LC75809PT
1/4 and 1/3-Duty General-Purpose
LCD Driver
Overview
The LC75809PT is the 1/4 duty and 1/3 duty general-purpose
microprocessor-controlled LCD driver that can be used in applications such
as frequency display in products with electronic tuning. In addition to being
able to drive up to 352 segments directly, the LC75809PT can also control up
to 12 general-purpose output ports. Because it has the PWM output of a
maximum of 6 ch, the brightness control of the LED backlight of RGB
2
can be done. Incorporation of an oscillation circuit helps to reduce the
number of external resistors and capacitors required.

Features
Support for 1/4-duty 1/3-bias or 1/3-duty 1/3-bias drive techniques under
serial data control.
When 1/4-duty : Capable of driving up to 352 segments
When 1/3-duty : Capable of driving up to 267 segments
Serial data input supports CCB* format communication with the system
controller. (Support 3.3 V and 5 V operation)
Serial data control of the power-saving mode based backup function and
the all segments forced off function.
Serial data control of switching between the segment output port and
general-purpose output port function.
(Support for up to 12 general-purpose output ports)
Support for the PWM output function of a maximum of 6 ch.
(It can output from the general-purpose output port).
Support for clock output function of 1 ch.
(It can output from the general-purpose output port).
Serial data control of the frame frequency of the common and segment
output waveforms.
Serial data control of switching between the internal oscillator operating
mode and external clock operating mode.
High generality, since display data is displayed directly without the
intervention of a decoder circuit.
Built-in display contrast adjustment circuit.
The INH pin allows the display to be forced to the off state.
Incorporation of an oscillator circuit.
(Incorporation of resistor and capacitor for an oscillation)
