Description

1

/CS1

This is the chip select. When /CS1=”L” and CS2=”H”, Then the chip select becomes active data/command I/O is enabled.

2

CS2

3

/RES

Reset pin.

4

A0

A0=”H”：indicate that D0 toD7 are display data.

A0=”L”：indicate that D0 toD7 are control data.

5

R/W

Read/Write control pin.

V1

LCD driver supply voltages. The voltage determined by LCD cell is impedance-converted by a resistive driver or an operation amplifier for application. Voltages should be the following relationship:

V0≥V1≥V2≥V3≥V4≥VSS

24

V2

LCD driver supply voltages. The voltage determined by LCD cell is impedance-converted by a resistive driver or an operation amplifier for application. Voltages should be the following relationship:

V0≥V1≥V2≥V3≥V4≥VSS

29

P/S

This is the parallel data input/serial data input switch terminal.

30

IRS

This terminal selects the resistors for the V0 voltage level adjustment.
