AYRINTILAR
Arayüz Pin Fonksiyonlari
Pin No. | Symbol | TANIM | ||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
1 | ESD GND | Electro-Static discharge | ||||||||||||||||||||
2 | VG | VG is the power of SEG-drivers | ||||||||||||||||||||
3 | XV0 | Negative operating voltage of COM-drivers | ||||||||||||||||||||
4 | V0 | Positive operating voltage of COM-drivers | ||||||||||||||||||||
5 | VM | VM is the non-select voltage level of COM-drivers. | ||||||||||||||||||||
6 | VDDA | Power supply | ||||||||||||||||||||
7 | VSS | Ground | ||||||||||||||||||||
8 | VD1 | Digital power source selection. | ||||||||||||||||||||
9 | VDDI | VDD1 is the power of interface I/O circuit | ||||||||||||||||||||
10 | CSB | Chip select input pin CSB=“L”: This chip is selected and the MPU interface is active CSB=“H”: This chip is not selected and the MPU interface is disabled (D[7:0] are high impedance) |
||||||||||||||||||||
11 | IF3 | These pins select interface operation mode.
|
||||||||||||||||||||
12 | IF2 | |||||||||||||||||||||
13 | IF1 | |||||||||||||||||||||
14 | RSTB | Reset input pin. When RSTB is “L”, internal initialization procedure is executed. | ||||||||||||||||||||
15 | /RD(E) | Read / Write execution control pin. (This pin is only used in parallel interface)
|
||||||||||||||||||||
16~23 | D7~D0 | The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance. If using serial interface: D0 is the SDA signal in 4-Line & 3-Line interface. D1 is the A0 signal in 4-Line interface |
||||||||||||||||||||
24 | /WR/(R/W) | Read / Write execution control pin. (This pin is only used in parallel interface
|
||||||||||||||||||||
25 | A0(SCL) | The function of this pin is different in parallel and serial interface In parallel interface: A0 is register selection input A0 = "H": inputs on data bus are display data A0 = "L": inputs on data bus are command In serial interface: this pad will be used as SCL (serial-clock) input |
||||||||||||||||||||
26 | ESD GND | Electro-Static discharge |
