LC75897PWS-T 1/3 and 1/4-Duty General-Purpose LCD Driver

LC75897PWS-T
CMOS LSI
1/3 and 1/4-Duty
General-Purpose LCD Driver
www.onsemi.com
Overview
The LC75897PWS-T is 1/3 duty and 1/4 duty general-purpose LCD
display driver that can be used for frequency display in electronic tuners
under the control of a microcontroller. The LC75897PWS-T can drive
an LCD with up to 512 segments directly. The LC75897PWS-T can
also control up to 8 general-purpose output ports. The LC75897PWS-T
has a built-in of up to three PWM output port channels, which enables
to adjust the brightness of the RGB LED backlight.
SPQFP144 20x20 / SQFP144
Features
 Switching between 1/3 duty and 1/4 duty drive techniques under serial data control.
 Switching between 1/2 bias and 1/3 bias drive techniques under serial data control.
 Up to 387 segments for 1/3 duty drive and 512 segments for 1/4 duty drive can be displayed.
 Switching between the segment, general-purpose, PWM, and clock output ports can be controlled using serial data
(up to 8 general-purpose output ports, up to 3-channel PWM output ports, and one clock output port).
 Serial data input supports CCB format communication with the system controller.
 Serial data control of the power-saving mode based backup function and all the segments forced off function.
 Serial data control of the frame frequency for common and segment output waveforms.
 Serial data control of switching between the RC oscillator operating mode and external clock operating mode.
 High generality, since display data is displayed directly without decoder intervention.
 Built-in display contrast adjustment circuit
 Independent VLCD for the LCD driver block
 The INH pin can force the display to the off state.
 RC oscillator circuit

CCB is ON Semiconductor® ’s original format. All addresses are managed

Note: PCn = 1: The output pin Pn is set high (VLCD) (n = 1 to 8).
PCn = 0: The output pin Pn is set low (VSS) (n = 1 to 8).
For example, if output pins S4/P4 and S5/P5 are selected as general-purpose output ports, setting PC4 to 1 and PC5 to 0
causes the output pin P4 to be set high (VLCD) and P5 to be set low (VSS).

Note that although the contrast of the display can be adjusted by running the internal display contrast adjustment
circuit, it is also possible to adjust it by changing the voltage level on the LCD driver block power supply VLCD pin.
However, VLCD0 must always be greater than or equal to 2.7V.

However, note that the segments are turned off by setting SC to 1, the segments are turned off by outputing segment off
waveforms from the segment output pins.

The LC75897PWS-T stops the oscillation at the OSC pin if it is set up for the RC oscillator operating mode (OC = 0) and
1
stops receiving the external clock if it is set up for the external clock operating mode (OC = 1). The IC also sets the common
and segment output pins to the VSS level. The output pins S1/P1 to S8/P8, however, remain available as general-purpose
output ports as configured by control data bits PS10, PS11, PS20, PS21, PS30, PS31, PS40, PS41, and PS5 to PS8 (not
available as PWM output or clock output ports).

LC75897PWS-T
The INH pin and Display Control
Since the IC internal data (1/3 duty: the display data D1 to D387 and the control data, 1/4 duty: the display data D1
to D512 and the 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 (This sets the S1/P1 to S8/P8, S9 to S128, COM1 to COM3,
and COM4/S129 to the VSS level.) and during this period send serial data from the controller. The controller should
then set the INH pin high after the data transfer has completed. This procedure prevents meaningless displays at
power on. (See Figures 5 and 6.)
Notes on the Power On/Off Sequences
Applications should observe the following sequences when turning the LC75897PWS-T power on and off.
(See Figures 5 and 6)
 At power on: Logic block power supply (VDD) on  LCD driver block power supply (VLCD) on
 At power off: LCD driver block power supply (VLCD) off  Logic block power supply (VDD) off
However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and
off at the same time.

LC75897PWS-T
Notes on Controller Transfer of Display Data
Since the LC75897PWS-T accepts the display data (D1 to D387) divided into three separate transfer operations
when using 1/3 duty drive scheme and the data (D1 to D512) divided into four separate transfer operations when
using 1/4 duty drive scheme, we recommend that applications transfer all of the display data within a period of less
than 30ms to prevent observable degradation of display quality.
OSC pin peripheral circuits
(1) RC oscillator operating mode (control data OC = 0)
When RC oscillator operating mode is selected, an external resistor Rosc and an external capacitor Cosc must be
connected between the OSC pin and GND.
OSC

Cosc
(2) External clock operating mode (control data OC = 1)
When selecting the external clock operating mode, connect a current protection resistor Rg (2.2 to 22k) between
the OSC pin and the external clock output pin (external oscillator). Determine the value of the resistance according
to the maximum allowable current value of the external clock output pin. Also make sure that the waveform of the
external clock is not excessively distorted.
