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.
    <LC75890W(SQFP48)>
        When 1/4-duty drive : Capable of driving up to 148 segments
        When Static drive : Capable of driving up to 37 segments
    <LC75890E(QIP44M)>
        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.
    <LC75890W : Support for up to 12 general-purpose output ports>
    <LC75890E : Support for up to 11 general-purpose output ports>
• 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)
