Pin Configuration
| Pin No | Pin Name | Description |
|---|---|---|
| 1 | IRS | This terminal selects the resistors for the V0 voltage level adjustment IRS='H': Use the internal resistors IRS='L': Do not use the internal resistors |
| 2 | PS | This is the parallel data input/serial data input switch terminal P/S = 'H': Parallel data input P/S = 'L': Serial data input |
| 3 | C86 | This is the MPU interfaces switch terminal C86 = 'H': 6800 Series MPU interface C86 = 'L': 8080 Series MPU interface |
| 4 | VR | Voltage adjustment pad. Applies voltage between V0 and VSS using a resistive divider. |
| 5 | V0 | LCD driver suppliers voltages. The voltage determined by the LCD cell is impedance-converted by a resistive driver or an operation amplifier for application. Voltages should be according to the following relationship: |
| 5 | V4 | |
| 5 | V3 | |
| 5 | V2 | V0 ≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ VSS2 |
| 5 | V1 | |
| 10 | CAP2- | Capacitor 2- pad for internal DC/DC voltage converter |
| 11 | CAP2+ | Capacitor 2+ pad for internal DC/DC voltage converter |
| 12 | CAP1+ | Capacitor 1+ pad for internal DC/DC voltage converter |
| 13 | CAP1- | Capacitor 1- pad for internal DC/DC voltage converter |
| 14 | CAP3+ | Capacitor 3+ pad for internal DC/DC voltage converter |
| 15 | VOUT | DC/DC voltage converter output |
| 16 | VSS | Ground. These pads must be connected to each other. |
| 17 | VDD | Power supply output for pad option |
| 18-25 | D7~D0 | When the serial interface is selected(P/S='L'), then D7 serves as the serial data input terminal (SI) and D6 serves as the serial clock input terminal (SCL). When the serial interface is selected, fix D0~D5 pads to VDD or VSS level. When the chip select is inactive, D0 to D7 are set to high impendence. |
| 26 | /RD(E) | This is used as an enable clock input of the 6800 series MPU |
| 27 | R/W | When R/W = 'H': Read When R/W = 'L': Write |
| 28 | A0 | A0='H': Indicate that D0 to D7 are display data A0='L': Indicate that D0 to D7 are control data |
| 29 | /RES | When /RES is set to 'L', the settings are initialized. The reset operation is performed by the /RES signal level |
| 30 | /CS1 | This is the chip select signal. |
