|---|---|---|---|
| 1 | VSS | 0V | Ground |
| 2 | VDD | 5.0V | Power Supply |
| 3 | VO | (Variable) | Operating voltage for LCD |
| 4 | A0 | H/L | H : Data L : Instruction |
| 5 | R/W | H/L | Read/Write (R/W) signal for the 68-type microcontroller 68-type microcotroller is selected as the host microcontroller, this pin should be connected to the R/W output of the microcontroller. A HIGH level on this pin indicates that the microcontroller intends to read from the SBN1661G_X series. A LOW level on this pin indicates that the microcontroller intends to write to the SBN1661G_X series. |
| 6 | CS1 | H/L | Enable signal (E) for the 68-type microcontroller. 68-type microcotroller is selected as the host microcontroller, this pin should be connected to the ENABLE output of the microcontroller. A HIGH level on this pin indicates that the microcontroller intends to select the SBN1661G_X series. |
| 7 | DB0 | H/L | Bi-direction, tri-state 8-bit parallel data bus for interface with a host microcontroller. This data bus is for data transfer between the host microcontroller and the SBN1661G_X. |
| 8 | DB1 | H/L | Bi-direction, tri-state 8-bit parallel data bus for interface with a host microcontroller. |
| 9 | DB2 | H/L | This data bus is for data transfer between the host microcontroller and the SBN1661G_X. |
| 10 | DB3 | H/L | Bi-direction, tri-state 8-bit parallel data bus for interface with a host microcontroller. |
| 11 | DB4 | H/L | This data bus is for data transfer between the host microcontroller and the SBN1661G_X. |
| 12 | DB5 | H/L | Bi-direction, tri-state 8-bit parallel data bus for interface with a host microcontroller. |
| 13 | DB6 | H/L | This data bus is for data transfer between the host microcontroller and the SBN1661G_X. |
