2 Symbol Definition
Note: The EVK is hard wired to 8080 Parallel interface.
D0-D7：These pins are 8-bit bi-directional data bus to be connected to the MCU’s data bus.
E/RD#：This pin is MCU interface input. 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.
R/W#：This pin is MCU interface input. 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.
D/C#：This pin is Data/Command control pin. When the pin is pulled high, the data at D7-
D0 is treated as display data. When the pin is pulled low, the data at D7-D0 will be transferred
to the command register. For detail relationship to MCU interface signals, please refer to the
timing characteristics diagrams.
RES#：This pin is reset signal input. When the pin is low, initialization of the chip is
executed.
CS#：This pin is the chip select input. The chip is enabled for MCU communication only
when CS is pulled low.
VCC：This is the most positive voltage supply pin of the chip.
VDD：Power Supply pin for logic operation of the driver.
VSS：This is a ground pin. It also acts as a reference for the logic pins and the OLED driving
voltages. It must be connected to external ground.
VCOMH：This is an input pin for the voltage output high level for COM signals. A
capacitor should be connected between this pin and VSS.
NC：Dummy pad. Do not group or short NC pins together.
