CMOS IC
LC75813E, 75813T
1/3, 1/4 Duty General-Purpose LCD Driver
Overview
The LC75813E and LC75813T are 1/3 duty and 1/4 duty
general-purpose LCD drivers that can be used for
frequency display in electronic tuners under the control of
a microcontroller. The LC75813E and LC75813T can
drive an LCD with up to 344 segments directly. The
LC75813E and LC75813T can also control up to 8
general-purpose output ports. Since the LC75813E and
LC75813T use 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
• Switching between 1/3 duty and 1/4 duty drive
techniques under serial data control.
• Switching between 1/2 bias and 1/3 bias drive
techniques under serial data control.
• Up to 261 segments for 1/3 duty drive and 344 segments
for 1/4 duty drive can be displayed.
• 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.
