Overview
The MSC1201-xx is a 1/2 duty vacuum fluorescent display tube driver implemented in Bi-CMOS technology. This LSI consists of 64-bit shift registers, 64 latches, PWM conversion circuit, a digital dimming circuit, 30-segment driver and 2-grid driver. As the MSC1201-xx has both a digital dimming circuit and a PWM conversion circuit which converts PWM signal for lamp dimming control to PWM signal for VFD tube dimming control, the dimming control can be realized without any external circuit.
FEATURES
• Single supply voltage : VDD = 8 V to 18 V (built-in 5 V logic regurator)
• Operating temperature range : Ta = –40°C to +85°C
• 30-segment driver outputs (IOH = –6 mA at VOH = VDD
– 0.8 V)
• 2-grid pre-driver outputs (IOH = –30 mA at VOH = VDD
– 0.8 V)
• Built-in digital dimming circuit (11-bit resolution)
• Built-in oscillation circuit (external R and C, fOSC = 2.0 MHz)
• Built-in Power-On-Reset circuit.
• Lamp PWM signal -> Buil-in PWM conversion circuit for vacuum fluorescent display tube.
• Built-in RC Oscillation (external R and C)
• Correspondence between shift register and output segment is settable optionally using built in mask programmable 30 x 30 PLA.
• Package : 44-pin plastic QFP (QFP44–P–910-0.80–2K)(Product name: MSC1201-xxGS-2K) xx indicates the code number
