LC75832E

Static Drive, 1/2-Duty Drive General-Purpose LCD Driver

ON Semiconductor 

LC75832E, LC75832W

Static Drive, 1/2-Duty Drive

General-Purpose LCD Driver

Overview

The LC75832E and 75832W are static drive or 1/2-duty drive,

microcontroller-controlled general-purpose LCD drivers that can be used

in applications such as frequency display in products with electronic tuning.

In addition to being capable to drive up to 108 segments directly, they can

control up to 4 general-purpose output ports. Since the LC75832E and

LC75832W 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

 Serial data control of switching between static drive mode and 1/2 duty

drive mode.

 Up to 54 segments can be displayed in static drive (1/1 duty) mode and up

to 108 segments can be displayed in 1/2 duty drive mode.

 Serial data input supports CCB* format communication with the system

controller.

 Serial data control of the power-saving mode based backup function and the

all segments forced off function.

 Serial data control of switching between the segment output port and

general-purpose output port functions (up to 4 general-purpose output

ports).

 Serial data control of the frame frequency of the common and segment

output waveforms.

 Either RC oscillator operating or external clock operating mode can be

selected with the serial control data.

 High generality, since display data is displayed directly without the

intervention of a decoder circuit.

 Independent VLCD for the LCD driver block

(VLCD can be set to any voltage in the range of 2.7 to 6.0 volts.)

regardless of the logic block supply-voltage.

 The INH pin allows the display to be forced to the off state.

 Allows compatible operation with the LC75822 (822 mode transfer

function).
