Interface Pin Definition
| PIN | SYMBOL | Descriptions |
| 1 | GND | Ground of Logic Circuit |
| 2 | VDD | Power Supply for Logic |
| 3 | SCK | Serial clock input. |
| 4 | SDA | Serial data input. |
| 5 | RST | This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin pull high during normal operation. |
| 6 | DC | This pin is Data/Command control pin. When the pin is pulled high and serial interface mode is selected, the data at SDIN will be interpreted as data. When it is pulled low, the data at SDIN will be transferred to the command register. |
| 7 | CS | Chip Select. Chip is selected when CS0 = “L” . |

Note 1: All the above voltages are on the basis of “VSS = 0V”.
Note 2: When this module is used beyond the above absolute maximum ratings, permanent breakage of the module may occur. Also, for normal operations, it is desirable to use this module under the conditions according to Section 3. “Optics & Electrical Characteristics”. If this module is used beyond these conditions, malfunctioning of the module can occur and the reliability of the module may deteriorate.
Note 3: The defined temperature ranges do not include the polarizer. The maximum withstood
temperature of the polarizer should be 80.C.
