LC75814V - 1/4 Duty General-Purpose LCD Driver

Key Features

  • Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive of up to 64 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.

Ordering number : EN6792 LC75814V CMOS LSI 1/4 Duty General-Purpose LCD Driver http://onsemi.com Overview The LC75814V 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 LC75814V can drive an LCD with up to 64 segments directly. The LC75814V can also control up to 4 generalpurpose output ports. Since the LC75814V 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 64 segments under serial data control.
