FUNCTIONAL DESCRIPTION
The ML9060 is an LCD driver LSI with an internal shift register and a set of internal data latches
and is capable of driving LCD displays of up to 320 segments either in the static mode or in the
1/2 duty mode. The display data is read into the shift register serially from the DATA IN pin
at the rising edge of the CLOCK IN input signal. The display data is transferred internally to
the data latches at the High level of the LOAD IN input signal and is output to the segments
via the segment drivers in this IC. The display data in the shift register is output via the DATA
OUT pin in synchronization with the falling edge of the CLOCK IN input signal. The display
data should be input in the sequence of SEG160, SEG159, ... , SEG2, SEG1 for proper display of
data.
Description of Pin Functions
• M/S
This is the input pin for selecting either the Master mode or the Slave mode. This LSI goes into
the master mode when this pin is High and enters the Slave mode when this pin is Low.
• D/S
This input pin is for selecting either the dynamic display mode at 1/2 duty (D mode - “H” input)
or the static display mode (S mode - “L” input).
Note that the internal bias resistor is made ON in the dynamic (D) mode and is turned OFF in
the static mode (S).
• OSC I/E
This is the input pin for selecting whether to use the external clock input mode, or the internal
Rf oscillation mode or the external Rf oscillation mode.
When this pin is tied to the “H” level, the internal Rf oscillation mode or the external Rf
oscillation is used. When this pin is tied to the “L” level, the external clock input is used for the
operation of the LSI.
In the slave mode of operation of this LSI, any input to this pin will be ignored. Hence, tie this
pin to VDD or GND in the slave mode.
• OSC1, OSCR, OSC2
These are the pins for the oscillator for generating the common signal.
In the Master mode (M/S pin = “H”):
It is possible to select from among the three modes - internal Rf oscillation mode, external Rf
oscillation mode, and the external clock input mode. During the static display operation mode,
a common signal with 1/128th the frequency of the clock oscillator is output via the COM OUT
pin.
During the 1/2 duty dynamic display operation mode, a common signal with 1/64th the
frequency of the clock oscillator is output via the COM OUT pin.
• Internal Rf oscillation mode: Tie the OSC I/E pin to “H”, short the pins OSCR and OSC2, and
leave the pin OSC1 open.
• External Rf oscillation mode: Tie the OSC I/E pin to “L”, connect an external resistor Rf
between the pins OSC1 and OSC2, and leave the pin OSCR open.
• External clock input mode: Tie the OSC I/E pin to “L”, leave open the pins OSCR and OSC2,
and input the external clock signal to the pin OSC1.
8/17
ML9060¡ Semiconductor
In the Slave mode (M/S pin = “L”):
Leave open the pins OSCR and OSC2 and connect the pin OSC1 to the COM OUT pin of the
ML9060 which has been set in the master mode. The common signal that is input to the pin OSC1
will be used as the internal common signal and is also output via a buffer from the COM OUT
pin.
• COM OUT
This is the common signal output pin. Connect this pin to the OSC1 pin of the ML9060 that is
set in the slave mode.
During operation in the master mode (M/S pin = “H”) for static display, a common signal with
1/128th the frequency of the oscillator is output.
During operation in the master mode (M/S pin = “H”) for 1/2 duty dynamic display, a common
signal with 1/64th the frequency of the oscillator is output.
During operation in the slave mode (M/S pin = “L”), the common signal that is input at the pin
OSC1 is output from this pin via a buffer.
• SYNC
This is the I/O pin for common signal synchronization.
This pin becomes the synchronization signal output pin during operation in the master mode
(M/S pin = “H”) for 1/2 duty dynamic display.
This pin becomes the synchronization signal input pin during operation in the slave mode (M/
S pin = “H”) for 1/2 duty dynamic display.
For cascade operation in the 1/2 duty display mode, connect the SYNC pins of all ML9060 ICs
used together.
During operation in the static display mode, this pin is tied to the “L” level inside the IC.
Connect this pin either to GND or leave it open.
• DATA IN
This is the display data input pin. Input the display data in the sequence of SEG160, SEG159,
... , SEG2, SEG1. The segment is turned ON when the display data is “H” and OFF when “L”.
• DATA OUT
This is the display data output pin. During the static display mode of operation, the data of the
160th stage of the shift register is output from this pin. During the 1/2 duty dynamic display
mode, the data of the 320th stage of the shift register is output from this pin.
• CLOCK IN
This is the input pin for the shift clock of the display data. The display data that is input at the
DATA IN pin is input serially to the shift register at the rising edge of the CLOCK IN signal.
Also, the display data in the shift register is output from the DATA OUT pin at the falling edge
of the CLOCK IN signal.
• CLOCK OUT
This is the output pin for the shift clock of the display data. The shift clock signal that is input
to the CLOCK IN pin is output via a buffer from this pin.
• LOAD IN
This is the input pin for the display data load signal.
The display data in the shift register is output as such to the segment driver when this signal is
at the “H” level. When this signal is made “L”, the shift register is isolated from the segment
drivers, and the display data of the shift register just before this pin goes “L” is retained in the
data latches and transfered to the segment drivers.
9/17
ML9060¡ Semiconductor
• LOAD OUT
This is the output pin for the display data load signal. The load signal that is input to the LOAD
IN pin is output from this pin via a buffer.
• SEG-TEST IN
This is the input pin for making all segments ON. When this pin is “H”, all segment outputs
(SEG1 to SEG160) become ON irrespective of the display data and the Blank signal. When this
pin is made “L”, each of the segment outputs (SEG1 to SEG160) become ON or OFF according
to the display data.
• SEG-TEST OUT
This is the output pin for making all segments ON. The segment ON signal that is input to at
the SEG-TEST IN pin is output via a buffer.
• BLANK IN
This is the input pin for making all segments OFF. When this pin is “H”, all segment outputs
(SEG1 to SEG160) become OFF irrespective of the display data. When this pin is made “L”, each
of the segment outputs (SEG1 to SEG160) becomes ON or OFF according to the display data. The
BLANK IN is valid when the segment ON signal is "L".
• BLANK OUT
This is the output pin for making all segments OFF. The segment OFF signal that is input to the
BLANK IN pin is output via a buffer.
• SEG1 to SEG160
These are the signal outputs for driving the LCD segments and are connected to the corresponding
segment pins of the LCD panel.
During the Static mode of operation:
The SEGn output corresponds to bit n of the display data in the data latch A. The display data
in the data latch B becomes invalid. In the segment ON condition, a signal with a phase opposite
to that of the COM OUT signal is output from these pins. In the segment OFF condition, a signal
with a phase identical to that of the COM OUT signal is output from these pins.
During the 1/2 duty dynamic display mode of operation:
The SEGn output corresponds to bit n of the display data in the data latch A when COM A has
been selected and to bin n of the display data in the data latch B when COM B has been selected.
In the segment display ON condition, a signal opposite in phase to that of the selected COM
output is output from these pins. In the segment display OFF condition, a signal identical in
phase to that of the selected COM output is output from these pins.
• COM A, COM B
These are the outputs for LCD display and are connected to the common pins of the LCD panel.
During the Static mode of operation:
COM A and COM B both output a signal with the same phase as that of the COM OUT signal.
10/17
ML9060¡ Semiconductor
During the 1/2 duty dynamic display mode of operation:
COM A and COM B change their states at every cycle of the COM OUT signal and repeat the
selected and non-selected modes always opposing each other in phase. A signal with the same
phase as that of the COM OUT signal is output in the selected mode. A voltage equal to 1/2V
LCD
is output in the non-selected mode.
When COM A is in the selected mode (that is, COM B is in the non-selected mode), the segment
outputs (SEG1 to SEG160) output signals corresponding to the display data in the data latch A.
When COM B is in the selected mode (that is, COM A is in the non-selected mode), the segment
outputs (SEG1 to SEG160) output signals corresponding to the display data in the data latch B.
