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
Package Dimensions
 Support for 1/4 duty 1/2 bias or 1/4 duty 1/3 bias drive of up to 64
unit : mm (typ)
segments under serial data control.
 Serial data input supports CCB format communication with the
9.75
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.
