PIN DESCRIPTIONS
The basic functions of each pin of the ML63187/ML63189B are described in Table 1.
A symbol with a slash (/) denotes a pin that has a secondary function.
Refer to Table 2 for secondary functions.
For type, "—" denotes a power supply pin, "I" an input pin, "O" an output pin, and "I/O" an input-
output pin.

Description
Positive power supply
Negative power supply
Power supply pins for LCD bias (internally generated).
Capacitors (0.1 mF) should be connected between these
pins and VSS.
Capacitor connection pins for LCD bias generation.
A capacitor (0.1 mF) should be connected between C1 and C2.
Positive power supply pin for external interface
(power supply for input, and input-output ports)
Positive power supply pin for internal logic (internally
generated).
A capacitor (0.1 mF) should be connected between this
pin and VSS.
Voltage multiplier pin for power supply backup
(internally generated).
A capacitor (1.0 mF) should be connected between this
pin and VSS.
Pins to connect a capacitor for voltage multiplier.
A capacitor (1.0 mF) should be connected between CB1
and CB2.
Low-speed clock oscillation pins.
An option for using crystal oscillation or RC oscillation
is chosen by the mask option.
If the crystal oscillation is chosen, a crystal should be
connected between XT0 and XT1, and capacitor (CG)
should be connected between XT0 and VSS.
If the RC oscillation is chosen, external oscillation
resistor (ROSL) should be connected between XT0 and
XT1.
High-speed clock oscillation pins.
A ceramic resonator and capacitors (CL0, CL1) or external
oscillation resistor (ROSH) should be connected to these pins.
