HANDLING DEVICES
Preventing Latch-up
A latch-up can occur if, on this device, (a) a voltage higher than V
DD
or a voltage lower than V
SS
is applied to an
input or output pin or (b) a voltage higher than the rating is applied between V
DD
and V
SS
pins. The latch-up, if it
occurs, significantly increases the power supply current and may cause thermal destruction of an element. When
you use this device, be very careful not to exceed the maximum rating.
Handling unused pins
Do not leave an unused input pin open, since it may cause a malfunction. Handle by, using a pull-up or
pull-down resistor.
Unused output pin should be opened.
The attention when the external clock is used
Input the clock to XIN pin, and XOUT pin should be opened when you use the external clock.
Please pay attention so that an overshoot and an undershoot do not occur to an input clock of XIN pin.
Power supply pins
Please design connecting the power supply pin of this device by as low impedance as possible from the current
supply source.
We recommend connecting electrolytic capacitor (about 10
μ
F) and the ceramic capacitor (about 0.01
μ
F) in
parallel between V
SS
and V
DD
pins near the device, as a bypass capacitor.
Oscillation Circuit
Noise near the XIN and XOUT pins may cause the device to malfunction. Design printed circuit boards so that
electric wiring of XIN or XOUT pin and resonator (or ceramic oscillator) do not intersect other wiring.
Design the printed circuit board that surrounds the XIN and XOUT pins with ground.
