General Description
The MIC10941 and MIC10939 Alphanumeric and Bargraph
Display Controller is a two-chip MOS/LSI general purpose
display controller system designed to interface with bargraph
and segmented displays (vacuum fluorescent or LED).
The two-chip set will drive displays with up to 16 segments
(plus decimal point and comma tail) and up to 20 grids
(characters) plus a cursor. The chips can be cascaded to
drive larger displays of 80 characters. Segment decoding for
ASCII characters and bargraph patterns is accomplished
through an internal PLA.
Micrel has received the rights from Rockwell International to
manufacture and market this product and reproduce the
specifications, including references to Rockwell.
