LC75843UGA
CMOS IC
1/1 to 1/4 Duty General-Purpose
LCD Display Driver
http://onsemi.com
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 3ch, 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 3.3V and 5V 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 3ch. ( It can output from the general-purpose output port ).
Support for clock output function of 1ch.( 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.
