Interface Pin Function

Pin No. Symbol Description
1 VSS Ground pin.
2 VCC Power supply for panel driving voltage. This is also the most positive power voltage supply pin.
3 VCOMH COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.
4 VCI Power supply pin for core logic operation
5 NC No connection
6 BS1 MCU bus interface selection pins.
Select appropriate logic setting as described in the following table.

BS1
I2C 1
4-wire Serial 0

Note
(1) 0 is connected to VSS
(2) 1 is connected to VCI
7 IREF This is segment output current reference pin.
When external IREF is used, a resistor should be connected between this pin and VSS to maintain the IREF current at a maximum of 30uA.
8 CS# This pin is the chip select input. (active LOW).
9 RES# This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is executed.
Keep this pin HIGH during normal operation.
10 D/C# When 4-wire serial interface is selected, this pin is Data/Command control pin connecting to the MCU.
In I2C mode, this pin acts as SA0 for slave address selection.
11 D0 These pins are bi-directional data bus connecting to the MCU data bus.
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.
12 D1
13 D2
14 NC No connection
15 NC No connection
16 NC No connection
17 VCC Power supply for panel driving voltage. This is also the most positive power voltage supply pin.
18 VSS Ground pin.
