Compatible, LED Display Decoder Driver
Description
The ICM7243 is an 8-character, alphanumeric display driver
and controller which provides all the circuitry required to
interface a microprocessor or digital system to a 14-segment
or 16-segment display. It is primarily intended for use in
microprocessor systems, where it minimizes hardware and
software overhead. Incorporated on-chip are a 64-character
ASClI decoder, 8 x 6 memory, high power character and
segment drivers, and the multiplex scan circuitry.
6-bit ASCll data to be displayed is written into the memory
directly from the microprocessor data bus. Data location
depends
upon
(MODE = 1) or Random access mode (MODE = 0). In the
Sequential Access mode the first entry is stored in the
lowest location and displayed in the “left-most” character
position. Each subsequent entry is automatically stored in
the next higher location and displayed to the immediate
“right” of the previous entry. A DISPlay FULL signal is pro-
vided after 8 entries; this signal can be used for cascading
devices together. A CLeaR pin is provided to clear the mem-
ory and reset the location counter. The Random Access

mode allows the processor to select the memory address

and display digit for each input word.
F40.6
The character multiplex scan runs whenever data is not
being entered. It scans the memory and CHARacter drivers,
E40.6
and ensures that the decoding from memory to display is
done in the proper sequence. Intercharacter blanking is
F40.6
provided to avoid display ghosting.
