V. F. Alphanumeric and Bargraph Display Controller
Summary Information*—Not Recommended for New Designs
General Description
Features
The MIC10941 and MIC10939 Alphanumeric and Bargraph
Display Controller is a two-chip MOS/LSI general purpose
display controller system designed to interface with bargraph
and segmented displays (vacuum fluorescent or LED).
• 20-character display driver cascadable to 80 characters
• Direct drive capability for vacuum-fluorescent displays
• 128 × 18 PLA provides segment decoding for ASCII
characters (all caps only) and bargraph patterns
• Serial or parallel data input for 8-bit display and control
characters
• Brightness, refresh rate, and display mode controls
• Separate cursor driver output
• 40-pin DIP or 44-pin PLCC (MIC10939)
• 24-pin DIP package (MIC10941)
The two-chip set will drive displays with up to 16 segments
(plus decimal point and comma tail) and up to 20 grids
(characters) plus a cursor. The chips can be cascaded to
drive larger displays of 80 characters. Segment decoding for
ASCII characters and bargraph patterns is accomplished
through an internal PLA.
