Overview

The LC75824E and LC75824W are 1/4 duty general purpose LCD display drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. In addition to being able to directly drive up to 204 LCD segments, the LC75824E and LC75824W can also control up to 12 general-purpose output ports.



Features

• Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive of up to 204 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 general-purpose output port functions

• Serial data control of the normal mode current drain

• High generality since display data is displayed directly without decoder intervention.

• The INH pin can force the display to the off state.

• RC oscillator circuit
