LC75890W

LC75890E

Overview

The LC75890W and LC75890E are 1/4 duty and static drive general-purpose LCD display drivers that can be used

for displaying segments for household appliances, home audio visual products, portable devices and other such

products under the control of a microcontroller.The LC75890W can drive up to 148 segments directly, and the

LC75890E can drive up to 132 segments directly. In addition the LC75890W can control up to 12 general-purpose

output ports, and the LC75890E can control up to 11 general-purpose output ports. They can control the brightness of

the LED backlight of RGB, because they have the PWM output of greatest 3CH built-in. Incorporation of the

oscillation circuit helps to reduce the number of external resistors and capacitors required. Incorporation of the LCD

drive bias voltage stabilization circuit helps to reduce the capacitors for the LCD drive bias voltage stabilization.

Features

• Support for 1/4-duty 1/3-bias or static drive techniques under serial data control.

<LC75890W(SQFP48)>
