HANDLING DEVICES
1. Make Sure that the Voltage not Exceed the Maximum Rating (to Avoid a Latch-up).
In CMOS ICs, a latch-up phenomenon is caused when an voltage exceeding V
CC
or an voltage below V
SS
is
applied to input or output pins or a voltage exceeding the rating is applied across V
CC
and V
SS
.
When a latch-up is caused, the power supply current may be dramatically increased causing resultant thermal
break-down of devices. To avoid the latch-up, make sure that the voltage not exceed the maximum rating.
In turning on/turning off the analog power supply, make sure the analog power voltage (AV
CC
, AVRH) and analog
input voltages not exceed the digital voltage (V
CC
).
2. Connection of Unused Pins
Leaving unused pins open may result in abnormal operations. Clamp the pin level by connecting it to a pull-up
or a pull-down resistor.
3. Notes on Using External Clock
In using the external clock, drive X0 pin only and leave X1 pin unconnected.
4. Power Supply Pins
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 and 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.
It is recommended to provide a bypass capacitor of around 0.1
μ
F between V
CC
and V
SS
pin near the device.
5. Crystal Oscillator Circuit
Noises around X0 or X1 pins may be possible causes of abnormal operations. Make sure to provide bypass
capacitors via shortest distance from X0, X1 pins, crystal oscillator (or ceramic resonator) and ground lines, and
make sure, to the utmost effort, that lines of oscillation circuit not cross the lines of other circuits.
It is highly recommended to provide a printed circuit board art work surrounding X0 and X1 pins with an grand
area for stabilizing the operation.
