The SCD558X requires only 4 lines as compared to 15 for an
equivalent 8 character parallel input part.
The on-board CMOS IC is the electronic heart of the display.
The IC accepts decoded serial data, which is stored in the
internal RAM . Asynchronously the RAM is read by the char-
acter multiplexer at a strobe rate that results in a icker free
display. Figure 8 shows the three functional areas of the IC.
These include: the input serial data register and control
logic, a 200 bits two port RAM, and an internal multiplexer/
display driver.
Operation of the SCD558X
The SCD558X display consists of a CMOS IC containing con-
trol logic and drivers for eight 5x5 characters. These compo-
nents are assembled in a compact (38 mm x 10 mm) plastic
package.
Individual LED dot addressablity allows the user great free-
dom in creating special characters or mini-icons. The User
Denable Character Set Examples illustrate 200 different
character and symbol possibilities.
The use of a serial data interface provides a highly efcient
interconnection between the display and the mother board.
