INTERFACE PIN FUNCTION
PIN NO. SYMBOL FUNCTION
1 NC (GND)
Reserved pin (supporting pin)
The supporting pins can reduce the influences from stresses on the function pins. These pins must be
connected to external ground.
2V
LSS
Ground of analog circuit
This is an analog ground pin. It should be connected to V
SS
externally.
3V
SS
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.
4NC
Reserved pin
The NC pins between function pins are reserved for compatible and flexible design.
5V
DD
Power supply for logic circuit. This is a voltage supply pin. It must be connected to external source.
6BS1
Communicating protocol select
These pins are MCU interface selection input. See the following table:
68XX-parallel 80XX-parallel Serial I
2
C
7BS2
BS1 0101
BS2 1100
8CS#
Chip select
This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low.
9RES#
Power reset for controller and driver
This pin is reset signal input. When the pin is low, initialization of the chip is executed.
10 D / C#
Data / command control
This pin is data / command control pin. When the pin is pulled high, the input at D7 to D0 is treated as
display data. When the pin is pulled low, the input at D7 to D0 will be transferred to the command register.
For detail relationship to MCU interface signals, please refer to the timing characteristics diagrams. When
the pin is pulled high and serial interface mode is selected, the data at SDIN is treated as data. When it is
pulled low, the data at SDIN will be transferred to the command register. In I
2
C mode, this pin acts as SA0
for slave address selection.
11 R / W#
Read / write select or write
This pin is MCU interface input. When interfacing to a 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.
12 E / RD#
Read / write enable or read
This pin is MCU interface input. When interfacing to a 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 and CS# is pulled low.
13 to 20 D0 to D7
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.
When I
2
C mode is selected, D2 and D1 should be tired together and serve as SDA
out
and SDA
in
in
application and D0 is the serial clock input SCL.
21 I
REF
Current reference for brightness adjustment
This pin is segment current reference pin. A resistor should be connected between this pin and V
SS
. Set
the current lower than 10 μA.
22 V
COMH
Voltage output high level for COM signal
This pin is the input pin for the voltage output high level for COM signals. A capacitor should be connected
between this pin and V
SS
.
23 V
CC
Power supply for OEL panel
This is the most positive voltage supply pin of the chip. It must be supplied externally.
24 GND
Reserved pin (supporting pin)
The supporting pins can reduce the influences from stresses on the function pins. These pins must be
connected to external ground.
