ST7669V
262K 132x162 Color Dot Matrix LCD Controller/Driver
1 INTRODUCTION
The ST7669V is a driver & controller LSI for 262K color graphic dot-matrix liquid crystal display systems. It generates 396
segments and 162 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface or 8-bit/16-bit/18-bit parallel display data and stores in an on-chip display data RAM. It performs display data RAM
read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power
supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

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 in the serial interface. Data entered must be 8 bits. 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 at every gradation.

If /CS is set to HIGH while the 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.

7.2 ACCESS TO DDRAM AND INTERNAL REGISTERS
ST7669V 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 bus holder holds the data read in the dummy cycle, and then it read from the bus holder to the system bus
in the succeeding read cycle. Figure 7.2-1 illustrates these relations.

Address Control
The address counter sets the addresses of the display data RAM for writing.
Data is written pixel into the RAM matrix of ST7669V. The data for one pixel or two pixels is collected (RGB 6-6-6 bit),
according to the data formats. As soon as this pixel-data information is complete, the “Write access” is activated on the
RAM. The locations of RAM are addressed by the address pointers. The address ranges are X=0 to X=131 (83h) and Y=0
to Y=161 (A1h). Addresses outside these ranges are not allowed.
Before writing to the RAM, a window must be defined into which will be written. The window is programmable via the
command registers XS, YS designating the start address and XE, YE designating the end address.
For example the whole display contents will be written, the window is defined by the following values: XS=0 (0h) YS=0 (0h)
and XE=131 (83h), YE=161 (A1h).
In vertical addressing mode (MV=1), the Y-address increments after each byte, after the last Y-address (Y=YE), Y wraps
around to YS and X increments to address the next column. In horizontal addressing mode (MV=0), the X-address
increments after each byte, after the last X-address (X=XE), X wraps around to SC and Y increments to address the next
row. After the every last address (X=XE and Y=XE) the address pointers wrap around to address (X=XS and Y=YS). For
flexibility in handling a wide variety of display architectures, the commands “CASET, RASET” and “MADCTR” , define flags
MX, MY and MV, which allows mirroring of the X-address and Y-address. All combinations of flags are allowed. Figure
7.3-1 show the available combinations of writing to the display RAM. When MX, MY and MV will be changed the data must
be rewritten to the display RAM.
For each image condition, the controls for the column and row counters apply as below:

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 DDRAM is
performed independently from data output to the display data latch circuit, asynchronous access to the DDRAM when the
LCD is turned on does not cause troubles such as flicking of the display images.
7.3.4
Scroll Address Circuit
The circuit associates pages on DDRAM with COM output. ST7669V processes signals for the liquid crystal display on
1-page basis. Thus, when specifying a specific area in the area scroll display or partial display, you must designate it in
block.
7.3.5
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 display
normal/inverse and display on/off commands are used to control data in the latch circuit alone, they do not modify data in
the DDRAM.
7.3.6
Normal Display On or Partial Mode On Vertical Scroll Off
In this mode, contents of the frame memory within an area where column address is 00h to 83h and row address is 00h to
A1h is displayed.
To display a dot on leftmost top corner, store the dot data at (column address, row address) = (0,0).

There is just one types of vertical scrolling, which are determined by the commands “Vertical Scrolling Definition” (33h) and
“Vertical Scrolling Start Address” (37h).

Example 1: MPU Write is faster than Panel Read.
Data write to Frame Memory is now synchronized to the Panel Scan. It should be written during the vertical sync pulse of
the Tearing Effect Output Line. This ensures that data is always written ahead of the panel scan and each Panel Frame
refresh has a complete new image:

Example 2: MPU Write is slower than Panel Read.
The MPU to Frame Memory write begins just after Panel Read has commenced i.e. after one horizontal sync pulse of the
Tearing Effect Output Line. This allows time for the image to download behind the Panel Read pointer and finishing
download during the subsequent Frame before the Read Pointer “catches” the MPU to Frame memory write position.

7.4 GRAY-SCALE DISPLAY
ST7669V incorporates a 4FRC & 31 PWM function circuit to display a 64 gray-scale display.
7.5 OSCILLATION CIRCUIT
ST7669V is built-in an oscillator circuit. It provides internal clock without external resistor. This oscillator signal is used in
the voltage converter and display timing generation circuit.
7.6 DISPLAY TIMING GENERATOR CIRCUIT
This circuit generates some signals to be used for displaying LCD. The display clock, which is generated by oscillation
clock, generates the clock for the line counter and the signal for the display data latch. The line address of on-chip RAM is
generated in synchronization with the display clock and the display data latch circuit latches the display data in
synchronization with the display clock. The display data, which is read to the LCD driver, is completely independent of the
access to the display data RAM from the microprocessor. The display clock generates an LCD AC signal (M), which
enables the LCD driver to make an AC drive waveform, and also generates an internal common timing signal and start
signal to the common driver. The frame signal or the line signal changes the M by setting internal instruction. Driving
waveform and internal timing signal are shown in Figure 7.3-3.

7.7 POWER LEVEL DEFINITION
7.7.1
Power ON/OFF SEQUENCE
During power off, if LCD is in the Sleep Out mode, VDD and VDDI must be powered down minimum 200msec after /RST
has been released. During power off, if LCD is in the Sleep In mode, VDDI or VDDA can be powered down minimum
0msec after /RST has been released.
/CS can be applied at any timing or can be permanently grounded. /RST has priority over /CS.
There will be no damage to the display module if the power sequences are not met.
There will be no abnormal visible effects on the display panel during the Power On/Off Sequences.
There will be no abnormal visible effects on the display between end of Power On Sequence and before receiving Sleep
Out command. Also between receiving Sleep In command and Power Off Sequence.
If /RST line is not held stable by host during Power On Sequence as defined in Sections case1 and case2, then it will be
necessary to apply a Hardware Reset (/RST) after Host Power On Sequence is complete to ensure correct operation.
Otherwise function is not guaranteed. The power on/off sequence is illustrated below:
Case 1 – /RST line is held High or Unstable by Host at Power On
If /RST line is held High or unstable by the host during Power On, then a Hardware Reset must be applied after both VDDA
and VDDI have been applied – otherwise correct functionality is not guaranteed. There is no timing restriction upon this
hardware reset.
Note: Unless otherwise specified, timings herein show cross point at 50% of signal/power level.
Ver 1.3
43/208
6/4/2008
ST7669V
Case 2 – /RST line is held Low by host at Power On
If /RST line is held Low (and stable) by the host during Power On, then the /RST must be held low for minimum 10µsec
after both VDD and VDDI have been applied.
Note: Unless otherwise specified, timings herein show cross point at 50% of signal/power level.
UNCONTROLLED POWER OFF
The uncontrolled power off means a situation when e.g. there is removed a battery without the controlled power off
sequence. There will not be any damages for the display module or the display module will not cause any damages for the
host or lines of the interface. At an uncontrolled power off the display will go blank and there will not be any visible effects
within 1 second on the display (blank display) and remains blank until “Power On Sequence” powers it up.

Power Levels
6 level modes are defined they are in order of Maximum Power consumption to Minimum Power Consumption:
1. Normal Mode On (full display), Idle Mode Off, Sleep Out:
In this mode, the display is able to show maximum 262K colors.
2. Partial Mode On, Idle Mode Off, Sleep Out:
In this mode part of the display is used with maximum 262K colors.
3. Normal Mode On (full display), Idle Mode On, Sleep Out:
In this mode, the full display area is used but with 8 colors.
4. Partial Mode On, Idle Mode On, Sleep Out:
In this mode, part of the display is used but with 8 colors.
5. Sleep In Mode:
In this mode, the DC:DC converter, Internal oscillator and panel driver circuit are stopped. Only the MCU interface and
memory works with Digital VDDI power supply. Contents of the memory are safe.
6. Power Off Mode:
In this mode, both Analog VDDA and Digital VDDI are removed.
Note: Transition between modes 1-5 is controllable by MCU commands. Mode 6 is entered only when both Power supplies
are removed.

VOLTAGE REGULATOR CIRCUITS
There is a built-in voltage regulator circuits in ST7669V for generating V0. After internal voltage is regulated by voltage
regulator circuit, V0 is generated. Detail explanation of V0 set is listed below:
SET V0 (Temperature = 24℃
℃)
V0=3.6+{Vop[8:0] + VopOffset[6:0]+ (EV[6:0]-3Fh)}x0.04
(V)
Example1 (V0 setting>16.48V):
Vop[8:0]=1 01000010 (142h)
VopOffset[6:0]=0000010 (02h)
EV[6:0]=0111111 (3Fh)
V0=3.6 + {322 + 2 + (63-63) } x 0.04 =16.56 (V)
Example2 (V0 setting<16.48V):
Vop[8:0]= 1 01000010 (142h)
VopOffset [6:0]=1000010 (42h)
EV[6:0]=0111111 (3Fh)
V0=3.6 + {322 -62 + (63-63) } x 0.04 =14 (V)
V0 restriction:
Because Vg should larger than 1.8V, ST7669V V0 value should be higher than 1.8 x Bias / 2 (V) and lower than 18V.
V0 value outside the available range is undefined. Users has to ensure while selecting the temperature compensation that
under all conditions and including all tolerances that the V0 voltage remains in the range.

V0 fine tuning
ST7669V has 2 commands for fine tuning V0. These commands are VopOfsetInc (see section 9.1.50) and
VopOfsetDec (see section 9.1.51 ). When writing VopOfsetInc into IC for each time, V0 would increase 40mV; when writing
VopOfsetDec into IC for each time, V0 would decrease 40mV.
Example:
Vop[8:0]=1 01000010 (142h)
VopOffset[6:0]=0000010 (02h)
EV[6:0]=0111111 (3Fh)

OTP SETTING FLOW
ST7669V provides the Write and Read function to write the electronic control value and built-in resistance ratio into
OTP (One-time programming register), and then read them from it. Using the Write and Read functions, you can store
these values appropriate to each LCD panel. This function is very convenient for user in setting from some different panel’s
voltage. But using this function must attention the setting procedure. Please see the following diagram.
Figure 7.3-6
OTP programming flow
Note1: This setting flow is used for LCM assembler.
Note2: OTP shouldn’t be written without preceding loading correctly from OTP in order to avoid some
errors during IC operation.
Note3: When writing value to OTP, the voltage of VPP must be 7.5V~7.75V; the current of Ivpp must be
more than 4 mA.
Note4: If the OTP is exposed to a high temperature for hours, data in the memory cell may probably be
lost before the data retention guarantee period. To retain data in the memory cell, keep the memory cell
below 90℃. The data retention guarantee period is specified including the retention period.

REGISTER LOADING DETECTION
ST7669V will auto-switch frame rate on different temperature such as Figure 7.3-7. TA, TB and TC are frame rate
switching temperatures which can be defined by customer with command TMPRNG. FA, FB, FC and FD are switched
frame rate which also can be defined by customer with command FRMSEL. The frame rate range is from 18.75Hz to
170Hz.
When the temperature is in increasing state, frame rate changes to the higher step at TA/TB/TC+TH(℃). When the
temperature is in decreasing state, frame rate changes to the lower step at TA/TB/TC. For example: TC=10℃ and TH=5℃,
FC switches to FD at 15℃ but FD switches to FC at 10℃. Please take Figure 7.3-7 for reference.

7.10.1 Register loading Detection
Sleep Out-command is a trigger for an internal function of the display module, which indicates, if the display module loading
function of factory default values from OTP ROM (or similar device) to registers of the display controller is working properly.
There are compared factory values of the OTP ROM and register values of the display controller by the display controller
(1st step: compares register and OTP ROM values, 2nd step: loads OTP ROM values to registers). If those both values
(OTP ROM and register values) are same, there is inverted (= increased by 1) a bit, which is defined in command
RDDSDR) (The used bit of this command is D7). If those both values are not same, this bit (D7) is not inverted (= not
increased by 1).
The flow chart for this internal function is following:

7.10.2 Functionality Detection
Sleep Out-command is a trigger for an internal function of the display module.
The internal function (= the display controller) is comparing if the display module is still meeting functionality requirements
(e.g. booster voltage levels, timings, etc.). If functionality requirement is met, there is inverted (= increased by 1) a bit,
which defined in command Read Display Self-Diagnostic Result (0Fh)” (= RDDSDR) (The used bit of this command is D6).
If functionality requirement is not same, this bit (D6) is not inverted (= not increased by 1).
The flow chart for this internal function is following:
Note: There is needed 120msec after Sleep Out -command, when there is changing from Sleep In –mode to
Sleep Out -mode, before there is possible to check if functionality requirements are met and a value of RDDSDR’s D6 is valid. Otherwise,
there is 5msec delay for D6’s value, when Sleep Out –command is sent in Sleep Out -mode.

7.10.3 Chip Attachment Detection (Reserved)
Sleep Out-command is a trigger for an internal function of the display module, which indicates, if bump side of IC is
attached to LCM glass ITO or not.
There is inverted (= increased by 1) a bit, which is defined in command “Read Display Self-Diagnostic Result”
(RDDSDR). The used bit of this command is D5. If IC is not attached to the circuit route of the flex or display glass, this bit
(D5) is not inverted (= not increased by 1).
There are connected together 2 bumps via route of ITO on 4 corners of IC. TLBI connects to TLBO; TLUI connects to
TLUO; TRUI connects to TRUO; TRBI connects to TRBO.
7.10.4 LCM Glass Detection (Reserved)
Sleep Out-command is a trigger for an internal function of the display module, which indicates, if the display glass of
the display module is broken or not.
There is inverted (= increased by 1) a bit, which is defined in command “Read Display Self-Diagnostic Result (0Fh)”
(= RDDSDR).The used bit of this command is D4. If this display glass is broken, this bit (D4) is not inverted (= not
increased by 1).
The following figure is a reference of how this glass break detection can be implemented. For example, there is
connected together 2 bumps(TGI and TGO) via route of ITO. This route of ITO is the nearest route of the edge of the
display glass.

Parameter
Description
No parameter
This command causes the LCD module to enter the minimum power consumption mode.
In this mode e.g. the DC/DC converter, Internal oscillator, and panel scanning are all stopped.
MCU interface and memory are still working and the memory keeps its contents.
Restriction
This command has no effect when module is already in sleep in mode. Sleep In Mode can only be left
by the Sleep Out Command (11h).
It will be necessary to wait 5msec before sending next command, this is to allow time for the supply
voltages and clock circuits to stabilize.
It will be necessary to wait 120msec after sending Sleep Out command (when in Sleep In Mode)
before Sleep In command can be sent.

Parameter
Description
No parameter
This command turns off sleep mode. In this mode e.g. the DC/DC converter is enabled, Internal
oscillator is started, and panel scanning is started.
Restriction
This command has no effect when module is already in sleep out mode. Sleep Out Mode can only be
left by the Sleep In Command (10h).
It will be necessary to wait 5msec before sending next command, this is to allow time for the supply
voltages and clock circuits to stabilize.
The display module loads all display supplier’s factory default values to the registers during this 5msec
and there cannot be any abnormal visual effect on the display image if factory default and register
values are same when this load is done and when the display module is already Sleep Out –mode.
The display module is doing self-diagnostic functions during this 5msec.
It will be necessary to wait 120msec after sending Sleep In command (when in Sleep Out mode) before
Sleep Out command can be sent.

This command defines the partial mode’s display area. There are 2 parameters associated with
this command, the first defines the Start Line (PS) and the second the End Line (PE), as illustrated
in the figures below. PS and PE refer to the Frame Memory Line counter.
If End Line > Start Line when MADCTR ML=0:
If End Line > Start Line when MADCTR ML=1:
If End Line < Start Line when MADCTR ML=0:
* Row1: Frame memory row address 1.
If End Line = Start Line then the Partial Area will be one line deep.

Description
This command just defines the Vertical Scrolling Area of the display and not performs vertical scroll.
When MADCTL ML=0
The 1st parameter TFA [7:0] describes the Top Fixed Area (in No. of lines from Top of the Frame
Memory and Display).
The 2nd parameter VSA [7:0] describes the height of the Vertical Scrolling Area (in No. of lines of the
Frame Memory [not the display] from the Vertical Scrolling Start Address) The first line appears
immediately after the bottom most line of the Top Fixed Area.
The 3rd parameter BFA [7:0] describes the Bottom Fixed Area (in No. of lines from Bottom of the
Frame Memory and Display).
TFA, VSA and BFA refer to the Frame Memory Line Pointer.
Restriction
The condition is (TFA+VSA+BFA) = 162, otherwise Scrolling mode is undefined. In Vertical Scroll
Mode, MADCTL parameter MV should be set to ‘0’-this only affects the Frame Memory
Write.TFA[7:0], VSA[7:0] and BFA[7:0] are based on line unit.
TFA[7:0]= 00h, 01h, 02h, 03h, … , A1h

This command is used together with Vertical Scrolling Definition (33h). These two commands
describe the scrolling area and the scrolling mode.
The Vertical Scrolling Start Address command has one parameter which describes which line in the
Frame Memory will be written as the first line after the last line of the Top Fixed Area on the display as
illustrated below:
This command Start the scrolling.
Exit from V-scrolling mode by commands Partial mode On (12h) or Normal mode On (13h).
When MADCTL ML=0
Example:
When Top Fixed Area=Bottom Fixed Area=00, Vertical Scrolling Area=162 and Vertical Scrolling
Pointer SSA=’3’.
When MADCTL ML=1
Example:
When Top Fixed Area=Bottom Fixed Area=00, Vertical Scrolling Area=162 and Vertical Scrolling
Pointer SSA=’3’.
NOTE: When new Pointer position and Picture Data are sent, the result on the display will happen at
the next Panel Scan to avoid tearing effect.
SSA refers to the Frame Memory line Pointer.

Notes:
1. The reset cancel includes also required time for loading ID bytes, VCOM setting and other settings from EEPROM (or
similar device) to registers. This loading is done every time when there is HW reset cancel time (tRT) within 5 ms after a
rising edge of RST
2. Spike due to an electrostatic discharge on RST line does not cause irregular system reset according to the table
below:
RST Pulse
Action
Shorter than 5µs
Reset Rejected
Longer than 9µs
Reset
Between 5µs and 9µs
Reset starts
3. During the Resetting period, the display will be blanked (The display is entering blanking sequence, which maximum
time is 120 ms, when Reset Starts in Sleep Out –mode. The display remains the blank state in Sleep In -mode.) and then
return to Default condition for Hardware Reset.
4. Spike Rejection also applies during a valid reset pulse as shown below:
Ver 1.3
192/208
6/4/2008
ST7669V
5. When Reset applied during Sleep In Mode.
6. When Reset applied during Sleep Out Mode.
7. It is necessary to wait 5msec after releasing RST before sending commands. Also Sleep Out command cannot be sent
for 120msec.

16 ITO /FPC Layout Guide
16.1 ITO Layout of Power
VDD, VDD2~VDD5, VSS, VSS1, VSS2 & VSS4:
To avoid the noise in different power system affect other power system, please separate different power source on
ITO layout (VDD can be short together to get better performance).
To reduce the ITO resistance, the power source should have enough trace width (includes ITO width and FPC trace
width). So the separated ITO traces should be connected together by FPC.
=> The recommended solution is shown below.
IC Side
VDD3
VDD4
VDD5
VDD2
Separated by ITO
Short by ITO
FPC PIN
FPC PIN
FPC PIN
FPC PIN
Short on FPC
“Output”, “Input” and “Sensor” of built-in power circuits:
The V0, XV0 and Vg power circuits have output pins, input pins and a sensor input. To avoid the power noise affects
the sensor input of internal power circuits. The trace should be separated by ITO and should be connected together
by FPC. So that the “Sensor” pin has larger ITO resistance (for noise immunity).

The recommended layout topology is shown below:
VPP:
This is the power source for programming the internal OTP. If the ITO resistance is too high, the operation current
will cause the voltage drop while programming OTP. Please try to keep the ITO resistance as low as possible.

16.2 ESD Protection
For ESD protection of the LCM, here are some recommendations:
1.
RST (Reset pin): Please increase the resistance of this pin. Here is an example:
Reset protection
2.
ESD Protection Ring: “Shielding Ground” is the first protection of ESD. By connecting the “Blue” (ITO) ring to
the FPC, the protection ring is finished.

16.3 SPI (3-Line) ITO Suggestion
In order to get good transfer quality, the SI should have enough ITO width to reduce the ITO resistance (Interface SPI 3
Line). The recommended layout topology is shown below:
