LC75844M - 1/4 Duty General-Purpose LCD Driver

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 display.

Ordering number : ENN6235 CMOS IC LC75844M 1/4 Duty General-Purpose LCD Driver 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. Package Dimensions unit: mm 3204-MFP36S [LC75844M] 36 19 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.
