Interface Definition
| Pin No. | Symbol | Level | Description |
| 1 | CS1 | H/L | Chip select signal |
| 2 | RST | H/L | Chip reset signal |
| 3 | A0 | H/L | Register selection input H : Indicate that D0 to D7 are display data. L:Indicate that D0 to D7 are control data |
| 4 | WR(R/W) | H/L | 8080 series: Write signal 6800 series: Read or Write signal |
| 5 | RD(E) | H/L | 8080 series: Read signal 6800 series: Enable signal |
| 6–13 | D0-D5 D6(SCL) D7(SI) |
H/L | This is an 8-bit bi-directional data bus that connects to an
8-bit or 16-bit standard MPU data bus. When the serial interface (SPI-4) is selected (P/S = “L”) : D7 : serial data input (SI) ; D6 : the serial clock input (SCL). D0 to D5 should be connected to VDD or floating. |
| 14 | VDD | — | Supply voltage for logic |
| 15 | VSS | — | Ground |
| 16 | VOUT | — | Power for LCD |
| 17 | C3+ | — | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal. |
| 18 | C1- | — | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal. |
| 19 | C1+ | — | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal. Reset signal. |
| 20 | C2+ | — | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal. |
| 21 | C2- | — | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal. Chip select. |
| 22-26 | V4-V0 | — | This is a multi-level power supply for the liquid crystal drive. |
| 27 | VR | — | Contrast adjustment input. |
| 28 | C86 | H/L | C86 = “H”: 6800 Series MPU interface. C86 = “L”: 8080 Series MPU interface. |
| 29 | PS | H/L | P/S = “H”: Parallel interface P/S = “L”: Serial interface |
| 30 | IRS | H/L | RS = “H”: Use the internal resistors IRS = “L”: Do not use the internal resistors. |
