Pin_SIGNAL
| Pin No. | Pin Name | Function |
| 1 | VDD | Power supply |
|
2 |
P/S |
This pin configures the interface to be parallel mode or serial mode. P/S = “H”: Parallel data input/output. P/S = “L”: Serial data input. |
|
3 |
C86 |
This is the MPU interface selection pin. C86 = “H”: 6800 Series MPU interface. C86 = “L”: 8080 Series MPU interface. |
|
4~8 |
V5~V1 |
This is a multi-level power supply for the liquid crystal drive. The voltage Supply applied is determined by the liquid crystal cell, and is changed through the use of a resistive voltage divided or through changing the impedance using an op. amp. Voltage levels are determined based on Vss, and must maintain the relative magnitudes shown below. V1 ≧V2 ≧V3 ≧V4 ≧V5 |
| 9 | C2+ |
When internal DC-DC voltage converter is used, external capacitor is connected between these pins. |
| 10 | C2- | |
| 11 | C1+ | |
| 12 | C1- | |
| 13 | C3+ | |
| 14 | VOUT | Positive voltage supply pin of the chip. |
| 15 | VSS | Negative power supply,0V |
| 16~23 | D7~D0 |
8bit Date bus, D7 : serial data input (SI) ; D6 : the serial clock input (SCL) |
|
24 |
E |
• When connected to 8080 series MPU, this pin is treated as the “/RD” signal of the 8080 MPU and is LOW-active. The data bus is in an output status when this signal is “L”. • When connected to 6800 series MPU, this pin is treated as the “E” signal of the 6800 MPU and is HIGH-active. This is the enable clock input terminal of the 6800 Series MPU. |
| 25 | R/W | When R/W = “H”: Read. When R/W = “L”: Write. |
|
26 |
A0 |
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 |
