MSC1209
42-Bit Vacuum Fluorescent Display Tube Driver with Digital Dimming Function
GENERAL DESCRIPTION
The MSC1209 is a Bi-CMOS display driver for a 1/2-duty vacuum fluorescent display tube. The
MSC1209 consists of an 84-bit shift register, an 84-bit latch circuit, a 10-bit digital dimming circuit,
42-bit segment drivers, a 2-bit grid circuit, and a cascade control circuit.
The MSC1209 is interfaced with a microcontroller by using three signal lines of LOAD, CLOCK,
and DATA. The cascaded MSC1209 ICs can share LOAD, CLOCK, and DATA.
FEATURES
• Power supply voltage: 8V to 18V (Built-in 5V regulator for logic)
• Operating temperature range: –40 to +105°C
• Driving 42 segments directly: V_OH=V_DD–0.5V at I_OH=–3.0mA (V_DD=15.0V)
• Built-in digital dimming circuit
10-bit resolution
Programmable in the duty range of 0/2048 (0%) to 1016.5/2048 (49.6%)
• 3 interfaces with microcontroller: LOAD, CLOCK, DATA
• Cascade connection available
(The cascaded MSC1209 ICs can share LOAD, CLOCK, and DATA.)
• Built-in oscillation circuit with an external capacitor (a single pin is used)
• Built-in power-on reset circuit
• Package:
56-pin plastic QFP (QFP56-P-910-0.65-2K) (Product name: MSC1209GS-2K)
