2 Symbol Definition
D0-D7：These pins are 8-bit bi-directional data bus to be connected to the MCU’s data bus. When
serial mode is selected , D1 will be the serial data input SDIN and D0 will be the serial input SCLK.
E/RD#：This pin 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
CS~ is pulled low. 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 CS# is pulled low.
W/R# :This pin in MCU interface input. When interfacing to a 6800 series microprocessor this pin
will be used as Read/Write(R/W#) selection input. Pull this pin to “High” for read mode and pull it
”Low” for write mode. When 8080 interface mode is selected this pin will be the Write(W/R#) input.
Data write operation is initiated when this pin is pulled low and the CS# is pulled low.
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 CS# is
pulled low.
BS1, BS2: This pins are MCU interface selection input, see the following table:
VCC: This is the most positive voltage supply pin of the chip. It can be supplied externally or
generated internally by using internal DC-DC voltage converter.
VDD: This is a voltage supply pin. It must be connected to external source.
VSS: This is a ground pin. It also a reference for the logic pins and the OLED driving voltages. It must
be connected to external ground.
VSL: This pin is the output pin for the voltage output low level for SEG signals. A capacitor should be
connected between this pin and Vss.
NC: These pins should be left open individually.
