Specifications

Interface Pin Function

Pin No.

Symbol

I/O

Description

VG is the power of SEG-drivers.

XV0

Negative operating voltage of COM-drivers.

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.

VM is the non-select voltage level of COM-drivers.

VDDA

Analog power for internal booster.

VSS

Ground

VD1

VD1I is the power source of digital circuits.

VDDI

Power of interface I/O circuit.

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).

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.

IF2

IF1

RSTB

Input

Reset input pin. When RSTB is “L”, internal initialization procedure is executed.

/RD(E)

Input

Read / Write execution control pin. (This pin is only used in parallel interface)

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

No connection

/WR(R/W)

Input

Read / Write execution control pin. (This pin is only used in parallel interface)

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
