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 generalpurpose 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 deco...
