Pin功能定義
| No. | 符號 | 功能說明 | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | N.C. | The N.C. pin between function pins are reserved for compatible and flexible design. | ||||||||||
| 2 | VSS | Ground. | ||||||||||
| 3 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. |
||||||||||
| 4 | VCOMH | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
||||||||||
| 5 | VLSS | Analog system ground pin. | ||||||||||
| 6~13 | D7~D0 | These pins are bi-directional data bus connecting to the MCU data bus. Unused pins are recommended to tie LOW. (Except for D2 pin in SPI mode) |
||||||||||
| 14 | E/RD# | This pin is MCU interface input. When interfacing to a 6800-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 chip is selected. When connecting to an 8080-microprocessor, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial interface is selected, this pin E(RD#) must be connected to VSS. |
||||||||||
| 15 | R/W# | This pin is read / write control input pin connecting to the MCU interface. When interfacing to a 6800-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW. When 8080 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 chip is selected. When serial interface is selected, this pin R/W (WR#) must be connected to VSS. |
||||||||||
| 16 | BS0 | MCU bus interface selection pins. Select appropriate logic setting as described in the following table.
(1) 0 is connected to VSS (2) 1 is connected to VDDIO |
||||||||||
| 17 | BS1 | |||||||||||
| 18 | D/C# | 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. |
||||||||||
| 19 | CS# | This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW. | ||||||||||
| 20 | RES# | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation. |
||||||||||
| 21 | FR | This pin is No Connection pins. Nothing should be connected to this pin. This pin should be left open individually. | ||||||||||
| 22 | IREF | This pin is the segment output current reference pin. A resistor should be connected between this pin and VSS to maintain the current around 10uA. |
||||||||||
| 23 | N.C. | The N.C. pin between function pins are reserved for compatible and flexible design. | ||||||||||
| 24 | VDDIO | Power supply for interface logic level. It should be matched with the MCU interface voltage level. | ||||||||||
| 25 | VDD | Power supply pin for core logic operation. A capacitor is required to connect between this pin and VSS. | ||||||||||
| 26 | VCI | Low voltage power supply. VCI must always be equal to or higher than VDD and VDDIO. |
