AYRINTILAR
Arayüz Pin Fonksiyonlari
| No. | Sembol | Fonksiyon |
|---|---|---|
| 1 | NC | No connection |
| 2 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. When charge pump is enabled, a capacitor should be connected between this pin and VSS. |
| 3 | VCOMH | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
| 4 | IREF | This is segment output current reference pin. When external IREF is used, a resistor should be connected between this pin and VSS to maintain the IREF current at 30uA. |
| 5 | D7 | These are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN. When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL. |
| 6 | D6 | |
| 7 | D5 | |
| 8 | D4 | |
| 9 | D3 | |
| 10 | D2 | |
| 11 | D1 | |
| 12 | D0 | |
| 13 | E/RD# | This pin is MCU interface input. When 6800 interface mode is selected, 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 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS. |
| 14 | R/W# | This 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 (i.e. connect to VDD) 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 or I2C interface is selected, this pin must be connected to VSS. |
| 15 | D/C# | This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data. When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register. |
| 16 | RES# | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation. |
| 17 | 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 (active LOW). |
| 18 | NC | No connection |
| 19 | BS2 | MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2, BS1 are pin select Note (1) 0 is connected to VSS (2) 1 is connected to VDD |
| 20 | BS1 | |
| 21 | VDD | Power supply pin for core logic operation. This is a voltage supply pin. It must be connected to external source. |
| 22~29 | NC | No connection |
| 30 | VSS | Ground pin. It must be connected to external ground. |
| 31 | NC | No connection |
