| NO | 기호 | 기능 | I/O |
|---|---|---|---|
| 1 | GND | Ground | P |
| 2-6 | NC | No connection | - |
| 7 | VCI | High voltage power supply for analog circuit blocks (2.5 ~ 3.3 V) |
P |
| 8 | IOVCC | Low voltage power supply for interface logic circuits (1.65 ~ 3.3 V) |
P |
| 9 | TE | Tearing effect output pin to synchronize MPU to frame writing, activated by S/W command. When this pin is not activated, this pin is low. If not used, open this pin. |
O |
| 10 | CS | Chip select signal. | I |
| 11 | D/CX(SCL) | (D/CX): This pin is used to select “Data or Command” in the parallel interface. When DCX = 1, data is selected. When DCX = 0, command is selected. (SCL): This pin is used as the serial interface clock in 3-wire 9-bit/4-wire 8-bit serial data interface. If not used, this pin should be connected to VDDI or VSS. |
I |
| 12 | WR(SPI_D/C) | (WRX) - 8080-Ⅰ/8080-Ⅱ system: Serves as a write signal and writes data at the rising edge. (D/CX) - 4-line system: Serves as the selector of command or parameter. Fix to VDDI level when not in use. |
I |
| 13 | RD | 8080-Ⅰ/8080-Ⅱ system (RDX): Serves as a read signal and MCU read data at the rising edge. Fix to VDDI level when not in use. |
I |
| 14-29 | DB0~DB15 | 18-bit parallel bi-directional data bus for MCU system and RGB interface mode Fix to VSS level when not in use. | I/O |
| 30 | RESET | This signal will reset the device and must be applied to properly initialize the chip. Signal is active low. |
I |
| 31 | IM0 | Select the MCU interface mode MPU Parallel interface bus and serial interface select If use RGB Interface must select serial interface. * : Fix this pin at VDDI or VSS. |

| 33 | IM2 | ||
| 34 | DB16 | 18-bit parallel bi-directional data bus for MCU system and RGB interface mode Fix to VSS level when not in use. | I/O |
| 35 | DB17 | ||
| 36 | LEDK | Cathode of LED backlight. | P |
| 37 | LEDK | Cathode of LED backlight. | P |
| 38 | LEDA | Anode of LED backlight. | P |
| 39 | SDI(SDA) | When IM[3] : Low, Serial in/out signal. When IM[3] : High, Serial input signal. The data is applied on the rising edge of the SCL signal. If not used, fix this pin at VDDI or VSS. |
I/O |
| 40 | SDO | Serial output signal. The data is outputted on the falling edge of the SCL signal. If not used, open this pin |
