The MIC10951 will drive 16-segment bargraph or 7-segment plus comma and decimal numeric displays with up to 16 display positions. The controller accepts command and data input words on a clocked serial input line. Commands control the on/off duty cycle, starting character position, and number of characters to display. Encoded data words display bargraph position (single segment or increasing bar length), numbers, comma, decimal, and selected upper and lower case letters. No external drive circuitry is required for displays that operate on 20mA of drive current up to 50V. A 64 x 16-bit segment decoder provides character set decoding for the display. |
