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.
