LC75897PW

Overview

The LC75897PW is 1/3 duty and 1/4 duty general-purpose LCD display

driver that can be used for frequency display in electronic tuners under the

control of a microcontroller. The LC75897PW can drive an LCD with up to

512 segments directly. The LC75897PW can also control up to 8 general-

purpose output ports. The LC75897PW has a built-in of up to three PWM

output port channels, which enables to adjust the brightness of the RGB LED

backlight.

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 387 segments for 1/3 duty drive and 512 segments for 1/4 duty drive can be displayed.

 Switching between the segment, general-purpose, PWM, and clock output ports can be controlled using serial data

(up to 8 general-purpose output ports, up to 3-channel PWM output ports, and one clock output port).

 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 the frame frequency for common and segment output waveforms.

 Serial data control of switching between the RC oscillator operating mode and external clock operating mode.

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

 Built-in display contrast adjustment circuit

 Independent VLCD for the LCD driver block

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

 RC oscillator circuit
