9. PIN DESCRIPTION
VDD_ROW, +V1, VC, -V1 (Power Pin)
VDD_ROW is a power pin to supply power to the logic system. The voltage range is 2.7V to 5.5V with respect to the -V1 pin.
+V1, VC and -V1 are power supply pins to the LCD system. Their relationship is +V1
VC
VDD_ROW
-V1.
YD (Input Pin)
This input pin is used as a signal to start a frame and to reset the column address for writing. (Refer to Note 1)
LP (Input Pin)
This is an input pin and is used as a display data latch clock. The display data is latched at the falling edge of LP. (Refer to
Note 1)
FR (Input Pin)
This is an input pin and is used to change the LCD driving waveform polarity. If a power chip SSD1730 is used, the output FR
from the power chip should be connected to the FR pin of the row driver. (Refer to Note 1)
F1, F2 (Input Pin)
These are input pins and are used as driver pattern select signals. These two signals are generated by a column driver. If a
display system is formed by the column driver SSD1870 and the row driver SSD1881, outputs F10 and F20 from the column
driver should be connected to F1 and F2 of the row driver respectively. (Refer to Note 1)
DOFF# (Input Pin)
This is an input pin and is used to control the LC display. When it is set at "L" level, all common outputs are forced to V
C
level
and the LC display will be forced to blank, however, the contents of the latches are maintained. In the normal display operation,
it is set to "H" level. (Refer to Note 1)
SEL (Input Pin)
SSD1881 can be configured as 140 common outputs or 160 common outputs which is controlled by this input pin SEL.
When SEL is set at "L" level, 160 outputs are chosen and COM0 to COM159 will be used. When SEL is set at "H" level, 140
outputs are chosen and COM8 to COM147 will be used.
CIO1, CIO2 (I/O Pin)
These are I/O pins and they can be configured as an input or an output depending on the signal of SHL. When SHL is set at "L"
level, CIO1 is input and CIO2 is output. When SHL is set at "H" level, CIO1 is output and CIO2 is input. The output transition
occurs on the falling edge of LP. (Refer to Note 1)

SHL (Input Pin)
This is an input pin and is used to select the output shift direction and to configure CIO1 and CIO2. Below table
shows the relationship between SEL, SHL, CIO1, CIO2 and the output shift direction.

LSEL (Input Pin)
This is an input pin and is used to select 1P Normal Operation or 1/2P Operation. That can cope with different
LCD having different response time.
When LSEL is set at "L" level, 1P Normal Operation is selected. when LSEL is set at "H" level, 1/2P Operation is
selected.
CSEL (Input Pin)
This is a chip select signal input. When only one common driver is used, CSEL should be set at "L" level. When
multiple common drivers are used, CSEL of the leading chip must be tied to "L" level and that of other chips must
be tied to "H" level.
TEST1 (Input Pin)
This is a reserved pin and it must be set at "L" level in the normal operation.
TEST2 (Input Pin, only exists on gold-bumped die)
This is a reserved pin and it must be set at "L" level in the normal operation.
COM0-COM159 (Output Pin)
These are output pins and provide common driving signals to the LCD panel. Output transition occurs at the falling
edge of LP.
NCx and DUMCORx (Dummy Pin)
These are NC pins and dummy pins. They must be left open & unconnected. Don't group the NC pins or dummy
pins together.






Note 1: If an MLA LCD system is formed by SSD1881 row driver, SSD1870 column driver and SSD1730 power chip, 1nF capacitors are
necessary for the capacitor coupling purpose. Refer to the Application example for circuit connection.

10. FUNCTIONAL BLOCK DESCRIPTIONS
Controller and Data Register
Based on the input signal of FR, F1, F2 and LP, this Controller will generate signals to control the Data Register.
Then, the Data Register will latch the data to the Common Cell Level Shifter according to the signals from the
Controller and the data from the Shift Register. The data is latched to the Common Cell Level Shifter at the falling
edge of LP.
Bi-directional Shift Register
This Shift Register will shift the input signals YD and CIO input according to the setting of SHL, SEL, LSEL and
CSEL. When SHL is set at "L" level, CIO1 is input and CIO2 is output. When SHL is set at "H" level, CIO1 is
output and CIO2 is input. The output transition occurs on the falling edge of LP.
Common Cell Level Shifter
This is a level interface circuit which is used to convert the signal voltage level from a logic system level to the LCD
driver system voltage level. When DOFF# is at "L" level, all common output voltage will be at VC level. When
DOFF# is at "H" level, the common output voltage will be changed according to the status of input signals of FR,
F1 and F2.
Table 7 shows the relationship among the common output voltage and the input signals FR, F1 and F2. Table 8
shows the relationship between line number and Common.

VCVDD_ROW-V1. All voltages are referenced to -V1 = 0V.
This device contains circuitry to protect the inputs against damage due to high static voltages of electric fields;
however, it is advised that normal precautions to be taken to avoid application of any voltage higher than maximum
rated voltages to this high impedance circuit. All dummy pins and NC pins must be left open & unconnected.
Don't group the NC pins together. The device may be light sensitive. Caution should be taken to avoid exposure
of this device to any light source during normal operation. This device is not radiation protected.

14. PRECAUTION

When SSD1881 is used with SSD1870 column driver and SSD1730 power chip to form a low power display
system, the power supply of SSD1881 is actually coming from the SSD1730 outputs. Proper power up and power
down sequence must be followed to protect and to ensure proper functioning of the system.

The recommended power up and down sequence is as follow:

Power up:
Pull DOFF# to L
Provide power to the SSD1730 MLA power chip and SSD1870 MLA column driver.
Provide LP pulses chain with other controller signals while keeping DOFF# at "L".
Wait for a minimum of 150ms to allow the SSD1730 MLA power chip building up appropriate power levels of
the display system.
