Interface Pin Function

Pin No. Symbol I/O Description
1 VG P VG is the power of SEG-drivers.
2 XV0 P Negative operating voltage of COM-drivers.
3 V0 P Positive operating voltage of COM-drivers.
V0O is the output of the positive Vop generator.
V0I is the positive Vop supply of LCD drivers.
V0S is the sensor of the positive Vop generator.
V0O, V0I & V0S should be separated on ITO and be connected together by FPC.
4 VM P VM is the non-select voltage level of COM-drivers.
5 VDDA P Analog power for internal booster.  
6 VSS P Ground
7 VD1 P VD1I is the power source of digital circuits.
8 VDDI P Power of interface I/O circuit.
9 CSB Input 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).
10 IF3 Input These pins select interface operation mode.
IF3 IF2 IF1 MPU interface type
H H L 80 series 8-bit parallel
H L L 68 series 8-bit parallel
L H H 8-bit serial (4-Line)
L H L 9-bit serial (3-Line)
Note: Refer to “Interface Selection” for detailed information.
11 IF2
12 IF1
13 RSTB Input Reset input pin. When RSTB is “L”, internal initialization procedure is executed.
14 /RD(E) Input Read / Write execution control pin. (This pin is only used in parallel interface)
15 D7 I/O 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
16 D6
17 D5
18 D4
19 D3
20 D2
21 D1
22 D0
23 NC   No connection
24 /WR(R/W) Input Read / Write execution control pin. (This pin is only used in parallel interface)
25 A0(SCL) Input 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 VSS P Ground
