4-Character 5 x 7 Dot Matrix TM Alphanumeric Programmable Display with Built-in CMOS Control Functions Lead (Pb) Free Product - RoHS Compliant PD243X, PD353X, PD443X PD353X PD443X PD243X DESCRIPTION FEATURES Four Dot Matrix Characters in High Efficiency Red, These Programmable Displays are four digit display sys- Red, and Bright Green tem modules. The characters are - PD2435/6/7, 5.08 mm (0.200 ) High 5.08 mm by 3.56 mm (0.20 by 0.14 ) (PD243X), - PD3535/6/7, 6.86 mm (0.270 ) High 6.86 mm by 5.08 mm (0.27 by 0.20 ) (PD353X), and - PD4435/6/7, 11.43 mm (0.45 ) High 11.43 mm by 6.86 mm (0.45 by 0.27 ) (PD443X) Built-in Memory, Decoders, Multiplexer and Drivers 5 x 7 dot matrix arrays constructed with the latest solid Wide Viewing Angle, X Axis 55, Y Axis 65 state technology in light emitting diodes. Driving and Categorized for Luminous Intensity controlling the LED arrays is a silicon gate CMOS inte- 128 Character ASCII Format (Upper and Lower Case grated circuit. This integrated circuit provides all neces- Characters) sary LED drivers and complete multiplexing control 8 Bit Bidirectional Data BUS logic. READ/WRITE Capability Additionally, the IC has the necessary ROM to decode Dual In-Line Package Configuration, 15.2 mm (0.600 ) 128 ASCII alphanumeric characters and enough RAM to Wide, store the displays complete four digit ASCII message 2.54 mm (0.100 ) Pin Centers with special attributes. These attributes, all software pro- End-Stackable Package grammable at the users discretion, include a lamp test, Internal or External Clock brightness control, displaying cursors, alternating cursors Built-in Character Generator ROM and characters, and flashing cursors or characters. TTL Compatible Easily Cascaded for Multidisplay Operation The CMOS IC also incorporates special interface control Less CPU Time Required circuitry to allow the user to control the module as a fully Software Controlled Features: supported microprocessor peripheral. The module, under - Programmable Highlight Attribute (Blinking, internal or external clock control, has asynchronous Non-Blinking) read, write, and memory clear over an eight bit parallel, - Asynchronous Memory Clear Function TTL compatible, bi-directional data bus. Each module is - Lamp Test fully encapsulated within a package - Display Blank Function 25.4 x 17.8 x 5.08 mm (1.0 x 0.7 x 0.2 ) (PD253X), - Single or Multiple Character Blinking Function 35.6 x 18.3 x 7.24 mm (1.4 x 0.72 x 0.285 ) (PD353X), - Programmable Intensity (Three Brightness Levels) and Extended Operating Temperature Range: 38.1 x 20.8 x 7.24 mm (1.5 x 0.82 x 0.285 ) (PD443X). PD243X, PD353X: 40C to +85C The standard 20 pin DIP construction with two rows PD443X: 40C to +70C spaced at 15.2 mm (0.6 ) on 2.54 mm (0.1 ) centers is wave solderable.
