描述 Description

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.FEATURES
? Power supply voltage : 8V to 18V (built-in 5V regulator for logic)
? Operating temperature range : –40°C to +85°C
? 30-segment driver outputs (IOH = –6mA at VOH = VDD – 0.8V)
? Built-in analog dimming circuit (PWM: 12.5% Max at 6-bit resolution)
? Built-in digital dimming circuit (11-bit resolution)
? Built-in 5 x 6 keyscan circuit
? Built-in RC oscillation circuit (external R and C)
? Built-in power-on-reset circuit.
? The product name differs depending on the bonding option pin selected:
?? PWM OUT/BLANK IN : MSC1200-01
?? DATA OUT : MSC1200V-01
? Package :
???56-pin plastic QFP (QFP56–P–910-0.65–2K)
?? ??? (Product name: MSC1200-01GS-2K/MSC1200V-01GS-2K)
