7-Segment 16-Digit 16-Segment 6-Bargraph display Controller/Driver
GENERAL DESCRIPTION
MSC1951-01 Bi-CMOS bargraph alphanumeric display controller designed interface with either vacuum fluorescent display. MSC1951-01 drive displays with figures with either segment bargraph sevensegment type code plus decimal point comma tail. MSC1951-01 adopts serial interface system, which allows data transfer from microcomputer only signal lines SCLK DATA.
FEATURES
display digits 7-segment type character with comma/point 16-segment type bargraph. number display digits programmable within brightness adjustment programmable 1/32 step. display contents changed digit. Buit-in display alphanumeric characters, e.g., (capital letters), (small letters). addition, 16-segment display display allowed. Instruction executed byte. Driver output Current max. (Digit) (Segment), Plastic (Segment), Plastic Withstand voltage max. used LED. compatible with 10951 manufactured Rockwell. Power supply voltage Package options: 40-pin plastic (DIP40-P-600-2.54) (Product name MSC1951-01RS) 44-pin plastic (QFP44-P-910-0.80-K) (Product name MSC1951-01GS-K)
