Overview

The LC75864E and LC75864W are 1/4 duty LCD display

drivers that can directly drive up to 96 segments and can

control up to four general-purpose output ports. These

products also incorporate a key scan circuit that accepts

input from up to 30 keys to reduce printed circuit board

wiring.

Features

• Key input function for up to 30 keys (A key scan is

performed only when a key is pressed.)

• 1/4 duty - 1/2 bias and 1/4 duty - 1/3 bias drive schemes

can be controlled from serial data (up to 96 segments).

• Sleep mode and all segments off functions that are

controlled from serial data

• Segment output port/general-purpose output port

function switching that is controlled from serial data

• Serial data I/O supports CCB format communication

with the system controller.

• Direct display of display data without the use of a

decoder provides high generality.

• Provision of an on-chip voltage-detection type reset

circuit prevents incorrect displays.

• RC oscillator circuit
