產品規格

Pin功能定義

No. 符號 功能說明
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.
VDD can be supplied externally (within the range of 2.4V to 2.6V) or regulated
Internally from VCI. A capacitor should be connected between VDD and VSS under all circumstances.
6 BS1

MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2 and BS1 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.
