LC75805PE
1/1 to 1/4 Duty General-Purpose
LCD Driver with LED Driver
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 7 ch 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 5 V 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)

(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.

(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.

Note) If (PF0, PF1, PF2, PF3) = (X, 1, 0, 1), (X, X, 1, 1) are set, the frame frequency (fosc/1408, fCK/1408) of
setting (PF0, PF1, PF2, PF3) = (0, 1, 0, 0) is selected.

Display Control and the INH Pin
Since the LSI internal data (1/4 Duty Drive: LCD display data D1 to D140 + LED display data LT1 to LT48 + control
data, 1/3 Duty Drive: LCD display data D1 to D108 + LED display data LT1 to LT48 + control data, 1/2 Duty Drive:
LCD display data D1 to D74 + LED display data LT1 to LT48 + control data, Static Drive: LCD display data D1 to
D38 + LED display data LT1 to LT48 + control data) is undefined when power is first applied, applications should set
the INH pin low at the same time as power is applied to turn off the display of LCD and LED (LD1 to LD48 High
impedance, COM1 and COM2/S38 to COM4/S36 and S35 to S1 VSS level). The serial data is transferred from the
controller during this period, and then input INH =“H” after the serial data is transferred. This procedure prevents
meaningless display at power on.
