MSC1937-01
14/16-Segment ¥ 16-Digit Display Controller/Driver
This version:MNSCov1.913979-701
Previous version: Jul. 1996
GENERAL DESCRIPTION
MSC1937-01 is a Bi-CMOS alphanumeric display controller designed to interface with either
vacuum fluorescent display.
MSC1937-01 can drive displays with up to 16 digits with either 14 or 16 segments plus a decimal
point and comma.

MSC1937-01 provides the interface with the microcomputer only by two signal lines: DATA and
SCLK.
FEATURES
• Can display up to 16 digits with either 14 or 16 segments plus comma/point.
• 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.
• Built-in PLA (64 types of ASCII characters (capital letters only) can be displayed).
• Executable in 1-byte instruction format
• Drive capability
