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.

Features

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

When 1/4-duty drive : Capable of driving up to 148 segments

When Static drive : Capable of driving up to 37 segments

When 1/4-duty drive : Capable of driving up to 132 segments

When Static drive : Capable of driving up to 33 segments

? Support for display segment on, off, or blinking for each segment output pin under serial data control.

? Serial data control of the power-saving mode based backup function and the all segments forced off function.

? Serial data control of switching between the segment output port and general-purpose output port function.

? Support for the PWM output function of a maximum of 3ch. (It can output from the general-purpose output port ).

? Serial data control of the frame frequency of the common and segment output waveforms.

? Serial data control of the segment blinking frequency.

? Serial data control of switching between the internal oscillator operating mode and external clock operating mode.

? Serial data input supports CCB format communication with the system controller.

? Independent VLCD for the LCD driver block.

? Built-in LCD drive bias voltage stabilization circuit.

? The INH pin allows the display to be forced to the off state.

? Incorporation of an oscillator circuit. (Incorporation of resistor and capacitor for an oscillation)
