LC75813E

1/3, 1/4-Duty General-Purpose LCD Driver

ON Semiconductor 

LC75813E, LC75813T

1/3, 1/4-Duty General-Purpose

LCD Driver

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.

 Independent VLCD for the LCD driver block (VLCD can be set to any

voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-

supply voltage.)

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

 RC oscillator circuit
