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.

PD243X, PD353X, PD443X Functional Description The block diagram includes 5 major blocks and internal registers (indicated by dotted lines). Display Memory consists of a 5 x 8 bit RAM block. Each of the four 8-bit words holds 7-bits of ASCII data (bits D0–D6) and an attribute select bit (Bit D6). The fifth 8-bit memory word is used as a control word register. A detailed description of the control register and its functions can be found in the Control Word section.
PAGE 9
PD243X, PD353X, PD443X There are five registers within the display. Four of these registers are used to hold the ASCII/attribute code of the four display characters. The fifth register is the Control Word, which is used to blink, blank, clear, or dim the entire display, or to change the presentation (attributes) of individual characters. Control Word When address bit A2 is taken low, the Control Word is accessed. The same Control Word appears in all four of the lower address spaces of the display.

PD243X, PD353X, PD443X How to Load Information Into the Display Information loaded into the display can be either ASCII data or Control Word data. The following procedure (see also Typical Loading Sequence) will demonstrate a typical loading sequence and the resulting visual display. The word STOP is used in all of the following examples. Set Brightness Step 1 Set the brightness level of the entire display to your preference (example: 100%) Load Four Characters Step 2 Load an “S” in the left hand digit.

PD243X, PD353X, PD443X Electrical and Mechanical Considerations The CMOS IC of the display is designed to provide resistance to both Electrostatic Discharge Damage and Latch Up due to voltage or current surges. Several precautions are strongly recommended to avoid overstressing these built-in safeguards. Power Down Sequence 1.Float all active signals by tri-stating the inputs to the display. 2.Turn off the power to the display.

PD243X, PD353X, PD443X Post Solder Cleaning Procedures The least offensive cleaning solution is hot D.l. water (60 °C) for less than 15 minutes. Addition of mild saponifiers is acceptable. Do not use commercial dishwasher detergents. For faster cleaning, solvents may be used. Carefully choose the solvents as some may chemically attack the package. Maximum exposure should not exceed two minutes at elevated temperatures.
