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.
