| 1 | VDD | Power supply input |
| 2 | VSS | Ground. |
| 3 | NC | No connection |
| 4~11 | D0~D7 | This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus. |
| 12 | CS# | This pad is the chip select input. When=”L”, then the chip select becomes active, and data/command I/O is enabled. |
| 13 | NC | No Connection |
| 14 | RES# | This is a reset signal input pad. When is set to “L”, the settings are initialized. The reset operation is performed by the signal level. |
| 15 | W/R# | This is a MPU interface input pad. When connected to an 8080 MPU, this is active LOW. This pad connects to the 8080 MPU signal. The signals on the data bus are latched at the rising edge of the signal. |
| 16 | A0 | This is the Data/Command control pad that determines whether the data bits are data or a command. A0=”H”: the inputs at D0 to D7 are treated as display data. A0=”L”: the inputs at D0 to D7 are transferred to the command registers. |
| 17 | R/D# | This is a MPU interface input pad. When connected to an 8080 series MPU, it is active LOW. This pad is connected to the signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”. |
| 18 | NC | No Connection |
| 19 | DISP | Display off when it’s pulled low; Display on when it’s pulled high. |
