30-Bit Duplex Controller/Driver with Digital/Analog Dimming and Keyscan Functions
GENERAL DESCRIPTION
The MSC1200-01/1200V-01 is a Bi-CMOS display driver for 1/2-duty vacuum fluorescent
display tube. This device consists of a 64-bit shift register, latches, an analog dimming circuit,
a digital dimming circuit, a keyscan circuit, and drivers.
The interface with a microcomputer can be done only with four signal lines (CS, DATA I/O,
CLOCK, and INT). Also, the DATA I/O and CLOCK signal lines can be shared with other
peripherals by using the chip select function.
