Overview

The LC75878W 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 730 segments. It 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
