DESCRIPTION These Programmable Displays are four digit display system 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 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 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 .
