| Pin No. | Symbol | Level | Opis | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | /CS1B | I | This is the chip select signal. | |||||||||||||||
| 2 | /RES | I | When RES is set to “L”, the setting are initialized. | |||||||||||||||
| 3 | A0 | I | This is connect to the least significant bit of the normal MPU address bus, and it determines whether the data bits are data or command. A0 = “H”: Indicates that D0 to D7 are display data. A0 = “L”: Indicates that D0 to D7 are control data. |
|||||||||||||||
| 4 | /WR(R/W) | I | • When connected to 8080 series MPU, this pin is treated as the “/WR” signal of the 8080 MPU and is LOW-active. The signals on the data bus are latched at the rising edge of the /WR signal. • When connected to 6800 series MPU, this pin is treated as the “R/W” signal of the 6800 MPU and decides the access type : When R/W = “H”: Read. When R/W = “L”: Write. |
|||||||||||||||
| 5 | /RD(E) | I |
• When connected to 8080 series MPU, this pin is treated as the “/RD” signal of the 8080 MPU and is LOW-active. |

| 15 | VSS | Power supply | Ground | |||||||||||||||
| 16 | VOUT | O | DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD | |||||||||||||||
| 17 | CAP3P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal. | |||||||||||||||
| 18 | CAP1N | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal. | |||||||||||||||
| 19 | CAP1P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal. | |||||||||||||||
| 20 | CAP2P | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal. | |||||||||||||||
| 21 | CAP2N | O | DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal. | |||||||||||||||
| 22~26 | V4~V0 | Power supply | This is a multi-level power supply for the liquid crystal drive. | |||||||||||||||
| 27 | VR | I | Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider. | |||||||||||||||
| 28 | C86 | I | This is the MPU interface selection pin. C86 = “H”: 6800 Series MPU interface. C86 = “L”: 8080 Series MPU interface |
|||||||||||||||
| 29 | P/S | I | This is the parallel data input/serial data input switch terminal. P/S = “H”: Parallel data input. P/S = “L”: Serial data input. The following applies depending on the P/S status:
/RD (E) and /WR (R/W) are fixed to either “H” or “L”. With serial data input, It is impossible read data from RAM |
