* Computer Control Bus (CCB) is an ON Semiconductor’s original bus format and
the bus addresses are controlled by ON Semiconductor.
LC75839PW
1/4 and 1/3-Duty General-Purpose
LCD Driver
Overview
The LC75839PW is 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 208 segments directly, the LC75839PW can also control up to 4
general-purpose output ports. Because it has the PWM output of a maximum
of 3 ch, the brightness control of the LED backlight of RGB 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 208 segments
When 1/3-duty: Capable of driving up to 159 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 4 general-purpose output ports)
Support for the PWM output function of a maximum of 3-ch.
(It can output from the general-purpose output port)
Support for clock output function of 1-ch.
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.
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)

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.
