HANDLING DEVICES
1. Preventing Latch
-
up
Latchup may occur on CMOS ICs if voltage higher than V
CC
or lower than V
SS
is applied to input or output pins
other than medium- and high-voltage pins or if higher than the voltage which shows on “ 1. Absolute Maximum
Ratings” in “
I
Electrical Characteristics” is applied between V
CC
to V
SS
.
When latchup occurs, power supply current increases rapidly and might thermally damage elements. When
using, take great care not to exceed the absolute maximum ratings.
Also, take care to prevent the analog power supply (AV
CC
and AVR) and analog input from exceeding the digital
power supply (V
CC
) when the analog system power supply is turned on and off.
2. Treatment of Unused Input Pins
Leaving unused input pins open could cause malfunctions. They should be connected to pull-up or pull-down
resistor.
3. Treatment of Power Supply Pins on Microcontrollers with A/D and D/A Converters
Connect to be AV
CC
=DAVC=V
CC
and AV
SS
=AVR=V
SS
even if the A/D and D/A converters are not in use.
4. Treatment of N.C. Pin
Be sure to leave (internally connected) N.C. pins open.
5. Power Supply Voltage Fluctuations
Although operation is assured within the rated range of V
CC
power supply voltage, a rapid fluctuation of the
voltage could cause malfunctions within the rated range. Stabilizing voltage supplied to the IC is therefore
important. As stabilization guidelines, it is recommended to control power so that V
CC
ripple fluctuations (P-P
value) will be less than 10% of the standard V
CC
value at the commercial frequency (50 to 60 Hz) and the transient
fluctuation rate will be less than 0.1 V/ms at the time of a momentary fluctuation such as when power is switched.
6. Precautions when Using an External Clock
Even when an external clock is used, oscillation stabilization time is required for power-on reset (optional) and
release from stop mode.
