Commonly used with the MPU power supply pin V
0 V pin connected to the system ground (GND).
Boosting circuit reference power supply for liquid crystal drive.
External input pin for liquid crystal power supply voltage
adjusting circuit.
They are set to OPEN.
Multi-level power supply for liquid crystal drive. The voltage
by a split resistor or operation amplifier (OP amp) and applied.
The potential needs to be specified based on V
relationship of dimensions shown below:
Master operation When the power supply is ON, the following
voltages are applied to V
circuit. The selection of the voltages is determined using the LCD
bias set command.
a capacitor between the pin and CAP1– pin.
a capacitor between the pin and CAP1+ pin.
a capacitor between the pin and CAP2– pin.
a capacitor between the pin and CAP2+ pin.
a capacitor between the pin and CAP1+ pin.
Boosting output pin. Connects a capacitor between the pin and V
Voltage adjusting pin. Applies voltage between V
a split resistor.
Valid only when the V
(IRS=LOW)
Do not use VR when the V
used (IRS=HIGH)
specified according to liquid crystal cells is impedance-converted
