Operation of the SCDV554X
The SCDV554X display consists of a CMOS IC containing con-
trol logic and drivers for four 5x5 characters. These components
are assembled in a compact plastic package.
Individual LED dot addressablity allows the user great freedom
in creating special characters or mini-icons. The User Denable
Character Set examples illustrate 200 different character and
symbol possibilities.
The serial data interface provides a highly efcient interconnec-
tion between the display and the mother board. The SCDV554X
requires only four lines as compared to 15 for an equivalent four
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 inter-
nal RAM. Asynchronously the RAM is read by the character
multiplexer at a strobe rate that results in a icker free display.
Figure 7 shows the three functional areas of the IC. These
include: the input serial data register and control logic, a 100
bits two port RAM, and an internal multiplexer/display driver.
