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
