MSC1951-01
MSC1951-01 is 7-Segment x 16-Digit or 16-Segment x 6-Bargraph display Controller/Driver manufactured by OKI Electric.
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 ma tail.
..
MSC1951-01 adopts a serial interface system, which allows data transfer from the microputer only by two signal lines of SCLK and DATA.
FEATURES
- Can display up to 16 digits of 7-segment type character with ma/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.
- Driver output Current :
- 20 m A max. (Digit)
- 10 m A (Segment), Plastic DIP
- 05 m A (Segment), Plastic QFP Withstand voltage : 58 V max.
- Can be used for LED.
- Pin patible with 10951 manufactured by Rockwell.
- Power supply voltage : 5V ± 10%
