Power supply pin for logic circuit to +2.2 to 3.3V
Ground pin for logic circuit, connect to 0V
Ground pin for high voltage circuit, connected to 0V
Bias power supply pin for LCD drive voltage
When the internal power supply circuit is active, these voltages are generated by the
built-in booster and voltage converter. Then, must connect capacitor each to VSS.
Connecting pin for the built in booster’s capacitor + side.
The capacitor is connected between CAP1- and CAP1+.
Connecting pin for the built in booster’s capacitor – side.
The capacitor is connected between CAP1- and CAP1+.
Connecting pin for the built in booster’s capacitor + side.
The capacitor is connected between CAP2- and CAP2+.
Connecting pin for the built in booster’s capacitor – side.
The capacitor is connected between CAP2- and CAP2+.
Connecting pin for the built in booster’s capacitor + side.
The capacitor is connected between CAP3- and CAP3+.
Connecting pin for the built in booster’s capacitor - side.
The capacitor is connected between CAP3- and CAP3+.
Connecting pin for the built in booster’s capacitor + side.
The capacitor is connected between CAP2- and CAP4+.
Voltage supply pin for booster circuit. Usually the same voltage level as VDD.
In the case of TCP, draw it as a separate terminal.
Output pin of boosted voltage in the built-in booster.
The capacitor must be connected between this pin and VSS.
Output pin which is equal to 2 x VEE.
The capacitor must be connected between this pin and VSS.
