HANDLING DEVICES
1.
Preventing Latchup
CMOS ICs may cause latchup in the following situations:
When a voltage higher than Vcc or lower than Vss is applied to input or output pins.
When a voltage exceeding the rating is applied between Vcc and Vss.
When AVcc power is supplied prior to the Vcc voltage.
In turning on/turning off the analog power supply, make sure the analog power voltage (AV
CC
, AVRH, DV
CC
)and
analog input voltages not exceed the digital voltage (V
CC
).
2.
Treatment of unused pins
Leaving unused input pins open may result in misbehavior or latch up and possible permanent damage of the
device. Therefor they must be tied to V
CC
or Ground through resistors. In this case those resistors should be
more than 2 k<Symbol>W.
Unused bidirectional pins should be set to the output state and can be left open, or the input state with the above
described connection.
Notes on Using External Clock
3.
In using the external clock, drive X0 pin only and leave X1 pin unconnected.
4. Unused Sub Clock Mode
If sub clock modes are not used, the oscillator should be connected to the X01A pin and X1A pin
5.
Power Supply Pins (V
CC
/V
SS
)
In products with multiple V
CC
or V
SS
pins, the pins of a same potential are internally connected in the device to
avoid abnormal operations including latch-up. However, connect the pins external power and ground lines 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 current rating.
Make sure to connect V
CC
and V
SS
pins via lowest impedance to power lines.
