LC75843UGA
1/1 to 1/4-Duty General-Purpose
LCD Driver
Overview
The LC75843UGA is the 1/1 to 1/4 duty general-purpose microprocessor-
controlled LCD driver that can be used in applications such as Automotive
display. In addition to being able to drive up to 100 segments directly, the
LC75843UGA 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 static(1/1duty) or 1/2-duty 1/2-bias or 1/3-duty 1/3-bias or 1/4-
duty 1/3-bias drive techniques under serial data control.
When 1/1-duty : Capable of driving up to 28 segments
When 1/2-duty : Capable of driving up to 54 segments
When 1/3-duty : Capable of driving up to 78 segments
When 1/4-duty : Capable of driving up to 100 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.
(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 LCD drive bias voltage stabilization 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)
AEC-Q100 qualified and PPAP capable.

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.
