General Description
SSD1805 is a single-chip CMOS LCD driver with controller for dot-matrix graphic liquid crystal display system.
SSD1805 consists of 200 high-voltage driving output pins for driving maximum 132 Segments, 68 Commons /
132 Segments, 64 Commons and 1 icon-driving Common / 132 Segments, 54 Commons and 1 icon-driving
Common / 132 Segments, 32 Commons and 1 icon-driving Common. SSD1805 can also be switched among
32, 54, 64 or 68 display multiplex ratios by hardware pin selection.
SSD1805 consists of 132 x 68 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from
common MCU through 8-bit 6800-series / 8080-series compatible Parallel Interface or 4-wires Serial
Peripheral Interface by software program selections.
SSD1805 embeds DC-DC Converter, On-Chip Oscillator and Bias Divider to reduce the number of external
components. With the advance design, low power consumption, stable LCD operating voltage and flexible die
package layout, SSD1805 is suitable for any portable battery-driven applications requiring long operation
period with compact size.

PIN DESCRIPTION
MSTAT
This pin is the static indicator driving output. The frame signal output pin, M, should be used as the back
plane signal for the static indicator. The duration of overlapping could be programmable. See Extended
Command Table for details.
6.2
M
This pin is the frame signal input/output. In master mode, the pin supplies frame signal to slave devices while
in slave mode, the pin receives frame signal from the master device.
6.3
CL
This pin is the display clock input/output. In master mode with internal oscillator enabled (CLS pin pulled
high), this pin supplies display clock signal to slave devices. In slave mode or when internal oscillator is
disabled, the pin receives display clock signal from the master device or external clock source.
6.4
/DOF
This pin is display blanking control between master and slave devices. In master mode, this pin supplies
on/off signal to slave devices. In slave mode, this pin receives on/off signal from the master device.
6.5
CS 1, CS2
These pins are the chip select inputs. The chip is enabled for MCU communication only when both CS 1 is
pulled low and CS2 is pulled high.
6.6
RES
This pin is the reset signal input. Initialization of the chip is started once this pin is pulled low. Minimum pulse
width for reset sequence is 20us.
6.7
D/ C
This pin is Data/Command control pin. When the pin is pulled high, the data at D7 - D0 is treated as display
data. When the pin is pulled low, the data at D7 - D0 will be transferred to the command register.
6.8
R/ W ( WR )
This pin is MCU interface input. When 6800 interface mode is selected, this pin will be used as Read/Write
(R/W ) selection input. Read mode will be carried out when this pin is pulled high and write mode when low.
When 8080 interface mode is selected, this pin is the Write ( WR ) control signal input. Data write operation is
initiated when this pin is pulled low and the chip is selected. When serial interface mode is selected, this pin
must be pulled low.
6.9
E( RD )
This pin is MCU interface input. When 6800 interface mode is selected, this pin will be used as the Enable (E)
signal. Read/write operation is initiated when this pin is pulled high and the chip is selected. When 8080
interface mode is selected, this pin is the Read ( RD ) control signal input. Data read operation is initiated
when this pin is pulled low and the chip is selected. When serial interface mode is selected, this pin must be
pulled high.
6.10 D7 - D0
These pins are the 8-bit bi-directional data bus in parallel interface mode. D7 is the MSB while D0 is the LSB.
When serial mode is selected, D7 is the serial data input (SDA) and D6 is the serial clock input (SCK).

6.11 VDDIO
This pin is the system power supply pin of bus IO buffer. Please refer to figure 19 on page 48 for connection
example.
6.12 VDD
This pin is the system power supply pin of the logic block.
6.13 VCI
Reference voltage input for internal DC-DC converter. The voltage of generated VOUT equals to the multiple
factor (2X, 3X, 4X or 5X) times VCI with respect to VSS1.
Note: Voltage at this input pin must be larger than or equal to VDD.
6.14 VSS
The VSS is the ground reference of the system.
6.15 VSS1
Reference voltage input for internal DC-DC converter. The voltage of generated VOUT equals to the multiple
factor (2X, 3X, 4X or 5X) times VCI with respect to VSS1.
Note: Voltage at this input pin must be equal to VSS.
6.16 VLREF
This pin is the ground of internal operation amplifier. In normal power mode, it must connect to VSS. In low
power mode, it must connect to VCI. Please refer to figure 19 on page 48 for the detail.
6.17 VHREF
This pin is the power supply pin of the internal operation amplifier. It must connect to VOUT.
6.18 VOUT
This is the most positive voltage supply pin of the chip. It can be supplied externally or generated by the
internal DC-DC converter. If the internal DC-DC converter generates the voltage level at VOUT, the voltage
level is used for internal referencing only. The voltage level at VOUT pin is not used for driving external
circuitry.
6.19 VFS
This is an input pin to provide an external voltage reference for the internal voltage regulator. The function of
this pin is only enabled for the External Input chip models which are required special ordering. For normal
chip model, please leave this pin NC (No connection).
6.20 VF
This pin is the input of the built-in voltage regulator for generating VOUT. When external resistor network is
selected (IRS pulled low) to generate the LCD driving level, VOUT, two external resistors, R1 and R2, should be
connected between VSS and VF, and VF and VOUT, respectively (see application circuit diagrams).

FUNCTIONAL BLOCK DESCRIPTIONS
7.1
Microprocessor Interface Logic
The Microprocessor Interface unit consists of three functional blocks for driving the 6800-series parallel
interface, 8080-series parallel interface and 4-wires serial peripheral interface. The selection of different
interfaces is done by P/ S pin and C68/ 80 pin. Please refer to the pin descriptions on page 8.
a) MPU 6800-series Parallel Interface
The parallel interface consists of 8 bi-directional data pins (D7-D0), R/ W ( WR ), D/ C , E( RD ),
CS 1 and CS2. R/ W ( WR ) input high indicates a read operation from the Graphic Display Data
RAM (GDDRAM) or the status register. R/ W ( WR ) input Low indicates a write operation to
Display Data RAM or Internal Command Registers depending on the status of D/ C input. The
E( RD ) input serves as data latch signal (clock) when high provided that CS 1 and CS2 are low
and high respectively. Please refer to Figure 11 & 12 on page 40 & 41 for Parallel Interface
Timing Diagram of 6800-series microprocessors. In order to match the operating frequency of the
GDDRAM with that of the MCU, some pipeline processing is internally performed which requires
the insertion of a dummy read before the first actual display data read. This is shown in Figure 3.

b) MPU 8080-series Parallel Interface
The parallel interface consists of 8 bi-directional data pins (D7-D0), E( RD ), R/ W ( WR ), D/ C ,
CS 1 and CS2. E( RD ) input serves as data read latch signal (clock) when low provided that CS 1
and CS2 are low and high respectively. Whether reading the display data from GDDRAM or
reading the status from status register is controlled by D/ C . R/ W ( WR ) input serves as data write
latch signal (clock) when low provided that CS 1 and CS2 are low and high respectively. Whether
writing the display data to the GDDRAM or writing the command to the command register is
controlled by D/ C . A dummy read is also required before the first actual display data read for
8080-series interface. Please refer to figure 13 & 14 on page 42 & 43 for Parallel Interface Timing
Diagram of 8080-series microprocessors.
c) MPU 4-wires Serial Interface
The 4-wires serial interface consists of serial clock SCK (D6), serial data SDA (D7), D/ C , CS 1
and CS2. SDA is shifted into a 8-bit shift register on every rising edge of SCK in the order of data
bit 7, data bit 6, …, data bit 0. D/ C is sampled on every eighth clock to determine whether the
data byte in the shift register is written to the Display Data RAM or command register at the same
clock. Please refer to figure 15 & 16 on page 43 & 44 for serial interface timing.
Remarks: For SPI mode, it is necessary to add one time of software reset command (code: E2) in
the first line of the initialization code.

Command Decoder and Command Interface
This module determines whether the input data is interpreted as data or command. Data is directed to this
module based upon the input of the D/ C pin. If D/ C pin is high, data is written to Graphic Display Data RAM
(GDDRAM). If D/ C pin is low, the input at D0 – D7 is interpreted as a Command and it will be decoded. The
decoded command will be written to the corresponding command register.
7.4
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 132
x 68 = 8,976bits. Table 5 on page 18 is a description of the GDDRAM address map in which the display start
line register is set at 18H. 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. 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.
Please be noticed that the display offset cannot be greater than the default mux mode for any circumstance.

LCD Driving Voltage Generator and Regulator
This module generates the LCD voltage required for display driving output. It takes a single supply input and
generates necessary bias voltage. It consists of:
1) 2X, 3X, 4X and 5X regulated DC-DC voltage converter
The built-in DC-DC regulated voltage converter is used to generate the large positive voltage supply.
SSD1805 can produce 2X, 3X, 4X or 5X boosting from the potential different between VSS1 - VCI. No
external boosting capacitors are required for configuration. Please refer to the command table for detail
description. The feedback gain control for LCD driving contrast curves can be selected by IRS pin to
either internal (IRS pin = H) or external (IRS 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 connect between Vss and VF (R1), and between VF and VOUT (R2). See application circuit diagrams for
detail connections.

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 the HV Buffer Cell and Level Selector to output the required voltage level. The numbers of latches of
different members are given by:
32 Mux mode: 132 + 33 = 165
54 Mux mode: 132 + 55 = 187
64 Mux mode: 132 + 65 = 197
68 Mux mode: 132 + 68 = 200
7.8
HV Buffer Cell (Level Shifter)
This block is embedded in the Segment/Common Driver Circuits. 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 that is synchronized with the internal M signal.
7.9
Level Selector
This block is embedded in the Segment/Common Driver Circuits. Level Selector is a control of the display
synchronization. Display voltage levels 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.

COMMAND DESCRIPTIONS
9.1
Data Read / Write
To read data from the GDDRAM, input High to R/W ( WR ) pin and D/ C pin for 6800-series parallel mode,
input Low to E( RD ) pin and High to D/ C pin for 8080-series parallel mode. No data read is provided in serial
interface mode. In normal data read mode, GDDRAM column address pointer will be increased by one
automatically after each data read. However, no automatic increase will be performed in read-modify-write
mode. Also, a dummy read is required before first valid data is read. See Figure 3 on page 15 in Functional
Block Descriptions section for detail waveform diagram. To write data to the GDDRAM, input Low to
R/W ( WR ) pin and High to D/ C pin for both 6800-series and 8080-series parallel mode. For serial interface
mode, it is always in write mode. GDDRAM column address pointer will be increased by one automatically
after each data write. It should be noted that, after the automatic column address increment, the pointer will
NOT wrap round to 0. The pointer will exit the memory address space after accessing the last column.
Therefore, the pointer should be re-initialized when progress to another page address.

Set Lower Column Address
This command specifies the lower nibble of the 8-bit column address of the display data RAM. The column
address will be increased by each data access after it is pre-set by the MCU.
9.3
Set Higher Column Address
This command specifies the higher nibble of the 8-bit column address of the display data RAM. The column
address will be increased by each data access after it is pre-set by the MCU.
9.4
Set Internal Gain Resistors Ratio
This command is to enable any one of the eight internal resistor sets for different gains when using internal
resistor network (IRS pin pulled high). In other words, this command is used to select which contrast curve
from the eight possible selections. Please refer to Functional Block Descriptions section for detail calculation
of the LCD driving voltage.
9.5
Set Power Control Register
This command turns on/off the various power circuits associated with the chip. There are two related power
sub-circuits could be turned on/off by this command. Internal voltage booster is used to generate the positive
voltage supply (VOUT) from the voltage input (VCI - VSS1). An external positive power supply is required if this
option is turned off. Output op-amp buffer is the internal divider for dividing the different voltage levels from
the internal voltage booster, VOUT. External voltage sources should be fed into this driver if this circuit is turned
off.
9.6
Set Display Start Line
This command is to set Display Start Line register to determine starting address of display RAM to be
displayed by selecting a value from 0 to 67. With value equals to 0, D0 of Page 0 is mapped to COM0. With
value equals to 1, D1 of Page0 is mapped to COM0 and so on. Display start line values of 0 to 67 are
assigned to Page 0 to 8. Please refer to Table 5 on Page 17 as an example for display start line set to 24
(18h).

Set Boost level
The internal DC-DC converter factor is set by this command. For SSD1805, 2X to 5X multiplying factors could
be selected. The default POR internal DC-DC converter setting can be selected by hardware pin, B0 & B1.
9.8
Set Contrast Control Register
This command adjusts the contrast of the LCD panel by changing the LCD driving voltage, VOUT, provided by
the On-Chip power circuits. VOUT is set with 64 steps (6-bit) in the contrast control register by a set of
compound commands. See Figure 8 for the contrast control flow.

Set Segment Re-map
This command changes the mapping between the display data column addresses and segment drivers. It
allows flexibility in mechanical layout of LCD glass design. Please refer to Table 5 on Page 15 for example.
9.10 Set LCD Bias
This command is used to select a suitable bias ratio required for driving the particular LCD panel in use. The
selectable values of this command for 68/64 MUX are 1/9 or 1/7, 54/32 MUX are 1/8 or 1/6. For other bias
ratio settings, extended commands should be used.
9.11 Set Entire Display On/Off
This command forces the entire display, including the icon row, to be illuminated regardless of the contents of
the GDDRAM. In addition, this command has higher priority than the normal/reverse display. This command
is used together with “Set Display ON/OFF” command to form a compound command for entering power save
mode. See “Set Power Save Mode” later in this section.
9.12 Set Normal/Reverse Display
This command turns the display to be either normal or reverse. In normal display, a RAM data of 1 indicates
an illumination on the corresponding pixel. While in reverse display, a RAM data of 0 will turn on the pixel. It
should be noted that the icon line will not affect, that is not reverse by this command.
9.13 Set Display On/Off
This command is used to turn the display on or off. When display off is issued with entire display is on, power
save mode will be entered. See “Set Power Save Mode” later in this section for details.
9.14 Set Page Address
This command enters the page address from 0 to 8 to the RAM page register for read/write operations.
Please refer to Table 5 on Page 17 for detail mapping.
9.15 Set COM Output Scan Direction
This command sets the scan direction of the COM output allowing layout flexibility in LCD module assembly.
See Table 5 on Page 17 for the relationship between turning on or off of this feature. In addition, the display
will have immediate effect once this command is issued. That is, if this command is sent during normal
display, the graphic display will have vertical flipping effect.

9.16 Set Read-Modify-Write Mode
This command puts the chip in read-modify-write mode in which:
1. Column address is saved before entering the mode
2. Column address is increased only after display data write but not after display data read.
This Read-Modify-Write mode is used to save the MCU’s loading when a very portion of display area is being
updated frequently. As reading the data will not change the column address, it could be get back from the
chip and do some operation in the MCU. Then the updated data could be written back to the GDDRAM with
automatic address increment. After updating the area, “Set End of Read-Modify-Write Mode” is sent to restore
the column address and ready for next update sequence.
9.17 Software Reset
Issuing this command causes some of the chip’s internal status registers to be initialized:
Read-Modify-Write mode is off
Static indicator is turned OFF
Display start line register is cleared to 0
Column address counter is cleared to 0
Page address is cleared to 0
Normal scan direction of the COM outputs
Internal gain resistors Ratio is set to 4
Contrast control register is set to 20h
9.18 Set End of Read-Modify-Write Mode
This command relieves the chip from read-modify-write mode. The column address before entering readmodify-write mode will be restored no matter how much modification during the read-modify-write mode.
9.19 Set Indicator On/Off
This command turns on or off the static indicator driven by the M and MSTAT pins.
When the “Set Indicator On” command is sent, the second command byte “Indicator Display Mode” must be
followed. However, the “Set Indicator Off” command is a single byte command and no second byte command
is required.
The status of static indicator also controls whether standby mode or sleep mode will be entered, after issuing
the power save compound command. See “Set Power Save Mode” later in this section.
9.20 NOP
A command causing the chip takes No Operation.
9.21 Set Test Mode
This command forces the driver chip into its test mode for internal testing of the chip. Under normal operation,
users should NOT use this command.
9.22 Set Power Save Mode
Entering Standby or Sleep Mode should be done by using a compound command composed of “Set Display
ON/OFF” and “Set Entire Display ON/OFF” commands. When “Set Entire Display ON” is issued when display
is OFF, either Standby Mode or Sleep Mode will be entered. The status of the Static Indicator will determine
which power save mode is entered. If static indicator is off, the Sleep Mode will be entered:
Internal oscillator and LCD power supply circuits are stopped
Segment and Common drivers output VSS level
The display data and operation mode before sleep are held
Internal display RAM can still be accessed
If the static indicator is on, the chip enters Standby Mode that is similar to sleep mode except addition with:
Internal oscillator is on
Static drive system is on
Please also be noted that during Standby Mode, if the software reset command is issued, Sleep Mode will be
entered. Both power save modes can be exited by the issue of a new software command or by pulling Low at
hardware pin RES .

EXTENDED COMMANDS
These commands are used, in addition to basic commands, to trigger the enhanced features designed for the
chip.
9.23 OTP setting and programming
OTP (One Time Programming) is a method to adjust VOUT. 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. Find the OTP offset and OTP programming as following,
Step 1. Find OTP offset
Hardware Reset (sending an active low reset pulse to RES pin)
Send original initialization routines
Set and display any test patterns
Adjust the contrast value 0x81, 0x00~0x3Funtil there is the best visual contrast
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 = -6
OTP setting command should be (0x82, 0x0A)
Step 2. OTP programming
Hardware Reset (sending an active low reset pulse to RES pin)
Connect an external VOUT (see diagram below)
Send OTP setting commands that we find in step 1 (0x82, 0x00~0X0F)
Send OTP programming command (0x83)
Wait at least 2 seconds
Hardware Reset
Verify the result by repeating step 1. (2) – (3)

0X06 \\ 0000 X3X2X1X0 , where X3X2X1X0 is the OTP offset value
0X83 \\ Send the OTP programming command.
Wait at least 2 seconds for programming wait time.
Verify the result:
After OTP programming, procedure 2 to 5 are repeated for inspection of the contrast on the panel.
9.24 Set Multiplex Ratio
This command switches default multiplex ratio to any multiplex mode from 2 to the maximum multiplex ratio
(POR value), including the icon line.
Max. MUX ratio: 68 for 68 MUX mode
65 for 64 MUX mode including icon line
55 for 54 MUX mode including icon line
33 for 32 MUX mode including icon line
The chip pins ROW0 - ROW67 will be switched to corresponding COM signal output, see Table 12 on Page
35 for examples with and without 8 lines display offset for different MUX. It should be noted that after
changing the display multiplex ratio, the bias ratio need to be adjusted to make display contrast consistent.
9.25 Set Bias Ratio
Except the 1/4 bias, all other available bias ratios could be selected using this command plus the “Set LCD
Bias” command. For detail setting values and POR default, please refer to the extended command table,
Table 9 on Page 26.
9.26 Set Temperature Coefficient (TC) Value
One out of 4 different temperature coefficient settings is selected by this command in order to match various
liquid crystal temperature grades. Please refer to the extended command table, Table 9 on Page 26, for
detailed TC values.
9.27 Modify Oscillator Frequency
The oscillator frequency can be fine tuned by applying this command. Since the oscillator frequency will be
affected by some other factors, this command is not recommended for general usage. Please contact
Solomon Systech application engineers for more detail explanation on this command.
SSD1805 Series

Solomon Systech
9.28 Set 1/4 Bias Ratio
This command sets the bias ratio directly to 1/4. This bias ratio is especially designed for use in under 12
MUX display. In order to restore to other bias ratio, this command must be executed, with LSB=0, before the
“Set Multiplex ratio” or “Set LCD Bias” command is sent.
9.29 Set Icon Enabled
This command enables or disables the icon. It should be noticed that the default setting (POR) will enable the
icon.
9.30 Set Display Offset
This command should be sent ONLY when the multiplex ratio is set less than the default value.
When a lesser multiplex ratio is set, the display will be mapped in the top (y-direction) of the LCD, see the no
offset columns on Table 3 on Page 15. Use this command could move the display vertically within the 67
commons. To make the Reduced-MUX Com 0 (Com 0 after reducing the multiplex ratio) towards the Row 0
direction for L lines, the 7-bit data in second command should be given by L. An example for 8 line moving
towards to Com 0 direction is given on Table 12 on Page 35. To move in the other direction by L lines, the 8bit data should be given by 67-L. Please note that the display is confined within the default multiplex value.
9.31 Set Total Frame Phases
The total number of phases for one display frame is set by this command. The Static Icon is generated by the
overlapping of M and MSTAT signals. These two pins output either VSS or VDD at same frequency but with
phase different. To turn on the Static Icon, 3 phases overlapping is applied to these signals, while 1 phase
overlapping is given to the off status. The more the total number of phases in one frame, the less the
overlapping time. Thus the lower the effective driving voltage at the Static Icon on the LCD panel.
9.32 Status register Read
This command is issued by pulling D/ C Low during a data read (refer to Figure 11 on Page 40 and Figure 13
on Page 42 for parallel interface waveforms). It allows the MCU to monitor the internal status of the chip. No
status read is provided for serial mode.

Maximum ratings are those values beyond which damages to the device may occur. Functional operation should be restricted to the limits in the Electrical
Characteristics tables or Pin Description section.
This device contains circuitry to protect the inputs against damage due to high static voltages or 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. For proper operation it is
recommended that VCI and VOUT be constrained to the range VSS < or = (VCI or VOUT) < or = VDD. Reliability of operation is enhanced if unused input is
connected to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. This 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.
