Functions

1

VG

p

LCD driving voltage for segments.
Be aware that: 1.8 = VG < VDD2-0.4V.

2

XVO

p

LCD driving voltage for commons at positive frame.
XV0O is the output of XV0 regulator. XV0S is the feedback of XV0 regulator.
XV0I is the XV0 input of common circuits.
XV0O, XV0I & XV0S should be connected together by ITO.

3

VO

p

LCD driving voltage for commons at negative frame.
V0O is the output of V0 regulator. V0S is the feedback of V0 Regulator.
V0I is the V0 input of common circuits.
Be aware that: V0 = VG > VM > VSS = XV0 (under operation).
V0O, V0I & V0S should be connected together by ITO.

4

VDDA

p

Digital power. If VDD1=VDD2, connect to VDD2 by ITO.
For select pins that are set to be “H”, connect them to this power (use VDD1 for “H”).

5

VDDI

p

Analog power. If VDD1=VDD2, connect to VDD1 by ITO.

6

VSS

8

RST

I

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

9

SCL

I/O

When using I2C interface
D[0] : SCL, serial clock input.
D[1] : SDA_IN, serial input data.
D[3:2] : SDA_ OUT, serial data acknowledge for the I2C interface.
D[4] : SCL, serial clock input.
D[7:5] : fix to “H” by VDD1.
D0 and D4 must be connected together for SCL.
D1 to D3 must be connected together for SDA.
Note : SA[1:0] = CS[1:0], I2C slave address bits of ST7525. Must connect to VDD1 or VSS1.

FAQ

1.What is RAM Interface

Answer :The external RAM is used to store display data( text, graphic and external CG data ). It can be freely allocated to the memory area( 8 K byte max ).

2.Can graphic LCD module display characters?

A graphic LCD display module is typically required when the display of more than just text is required. Many of the LCD controllers on board also include a CGROM (character generator ROM) to be able to easily use character as well as graphics. 

3.What can graphic LCD display ?

This Graphic LCD display module is 160x64 graphic mode --or-- Character Generator mode (Character font) optional.

4.What are the precautions in use of LCD Modules?

(1)Avoid applying excessive shocks to the module or making any alterations or modifications to it.

(2)Don’t make extra holes on the printed circuit board, modify its shape or change the components of LCD module.

(3)Don’t disassemble the LCM.

(4)Don’t operate it above the absolute maximum rating.

(5)Don’t drop, bend or twist LCM.

(6)Soldering: only to the I/O terminals.
