* Computer Control Bus (CCB) is an ON Semiconductor’s original bus format and
the bus addresses are controlled by ON Semiconductor.
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 V
LCD
for the LCD driver block (V
LCD
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.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed,
damage may occur and reliability may be affected.
Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended
Operating Ranges limits may affect device reliability.
