Interface Definition
| PIN No. | Symbol | Description |
|---|---|---|
| 1 | X(L) | Touch panel control pin |
| 2 | Y(U) | Touch panel control pin |
| 3 | X(R) | Touch panel control pin |
| 4 | Y(D) | Touch panel control pin |
| 5 | GND | Ground |
| 6 | IOVCC | Power supply for LCM (2.8V–3.3V) |
| 7 | VCI | Power supply for LCM (2.8V–3.3V) |
| 8 | FMARK | 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. |
| 9 | CS / SPI CS | Chip select pin ("Low" enable) |
| 10 | RS / SPI SCL / SCK |
This pin is used to select "Data or Command" in the parallel interface or serial data interface. Parallel: When RS= '1', data is selected. When RS= '0', command is selected. Serial: This pin is used as serial interface clock in 3-wire 9-bit / 4-wire 8-bit serial data interface. If not used, this pin should be connected to IOVCC or GND. |
| 11 | WR / A0 |
Serves as a write signal and writes data at the rising edge. 4-line system (D/CX): Serves as command or parameter select. Fix to IOVCC level when not in use. |
| 12 | RD |
Serves as a read signal and MCU reads data at the rising edge. Fix to IOVCC level when not in use. |
| 13 | SPI_SDI / SDA |
Serial input signal. The data is applied on the rising edge of the SCL signal. If not used, fix this pin at IOVCC or GND. |
| 14 | SPI_SD0 |
Serial output signal. The data is outputted on the falling edge of the SCL signal. If not used, open this pin. |
| 15 | RESET | LCM Reset pin. Signal is active low. |
| 16 | GND | Ground |
| 17–24 | DB0–DB7 | Data bus. Fix to GND level when not in use. |
| 25–32 | DB8–DB15 | Data bus. Fix to GND level when not in use. |
| 33 | A | Anode of Backlight (3.0V–3.4V, Typical: 3.2V) |
| 34–36 | K | Cathode of Backlight |
| 37 | GND | Ground |
