This approach allows the user to asynchronously address one of four digits, and load new data without regard to the LED multiplex timing. Figure1 is a block diagram of the DLX2416. The unit consists of 4 (5x7) LEDs and a single CMOS integrated chip. The IC chip contains the column drivers and row drivers, 128 character ROM, four word x7 bit Random Access Memory, oscillator for multiplexing, multiplex counter/decoder, cursor memory, address decoder, and miscellaneous control logic. This application note is intended to serve as a design and appli- cation guide for the DLX2416 alphanumeric Intelligent Displays. The information presented covers device electrical description and operation, considerations for general circuit design, and interfacing the DLX2416 to microprocessors. Refer to the spe- cific data sheet and other Infineon / OSRAM Appnotes for more details. Electrical & Mechanical Description The internal electronics in these Intelligent Displays eliminates all the traditional difficulties of using multi-digit light emitting displays (segment decoding, drivers, and multiplexing).
