V. F. Alphanumeric Display Controller
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.
Features
16-character display with decimal point and comma tail
14 or 16-segment drivers
Up to 66kHz data rate
Direct digit drive and 20mA at 50V
Supports vacuum fluorescent or LED displays
