MSC1937-01 Datasheet | OKI Electric

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 ma. .. MSC1937-01 provides the interface with the microputer only by two signal lines: DATA and SCLK. FEATURES - Can display up to 16 digits with either 14 or 16 segments plus ma/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 Output current : Up to - 20 m A (Digit) - 10 m A (Segment) : Plastic DIP - 5 m A (Segment) : Plastic QFP Withstand voltage : 58V - Can also be used for LED. - Pin patible with 10937 manufactured by Rockwell. - Supply voltage : 5V ± 10% - Package options: 40-pin plastic DIP (DIP40-P-600-2.54) (Product name: MSC1937-01RS) 44-pin plastic QFP (QFP44-P-910-0.80-K) (Product name: MSC1937-01GS-K) 1/16 ..
