 HANDLING DEVICES
DS706-00007-1v0-E
 Power supply pins
 Crystal oscillator circuit
 Using an external clock
 Handling when using Multi function serial pin as I
In products with multiple VCC and VSS pins, respective pins at the same potential are interconnected
within the device in order to prevent malfunctions such as latch-up. However, all of these pins should be
connected externally to the power supply or ground lines in order to reduce electromagnetic emission levels,
to prevent abnormal operation of strobe signals caused by the rise in the ground level, and to conform to the
total output current rating.
Moreover, connect the current supply source with the VCC and VSS pins of this device at low impedance.
It is also advisable that a ceramic capacitor of approximately 0.1 µF be connected as a bypass capacitor
between VCC and VSS near this device.
Noise near the X0/X1 and X0A/X1A pins may cause the device to malfunction. Design the printed circuit
board so that X0/X1, X0A/X1A pins, the crystal oscillator (or ceramic oscillator), and the bypass capacitor
to ground are located as close to the device as possible.
It is strongly recommended that the PC board artwork be designed such that the X0/X1 and X0A/X1A pins
are surrounded by ground plane as this is expected to produce stable operation.
When using an external clock, the clock signal should be input to the X0,X0A pin only and the X1,X1A pin
should be kept open.
If it is using multi function serial pin as I
However, I
