Overview

The LC75838E and LC75838W 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 380 segments. They can also control up to 3 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 320 segments

1/9duty–1/4bias: up to 351 segments

1/10duty–1/4bias: up to 380 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 3 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
