MSC1951-01
7-Segment ¥ 16-Digit or 16-Segment ¥ 6-Bargraph display Controller/Driver
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 seven-
segment 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.
FEATURES
• Can display up to 16 digits of 7-segment type character with comma/point or of 16-segment
type bargraph.
• The number of display digits is programmable within 16.
• The brightness adjustment is programmable by 1/32 step.
• The display contents can be changed at any digit.
• Buit-in PLA can display alphanumeric characters, e.g., 0 to 9 A, C, E, F, P, L (capital letters), b,
and d (small letters). In addition, 16-segment dot display and bar display are allowed.
• Instruction is executed by one byte.
