General Description
The MIC10937 Alphanumeric Display Controllers is a MOS/
LSI general purpose display controllers designed to interface
to segmented displays (vacuum fluorescent or LED).
The MIC10937 will drive displays with up to 16 characters
with 14 or 16 segments. Segment decoding within each
device provides for the ASCII character set (upper case only).
No external driver circuitry is required for displays that oper-
ate on 20mA of drive current up to 50V. A 16 64-bit segment
decoder provides internal ASCII character set decoding for
the display.
Micrel has received the rights from Rockwell International to
manufacture and market this product and reproduce the
specifications, including references to Rockwell.
