FUNCTIONAL BLOCK DESCRIPTIONS
7.1
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 is high, data is written to
Graphic Display Data RAM (GDDRAM). If D/C is low, the input at D0 -D7 is interpreted as a
Command and it will be decoded and written to the corresponding command register.
Reset is of the same function as Power ON Reset (POR). Once RES# receives a negative reset
pulse of about 1us, all internal circuitry will be back to its initial status. Refer to Command
Description section for more information.
7.2
MPU Parallel 6800-series Interface
The parallel interface consists of 8 bi-directional data pins (D0 - D7), R/W(WR#), D/C, E(RD#)
and CS#. 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#)
and CS# input serves as data latch signal (clock) when they are high and low respectively.
Refer to Figure 10 of parallel timing characteristics for Parallel Interface Timing Diagram of
6800-series microprocessors.
In order to match the operating frequency of display RAM with that of the microprocessor, 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 below.

7.3
MPU Parallel 8080-series Interface
The parallel interface consists of 8 bi-directional data pins (D0 - D7), R/W(WR#), E(RD#), D/C
and CS#. The CS# input serves as data latch signal (clock) when it is low. Whether it is display
data or status register read is controlled by D/C. R/W(WR#) and E(RD#) input indicates a write
or read cycle when CS is low. Refer to Figure 12 of parallel timing characteristics for Parallel
Interface Timing Diagram of 8080-series microprocessor.
Similar to 6800-series interface, a dummy read is also required before the first actual display
data read.

SOLOMON
7.4
MPU Serial 4-wire Interface
The serial interface consists of serial clock SCK, serial data SDA, D/C and CS#. SDA is shifted
into a 8-bit shift register on every rising edge of SCK in the order of D7, D6, ... D0. D/C is
sampled on every eighth clock and the data byte in the shift register is written to the Display
Data RAM or command register in the same clock. No extra clock or command is required to
end the transmission.
7.5
MPU Serial 3-wire interface
Operation is similar to 4-wire serial interface while D/C is not been used. The Display Data
Length instruction is used to indicate that a specified number display data byte(s) (1-256) are to
be transmitted. Next byte after the display data string is handled as a command.
It should be noted that if there is a signal glitch at SCK that causing an out of synchronization in
the serial communication, a hardware reset pulse at RES# pin is required to initialize the chip
for re-synchronization.

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 96 x 65 = 6,240bits for SSD1828. Figure 5 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 5 shows the case in
which the display start line register is set at 30H.
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.

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. 2X, 3X, 4X and 5X DC-DC voltage converter
2. Bias Divider
If the output op-amp buffer option in Set Power Control Register command is enabled, this circuit
block will divide the regulator output (Vout) to give the LCD driving levels (VL2 - VL5).
The divider does not require external capacitors to reduce the external hardware and pin counts.
3. Contrast Control
Software control of 64 voltage levels of LCD voltage.
4. Bias Ratio Selection circuitry
Software control of 1/4 to 1/9 bias ratio to match the characteristic of LCD panel.
5. Self adjust temperature compensation circuitry
Provide 4 different compensation grade selections to satisfy the various liquid crystal temperature
grades. The grading can be selected by software control. Defaulted temperature coefficient
(PTC3) value is -0.05%/°C.
7.9
161 Bit Latch
A register carries the display signal information. In 96 X 65 display-mode, data will be fed to the
HV-buffer Cell and level-shifted to the required level.
7.10 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.
7.11 HV Buffer Cell (Level Shifter)
HV Buffer Cell works as a level shifter, which translated 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.

This command turns the display on/off, by the value of the LSB.
8.2
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 63. 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. The display start
line values of 0 to 63 are assigned to Page 0 to 7.
8.3
Set Page Address
This command positions the page address to 0 to 8 possible positions in GDDRAM. Refer to
Figure 5.
8.4
Set Higher 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 data access after it is pre-set by the MCU and
returning to 0 once overflow (>95).
8.5
Set Lower Column Address
This command specifies the lower nibble of the 7-bit column address of the display data RAM.
The column address will be incremented by each data access after it is pre-set by the MCU and
returning to 0 once overflow (>95).
8.6
Set Temperature Coefficient (TC) Value
This command is to set 1 out of 4 different temperature coefficients in order to match various
liquid crystal temperature grades.
8.7
Set Segment Re-map
This commands changes the mapping between the display data column address and segment
driver. It allows flexibility in layout during LCD module assembly. Refer to Figure 5.
8.8
Set Normal/Reverse Display
This command sets the display to be either normal/reverse. In normal display, a RAM data of 1
indicates an “ON” pixel while in reverse display; a RAM data of 0 indicates an “ON” pixel. The
icon line is not affected by this command.
8.9
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/reverse display.
To execute this command, Set Display On command must be sent in advance.
8.10 Set LCD Bias
This command selects a suitable bias ratio (1/4 to 1/9) required for driving the particular LCD
panel in use. The POR is set to 1/9 bias.

This command enable/disable the Icon displays.
8.24 Start Internal Oscillator
After POR, the internal oscillator is OFF. It should be turned ON by sending this command to
the chip.
8.25 Set Display Data Length
This two-bytes command only valid when 3-wire SPI configuration is set by H/W input
(PS0=PS1=L). The second 8-bit is used to indicate that a specified number display data byte(s)
(1-256) are to be transmitted. Next byte after the display data string is handled as a command.
8.26 Set Test Mode
This command forces the driver chip into its test mode for internal testing of the chip. Under
normal operation, user should NOT use this command.

8.27 Status Register Read
This command is issued by setting D/C Low during a data read (refer to figure 1 and 2 parallel
interface waveform). It allows the MCU to monitor the internal status of the chip. No status read
is provided for serial mode.
EXTENDED COMMANDS
These commands are used, in addition to basic commands, to trigger the enhanced features, on top of
general ones, designed for the chip.
8.28 Enable external oscillator input.
This command enables the external clock input from CL pin and expected external square wave
is 58.5kHz.

* Maximum Ratings are those values beyond which damage 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 Vin and Vout be constrained to range VSS < or = (Vin or Vout) < or = VDD. Reliability of
operation is enhanced if unused inputs are connected to an appropriate logic voltage level (e.g. either VSS
or VDD). Unused outputs must be open. This device may be light sensitive. Caution should be taken to
avoid exposure of this device any light source during normal operation. This device is not radiation
protected.
