com ¡ Semiconductor MSC1200-01/1200V-01 ¡ Semiconductor 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.
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) 1/26 FEDL1200V-03 ¡ Semiconductor MSC1200-01/1200V-01 www.
