Overview

The LC75838W is 1/8 to 1/10 duty general-purpose LCD display driver used

for character and graphics display. This product operates under the control of a

microcontroller and can directly drive an LCD with up to 380 segments. It can

also control up to 3 general-purpose output ports.

SPQFP64 10x10 / SQFP64

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

 CCB is ON Semiconductor® ’s original format. All addresses are managed

by ON Semiconductor® for this format.

 CCB is a registered trademark of Semiconductor Components Industries, LLC.
