An Intelligent Display also provides internal memory for the
four digits. This approach allows the user to asynchronously
address one of four digits, and load new data without regard to
the LED multiplex timing.
Figure 1 is a block diagram of the DLX3416. The unit consists
of four (5x7) LED arrays and a single CMOS integrated chip.
The IC chip contains the column 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 users of the DLX3416 (referred to as 3416
hereafter) alphanumeric Intelligent Displays. This appnote also
covers device electrical description and operation, consider-
ations for general circuit design, and interfacing the 3416 to
microprocessors. Refer to the specific 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).
