2. PIN ASSIGNMENT OF THE DISPLAY
Pin Designation Pin number I/O Function
VSS 1 P Logic circuit ground
This is a ground pin. It also serves as a reference
for the logic pins. It must be connected to the
external ground.
VDD - 2 3,3 5V Power supply for display module circuit
This is a power supply pin.
V0 - 3 Voltage supply for OEL panel
This is the most positive voltage supply pin of
the chip.
Please do not connect it.
A0 4 I Data/Command Control
This pin is a data/command control pin. When
the pin is pulled high, the input at D7~D0 is trea-
ted as display data. When the pin is pulled low,
the input at D7~D0 is transferred to the com-
mand register.
/WR 5 I Read/Write Select or Write
This pin is an MCU interface input. When
connected to a 68XX series microprocessor, this
pin is used as a read/write select (R/W) input.
Pull this pin high for read mode and pull it low
for write mode. When the 80XX interface mode is
selected, this pin is the write input (WR). The da-
ta write operation is initiated when this pin is
pulled "Low" and CS is pulled "Low".
/RD 6 I Read/Write Enable or Read
This pin is an MCU interface input. When
connected to a 68XX series microprocessor, this
pin is used as an Enable(E) signal. The read/
write operation is initiated when this pin is pul-
led high and CS is pulled low. When connected
to an 80XX microprocessor, this pin receives the
Read(RD) signal. The data read operation is initi-
ated when this pin is pulled low and CS is pulled
low.

Pin Designation Pin number I/O Function
DB0 7 I/O
Host data input/output bus
These pins are bidirectional 8 bit data buses -
that connect to the microprocessor data
bus. When serial mode is selected, D1 is the
SDIN serial data input and D0 is the SCLK
serial clock input.
DB1 8 I/O
DB2 9 I/O
DB3 I/O 10
DB4 I/O 11
DB5 I/O 12
DB6 I/O 13
DB7 I/O 14
/CS I Chip Select 15 -
This pin is the chip select input. The chip is
only enabled for MCU communication when
CS# is pulled low.
/RESET I Power Reset for Controller and Driver 16
This pin is a reset signal input. When the pin
is low, the initialization of the chip is perfor-
med.
NC (BS1) H/L Communication protocol selection 17
These pins are inputs for selecting the MCU
interface.
