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.
