|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | ESD_GND | P | Ground | ||||||||||
| 2 | VSS | P | Ground. | ||||||||||
| 3 | VCC | P | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. |
||||||||||
| 4 | VCOMH | P | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
||||||||||
| 5 | VLSS | P | Analog system ground pin. | ||||||||||
| 6~13 | D7~D0 | I/O | Host Data Input/Output Bus These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. |
||||||||||
| 14 | E/RD# | I | Read/Write Enable or Read This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the CS# is pulled low. When connecting to an 80XX-microprocessor, this pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low. When serial mode is selected, this pin must be connected to VSS. |
||||||||||
| 15 | R/W# | I | Read/Write Select or Write This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and pull it to “Low” for write mode. When 80XX 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 CS# is pulled low. When serial mode is selected, this pin must be connected to VSS. |
||||||||||
| 16 | BS0 | I | Communicating Protocol Select These pins are MCU interface selection input. See the following table:
Note (1) 0 is connected to VSS (2) 1 is connected to VDDIO |
||||||||||
| 17 | BS1 | ||||||||||||
| 18 | D/C# | I | Data/Command Control This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the content at D[7:0] will be interpreted as data. When the pin is pulled LOW, the content at D[7:0] will be interpreted as command. |
