MIC10937

MIC10937/10957 Micrel MIC10937 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 operate 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 64 × 16-bit PLA provides segment decoding for ASCII character set (all caps only) Serial data input for 8-bit display and control data words 40-pin DIP or 44-pin PLCC Ordering Information Part Number MIC10937J-40 MIC10937P-40/ MIC10937P-50† MIC10937PE-40/ MIC10937PE-50† † Micrel has received the rights from Rockwell International to manufacture and market this product and reproduce the specifications, including references to Rockwell.
