1 / 14 page Ordering number : ENN6235 92299TH (OT) No. 6235-1/14 Overview The LC75844M is a 1/4 duty general-purpose LCD driver that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75844M can drive an LCD with up to 88 segments directly. The LC75844M can also control up to 4 general-purpose output ports. Since the LC75844M uses separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage. Features • Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive of up to 88 segments under serial data control. • Serial data input supports CCB format communication with the system controller. • Serial data control of the power-saving mode based backup function and all the segments forced off function • Serial data control of switching between the segment output port and the general-purpose output port functions • High generality, since display data is displayed directly without decoder intervention. • Independent VLCD for the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage.) • The INH pin can force the display to the off state. • RC oscillator circuit Package Dimensions unit: mm 3204-MFP36S 0.15 15.3 1 18 36 19 0.85 0.35 0.8 SANYO: MFP36S [LC75844M] LC75844M SANYO Electric Co.,Ltd.
