ILI9340
1. Introduction
ILI9340 is a 262,144-color single-chip SOC driver for a-TFT liquid crystal display with resolution of 240RGBx320
dots, comprising a 720-channel source driver, a 320-channel gate driver, 172,800 bytes GRAM for graphic
display data of 240RGBx320 dots, and power supply circuit.
ILI9340 supports parallel 8-/9-/16-/18-bit data bus MCU interface, 8-/16-/18-bit data bus RGB interface and
3-/4-line serial peripheral interface (SPI). The moving picture area can be specified in internal GRAM by window
address function. The specified window area can be updated selectively, so that moving picture can be
displayed simultaneously independent of still picture area.
ILI9340 can operate with 1.65V ~ 3.3V I/O interface voltage and an incorporated voltage follower circuit to
generate voltage levels for driving an LCD. ILI9340 supports full color, 8-color display mode and sleep mode for
precise power control by software and these features make the ILI9340 an ideal LCD driver for medium or small
size portable products such as digital cellular phones, smart phone, MP3 and PMP where long battery life is a
major concern.

7.1.2. 8080-Ⅰ
Ⅰ Series Parallel Interface
ILI9340 can be accessed via 8-/9-/16-/18-bit MCU 8080-
Ⅰ series parallel interface. The chip-select CSX (active
low) is used to enable or disable ILI9340 chip. The RESX (active low) is an external reset signal. WRX is the
parallel data write strobe, RDX is the parallel data read strobe and D[17:0] is parallel data bus.
ILI9340 latches the input data at the rising edge of WRX signal. The D/CX is the signal of data/command
selection. When D/CX=’1’, D [17:0] bits are display RAM data or command’s parameters. When D/CX=’0’, D
[17:0] bits are commands.
Ⅰ series bi-directional interface can be used for communication between the MCU controller and
LCD driver chip. The 8080-Ⅰ Interface selection is done when IM3 pin is low state (VSS level). Interface bus
The 8080-

7.1.3. Write Cycle Sequence
The WRX signal is driven from high to low and then be pulled back to high during the write cycle. The host
processor provides information during the write cycle when the display module captures the information from
host processor on the rising edge of WRX. When the D/CX signal is driven to low level, then input data on the
interface is interpreted as command information. The D/CX signal also can be pulled high level when the data on
the interface is RAM data or command’s parameter.
The following figure shows a write cycle for the 8080-
Ⅰ MCU interface.

7.1.4. Read Cycle Sequence
The RDX signal is driven from high to low and then allowed to be pulled back to high during the read cycle. The
display module provides information to the host processor during the read cycle while the host processor reads
the display module information on the rising edge of RDX signal. When the D/CX signal is driven to low level,
then input data on the interface is interpreted as command. The D/CX signal also can be pulled high level when
the data on the interface is RAM data or command parameter.

7.1.6. Write Cycle Sequence
The WRX signal is driven from high to low and then be pulled back to high during the write cycle. The host
processor provides information during the write cycle when the display module captures the information from
host processor on the rising edge of WRX. When the D/CX signal is driven to low level, then input data on the
interface is interpreted as command information. The D/CX signal also can be pulled high level when the data on
the interface is RAM data or command’s parameter.
The following figure shows a write cycle for the 8080-
Ⅱ MCU interface.

7.1.7. Read Cycle Sequence
The RDX signal is driven from high to low and then allowed to be pulled back to high during the read cycle. The
display module provides information to the host processor during the read cycle while the host processor reads
the display module information on the rising edge of RDX signal. When the D/CX signal is driven to low level,
then input data on the interface is interpreted as command. The D/CX signal also can be pulled high level when
the data on the interface is RAM data or command parameter.

Function
ILI9340 supplies 3-lines/ 9-bit and 4-line/8-bit bi-directional serial interfaces for communication between host
and ILI9340. The 3-line serial mode consists of the chip enable input (CSX), the serial clock input (SCL) and
serial data Input/Output (SDA or SDI/SDO). The 4-line serial mode consists of the Data/Command selection
input (D/CX), chip enable input (CSX), the serial clock input (SCL) and serial data Input/Output (SDA or
SDI/SDO) for data transmission. The data bus (D [17:0]), which are not used, must be connected to GND. Serial
clock (SCL) is used for interface with MCU only, so it can be stopped when no communication is necessary.
7.1.9. Write Cycle Sequence
The write mode of the interface means that host writes commands or data to ILI9340. The 3-lines serial data
packet contains a data/command select bit (D/CX) and a transmission byte. If the D/CX bit is “low”, the
transmission byte is interpreted as a command byte. If the D/CX bit is “high”, the transmission byte is stored as
the display data RAM (Memory write command), or command register as parameter.
Any instruction can be sent in any order to ILI9340 and the MSB is transmitted first. The serial interface is
initialized when CSX is high status. In this state, SCL clock pulse and SDA data are no effect. A falling edge on
CSX enables the serial interface and indicates the start of data transmission. See the detailed data format for
3-/4-line serial interface.

7.1.10. Read Cycle Sequence
The read mode of interface means that the host reads register’s parameter or display data from ILI9340. The
host has to send a command (Read ID or register command) and then the following byte is transmitted in the
opposite direction. ILI9340 latches the SDA (input data) at the rising edges of SCL (serial clock), and then shifts
SDA (output data) at falling edges of SCL (serial clock). After the read status command has been sent, the SDA
line must be set to tri-state and no later than at the falling edge of SCL of the last bit. The read mode has three
types of transmitted command data (8-/24-/32-bit) according command code.

7.1.11. Data Transfer Break and Recovery
If there is a break in data transmission by RESX pulse, while transferring a command or frame memory data or
multiple parameter command data, before Bit D0 of the byte has been completed, then the driver will reject the
previous bits and have reset the interface such that it will be ready to receive command data again when the
chip select pin (CSX) is activated after RESX have been high state.

7.1.12. Data Transfer Pause
It will be possible when transferring a command, frame memory data or multiple parameter data to invoke a
pause in the data transmission. If the chip select pin (CSX) is released to high state after a whole byte of a frame
memory data or multiple parameter data has been completed, then ILI9340 will wait and continue the frame
memory data or parameter data transmission from the point where it was paused. If the chip select pin is
released after a whole byte of a command has been completed, then the display module will receive either the
command’s parameters (if appropriate) or a new command when the chip select pin is next enabled as shown
below.
This applies to the following 4 conditions:
1) Command-Pause-Command
2) Command-Pause-Parameter
3) Parameter-Pause-Command
4) Parameter-Pause-Parameter
Condition 1:
The host transmits a new Command
(Command 2) when a pause occurs
after Command 1.

7.2. RGB Interface
7.2.1. RGB Interface Selection
ILI9340 has two kinds of RGB interface and these interfaces can be selected by RCM [1:0] bits. When RCM [1:0]
bits are set to “10”, the DE mode is selected which utilizes VSYNC, HSYNC, DOTCLK, DE, D [17:0] pins; when
RCM [1:0] bits are set to “11”, the SYNC mode is selected which utilizes which utilizes VSYNC, HSYNC,
DOTCLK, D [17:0] pins. Using RGB interface must selection serial interface.
ILI9340 supports several pixel formats that can be selected by DPI [2:0] bits of “Pixel Format Set (3Ah)” and RIM
bit of RF6h command. The selection of a given interfaces is done by setting RCM [1:0] and DPI [2:0] as show in

clock for other functions of the display module. Vertical synchronization (VSYNC) is used to tell when there is
received a new frame of the display. This is low enable and its state is read to the display module by a rising
edge of the DOTCLK signal.
Horizontal synchronization (HSYNC) is used to tell when there is received a new line of the frame. This is low
enable and its state is read to the display module by a rising edge of the DOTCLK signal.
In DE mode, Data Enable (DE) is used to tell when there is received RGB information that should be transferred
on the display. This is a high enable and its state is read to the display module by a rising edge of the DOTCLK
signal. D [17:0] are used to tell what is the information of the image that is transferred on the display (When
DE= ’0’ (low) and there is a rising edge of DOTCLK). D [17:0] can be ‘0’ (low) or ‘1’ (high). These lines are read
by a rising edge of the DOTCLK signal. In SYNC mode, the valid display data in inputted in pixel unit via D [17:0]
according to HFP/HBP settings of HSYNC signal and VFP/VBP setting of VSYNC. In both RGB interface modes,
the input display data is written to GRAM first then outputs corresponding source voltage according the gray

Typical values are setting example when used with panel resolution 240 x 320 (QVGA), clock frequency 6.35MHz and frame
frequency about 70Hz.
Notes:
1. Vertical period (one frame) shall be equal to the sum of Vsync + VBP + VAdr + VFP.
2. Horizontal period (one line) shall be equal to the sum of Hsync + HBP + HAdr + HFP.
3. Control signals PCLK and Hsync shall be transmitted as specified at all times while valid pixels are transferred
between the host processor and the display module.
Also make sure that
(Number of PCLK per 1 line) ≥ (Number of RTN clock) x Division ratio (DIV) x PCDIV
Setting Example for Display Control Clock in RGB Interface Operation
Register Display operation using DPI is in synchronization with internal clock PCLKD which is generated by dividing
DOTCLK.
PCDIV [5:0]: Number of DOTCLK during internal clock PCLKD’s high / low period. In units of 1 clock.
PCDIV specifying DOTCLK’s division ratio, are determined so that difference between PCLKD’s frequency
and internal oscillation clock 615KHz is the smallest. Set PCDIV follow the restriction
(Number of PCLK in 1H) ≥ (Number of RTN clock) x Division ratio (DIV) x PCDIV.
Setting Example: To set frame frequency to 70Hz:
Internal Clock
Internal Oscillation Clock: 615KHz
DIV[1:0] = 2’b0 (x 1/1)
RTN[4:0] = 5’h1b (27 clocks)
FP = 7'h2 (2 lines), BP = 7'h2 (2 lines), NL = 6’h27 (320 lines)
Frame Rate 70.30Hz
DOTCLK
HSYNC = 10 CLK
HBP = 20 CLK
HFP=10 CLK
70Hz x (2 + 320 + 2) lines x (10 + 20 + 240 + 10) clocks = 6.35MHz
DOTCLK frequency = 6.35MHz
6.35 MHz / 615KHz = 10.32
Set PCDIV so that PCLK is divided by 10.
external fosc = 6.35 MHz / 10 = 635KHz
PCDIV = [ 6.35MHz / 635KHz) / 2 ] - 1 = 4
PCDIV[5:0] = 6’h04 (10 DOTCLK)

7.3. VSYNC Interface
ILI9340 supports the VSYNC interface in synchronization with the frame-synchronizing signal VSYNC to display
the moving picture with the 8080-
Ⅰ/8080-Ⅱ system interface. When the VSYNC interface is selected to display
a moving picture, the minimum GRAM update speed is limited and the VSYNC interface is enabled by setting
DM[1:0] = “10” and RM = “0”.
VSYNC
MPU
nCS

DB[17:0]
In the VSYNC mode, the display operation is synchronized with the internal clock and VSYNC input and the
frame rate is determined by the pulse rate of VSYNC signal. All display data are stored in GRAM to minimize
total data transfer required for moving picture display.

The VSYNC interface has the minimum speed limitation of writing data to the internal GRAM via the system
interface, which are calculated from the following formula.
Internal clock frequency (fosc.) [Hz] = FrameFrequency x (DisplayLine (NL) + FrontPorch (VFP) + BackPorch
(VBP)) x ClockCyclePerLines (RTN) x FrequencyFluctuation.
Minimum RAM write speed [Hz]
＞
240 × DisplayLin es(NL)
[BackPorch (VBP) + DisplayLin es(NL) − margins] × Clocks per line × (1/fosc)
Note: When the RAM write operation does not start from the falling edge of VSYNC, the time from the falling
edge of VSYNC until the start of RAM write operation must also be taken into account.
An example of minimum GRAM writing speed and internal clock frequency in VSYNC interface mode is as
below.
[Example]
Display size: 240 RGB × 320 lines
Lines: 320 lines (NL = 100111)
Back porch: 2 lines (VBP = 0000010)
Front porch: 2 lines (VFP = 0000010)
Frame frequency: 70 Hz
Frequency fluctuation: 10%
Internal oscillator clock (fosc.) [Hz] = 70 x [320+ 2 + 2] x 27 clocks x (1.1/0.9)
≒ 748KHz

ILI9340
When calculate the internal clock frequency, the oscillator variation is needed to be taken into consideration. In
the above example, the calculated internal clock frequency with ±10% margin variation is considered and
ensures to complete the display operation within one VSYNC cycle. The causes of frequency variation come
from fabrication process of LSI, room temperature, external resistors and VCI voltage variation.
Minimum speed for RAM writing [Hz] > 240 x 320 x 748K / [ (2 + 320 – 2)lines x 27clocks]
≒ 6.65 MHz
The above theoretical value is calculated based on the premise that the ILI9340 starts to write data into the
internal GRAM on the falling edge of VSYNC. There must at least be a margin of 2 lines between the physical
display line and the GRAM line address where data writing operation is performed. The GRAM write speed of
6.65MHz or more will guarantee the completion of GRAM write operation before the ILI9340 starts to display the
GRAM data on the screen and enable to rewrite the entire screen without flicker.
Notes in using the VSYNC interface
1. The minimum GRAM write speed must be satisfied and the frequency variation must be taken into
consideration.
2. The display frame rate is determined by the VSYNC signal and the period of VSYNC must be longer than the
scan period of an entire display.
3. When switching from the internal clock operation mode (DM[1:0] = “00”) to the VSYNC interface mode or
inversely, the switching starts from the next VSYNC cycle, i.e. after completing the display of the frame.
4. The partial display, vertical scroll, and interlaced scan functions are not available in VSYNC interface mode.

7.6.7. 6-bit Parallel RGB Interface
The 6-bit RGB interface is selected by setting the DPI [2:0] bit to “110”. When RCM [1:0] are set to “10” and DE
mode is selected, the display operation is synchronized with VSYNC, HSYNC and DOTCLK signals.
The
display data are transferred to the internal GRAM in synchronization with the display operation via 6-bit RGB
data bus (D [5:0]) according to the data enable signal (DE) when RCM [1:0] are set to “10”. The RGB interface
SYNC mode is selected by setting the RCM [1:0] to “11”, the valid display data is inputted in pixel unit via D [5:0]
according to the VFP/VBP and HFP/HBP settings. Unused pins must be connected to GND to ensure normally
operation. Registers can be set by the SPI system interface.

ILI9340 has data transfer counters to count the first, second, third data transfer in 6-bit RGB interface mode. The
transfer counter is always reset to the state of first data transfer on the falling edge of VSYNC. If a mismatch
arises in the number of each data transfer, the counter is reset to the state of first data transfer at the start of the
frame (i.e. on the falling edge of VSYNC) to restart data transfer in the correct order from the next frame. This
function is expedient for moving picture display, which requires consecutive data transfer in light of minimizing
effects from failed data transfer and enabling the system to return to a normal state.
Note that internal display operation is performed in units of pixels (RGB: taking 3 inputs of DOTCLK).
Accordingly, the number of DOTCLK inputs in one frame period must be a multiple of 3 to complete data transfer
correctly. Otherwise it will affect the display of that frame as well as the next frame.

This command transfers image data from the host processor to the display module’s frame memory continuing from the
pixel location following the previous write_memory_continue or write_memory_start command.
If set_address_mode B5 = 0:
Data is written continuing from the pixel location after the write range of the previous write_memory_start or
write_memory_continue. The column register is then incremented and pixels are written to the frame memory until the
column register equals the End Column (EC) value. The column register is then reset to SC and the page register is
incremented. Pixels are written to the frame memory until the page register equals the End Page (EP) value and the
column register equals the EC value, or the host processor sends another command. If the number of pixels exceeds (EC –
SC + 1) * (EP – SP + 1) the extra pixels are ignored.
If set_address_mode B5 = 1:
Data is written continuing from the pixel location after the write range of the previous write_memory_start or
write_memory_continue. The page register is then incremented and pixels are written to the frame memory until the page

This command is used to set the minimum brightness value of the display for CABC function.
CMB[7:0]: CABC minimum brightness control, this parameter is used to avoid too much brightness reduction.
When CABC is active, CABC cannot reduce the display brightness to less than CABC minimum brightness setting. Image
processing function is worked as normal, even if the brightness cannot be changed.
This function does not affect to the other function, manual brightness setting. Manual brightness can be set the display
Description
brightness to less than CABC minimum brightness. Smooth transition and dimming function can be worked as normal.
When display brightness is turned off (BCTRL=0 of “Write CTRL Display (53h)”), CABC minimum brightness setting is
ignored.
In principle relationship is that 00h value means the lowest brightness for CABC and FFh value means the highest
brightness for CABC.

9. Display Data RAM
9.1. Configuration
The display data RAM stores display dots and consists of 1,382,400 bits (240x18x320 bits). There is no
restriction on access to the RAM even when the display data on the same address is loaded to DAC. There will
be no abnormal visible effect on the display when there is a simultaneous panel read and interface read or write
display data to the same location of the frame memory.

10. Tearing Effect Output
The Tearing Effect output line supplies to the MCU a Panel synchronization signal. This signal can be enabled or
disabled by the Tearing Effect Line Off & On commands. The mode of the Tearing Effect Signal is defined by the
parameter of the Tearing Effect Line Off & On commands.
The signal can be used by the MCU to synchronize Frame Memory Writing when displaying video images.
10.1. Tearing Effect Line Modes
Mode 1, the Tearing Effect Output signal consists of V-Sync information only:
tvdl
tvdh
Vertical Time Scale
tvdh = The LCD display is not updated from the Frame Memory.
tvdl = The LCD display is updated from the Frame Memory (except Invisible Line – see below).
Mode 2, the tearing effect output signal consists of V-Sync and H-Sync information; there is one V-sync and 320
H-sync pulses per field:

11. Sleep Out – Command and Self-Diagnostic Functions of the
Display Module
11.1. Register loading Detection
Sleep Out-command (Command “Sleep Out (11h)”) is a trigger for an internal function of the display module,
which indicates, if the display module loading function of factory default values from EV Memory(or similar
device) to registers of the display controller is working properly.
If the register loading detection is successfully, 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 D7). If it is
failure, this bit (D7) is not inverted (= not increased by 1).
The flow chart for this internal function is following:
Power on sequence
HW reset
SW reset
Sleep IN (10h)
Sleep OUT
mode
Sleep IN
mode
RDDSDR(0Fh)'s D7 = '0'
Sleep OUT (11h)
Register Loading Detection
Successful ?
NO
YES

11.2. Functionality Detection
Sleep Out-command (Command “Sleep Out (11h)”) is a trigger for an internal function of the display module,
which indicates, if the display module is still running and meets functionality requirements.
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 an inverted (=
increased by 1) 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 (= increased
by 1). The flow chart for this internal function is shown as below.
The flow chart for this internal function is following:
Power on sequence
HW reset
SW reset
Sleep IN (10h)
Sleep OUT
mode
Sleep IN
mode
RDDSDR(0Fh)'s D6 = '0'
Sleep OUT (11h)
Check timings, valtage levels,
and other functionalities
Is the required
functionality present?
NO
YES
D6 inverted
Note 1: 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 User’s 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.

12. Power ON/OFF Sequence
VDDI and VCI can be applied in any order.
VCI and VDDI can be powered down in any order.
During power off, if LCD is in the Sleep Out mode, VCI and VDDI must be powered down minimum
120msec after RESX has been released.
During power off, if LCD is in the Sleep In mode, VDDI or VCI can be powered down minimum 0msec after
RESX has been released.
CSX can be applied at any timing or can be permanently grounded. RESX has priority over CSX.
Note 1: There will be no damage to the display module if the power sequences are not met.
Note 2: There will be no abnormal visible effects on the display panel during the Power On/Off Sequences.
Note 3: 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.
Note 4: If RESX line is not held stable by host during Power On Sequence as defined in Sections 12.1 and 12.2,
then it will be necessary to apply a Hardware Reset (RESX) after Host Power On Sequence is complete
to ensure correct operation. Otherwise function is not guaranteed.
12.1. Case 1 – RESX line is held High or Unstable by Host at Power ON
If RESX line is held High or unstable by the host during Power On, then a Hardware Reset must be applied after
both VCI and VDDI have been applied – otherwise correct functionality is not guaranteed. There is no timing
restriction upon this hardware reset.

Note 1: Unless otherwise specified, timings herein show cross point at 50% of signal power level.
12.2. Case 2 – RESX line is held Low by Host at Power ON
If RESX line is held Low (and stable) by the host during Power On, then the RESX must be held low for minimum
10µsec after both VCI and VDDI have been applied.
Note 1: Unless otherwise specified, timings herein show cross point at 50% of signal power level.

12.3. 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 event, ILI9340 will force the display to
blank and will not be any abnormal visible effects with in 1 second on the display and remains blank until “Power
On Sequence” actives.

13. Power Level Definition
13.1. 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 262,144 colors.
2. Partial Mode On, Idle Mode Off, Sleep Out.
In this mode part of the display is used with maximum 262,144 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 VDDI power supply. Contents of the memory are safe.
6. Power Off Mode.
In this mode, both VCI and VDDI are removed.
Note1: Transition between modes 1-5 is controllable by MCU commands. Mode 6 is entered only when both
Power supplies are removed.

Note 1: The reset cancel includes also required time for loading ID bytes, VCOM setting and other settings from
NV memory to registers. This loading is done every time when there is HW reset cancel time (tRT)
within 5 ms after a rising edge of RESX.
Note 2: Spike due to an electrostatic discharge on RESX line does not cause irregular system reset according to
the table below: -
RESX Pulse

Shorter than 5us
Reset Rejected
Longer than 10us

Between 5us and 10us

Note 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.
Note 4: Spike Rejection also applies during a valid reset pulse as shown below:
Note 5: When Reset applied during Sleep In Mode.
Note 6: When Reset applied during Sleep Out Mode.
Note 7: It is necessary to wait 5msec after releasing RESX before sending commands. Also Sleep Out
command cannot be sent for 120msec.

VCOML (VCL+0.5) ~ -1V )
BT
VCL
VCL (-2.0 ~ -3.0V)
VGL
VGL (-5.0 ~ -15.0V)
Note: The AVDD, VGH, VGL, and VCL output voltage levels are lower than their theoretical levels (ideal voltage
levels) due to current consumption at respective outputs. The voltage levels in the following relationships
(AVDD – GVDD ) > 0.2V and (VCOML – VCL) > 0.5V are the actual voltage levels. When the alternating cycles
of VCOM are set high (e.g. the polarity inverts every line cycle), current consumption is large. In this case, check
the voltage before use.
