Power Supply for Logic

__
CS

This pad is the chip select input. When /CS = “L”, then the chip select becomes active, and data/command I/O is enabled.

___
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.

This is the Data/Command control pad that determines whether the data bits are data or a command.
In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver.

SCL

The serial clock input pad

SI/SDA

The serial data input pad

Dummy Pin

IREF

This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75μA.

VCOMH

The pin is for COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.

VPP

OLED panel power supply.
