80-DOT COMMON/SEGMENT DRIVER
GENERAL DESCRIPTION
The MSM5260 is a dot matrix common/segment LCD driver LSI which is fabricated using low
power CMOS metal gate technology. This LSI consists of 80-bit shift register, 80-bit latch, 80-bit
level shifter and 80-bit 4-level driver.
It converts display data, which is serially received from an LCD controller LSI, to parallel data,
and outputs LCD driving waveform to LCD.
This LSI can drive a variety of LCD panels since the bias voltage can be optionally supplied from
an external source.

FUNCTIONAL DESCRIPTION
Pin Functional Description
• DI1
The data input pin for the 80-bit shift register (between 1st to 80th bit). The display data is
clocked in to this pin. (Positive logic)
• CP
Clock pulse input pin for 80-bit shift register. The data is shifted to the 80-bit shift register at
the falling edge of the clock pulse. A data setup time (tSETUP) and a data hold time (tHOLD)
are required between a DI1 signal and a clock pulse.
Clock pulse rise time (tr) and clock pulse fall time (tf) should be a maximum of 50ns
respectively.
• DO80
The 80th bit output from the 80-bit shift register.
The data which is input from DI1 is clocked out with the delay in the number of the bits of the
shift register.
When extending the number of characters, this pin is used to connect to the next MSM5260
in cascade.
• LOAD
The signal for latching the shift register contents is input from this pin.
When LOAD pin is set at "H" level, the shift register contents are transferred to the 80-bit 4level driver through the 80-bit level shifter.
When LOAD pin is set at "L" level, the last display output data (O1 to O80), which was
transferred when LOAD pin was at "H" level, is held.
• DF
Synchronous signal input pin for alternate signal for LCD driving.
8/12
¡ Semiconductor
MSM5260
• COM/SEG
Selection signal input pin. MSM5260 is used either as common driver or segment driver
according to input signal level at COM/SEG pin.
When this pin is set when at "H" level, MSM5260 is used as a common driver, while it is used
as a segment driver when at "L" level.
The display driving data O1 to O80 are determined according to the combination of latched
data and DF signal, as shown in Table 1 below.

Remarks
Common driver
Segment driver
When MSM5260 is used as a common driver, both LOAD pin and COM/SEG pin are to be
connected to VDD. In this case, a bias voltage of common side’s non-select level is to be
supplied to V2 and V3 pins.
• VDD, VSS
Supply voltage pins. VDD should be 4.5 to 5.5V.
VSS is a ground pin (VSS = 0V)
• V2, V3, V5
Bias supply voltage pins to drive the LCD. Use an external bias voltage supply for driving
the LCD.
• O1 to O80
Display data output pins which correspond to each bit of the 80-bit latch.
One of VDD, V2, V3 and V5 is selected as a display driving voltage source according to the
combination of latched data level and DF signal.
NOTES ON USE
Note the following when turning power on and off :
The LCD drivers of this IC requiers a high voltage. For this reason, if a high voltage is applied
to the LCD drivers with the logic power supply floating, excess current flows. This may damage
the IC. Be sure to carry out the following power-on and power-off sequences :
When turning power on :
First VDD ON, next V5, V3, V2 ON. Or both ON at the same time.
When turning power off :
First V5, V3, V2 OFF, next VDD OFF. Or both OFF at the same time.
