DESCRIPTION
These Programmable Displays are four digit display sys-
tem modules. The characters are
5.08 mm by 3.56 mm (0.20" by 0.14") (PD243X),
6.86 mm by 5.08 mm (0.27" by 0.20") (PD353X), and
11.43 mm by 6.86 mm (0.45" by 0.27") (PD443X)
5 x 7 dot matrix arrays constructed with the latest solid
state technology in light emitting diodes. Driving and
controlling the LED arrays is a silicon gate CMOS inte-
grated circuit. This integrated circuit provides all neces-
sary LED drivers and complete multiplexing control
logic.
Additionally, the IC has the necessary ROM to decode
128 ASCII alphanumeric characters and enough RAM to
store the display’s complete four digit ASCII message
with special attributes. These attributes, all software pro-
grammable at the user’s discretion, include a lamp test,
brightness control, displaying cursors, alternating cursors
and characters, and flashing cursors or characters.
The CMOS IC also incorporates special interface control
circuitry to allow the user to control the module as a fully
supported microprocessor peripheral. The module, under
internal or external clock control, has asynchronous
read, write, and memory clear over an eight bit parallel,
TTL compatible, bi-directional data bus. Each module is
fully encapsulated within a package
25.4 x 17.8 x 5.08 mm (1.0" x 0.7" x 0.2") (PD253X),
35.6 x 18.3 x 7.24 mm (1.4" x 0.72" x 0.285") (PD353X),
and
38.1 x 20.8 x 7.24 mm (1.5" x 0.82" x 0.285") (PD443X).
The standard 20 pin DIP construction with two rows
spaced at 15.2 mm (0.6") on 2.54 mm (0.1") centers is
wave solderable.

22, and 23 for further details on handling and assembling
OSRAM Programmable Displays.
