2 Symbol Definition
D0-D7：These pins are 8-bit bi-directional data bus to be connected to the MCU’s data bus.
BS1, BS2：These input pins are used to configure MCU interface selection by appropriate logic
setting, which is described in the following table. User can fix these pins by jumper (J6, J7) or can
setup by programme.
E/RD#：This pin is MCU interface input. When interfacing to a 6800-series microprocessor, this pin
is 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.
R/W#：This pin is MCU interface input. When interfacing to a 6800-series microprocessor, this pin is
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 is 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
R/W must be connected to VSS.
D/C#：This pin is Data/Command control pin. When the pin is pulled high, the data at D0-D8 is
treated as display data. When the pin is pulled low, the data at D0-D8 is transferred to the command
register. For detail relationship to MCU interface signals, please refer to the timing characteristics
diagrams at following pages and datasheet.
RESET#：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.
VCC_IN: This is the external most positive voltage supply. This pin should be shorted with VCC by
Jumper 2 (J2)
VDD_IN: This is the external positive voltage supply. This pin should be shorted with VDD by
Jumper 3 (J3)
VDDIO: Power supply for interface logic level. It should be match with the MCU interface voltage
level. VDDIO must always be equal or lower than VDD (J8)
