1. DESCRIPTION
2. FEATURES
S1D15G10 series are the LCD drivers equipped with
the liquid crystal drive power circuit to realize color
display with one chip.
S1D15G10 can be directly connected to the MPU bus to
store parallel or serial gray-scale display data from
MPU on the built-in RAM and to generate liquid crystal
drive signals independent from MPU. S1D15G10
generates 396 segment outputs and 132 common outputs
for driving liquid crystal. It incorporates the display
RAM with capacity of 396 × 132 × 4 (16 gray-scale). A
single dot of pixel on the liquid crystal panel corresponds
to 4 bits of the built-in RAM, enabling to display 132
(RGB) × 132 pixels with one chip.
Read or write operations from MPU to the display RAM
can be performed without resorting to external actuating
clock signals. S1D15G10 allows you to run the display
system of high performance and handy equipment at the
minimum power consumption thanks to its low-power
liquid crystal drive power circuit and oscillation circuit.
• Number of liquid crystal-drive outputs:
396 segment outputs and 132 common outputs.
• Low cross talk by frame rate modulation.
• 256 color from 4096-color display or full 4096-color
display.
When 256 color from 4096-color display is selected:
8 gray-scale for red and green and 4 gray-scale for
blue (intermediate tone is selected with the command).
When 4096-color display is selected: 16 gray-scale
for red, green and blue.
• Direct data display with display RAM
(When the LCD is set to normally black)
RAM bit Data “0000” ... OFF (Black)
“1111” ...ON (Maximum RGB display)
(Normally black LCD, using "inverse display" command)
• Partial display function: You can save power by
limiting the display space. This function is most
suited for handy equipment in the standby mode.
• Display RAM : 396 × 132 × 4 = 209,088 bits.
• MPU interface: S1D15G10 can be directly connected
to both of the 8/16-bit parallel 80 and 68 series MPU.
Two type serial interface are also available.
• 3 pins serial : CS, SCL and SI (D/C + 8-bit data)
• 4 pins serial : CS, SCL, SI and A0
• Abundant command functions: Area scroll function,
automatic page & column increment function, display
direction switching function and power circuit control
function.
• Built-in liquid crystal drive power circuit: S1D15G10
is equipped the charge pump booster circuit, voltage
follower circuit and electric volume control circuit.
• Oscillation circuit with built-in high precision CR
(external clock signals acceptable)
• EEPROM interface functions
• Supply voltage
Power for input/output system power:
VDDI –GND=1.7V to 3.6V
Power for internal circuit operation:
VDD–GND=2.6V to 3.6V
Reference power for booster circuit:
VDD2–GND=2.6V to 3.6V
Power for liquid crystal drive:
V3 –MV3=12.0V to 21.0V
• Wider operational range: –40°C to +85°C.
• Shipping from: Chip with gold bump. COF.
• Note that the radiation resistant design or light
resistance design in strict sense is not employed for
S1D15G10.

Relation between Data Bus and Gradation Data
S1D15G10 offers the 256-color display (8 gray-scale) out of 4096 colors as well as the 4096-color display (16 grayscale). When using 256-color display out of 4096 colors, you can specify color for each of R, G and B using the palette
function.
When using 4096 colors for display, you can select the type A or type B display mode depending on the data bus and
RGB you use. Use the data control command for switcing between these modes.
(1) 256-color display out of 4096 colors
Using RGBSET8 command enables you to set color for each of R, G and B by turning on the palette function
prepared to convert 3- or 2-bit data to 4-bit data.
1 8-bit mode
D7, D6, D5, D4, D3, D2, D1, D0: RRRGGGBB (8 bits) data is converted to RRRRGGGGBBBB (12 bits) and then
stored on the display RAM.

8.1.3 8- and 9-bit Serial Interface
The 8-bit serial interface uses four pins - CS, SI, SCL and A0 - to enter commands and data. Meanwhile, the 9-bit serial
interface uses three pins - CS, SI and SCL - for the same purpose.
Data read is not available with the serial interface. Data entered must be 8 bits. Refer to the following chart for entering
commands, parameters or gray-scale data.
The relation between gray-scale data and data bus in the serial input is the same as that in the 8-bit parallel interface
mode (described in the preceding section) at every gradation.
(1) 8-bit serial interface
When entering data (parameters): A0 = HIGH at the rising edge of the 8th SCL.

* If CS is caused to HIGH before 8 bits from D7 to D0 are entered, the data concerned is invalidated. Before entering
succeeding sets of data, you must correctly input the data concerned again.
* In order to avoid data transfer error due to incoming noise, it is recommended to set CS at HIGH on byte basis to
initialize the serial-to-parallel conversion counter and the register.
* When executing the command RAMWR, set CS to HIGH after writing the last address (after starting the 9th pulse
in case of 9-bit serial input or after starting the 8th pulse in case of 8-bit serial input).

8.2 Access to DDRAM and Internal Registers
S1D15G10 realizes high-speed data transfer because the access from MPU is a sort of pipeline processing done via the
bus holder attached to the internal, requiring the cycle time alone without needing the wait time.
For example, when MPU writes data to the DDRAM, the data is once held by the bus holder and then written to the
DDRAM before the succeeding write cycle is started. When MPU reads data from the DDRAM, the first read cycle
is dummy and the data read in the dummy cycle is held by the bus holder, and then it is read from the bus holder to the
system bus in the succeeding read cycle. Fig. 8.2.1 illustrates these relations.

* There is a restriction in the read sequence of the DDRAM. Namely, the data at the specified address is not output

data read.

8.3 DDRAM
8.3.1 DDRAM
It is 396 × 132 × 4 bits capacity RAM prepared for storing dot data. You can access a desired bit by specifying the page
address and column address.
Since display data from MPU - D7 to D0 and D16 to D8 - correspond to one or two pixels of RGB, data transfer-related
restrictions are reduced, realizing the display flexibly.
The RAM on S1D15G10 is separated to a block per 4 line to allow the display system to process data on the block basis.
MPU’s read and write operations to and from the RAM are performed via the I/O buffer circuit. Reading of the RAM
for the liquid crystal drive is controlled from another separate circuit.
Refer to the following memory map for the RAM configuration.

8.3.2 Page Address Control Circuit
This circuit is used to control the address in the page direction when MPU accesses the DDRAM or when reading the
DDRAM to display image on the LCD.
You can specify a scope of the page address (start and end page) with PASET (page address set) command. When the
page-direction scan is specified with DATCTL (data control) command and the addresses are incremented from the start
up to the end page, the column address is incremented by 1 and the page address returns to the start page.
The DDRAM supports up to 132 lines, and thus the total page becomes 132.
In the read operation, as the end page is reached, the column address is automatically incremented by 1 and the page
address is returned to the start page.
Using the address normal/inverse parameter of DATCTL command allows you to inverse the correspondence between
the DDRAM address and common output.
8.3.3 Column Address Control Circuit
This circuit is used to control the address in the column direction when MPU accesses the DDRAM. You can specify
a scope of the column address (start and end column) using CASET (column address set). When the column-direction
scan is specified with DATCTL command and the addresses are incremented from the start to the end up to the end
column, the page address is incremented by 1 and the column address returns to the start column.
In the read operation, too, the column address is automatically incremented by 1 and returns to the start page as the end
column is reached.
Just like the page address control circuit, using the column address normal/inverse parameter of DATCTL command
enables to inverse the correspondence between the DDRAM column address and segment output. This arrangement
relaxes restrictions in the chip layout on the LCD module.
8.3.4 I/O Buffer Circuit
It is the bi-directional buffer used when MPU reads or writes the DDRAM. Since MPU’s read or write of the DDRAM
is performed independently from data output to the display data latch circuit, asynchronous access to the DDRAM while
the LCD is turned on does not cause troubles such as flicking of the display images.
8.3.5 Block Address Circuit
This circuit associates pages on the DDRAM with COM output. S1D15G10 processes signals for the liquid crystal
display on 4-page basis (block basis). Thus, when specifying a specific area in the area scroll display or partial display,
you must designate it in block.
8.3.6 Display Data Latch Circuit
This circuit is used to temporarily hold display data to be output from the DDRAM to the SEG decoder circuit. Since
DISNOR/DISINV (display normal/inverse) and DISON/DISOFF (display on/display off) commands are used to
control data in the latch circuit alone, they do not modify data in the DDRAM.

8.4 Area Scroll Display
Using ASCSET (area scroll set) and SCSTART (scroll start set) commands allows you to scroll the display screen
partially. You can select any one of the following four scroll patterns.
Center screen scroll

When, for example, 1/120 duty (Display area: 30 blocks = 120 lines) is selected, and the top 2 blocks = 8 lines and bottom
2 blocks = 8 lines are specified as the fixed areas and the remaining 26 blocks = 104 lines as the scroll area, 3 blocks
= 12 lines on the DDRAM can be used as the background area.

Using PTLIN (partial in) command allows you to turn on the partial display (division by line) of the screen. This mode
requires less current consumption than the whole screen display, making it suitable for the mobile equipment in the
standby state.

8.7 Oscillation Circuit
S1G15G10 contains the oscillation circuit whose operation does not require any external part. The oscillation circuit
is enabled only when M/S = HIGH and CLS = HIGH. When the external clock signal is (CLS = LOW or M/S = LOW),
the clock is entered from CL pin.
8.8 Display Timing Generation Circuit
This circuit generates the timing signal for display (CL, FR, SYNC, CA, F1, F2, DOFF) using the clock from the builtin oscillation circuit or the external clock.
It is also used to generate the clock to turn on the liquid crystal-drive power circuit.
When using S1D15G10 in multi-chip array, the display timing signal (CL, FR, SYNC, CA, F1, F2, DOFF) must be sent
from the master to the slave.
8.9 SEG Decoder Circuit
This circuit outputs the segment driver control signal based on display data for 4-page and the timing signal.
8.10 Liquid Crystal Drive Circuit
It outputs liquid crystal drive voltage. Responding to the decoder output signal and the display-timing signal, the
segment output pin outputs one of potentials V2 , V1 , VC, MV1 or MV 2 and the common output pin outputs one of
potentials V3 , VC or MV3 .

8.11 Liquid Crystal-Drive Power Circuit
The power circuit contained in S1D15G10 generates voltage required to drive liquid crystal. This low power
consumption type power circuit is consisted the voltage regulator, booster circuits (primary, secondary) and voltage
follower. The power circuit is enabled only when the master operation mode is turned on.
The power control circuit turns on or off the voltage regulator, booster circuits, Reference voltage generation circuit
and voltage follower responding to PWRCTR (power control set) command. Thus, function of the external and internal
power supplies can be partly used in parallel.
Table 8.11.1 lists the functions controlled by the 4-bit data - parameter of PWRCTR. Table 8.11.2 shows combinations
of 4 bits (combinations shown in Table 8.11.2 alone are valid).

8.11.4 Voltage Regulator Circuit
The voltage regulator circuit generates the liquid crystal drive voltage V1 using VCSL from the primary booster circuit.
S1D15G10 incorporates the high-precision constant voltage source, 64-step electronic volume control function and
resistor to regulate V1 voltage. The voltage regulator circuit covers a wider temperature range with fewer numbers of
parts thanks to the temperature gradient control function as well as the temperature sensing function.
However, capacitors may be required for voltage regulation between V1 and GND pins due to the load of LCD panel.
Insert the capacitors, if necessary, by observing the voltage waveforms and current consumption.
(A) Built-in Resistor for V1 Voltage Regulation
Using this resistor and the electronic volume control function allows you to control the liquid crystal drive voltage V1
to an optimum level for the LCD panel with the command alone, without resorting to external resistors.
V1 output voltage can be determined from Equation A-1 as long as the relation V1 < VCSL is met.
However, set the voltage of V1 by allowing for a drop in the voltage due to load, so that it becomes at or below 80 %
of VCSL.

Capacitors may be required for voltage regulation between the GND and each of VC pin due to the load of LCD panel.
Insert the capacitors, if necessary, by observing the voltage waveforms and current consumption.
The following theoretical equation is the potential relationship.
When the capacitor C is connected between CAP2+ and CAP2– and between V2 and GND, the primary booster boosts
the voltage from V1 and MV1 and generates V2.
VC = 2/3 × V 1
MV1 = 1/3 × V1

(1) Display ON (DISON) Command: 1 Parameter: None
It is used to turn the display on. When the display is turned on, segment outputs and common outputs are generated
at the level corresponding to the display data and display timing. You can’t turn on the display as long as the sleep mode
is selected. Thus, whenever using this command, you must cancel the sleep mode first.

A block address that can be specified for the partial display must be the displayed one (don’t try to specify an address
not to be displayed when scrolled).
When the partial display mode is turned on, following state is introduced to S1D15G10 in the non-display area:
* LOW is output to DOFF pin.
* All COM pins output VC.
* All SEG pins output V1 or MV1.
SEG output is forced to V1 or MV1 depending on state of FR in the last display line. When FR is HIGH, V1 is output
and when FR is LOW, MV1 is output. Phase of FR is constantly reversed at start of a frame.

cursor. First set a specific display area using the column and page address commands. Then, enter this command to
set the column and page addresses at the start address of the specific area. When this operation is complete, the column
(page) address won’t be modified by the display data read command. It is incremented only when the display data write
command is used. You can cancel this mode by entering the read modify write out or any other command.

Since S1D15G10 processes the liquid crystal display signals on the four-line basis (block basis), FIX and scroll areas
are also specified on the four-line basis (block basis).
DDRAM address corresponding to the top FIX area is set in the block address incrementing direction starting with 0
block. DDRAM address corresponding to the bottom FIX area is set in the block address decreasing direction starting
with 41st block. Other DDRAM blocks excluding the top and bottom FIX areas are assigned to the scroll + background
areas.
P1: It is used to specify the top block address of the scroll + background areas. Specify the 0th block for the top screen
scroll or whole screen scroll.
The scroll start block address is also set at this top block address until the scroll-start block set command specifies
the address.
P2: It specifies the bottom address of the scroll + background areas. Specify the 32th block for the bottom or whole
screen scroll.
Required relation between the start and end blocks (top block address < bottom block address) must be maintained.
P3: It specifies a specific number of blocks {Numbers of (Top FIX area + Scroll area) blocks - 1}. When the bottom
scroll or whole screen scroll, the value is identical with P2.
You can turn on the area scroll function by executing the area scroll set command first and then specifying the display
start block of the scroll area with the scroll start set command.

12.2.2 Command Input Procedure During Power Off
•When power-on reset is not used
<< IC status>>
Display off (DISOFF): display is turned off, and all of the common and segment pins become VC potential.
Liquid crystal drive power supply circuit off (PWRCTR): built-in power supply circuit stops.
Oscillation off (OSCOFF): built-in oscillation circuit stops and all the circuits inside the IC also stop.
Sleep In (SLPIN) *2
Stop the power supply (VDDI, VDD).
*2: In order to discharge the capacitor connected to the liquid crystal drive power supply circuit, execute the Sleep In
command to put the IC in Sleep state prior to stopping the power supply. Stop VDDI and VDD when the output of
the liquid crystal drive power supply circuit has dropped sufficiently.
•When power-on reset is used
Turn on the power-on reset (RES = LOW) *3
Stop the power supply (VDDI , VDD).
*3: Stop VDDI and VDD when the output of the liquid crystal drive power supply circuit has dropped sufficiently.
(Note:1)
This IC is the logic circuit of the VDD-GND and VDDI-GND power supplies, and it controls the liquid crystal output
driver. If the VDDI-GND and VDD-GND power supplies are stopped with residual voltage in the liquid crystal drive
power supply circuit, the liquid crystal output driver (COM, SEG) may output uncontrolled voltage. Stop VDDI and
VDD when the output of the liquid crystal drive power supply circuit has dropped sufficiently.
(Note:2)
Avoid writing in the display RAM during sleep-in since it may cause too much current to be generated.
12.2.3 Sleep state
This IC goes into Sleep state when the Sleep In command and several other commands are executed. When in the Sleep
state, IC power consumption will be kept to a minimum. Also, internal status including the display RAM will be
maintained, the Sleep Out and several commands will resume the display state.
•Setting the Sleep state
<< IC status>>
1 Display off (DISOFF): display is turned off, and all the common segment and pins become VC potential.
2 Liquid crystal drive power supply circuit off (PWRCTR): built-in power supply circuit stops.
3 Oscillation off (OSCOFF): built-in oscillation circuit stops and all the circuits inside the IC also stop.
Sleep In (SLPIN): commands other than 1 to 3 and display RAM content are maintained. Commands can be entered.
(Note) Avoid writing in the display RAM during sleep-in since it may cause too much current to be generated.
•Releasing the Sleep state
<<IC status>>
Sleep Out (SLPOUT)
Oscillation on (OSCON): built-in power supply circuit operates and liquid crystal drive potential is supplied.
56
EPSON
Rev. 1.0
S1D15G10D08B000
Wait (approx. 100ms): wait until liquid crystal drive power supply boots and stabilizes. Wait until the power supply
voltage stabilizes.
Display on (DISON): display comes on and the display RAM content is output.
12.2.4 Refresh Sequence
Refreshing of the state setup is recommended by reentering the command, parameters and the display data in order to
recover from improper IC operations due to such reasons as noise.
Reconfigure the following commands and parameters.
Common scan direction (COMSCN)
Temperature gradient (TMPGRD)
Oscillation on (OSCON)
Sleep Out (SLPOUT)
Electronic volume control (VOLCTR)
Power supply control (PWRCTR)
Normal (DISNOR)/Inverted display (DISINV)
Partial in (PTLIN)/Partial out (PTLOUT)
Area scroll set (ASCSET)
Scroll start set (SCSTART)
Data control (DATCTL)
256-color position set (RGBSET8)
NOP instruction (NOP) *1
Page address set (PASET)
Column address set (CASET)
Memory write command (RAMWR): display data write
Display on (DISON)
*1: IC shipment inspection test state can be escaped with NOP instruction. Add this to the refresh sequence.
If display control (DISCTL) is reconfigured during display, noise may occur on the display, so omit this from the refresh
sequence. Reconfigure with the display off.

built-in resistance ratio using the read data.
Miscellaneous:
The MPU can read the Electronic Control value and built-in resistance ratio by issuing a combination of EPSRRD1 or
EPSRRD2 and STREAD (Status Read) commands.
Notes: As the EPCTIN, EPCWR and EPCRD commands require the following processing times, use a software
timer or insert a process to loop the operation by monitoring the status read value of D2 (Access to
EEPROM). If these times are insufficient, the Read or Write operation may fail.

Users are requested to pay attention to the following points when using S1D15G10 series.
Precautions on Light
Characteristics of semiconductor devices can be changed when exposed to light as described in the operational
principles of solar batteries. Exposing this IC to light, therefore, can potentially lead to its malfunctioning.
1 Care must be exercised in designing the operation system and mounting the IC so that it may not be exposed light
during operation
2 Care must be exercised in designing the inspection process and handling the IC so that it may not be exposed to light
during the process.
3 The IC must be shielded from light in the front, back and side faces.
Precautions on External Noises
1 Internal state of S1D15G10 can be changed when exposed to adversely affecting external factors such as excessive
noises though it can maintain the command-instructed operational status and display data. Thus, you must make
sure when mounting the IC and designing the operation system that measures for eliminating noises or measures
protecting the IC from noises are prepared.
2 In order to be prepared against sudden noise, it is recommended to prepare the software to perform periodic
refreshing of operational state (re-setting of commands and re-transfer of display data).
Precautions on Mounting COG
When mounting COG, you must take into consideration of resistance component generated across the driver chip and
externally connected parts (capacitor and resistor) resulting from ITO wiring. This resistance component can interfere
with high-speed operation of liquid crystal display or MPU.
When mounting COG, you must take into consideration of the following three points in the module design:
1. To minimize resistance between the driver chip pin to the external part.
2. To minimize resistance at the power terminal of the driver chip.
3. To develop sample COG modules with varying degrees of ITO sheet resistance in order to select one with the sheet
resistance allowing sufficient operational margins.
