Dot Matrix Display Controller Summary Information*—Not Recommended for New Designs General Description The MIC10938 and MIC10939 Dot Matrix Display Controller is a two-chip MOS/LSI general purpose display controller system designed to interface to dot matrix displays (vacuum fluorescent or LED).
The two-chip set will drive displays with up to 35 anodes (dots) and up to 20 grids (characters) plus a cursor.
The chips can be cascaded to drive larger displays of as many as 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 × 7 character font Separate cursor driver output Direct drive capability for vacuum-fluorescent displays 128 × 35 PLA provides segment decoding for full 96character ASCII set, plus 32 special characters • Serial or parallel data input for 8-bit display and control characters • 40-pin DIP or 44-pin PLCC 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 0°C to +70°C –40°C to +85°C Package 44-pin PLCC 40-pin P-DIP 40-pin P-DIP 44-pin PLCC 40-pin P-DIP 40-pin P-DIP MIC10938J-50 MIC10938P-50 MIC10938PE-50 MIC10939J-50 MIC10939P-50 MIC10939PE-50 ‡ Micrel has received the rights from Rockwell International to manufacture and market this product and reproduce the specifications, including references to Rockwell.
