| Pin No. | Symbol | Level | Description |
|---|---|---|---|
| 1 | P/S | I | This is the parallel data input/serial data input switch terminal. |
| 2 | C86 | I | This is the MPU interface switch terminal. |
| 3 | VR | I | Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider. |
| 4~8 | V0~V4 | Power supply | This is a multi-level power supply for the liquid crystal drive. |
| 9 | CAP2N | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal. |
| 10 | CAP2P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal. |
| 11 | CAP1P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal. |
| 12 | CAP1N | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal. |
| 13 | CAP3P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal. |
| 14 | VOUT | O | DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD |
| 15 | VSS | Power supply | Ground |
| 16 | VDD | Power supply | Power supply |
| 17~24 | D7~D0 | I/O | This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus. |
| 25 | /RD(E) | I | The data bus is in output status when this signal is “L” |
| 26 | /WR(R/W) | I | The data bus are latched at the rising edge of the WR signal |
| 27 | A0 | I | This is connect to the least significant bit of the Norman MPU address bus, and it determines whether the data bits are data or a command. |
| 28 | /RES | I | When RES is set to “L”, the setting are initialized. |
| 29 | /CS1 | I | This is the chip select signal. |
