Interface Pin Function

No.

Symbol

Function

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.

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.

This pin is the segment pre-charge voltage reference pin.
A capacitor should be connected between this pin and VSS.
No external power supply is allowed to connect to this pin.

VSL

This is a reserved pin. It should be connected to VLSS externally.

VLSS

Analog system ground pin. It must be connected to external ground.

VDD

VDD can be supplied externally (within the range of 1.65V to 2.6V) or regulated internally from VCI when VCI is >2.6V.A capacitor should be connected between VDD and VSS under all circumstances.

VCI

Low voltage power supply.
VCI must always be equal to or higher than VDD and VDDIO.

VDDIO

Power supply for interface logic level. It should match with the MCU interface voltage level and must be connected to external source.

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).In I2C mode, this pin must be connected to VSS.

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.

D/C#

This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data will be interpreted as data.
When the pin is pulled LOW, the data 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.

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: SID. 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.

BS0

MCU bus interface selection pins.

BS[1:0]	Interface
00	4-Wire SPI
01	3-Wire SPI
10	I2C

BS1

VSS

Ground pin.

IREF

When external IREF is used, a resistor should be connected between this pin and VSS to maintain current of around 18.75uA.
When internal IREF is used, this pin should be kept NC.

19~20

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.
