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.

鈥?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.
鈥?Serial data input supports CCB format communication
with the system controller.
鈥?Serial data control of the power-saving mode based
backup function and all the segments forced off function
鈥?Serial data control of switching between the segment
output port and the general-purpose output port
functions
鈥?High generality, since display data is displayed directly
without decoder intervention.
