V. F. Dot Matrix Display Controller
Summary Information*—Not Recommended for New Designs
General Description
The MIC10939, MIC10942, and MIC10943 Dot Matrix Dis-
play Controller is a three-chip MOS/LSI general purpose
display controller system designed to interface to dot matrix
displays (vacuum fluorescent or LED).
The three-chip set will drive displays with up to 46 anodes
(dots) and up to 20 grids (characters) plus a cursor. The chips
can be cascaded to drive larger displays of up to 80 charac-
ters.
An internal PLA-type decoder provides character decoding
and dot pattern generation for the full 96-character ASCII set
and an additional 32 special characters.
Micrel has received the rights from Rockwell International to
manufacture and market this product and reproduce the
specifications, including references to Rockwell.
