2. 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.
2
VLSS
Ground of Analog Circuit
This is an analog ground pin. It should be connected to VSS
externally.
3
VSS
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.
4
NC
Reserved Pin
The N.C. pins between function pins are reserved for
compatible and flexible design.
5
VDD
Power Supply for Logic Circuit
This is a voltage supply pin. It must be connected to external
source.
6
BS1
Communicating Protocol Select
These pins are MCU interface selection input. See the
following table:
68XX-parallel 80XX-parallel Serial I2C
BS1 0 1 0 1
BS2 1 1 0 0
7
BS2
8
CS#
Chip Select
This pin is the chip select input. The chip is enabled for
MCU communication only when CS# is pulled low
9
RES#
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~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.
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 I2C mode, this pin acts as SA0 for
slave address selection.
