111-Bit 2/3-Duty Controller/Driver With Digital Dimming Function

The MSC1230 is a Bi-CMOS Display driver with digital dimming function. It enables switching between 1/3-duty vacuum fluorescent (VF) Display tube and universal VF Display tube by pin control. The MSC1230 consists of a 112-bit Shift register a 111-bit latch, a 10-bit digital dimming circuit, 37 segment drivers, and 3 grid drivers. The MSC1230 provides an Interface with a microcomputer only by three signal lines: *CS, DATA-IN, and Clock By using the chip select function, the DATA-IN and Clock signal lines CAN be shared by other peripheral circuits.
