ON LC75878WS-E Duty general-purpose lcd driver Datasheet

LC75878W
1/8 to 1/10-Duty General-Purpose
LCD Driver
Overview
The LC75878W is 1/8 to 1/10 duty general-purpose LCD display driver used
for character and graphics display. This product operates under the control of
a microcontroller and can directly drive an LCD with up to 730 segments. It
can also control up to 4 general-purpose output ports.
Features
 1/8duty–1/4bias, 1/9duty–1/4bias, and 1/10duty–1/4bias drive schemes can
be controlled from serial data.
1/8duty–1/4bias: up to 600 segments
1/9duty–1/4bias: up to 666 segments
1/10duty–1/4bias: up to 730 segments
 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.
 Direct display of display data without the use of a decoder provides high
generality.
 Built-in display contrast adjustment circuit.
 Up to 4 general-purpose output ports are included.
 Independent LCD driver block power supply VLCD.
 The INH pin is provided. This pin turns off the display and forces the
general-purpose output ports to the low level.
 RC oscillator circuit

Input that turns the display off and forces the general-purpose output ports low.
• When INH is low (VSS)
• Display off
S1 to S73 = “L” (VLCD4).
S74/COM10, S75/COM9 = “L” (VLCD4)
COM1 to COM8 = “L” (VLCD4).
• General-purpose output ports P1 to P4 = low (VSS)
• When INH is high (VDD)
• Display on
• The states of the general-purpose output ports can be set by
the PC1 to PC4 control data.
However, serial data can be transferred when the INH pin is low.
VLCD0
90
LCD drive 4/4 bias voltage (high level) supply pin. The level on this pin can be
changed by the display contrast adjustment circuit.
However, (VLCD0 - VLCD4) must be greater than or equal to 4.5 V.
Also, external power must not be applied to this pin since the pin circuit includes the
display contrast adjustment circuit.
VLCD1
91
LCD drive 3/4 bias voltage (middle level) supply pin. This pin can be used to supply
the 3/4 (VLCD0 - VLCD4) voltage level externally.
VLCD2
92
LCD drive 2/4 bias voltage (middle level) supply pin. This pin can be used to supply
the 2/4 (VLCD0 - VLCD4) voltage level externally.
VLCD3
93
LCD drive 1/4 bias voltage (middle level) supply pin. This pin can be used to supply
the 1/4 (VLCD0 - VLCD4) voltage level externally.
VLCD4
94
LCD drive 0/4 bias voltage (low level) supply pin. Fine adjustment of the display
contrast can be implemented by connecting an external variable resistor to this pin.
However, (VLCD0 - VLCD4) must be greater than or equal to 4.5 V, and VLCD4
must be in the range 0 V to 1.5 V, inclusive.

Control Data Functions
1. PC1 to PC4: General-purpose output port state setting data
These control data bits set the states of the general-purpose output ports P1 to P4.
Output pin

P3
P4
General-purpose output port state setting data
PC1

PC4
For example, if PC1 and PC2 are set to 1, and PC3 and PC4 are set to 0, then the output pins P1 and P2 will output
high levels (VDD) and the output pins P3 and P4 will output low levels (VSS).
2. CT0 to CT3, CTC: Display contrast setting data
These control data bits set the display contrast.

CTC: Display contrast adjustment circuit state setting
CTC
Display contrast adjustment circuit state
0
The display contrast adjustment circuit is disabled, and the VLCD0 pin level is forced to the VLCD level.
1
The display contrast adjustment circuit operates and the display contrast is adjusted.
Note that although the display contrast can be adjusted by operating the built-in display contrast adjustment circuit, it
is also possible to apply fine adjustments to the contrast by connecting an external variable resistor to the VLCD4 pin
and modifying the VLCD4 pin voltage. However, the following conditions must be met: (VLCD0 – VLCD4)  4.5 V,
and 1.5 V  VLCD4  0 V.
3. SC: Segment on/off control data
This control data bit controls the on/off state of the segments.
SC
Display state
0
On
1
Off
However, note that when the segments are turned off by setting SC to 1, the segments are turned off by outputting
segment off waveforms from the segment output pins.

4. BU: Normal mode/power saving mode control data
This control data bit controls the normal mode and power saving mode.
BU
Mode
0
Normal mode
Power-saving mode.
The common and segment pins go to the VLCD4 level and the oscillator on the OSC pin is stopped. Note that the
states of the general-purpose output ports P1 to P4 are set by PC1 to PC4 in the control data during power saving
1
mode as well as normal mode.

The INH Pin and Display Control
Since the IC internal data (the display data 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 to S73,
S74/COM10, S75/COM9, and COM1 to COM8 to the VLCD4 level and the P1 to P4 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 3, 4, and 5.)
Power Supply Sequence
The following sequences must be observed when power is turned on and off. (See figures 3, 4, and 5.)
• Power on: Logic block power supply (VDD) on  LCD driver block power supply (VLCD) on
• Power off: LCD driver block power supply (VLCD) off  Logic block power supply (VDD) off
However, if the logic and LCD driver blocks use a shared power supply, then the power supplies can be turned on and
off at the same time.

Notes on Transferring Display Data from the Controller
The display data is transferred to the LC75878W in five operations. All of the display data should be transferred within
30 ms to maintain the quality of the displayed image.
