2. Interface Pin Function
No. Symbol Function
1
N.C.
(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 C2N
Positive Terminal of the Flying Inverting Capacitorr Negative Terminal of
the Flying Boost Capacitor The charge-pump capacitors are required
between the terminals. They must be floated when the converter is not
used.
3 C2P
4 C1P
5 C1N
6 VBAT
Power Supply for DC/DC Converter Circuit
This is the power supply pin for the internal buffer of the DC/DC voltage
converter. It must be connected to
external source when the converter is
used. It should be connected to VDD when the converter is not used.
7 NC NC
8 VSS
Ground of Logic Circuit
This is a ground pin. It acts as a reference for the logic pins. It must be
connected to external ground.
9 VDD
Power Supply for Logic
This is a voltage supply pin. It must be connected to external source.
10 BS0
Communicating Protocol Select
These pins are MCU interface selection input. See the
following table:
11 BS1
12 BS2
13 CS#
Chip Select
This pin is the chip select input. The chip is enabled for MCU
communication only when CS# is pulled low.
14 RES#
Power Reset for Controller and Driver
This pin is reset signal input. When the pin is low,
initialization of the chip
is executed.
15 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.
