■ HANDLING DEVICES
1.
Preventing Latch-up
Latch-up may occur on CMOS IC if voltage higher than VCC or lower than VSS is applied to input and output pins
other than medium- to high-voltage pins or if higher than the voltage which shows on “1. Absolute Maximum
Ratings” in “
■ ELECTRICAL CHARACTERISTICS” is applied between VCC and VSS.
When latch-up occurs, power supply current increases rapidly and might thermally damage elements. When
using, take great care not to exceed the maximum ratings.
Also, take care to prevent the analog power supply (AVCC and AVR) and analog input from exceeding the digital
power supply (VCC) 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 a pull-up or pull-down
resistor.
3.
Treatment of Power Supply Pins on Microcontrollers with A/D
Connect to be AVCC
= VCC and AVSS = AVR = VSS even if the A/D is not in use.
4.
Treatment of N.C. Pins
Be sure to leave (internally connected) N.C. pins open.
5.
Power Supply Voltage Stabilization
Although VCC power supply voltage is assured to operate within the rated range, a rapid fluctuation of the voltage
could cause malfunctions, even if it occurs within the rated range. As stabilization guidelines, it is recommended
to control voltage fluctuation so that VCC ripple fluctuations (P-P value) will be less than 10
% of the standard VCC
value at the commercial frequency (50 Hz 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 and wake-up
from stop mode.
7.
Treatment of Unused dedicated LCD pins
When dedicated LCD pins are not in use, keep them open.
