1/3 Duty General-Purpose

LCD Display Drivers

LC75833E, 75833W, 75833JE

Overview

The LC75833E, LC75833W, and LC75833JE are 1/3-duty

general-purpose LCD display drivers that can be used for

frequency display in electronic tuners under the control of

a microcontroller. The LC75833E and LC75833W can

drive an LCD with up to 105 segments directly, the

LC75833JE can drive an LCD with up to 93 segments

directly. The LC75833E and LC75833W and LC75833JE

can also control up to 8 general-purpose output ports.

Since the LC75833E, LC75833W, and LC75833JE use

separate power supply systems for the LCD drive block

and the logic block, the LCD driver block power-supply

voltage can be set to any voltage in the range 2.7 to 6.0

volts, regardless of the logic block power-supply voltage.

Features

• Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias

LCD drive under serial data control.

LC75833E, LC75833W:

up to 105 segments

LC75833JE:

up to 93 segments

(without the S12, S23, S24, S35 segment output pins

from the LC75833E, LC75833W)

• 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

• Serial data control of switching between the segment

output port and the general-purpose output port

functions

• High generality, since display data is displayed directly

without decoder intervention.

regardless of the logic block power-supply voltage.)

• The INH pin can force the display to the off state.

• RC oscillator circuit
