Interface Pin Function
| Pin No. | Symbol | Description |
|---|---|---|
| 1 | ESD GND | Electro-Static discharge |
| 2 | VG | VG is the power of SEG-drivers |
| 3 | XV0 | Negative operating voltage of COM-drivers |
| 4 | V0 | Positive operating voltage of COM-drivers |
| 5 | VM | VM is the non-select voltage level of COM-drivers |
| 6 | VDDA | Power supply |
| 7 | VSS | Ground |
| 8 | VD1 | Digital power source selection |
| 9 | VDDI | VDD1 is the power of interface I/O circuit |
| 10 | CSB | Chip select input pin CSB=“L”: This chip is selected and the MPU interface is active CSB=“H”: This chip is not selected and the MPU interface is disabled (D[7:0] are high impedance) |
| 11 12 13 |
IF3 IF2 IF1 |
These pins select interface operation mode Note: Refer to “Interface Selection” for detailed information |
| 14 | RSTB | Reset input pin. When RSTB is “L”, internal initialization procedure is executed |
| 15 | /RD(E) | Read / Write execution control pin. (This pin is only used in parallelinterface) This pin is not used in serial interfaces and should be connected to VDD1 |
| 16~23 | D7~D0 | The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance If using serial interface: D0 is the SDA signal in 4-Line & 3-Line interface D1 is the A0 signal in 4-Line interface |
| 24 | /WR/(R/W) | Read / Write execution control pin. (This pin is only used in parallel interface) This pin is not used in serial interfaces and should be connected to VDD1 |
| 25 | A0(SCL) | The function of this pin is different in parallel and serial interface In parallel interface: A0 is register selection input A0 = "H": inputs on data bus are display data A0 = "L": inputs on data bus are command In serial interface: this pad will be used as SCL (serial-clock) input |
| 26 | ESD GND | Electro-Static discharge |
