MIC10939/10942/10943

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.
