MSC1951-01 General Description

MSC1951-01 is a Bi-CMOS bargraph and alphanumeric display controller designed to interface with either vacuum fluorescent display.

MSC1951-01 can drive displays with up to 16 figures with either 16 segment bargraph or sevensegment type code plus a decimal point and comma tail.

MSC1951-01 adopts a serial interface system, which allows data transfer from the microcomputer only by two signal lines of SCLK and DATA.
