LC75844M:1/4 Duty LCD Display Driver

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.

技术特性
  • Support for 1/4-duty 1/3-bias or 1/3-duty 1/3-bias drive techniques under serial data control.
  • Serial data input supports CCB format communication with the system controller. (Support 3.3V and 5V operation)
  • Serial data control of the power-saving mode based backup function and the all segments forced off function.
  • Serial data control of switching between the segment output port and general-purpose output port function. (Support for up to 4 general-purpose output ports)
  • Support for the PWM output function of a maximum of 3ch. (It can output from the general-purpose output port ).
  • Support for clock output function of 1ch.
  • Serial data control of the frame frequency of the common and segment output waveforms.
  • Serial data control of switching between the internal oscillator operating mode and external clock operating mode.
  • High generality, since display data is displayed directly without the intervention of a decoder circuit.
  • The INH pin allows the display to be forced to the off state.
  • Incorporation of an oscillator circuit. (Incorporation of resistor and capacitor for an oscillation)
