LC75814V

1/4 Duty General-Purpose LCD Driver

Overview

The LC75814V is a 1/4 duty general-purpose LCD driver

that can be used for frequency display in electronic tuners

under the control of a microcontroller. The LC75814V can

drive an LCD with up to 64 segments directly. The

LC75814V can also control up to 4 general-purpose

output ports. Since the LC75814V uses 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

• Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive

of up to 64 segments under serial data control.

• 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.

• Independent VLCD for the LCD driver block (VLCD can

be set to any voltage in the range 2.7 to 6.0 volts,

regardless of the logic block power-supply voltage.)

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

• RC oscillator circuit
