MSC1200-01/1200V-01
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 : â40°C to +85°C
⢠30-segment driver outputs (IOH = â6mA at VOH = VDD â 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 (QFP56âPâ910-0.65â2K) (Product name: MSC1200-01GS-2K/MSC1200V-01GS-2K)
