LC75805PE
CMOS IC
1/1 to 1/4 Duty General-Purpose
LCD Display Driver with LED Driver
http://onsemi.com
Overview
LC75805PE is the 1/1 to 1/4 duty general-purpose LCD display driver with the LED driver to use for the instrument
panel display by control with the controller. In addition, LC75805PE is able to drive up to 48 LED and LCD of up to
140 segments directly, and has a built-in 7ch PWM function for brightness adjustment of LED. Furthermore, because
of built-in the oscillator circuit, it is possible to reduce external resister and capacitor for oscillation.
Features
Switch of Static Drive, 1/2 Duty Drive, 1/3 Duty Drive and 1/4 Duty Drive can be controlled by serial data.
Static Drive (1/1 Duty Drive) : Capable of driving up to 38 segments.
1/2 Duty Drive
: Capable of driving up to 74 segments.
1/3 Duty Drive
: Capable of driving up to 108 segments.
1/4 Duty Drive
: Capable of driving up to 140 segments.
Frame frequency of common and segment output waveform can be controlled by serial data.
Turning on/off LED can be controlled by serial data. (Capable of driving up to 48 LED)
Built-in 7ch PWM function for brightness adjustment of LED. (Resolution of 128 steps)
Frame frequency of LED driver output waveform can be controlled by serial data.
Serial data input supports CCB format communication with the system controller. (Support 5V operation)
Backup function and forced turning off all segments by power-saving mode can be controlled by serial data.
Switch of the internal oscillator operating mode and the external clock operating mode can be controlled by serial
data.
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.
Built-in Oscillator circuit (Built-in resister and capacitor for oscillation)
CCB is ON Semiconductor® ’s original format. All addresses are managed
by ON Semiconductor® for this format.

(Note 1) The input of serial data is taken in at the rising edge of CL, and latched at the falling edge of CE. In addition,
this IC has the function that counts the number of CL clock to receive the correct serial data. That is to say,
because it isn’t latched at the falling edge of CE when the number of the count of CL in each serial data is
wrong, receiving wrong serial data can be prevented.
