Operation of the SCF574X
The SCF574X display consists of a CMOS IC containing con-
trol logic and drivers for four 5x7 characters. Theres compo-
nents are assembled in a compact plastic package.
Individual LED dot addressability allows the user great free-
dom in creating special characters or mini-icons.
The serial data interface provides a highly efficient intercon-
nection between the display and the mother board. The
SCF574X requires only three lines as compared to 14 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
internal RAM. Asynchronously the RAM is read by the charac-
ter multiplexer at a strobe rate that results in a flicker free dis-
play. Figure 6 shows the three functional areas of the IC.
These include: the input serial data register and control logic,
a 140 bits two port RAM, and an internal multiplexer/display
driver.
