MIC10941/10939

V. F. Alphanumeric and Bargraph Display Controller

Summary Information*—Not Recommended for New Designs

General Description

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).

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.

Features

• 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)
