Pin Definition
Pin No. Symbol I/O Function
1 Vss P
Ground of Logic Circuit
This is a ground pin. It also acts as a reference for the
logic pins. It must be connected to external ground.
2 VDD 3.3--5V
Power Supply for Display Module Circuit
This is a voltage supply pin. It connected to external
source.
3 V0 -
Power Supply for OEL Panel
This is the most positive voltage supply pin of the chip.
Please let it Float.
4 /DC I
Data/Command Control
This pin is Data/Command control pin. When the pin is
pulled high, the input at D7~D0 is treated as display data.
When the pin is pulled low, the input at D7~D0 will be
transferred to the command register. For detail relationship
to MCU interface signals, please refer to the Timing
Characteristics Diagrams.
5 /WR I
Read/Write Select or Write
This pin is MCU interface input, When interfacing to an
68XX-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 to “Low” for write mode. When
80XX 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 CS is pulled low.
6 /RD I
Read/Write Enable or Read
This pin is MCU interface input, When interfacing to an
68XX-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 CS is pulled low. When
connecting to an 80XX-microprocessor,this pin receives
the Read(RD) signal. Data read operation is initiated
when this pin is pulled low CS is pulled low.
7--14 DB0―DB7 I/O
Host Data Input/Output Bus
These pins are 8-bit bi-directional data bus to be
connected to the microprocessor’s data bus. When serial
mode is selected, D1 will be the serial data input SDIN
and D0 will be the serial clock input SCLK.
15 /CS I
Chip Select
