CS#

This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled

low.

RES#

This pin is reset signal input. When the pin is low, initialization of the chip is executed.

relationship to MCU interface signals, please refer to the Timing Characteristics Diagrams.

R/W#(WR#)

This pin is MCU interface input. When interfacing to a 6800-series microprocessor, this pin will be used as

Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled high and write

mode when low.

When 8080 interface mode is selected, this pin will be the Write (WR#) input. Data write operation is

initiated when this pin is pulled low and the chip is selected.

When serial interface is selected, this pin E(RD#) must be connected to VSS.

E (RD#)

This pin is MCU interface input. When interfacing to a 6800-series microprocessor, this pin will be used as

the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the chip is

selected.

When connecting to an 8080-microprocessor, this pin receives the Read (RD#) signal. Data read

operation is initiated when this pin is pulled low and the chip is selected.

When serial interface is selected, this pin E(RD#) must be connected to VSS.

These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus.

Power Supply pin. This is also the reference for the OLED driving voltages. It must be connected to

external source.

Ground. It also acts as a reference for the logic pins. It must be connected to external ground.
