PIN NAME

DESCRIPTION

NC 1 No Connection

VCC 2 OLED drive voltage 12~16V, It should be supplied externally S001 .

VCOMH 3

This is an input pin for the voltage output high level for COM signals. A

capacitor should be connected between this pin and VSS.

IREF 4

This is a segment current reference pin. A resistor should be

connected between this pin and VSS. Set thecurrent at 10uA.

D7-D0 5-12

These are 8-bit bi-directional data bus to be connected to the

microprocessor’s data bus. When serial interface mode is selected, D1

will be the serial data input, SDIN, and D0 will be the serial clock input,

SCLK.

E(RD#) 13

This is a MCU interface input pin. When 6800-series Parallel Interface

is selected, this pin is used as Enable (E) signal. Read/Write operation

is initiated when this pin is pulled HIGH and the CS# pin is pulled

LOW. When 8080-series Parallel Interface is selected, this pin is used

to receive the Read Data (RD#)signal. Data read operation is initiated

when this pin is pulled LOW and CS# pin is pulled LOW.
