Pin功能定义
| Pin No. | 符号 | Level | 说明 | ||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | VG | P | VG is the power of SEG-drivers. | ||||||||||||||||||||
| 2 | XV0 | P | Negative operating voltage of COM-drivers. | ||||||||||||||||||||
| 3 | V0 | P | Positive operating voltage of COM-drivers. V0O is the output of the positive Vop generator. V0I is the positive Vop supply of LCD drivers. V0S is the sensor of the positive Vop generator. V0O, V0I & V0S should be separated on ITO and be connected together by FPC. |
||||||||||||||||||||
| 4 | VM | P | VM is the non-select voltage level of COM-drivers. | ||||||||||||||||||||
| 5 | VDDA | P | Analog power for internal booster. | ||||||||||||||||||||
| 6 | VSS | P | Ground | ||||||||||||||||||||
| 7 | VD1 | P | VD1I is the power source of digital circuits. | ||||||||||||||||||||
| 8 | VDDI | P | Power of interface I/O circuit. | ||||||||||||||||||||
| 9 | CSB | Input | 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). |
