1 General
Description
SSD0852 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix graphic
display system. It consists of 257 high voltage driving output pins for driving 128 Segments, 128
Commons and an ICON line.
SSD0852 displays data directly from its internal 128x129x2 bits Graphic Display Data RAM
(GDDRAM). Data/Commands are sent through I
2
C interface.
SSD0852 embeds a DC-DC Converter, an LCD Voltage Regulator, an On-Chip Bias Divider and an
On-Chip Oscillator, which reduce the number of external components. With the special design on
minimizing power consumption and die/package layout, SSD0852 is suitable for any portable battery-
driven applications requiring a long operation period and compact size.

7 FUNCTIONAL BLOCK DESCRIPTIONS
7.1 I
2
C communication Interface
The IIC communication interface consists of slave address bit (SA0), I
2
C-bus data signal (SDA)
and I
2
C-bus clock signal (SCL). Both the SDA and the SCL must be connected to pull-up resistors.
There are also an input signal
RES
which is used for the initialization of device.
a) Slave address bit (SA0)
SSD0852 has to recognize the slave address before transmitting or receiving any information by
the I
2
C-bus. The device will responds to the slave address following by the slave address bit
("SA0" bit) and the read/write select bit ("R/W" bit) with the following byte format,
b

b
6
b
5
b
4
b
3
b
2
b
1
b
0
0 1 1 1 1 0 SA0 R/W
"SA0" bit provides an extension bit for the slave address. Either "0111100" or "0111101" can be
selected as the slave address of SSD0852.
"R/W" bit determines the I
2
C-bus interface is operating at either write mode or read status mode.
b) I
2
C-bus data signal (SDA)
SDA acts as a communication channel between the transmitter and the receiver. The data and
the acknowledgement are sent through the SDA.
It should be noticed that the ITO track resistance and the pulled-up resistance at "SDA" pin
becomes a voltage potential divider. As a result, the acknowledgement would not be possible to
attain a valid logic 0 level in "SDA".
c) I
2
C-bus clock signal (SCL)
The transmission of information in the I
2
C-bus is following a clock signal, SCL. Each transmission
of data bit is taken place during a single clock period of SCL.
7.2 Command
Decoder
Input is directed to the command decoder based on the input of control byte which consists of a
D/C bit and a R/W bit. For further information about the control byte, please refer to the section
"I
2
C-bus Write data and read register status" on page 22. If both the D/C bit and the R/W bit are
low, the input signal is interpreted as a Command. It will be decoded and written to the
corresponding command register. If the D/C bit is high and the R/W bit is low, input signal is written
to Graphic Display Data RAM (GDDRAM).
7.3 Oscillator
Circuit
This module is an On-Chip low power oscillator circuitry with external resistor. The oscillator
generates the clock for the DC-DC voltage converter. This clock is also used in the Display Timing
Generator block

7.4 LCD Driving voltage Generator and Regulator
This module generates the LCD voltage needed for display output. It takes a single supply input
and generates necessary bias voltages. It consists of:
1. 3X, 4X, 5X and 6X DC-DC voltage converter
Please refer to Figure 4.
Figure 4 - DC-DC Converter Configurations
2. Voltage Regulator
The feedback gain control for LCD driving contrast curves can be selected by INTRS pin to either
internal (INTRS pin = H) or external (INTRS pin = L). If internal resistor network is enabled, eight
settings can be selected through software command. If external control is selected, external
resistors are required to be connected between V
SS
and V
R
(R
1
), and between V
R
and V
L6
(R

7.5 Graphic Display Data RAM (GDDRAM)
The GDDRAM is a bit mapped static RAM holding the bit pattern to be displayed. The size of the
RAM is 128 x 129 x 2 = 33024bits. Figure 6 is a description of the GDDRAM address map.
For mechanical flexibility, re-mapping on both Segment and Common outputs are provided.
For vertical scrolling of display, an internal register storing the display start line can be set to control
the portion of the RAM data mapped to the display. Figure 6 shows the case in which the display
start line register is set at 70H.
For those GDDRAM out of the display common range, they could still be accessed, for either
preparation of vertical scrolling data or even for the system usage.
7.6 Reset
Circuit
This block includes Power On Reset circuitry and the hardware reset pin,
RES
. Both of these have
the same reset function. Once
RES
receives a negative reset pulse, all internal circuitry will start to
initialize. Minimum pulse width for completing the reset sequence is 10us. Status of the chip after

7.7 Display Data Latch
This block is a series of latches carrying the display signal information. These latches hold the
data, which will be fed to HV Buffer Cell and Level Selector to output the required voltage level.
The number of latches is 128+129= 257
7.8 HV Buffer Cell (Level Shifter)
HV Buffer Cell works as a level shifter which translates the low voltage output signal to the required
driving voltage. The output is shifted out with an internal FRM clock which comes from the Display
Timing Generator. The voltage levels are given by the level selector which is synchronized with the
internal M signal.
7.9 Level
Selector
Level Selector is a control of the display synchronization. Display voltage can be separated into
two sets and used with different cycles. Synchronization is important since it selects the required
LCD voltage level to the HV Buffer Cell, which in turn outputs the COM or SEG LCD waveform.
7.10 LCD Panel Driving Waveform
The following is an example of how the Common and Segment drivers may be connected to a LCD
panel. The waveforms are shown in Figure 7 illustrating the desired multiplex scheme with N-line
Inversion feature is disabled (default).

The second command sets the n-line inversion register
from 3 to 33 lines to reduce display crosstalk. Register
values from 00001b to 11111b are mapped to 3 lines to
33 lines respectively. Value 00000b disables the N-line
inversion, which is the POR value.
To avoid a fix polarity at some lines, it should be noted
that the total number of mux (including the icon line)
should NOT be a multiple of the lines of inversion (n).

C-bus Write data and read register status
The I

C-bus interface gives access to write data and command into the device. Please refer to Figure 8
for the write mode of I
2
C-bus in chronological order.
Figure 8 - I
2
C-bus data format
Write mode
1) The master device initiates the data communication by a start condition. The definition of the start
condition is shown in Figure 9. The start condition is established by pulling the SDA from high to
low while the SCL stays high.
2) The slave address is following the start condition for recognition use. For the SSD0852, the slave
address is either "b0111100" or "b0111101" by changing the SA0 to high or low.
3) The write mode is established by setting the R/W bit to logic "0".
4) An acknowledgement signal will be generated after receiving one byte of data, including the slave
address and the R/W bit. Please refer to the Figure 10 for the graphical representation of the
acknowledge signal. The acknowledge bit is defined as that the SDA line is pulled down during
the high period of the acknowledgement related clock pulse.
5) After the transmission of the slave address, either the control byte or the data byte may be sent
across the SDA. A control byte mainly consists of Co and D/C bits following by six "0" `s.
a. If the Co bit is set as logic "0", the transmission of the following information will contain
data bytes only.

b. The D/C bit determines the next data byte is acted as a command or a data. If the D/C bit
is set to logic "0", it defines the following data byte as a command. If the D/C bit is set to
logic "1", it defines the following data byte as a data which will be stored at the GDDRAM.
The GDDRAM column address pointer will be increased by one automatically after each
data write.
6) Acknowledge bit will be generated after receiving each control byte or data byte.
7) The write mode will be finished when a stop condition is applied. The stop condition is also
defined in Figure 9. The stop condition is established by pulling the "SDA in" from low to high
while the "SCL" stays high.
Figure 9 - Definition of the start and stop condition
Figure 10 - Definition of the acknowledgement condition
Please be noted that the transmission of the data bit has some limitations.
1. The data bit, which is transmitted during each SCL pulse, must be kept at a stable state within
the "high" period of the clock pulse. Please refer to the Figure 11 for graphical representations.
Except in start or stop conditions, the data line can be switched only when the SCL is low.
2. Both the data line (SDA) and the clock line (SCL) should be pulled up by external resistors.

column address will be incremented by each data access after it is pre-set by the MCU and
returning to 0 once overflow (>127).
9.2 Set Upper Column Address
This command specifies the higher nibble of the 7-bit column address of the display data RAM.
The column address will be incremented by each set of data (LSB & MSB) access after it is pre-set
by the MCU and returning to 0 once overflow (>127).
9.3 Set Internal Regulator Resistor Ratio
This command is to enable any one of the eight internal resistor (IRS) settings for different
regulator gains when using internal regulator resistor network (INTRS pin pulled high). The
Contrast Control Voltage Range curves are given in the Figure 5.
9.4 Set Power Control Register
This command turns on/off the various power circuits associated with the chip.
9.5 Set Display Start Line
This command is to set Display Start Line register and to determine starting address of display
RAM. When starting address equals to 0, D
0
of Page 0 is mapped to COM0. When it equals to 1,
D
1
of Page0 is mapped to COM0. The display start line values of 0 to 127 are assigned to Page 0
to 15.
9.6 Set Display Offset
The second command specifies the mapping of display start line (COM0 if display start line register
equals to 0) to one of ROW0-127. This command has no effect on ICONS. COM0 is mapped to
ROW0 after reset.
9.7 Set Multiplex Ratio
This command switches default 128 multiplex mode to any multiplex from 16 to 128, if Icon is
disabled (POR). When Icon is set enable, the corresponding multiplex ratio setting will be mapped
to 17 to 129. The chip pads ROW0-ROW127 will be switched to corresponding COM signal output.
9.8 Set N-line Inversion
Number of line inversion is set by this command for reducing cross-talk noise. 3 to 33-line inversion
operations could be selected. At POR, this operation is disabled. It should be noted that the total
number of mux (including the icon line) should NOT be a multiple of the inversion number (N). Or
else, some lines will not change their polarity during frame change.
9.9 Set LCD Bias
This command is used to select a suitable bias ratio (1/5 to 1/12) required for driving the particular
LCD panel in use. The POR default 1/12 bias.

is set with 64 steps (6-bit) contrast control register. It is
a compound commands.
9.12 Set Gray Scale Mode (White/Light Gray/Dark Gray/Black)
Command 88(hex) to 8F(hex) are used to specify the four gray levels' pulse width at the four
possible frames. The four gray levels are called white, light gray, dark gray and black. Each level is
defined by 4 registers for 4 consecutive frames. For example, WA is a 4-bit register to define the
pulse width of the 1
st
frame in White mode. WB is a register for 2

9.13 Set PWM and FRC
This command is used to select the number of frames used in frame rate control, and the number
of levels in the pulse width modulation.
9.14 Set Segment Re-map
This command changes the mapping between the display data column address and segment
driver. It allows flexibility in layout during LCD module assembly. Please refer to Figure 6.
9.15 Set Icon Enable
This command enable/disable the Icon display. When Icon display is enabled and page address is
set to Page 16. This is only one way to set the page address to 16. Therefore, when writing data
for icons, ICON control register ON instruction would be used to set the page address to 16.
9.16 Set Entire Display On/Off
This command forces the entire display, including the icon row, to be "ON" regardless of the
contents of the display data RAM. This command has priority over normal/invert display. To
execute this command, Set Display On command must be sent in advance.
9.17 Set Normal/Inverse Display
This command sets the display to be either normal/invert. In normal display, a RAM data of 1
indicates an "ON" pixel. While in invert display, a RAM data of 0 indicates an "ON" pixel. The icon
line is not affected by this command.
9.18 Set Power Save Mode
To force the chip to enter Sleep Mode.
9.19 Start Internal Oscillator
After POR, the internal oscillator is OFF. It should be turned ON by sending this command to the
chip.
9.20 Set Display On/Off
This command turns the display on/off, by the value of the LSB.
9.21 Set Page Address
This command positions the page address to 0 to 15 possible positions in GDDRAM. Please refer
to Figure 6. The Page Address will be incremented automatically after writing the LSB of column
127 and returning to 0 once overflow (page address > 15).
Set Page Address command cannot be used to set the page address to "16". Use ICON control
register ON/OFF command to set the page address to "16".
9.22 Set COM Output Scan Direction
This command sets the scan direction of the COM output allowing layout flexibility in LCD module
assembly.
9.23 Set Modify-Read
This command stops the automatic increment of the column address after read display data. The
column address is still automatic increment due to write display data.
9.24 Exit Power-save Mode
This command releases the chip from either Standby or Sleep Mode and return to normal
operation.

This command specifies the frame frequency so as to minimize the flickering due to the ac main
frequency. The frequency is set to 90Hz(typical) at 128 mux after enabled internal oscillator
resistor.
9.33 OTP setting and programming
OTP (One Time Programming) is a method to adjust V
L6
. In order to eliminate the variations of
LCD module in term of contrast level, OTP can be used to achieve the best contrast of every
LCD modules.
OTP setting and programming should include two major steps of (1) Find the OTP offset and
(2) OTP programming as following,
Step 1. Find OTP offset
(1) Hardware Reset (sending an active low reset pulse to
RES
pin)
(2) Send original initialization routines
(3) Set and display any test patterns
(4) Adjust the contrast value (0x81, 0x00~0x3F) until there is the best visual contrast
(5) OTP setting steps = Contrast value of the best visual contrast - Contrast value of original
initialization
Example 1:
Contrast value of original initialization = 0x20
Contrast value of the best original initialization = 0x24
OTP offset value = 0x24 - 0x20 = +4
OTP setting command should be (0x82, 0x04)
Example 2:
Contrast value of original initialization = 0x20
Contrast value of the best original initialization = 0x1B
OTP setting = 0x1B - 0x20 = -5
OTP setting command should be (0x82, 0x0B)
Step 2. OTP programming
(6) Hardware Reset (sending an active low reset pulse to
RES
pin)
(7) Enable Oscillator (0xAB)
(8) Connect an external V
L6
(see diagram below)
(9) Send OTP setting commands that we find in step 1 (0x82, 0x10~0x1F)
(10) Send OTP programming command (0x83)
(11) Wait at least 2 seconds
(12) Hardware Reset
Verify the result by repeating step 1. (2) (3)
