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 V
DD
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.
