Overview

The LC75878E and LC75878W are 1/8 to 1/10 duty general-purpose LCD display drivers used for character and graphics display. These products operate under the control of a microcontroller and can directly drive an LCD with up to 730 segments. They can also control up to 4 general-purpose output ports.

Features

? 1/8duty–1/4bias, 1/9duty–1/4bias, and 1/10duty–1/4bias drive schemes can be controlled from serial data.

1/8duty–1/4bias: up to 600 segments

1/9duty–1/4bias: up to 666 segments

1/10duty–1/4bias: up to 730 segments

? 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.

? Direct display of display data without the use of a decoder provides high generality.

? Built-in display contrast adjustment circuit.

? Up to 4 general-purpose output ports are included.

? Independent LCD driver block power supply VLCD.

? The INH pin is provided. This pin turns off the display and forces the general-purpose output ports to the low level.

? RC oscillator circuit
