BACKLIGHT

Using the LED backlight requires a current source or external current-limiting resistor. Forward

voltage for yellow/green backlight is 3.9~4.2V and for white LED backlight is 3.0~3.6V. Please take

care of derating for Ta>+25°C.

Note: Do never connect backlight directly to 5V; this may destroy backlight immediately !

CONTRAST ADJUSTMENT

Pin 3 requires driving voltage for contrast

VEE. Adjustment can be done by external

potentiometer for example. The capacitor

is for a better startup behaviour.

Note: In contrast to many other

dotmatrix lcd modules input is

supplied with VDD level here !

CREATING YOUR OWN CHARACTERS

All these character display modules got the feature to create 8 own characters (ASCII Codes 0..7) in

addition to the 240 ROM fixed codes.

1.) The command "CG RAM Address Set"

defines the ASCII code (Bit 3,4,5) and the

dot line (Bit 0,1,2) of the new character.

Example demonstrates creating ASCII

code $00.

2.) Doing 8 times the write command "Data

Write" defines line by line the new

character. 8th. byte stands for the cursor

line.

3.) The newly defined character can be used as a "normal" ASCII code (0..7); use with "DD RAM

Address Set" and "Data Write".

CHARACTER SET

A full character set is built-in already.

Additionally to that 8 more characters can

be defined individually.

SERIAL MODE

Factory setting for interface is parallel with 4 bit or 8 bit data bus. Alternatively the module can be used

with serial data stream. For that, solder link SPI has to be closed. Specification for serial

operation mode is described in user manual for SSD1803:

http://www.lcd-module.de/fileadmin/eng/pdf/zubehoer/ssd1803_2_0.pdf

all dimensions are in mm

DRIVING WITH 5V-SYSTEMS

The supply voltage of the display is necessarily 3.3V.

If a 5V-system is used, the level have to be adapted.

For example you can use a bidirectional levelshifter

(e.g. PS 74LVC4245A), like shown in the opposite

figure.

COMPATIBILITY WITH EA DIP204-4

The displays of EA DIP203 and EA DIP204 series are

electrically and mechanically identical to each other

running with 3.3V supply mode.

Merely a 5V supply is not acceptable with the new

EA DIP203 series.

Note:

LC-Displays are generally not suited to wave or reflow

soldering. Temperatures of over 80°C can cause lasting

demage.
