Dot Matrix Display Controller Summary Information*—Not Recommended for New Designs General Description The MIC10939, MIC10942, and MIC10943 Dot Matrix Display 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 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.
Features • • • • • • • • 20-character display driver cascadable to 80 characters Standard 5 × 12 character font Separate cursor driver output Two 128 × 23 PLAs provides segment decoding for full 96-character ASCII set, plus 32 special characters Serial or parallel data input for 8-bit display mode controls Brightness, refresh rate, and display mode controls 40-pin DIP or 44-pin PLCC (MIC10939) 28-pin DIP (MIC10942 and MIC10943) Ordering Information Part Number Temperature Range 0°C to +70°C 0°C to +70°C –40°C to +85°C 0°C to +70°C –40°C to +85°C 0°C to +70°C –40°C to +85°C Package 44-Pin PLCC 40-pin P-DIP 40-pin P-DIP 40-pin P-DIP 40-pin P-DIP 40-pin P-DIP 40-pin P-DIP MIC10939J-50 MIC10939P-50 MIC10939PE-50 MIC10942P-50 MIC10942PE-50 MIC10943P-50 MIC10943PE-50 Micrel has received the rights from Rockwell International to manufacture and market this product and reproduce the specifications, including references to Rockwell.
