■ HANDLING DEVICES
Power supply pins
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 pins near this device.
Crystal oscillator circuit
Noise near the X0 and X1 pins may cause the device to malfunction. Design the printed circuit board so that X0,
X1, 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 and X1 pins are surrounded
by ground plane as this is expected to produce stable operation.
If a 32 kHz oscillator is used (X0A, X1A), use the PK2 pin for an input that changes as infrequently as possible.
Furthermore, take steps such as shown in the following figure to prevent the X0A and PK2 wiring from running
parallel to each other.
If 32 kHz oscillation is not used, there are no limitations.
Using an external clock
When using an external clock, the clock signal should be input to the X0 pin only and the X1 should be kept open.
