LC75813E,

LC75813T

Overview

The LC75813E and LC75813T are 1/3 duty and 1/4 duty general-purpose LCD drivers that can be used for

frequency display in electronic tuners under the control of a microcontroller. The LC75813E and LC75813T can

drive an LCD with up to 344 segments directly. The LC75813E and LC75813T can also control up to 8 general-

purpose output ports. Since the LC75813E and LC75813T use 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

 Switching between 1/3 duty and 1/4 duty drive techniques under serial data control.

 Switching between 1/2 bias and 1/3 bias drive techniques under serial data control.

 Up to 261 segments for 1/3 duty drive and 344 segments for 1/4 duty drive can be displayed.

 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.

 Serial data control of frame frequency for common and segment output waveforms.

 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
