Operation of the SCD5510XA
The SCD5510XA display consists of a CMOS IC containing control
logic and drivers for eight 5 x 5 characters. These components are
assembled in a compact (38 mm x 10 mm) plastic package.
Individual LED dot addressablity allows the user great freedom in
creating special characters or mini-icons. The User Definable
Character Set Examples illustrate 200 different character and sym-
bol possibilities.
The use of a serial data interface provides a highly efficient inter-
connection between the display and the mother board. The
SCD5510XA requires only 4 lines as compared to 15 for an equiv-
alent 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 character multiplexer at a
strobe rate that results in a flicker free display. Figure Row and
Column Location“ (page 9) shows the three functional areas of the
IC. These include: the input serial data register and control logic, a
250 bits two port RAM, and an internal multiplexer/display driver.
