.No الرمز الوظيفة
1 VSS Ground pin. It must be connected to external ground
2 VCC Power supply for panel driving voltage. This is also the most positive power voltage supply pin. It is supplied by external high voltage source
3 VCOMH COM signal deselected voltage level
A capacitor should be connected between this pin and VSS. No external power supply is allowed to connect to this pin
4 VCI Low voltage power supply and power supply for interface logic level. It should match with the MCU interface voltage level and must be connected to external source
VCI must always set to be equivalent to or higher than VDD
5 VDD Power supply pin for core logic operation
6 BS1 MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2, BS1 and BS0 are pin select
Bus Interface selection
[BS[2:1 Interface
0 4 line SPI
1 I2C
11 8-bit 8080 parallel
10 8-bit 6800 parallel

Note  (1) 0 is connected to VSS  (2) 1 is connected to VCI
7 BS2
8 VSS Ground pin. It must be connected to external ground
9 IREF This pin is the segment output current reference pin
10 CS# This pin is the chip select input connecting to the MCU
(The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW
11 RES# This pin is reset signal input
When the pin is pulled LOW, initialization of the chip is executed
Keep this pin pull HIGH during normal operation
12 D/C This pin is Data/Command control pin connecting to the MCU
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register
In I2C mode, this pin acts as SA0 for slave address selection
When 3-wire serial interface is selected, this pin must be connected to VSS
13 W/R# This pin is read / write control input pin connecting to the MCU interface
When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW
When 8080 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 chip is selected
14 RD# This pin is MCU interface input
When 6800 interface mode is selected, this pin will be used as the Enable (E) signal
Read/write operation is initiated when this pin is pulled HIGH and the chip is
selected.
When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected
When serial or I2C interface is selected, this pin must be connected to VSS
15 D0 These pins are bi-directional data bus connecting to the MCU data bus
Unused pins are recommended to tie LOW
When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN and D2 should be kept NC
When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL
