10939, 10942, and 10943 Dot Matrix Display Controller
DESCRIPTION
The Rockwell 10939,10942, and 10943 Dot Matrix Display Controller is a three-<:hip MaS/LSI general purpose display controller system designed to interface to dot matrix displays (vacuumfluorescent 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 BO characters. 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.
