5

VDD-3.3V

3.3V power supply pad for Power supply for charge pump circuit.

This pin should be disconnected when VPP is supplied externally

6

VSS

This is a ground pin.

7

RES

This is a reset signal input pad. When /RES is set to “L”, the settings are

initialized. The reset operation is performed by the /RES signal level.

8

SCL

The serial clock input pad

9

SI

The serial data input pad

10

IREF

This is a segment current reference pad. A resistor should be connected between

this pad and VSS.

11

VCOMH

This is a pad for the voltage output high level for common signals.

A capacitor should be connected between this pad

12

VPP

OLED panel power supply. Generated by internal charge pump.

Connect to capacitor. It could be supplied externally
