratings are not exceeded when they are used.
Latch-up may occur on CMOS ICs if voltage higher than V
other than medium- and high-withstand voltage pins or if higher than the rating voltage is applied between V
pin and V
When latch-up occurs, power supply current increases rapidly and might thermally damage elements.
Also, take care to prevent the analog power supply voltage (AV
digital power supply voltage (V
Supply voltage should be stabilized.
A sudden change in power-supply voltage may cause a malfunction even within the guaranteed operating range
of the Vcc power-supply voltage.
For stabilization, in principle, keep the variation in Vcc ripple (p-p value) in a commercial frequency range
(50/60 Hz) not to exceed 10% of the standard Vcc value and suppress the voltage variation so that the transient
variation rate does not exceed 0.1 V/ms during a momentary change such as when the power supply is switched.
Even when an external clock is used, oscillation stabilization wait time is required for power-on reset, wake-up
from sub clock mode or stop mode.
Leaving unused input pins unconnected can cause abnormal operation or latch-up, leaving to permanent damage.
Unused input pins should always be pulled up or down through resistance of at least 2 kΩ. Any unused input/
output pins may be set to output mode and left open, or set to input mode and treated the same as unused input
pins. If there is unused output pin, make it open.

In products with multiple V
to avoid abnormal operations including latch-up. However, you must connect the pins to external power supply
and a ground line to lower the electro-magnetic emission level, to prevent abnormal operation of strobe signals
caused by the rise in the ground level, and to conform to the total output current rating.
Moreover, connect the current supply source with the V
It is also advisable to connect a ceramic bypass capacitor of approximately 0.1 µF between V
