DESCRIPTION
These Programmable Displays are four digit display sys-
tem modules. The characters are 0.20" by 0.14"
(PD243X), 0.27" by 0.20" (PD353X), and 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 integrated circuit. This integrated circuit provides
all necessary 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
programmable at the user’s discretion, include a lamp
test, brightness control, displaying cursors, alternating
cursors and characters, and flashing cursors or charac-
ters.
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 asynchro-
nous read, write, and memory clear over an eight bit par-
allel, TTL compatible, bi-directional data bus. Each
module is fully encapsulated within a package 1.0" x 0.7"
x 0.2" (PD253X), 1.4" x 0.72" x 0.285" (PD353X), and 1.5"
x 0.82" x 0.285" (PD443X). The standard 20 pin DIP con-
struction with two rows spaced at 0.6" on 0.1" centers is
wave solderable.

19, 22, and 23 for further details on handling and assem-
bling OSRAM Programmable Displays.
