| .No | نماد | عملکرد | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | VSS | .Ground | |||||||||||||||
| 2 | VDD | .Power supply pin for core logic operation | |||||||||||||||
| 3 | V0 | .Keep float (i.e. disable). Power supply for panel driving voltage. This is also the most positive power voltage supply pin | |||||||||||||||
| 4 | D/C# | This is Data/Command control pin. When it is pulled HIGH (i.e. connect to VDDIO), the data at D[7:0] is treated as data. When it is pulled LOW, the data at D[7:0] will be transferred to .the command register .In I2C mode, this pin acts as SA0 for slave address selection |
|||||||||||||||
| 5 | R/W# | .This is read / write control input pin connecting to the MCU interface When interfacing to a 6800-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH (i.e. connect to VDDIO) 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 .When serial interface is selected, this pin must be connected to VSS |
|||||||||||||||
| 6 | E/RD# | (When interfacing to a 6800-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled HIGH (i.e. connect to VDDIO .and the chip is selected .When connecting to an 8080-microprocessor, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected .When serial interface is selected, this pin must be connected to VSS |
|||||||||||||||
| 7~14 | DB0~DB7 | .These are 8-bit bi-directional data bus to be connected to the microprocessor's 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 left opened. 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 |
|||||||||||||||
| 15 | CS# | (This pin is the chip select input. (active LOW | |||||||||||||||
| 16 | RES# | .This pin is reset signal input. When the pin is LOW, initialization of the chip is executed .Keep this pin HIGH (i.e. connect to VDDIO) during normal operation |
|||||||||||||||
| 17,18 | BS1, BS2 | Communicating Protocol Select. These pins are MCU interface selection input. See the following table:

| 21 | TP_SCK | I2C Clock | |||||||||||||||
| 22 | TP_SDA | I2C Data | |||||||||||||||
| 23 | TP_INT | Interrupt Output This pin is used as the dedicated interrupt output signal. |
|||||||||||||||
| 24 | TP_RST | Hardware Reset This pin is to reset hardware for this chip. |
