ILI9328
1. Introduction
ILI9328 is a 262,144-color one-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 RAM for graphic data
of 240RGBx320 dots, and power supply circuit.
ILI9328 has four kinds of system interfaces which are i80-system MPU interface (8-/9-/16-/18-bit bus width),
VSYNC interface (system interface + VSYNC, internal clock, DB[17:0]), serial data transfer interface (SPI)
and RGB 6-/16-/18-bit interface (DOTCLK, VSYNC, HSYNC, ENABLE, DB[17:0]).
In RGB interface and VSYNC interface mode, the combined use of high-speed RAM write function and widow
address function enables to display a moving picture at a position specified by a user and still pictures in other
areas on the screen simultaneously, which makes it possible to transfer display the refresh data only to
minimize data transfers and power consumption.
ILI9328 can operate with 1.65V I/O interface voltage, and an incorporated voltage follower circuit to generate
voltage levels for driving an LCD. The ILI9328 also supports a function to display in 8 colors and a sleep mode,
allowing for precise power control by software and these features make the ILI9328 an ideal LCD driver for
medium or small size portable products such as digital cellular phones, smart phone, PDA and PMP where
long battery life is a major concern.

ILI9328
5. Block Description
MPU System Interface
ILI9328 supports three system high-speed interfaces: i80-system high-speed interfaces to 8-, 9-, 16-, 18-bit
parallel ports and serial peripheral interface (SPI). The interface mode is selected by setting the IM[3:0] pins.
ILI9328 has a 16-bit index register (IR), an 18-bit write-data register (WDR), and an 18-bit read-data register
(RDR). The IR is the register to store index information from control registers and the internal GRAM. The
WDR is the register to temporarily store data to be written to control registers and the internal GRAM. The
RDR is the register to temporarily store data read from the GRAM. Data from the MPU to be written to the
internal GRAM are first written to the WDR and then automatically written to the internal GRAM in internal
operation. Data are read via the RDR from the internal GRAM. Therefore, invalid data are read out to the data
bus when the ILI9328 read the first data from the internal GRAM. Valid data are read out after the ILI9328
performs the second read operation.
Registers are written consecutively as the register execution time.

Parallel RGB Interface
ILI9328 supports the RGB interface and the VSYNC interface as the external interface for displaying a moving
picture. When the RGB interface is selected, display operations are synchronized with externally supplied
signals, VSYNC, HSYNC, and DOTCLK. In RGB interface mode, data (DB17-0) are written in synchronization
with these signals according to the polarity of enable signal (ENABLE) to prevent flicker on display while
updating display data.
In VSYNC interface mode, the display operation is synchronized with the internal clock except frame
synchronization, where the operation is synchronized with the VSYNC signal. Display data are written to the
internal GRAM via the system interface. In this case, there are constraints in speed and method in writing data
to the internal RAM. For details, see the “External Display Interface” section. The ILI9328 allows for switching
between the external display interface and the system interface by instruction so that the optimum interface is
selected for the kind of picture to be displayed on the screen (still and/or moving picture(s)). The RGB

ILI9328
interface, by writing all display data to the internal RAM, allows for transferring data only when updating the
frames of a moving picture, contributing to low power requirement for moving picture display.
Address Counter (AC)
The address counter (AC) gives an address to the internal GRAM. When the index of the register for setting a
RAM address in the AC is written to the IR, the address information is sent from the IR to the AC. As writing
data to the internal GRAM, the address in the AC is automatically updated plus or minus 1. The window
address function enables writing data only in the rectangular area arbitrarily set by users on the GRAM.
Graphics RAM (GRAM)
GRAM is graphics RAM storing bit-pattern data of 172,820 (240 x 320x 18/8) bytes with 18 bits per pixel.
Grayscale Voltage Generating Circuit
The grayscale voltage generating circuit generates a liquid crystal drive voltage according to grayscale data
set in the γ-correction register to display in 262,144 colors. For details, see the “γ-Correction Register”
section.
Timing Controller
The timing generator generates a timing signal for operation of internal circuits such as the internal GRAM.
The timing for the display operation such as RAM read operation and the timing for the internal operation such
as access from the MPU are generated in the way not to interfere each other.
Oscillator (OSC)
ILI9328 generates RC oscillation with an internal oscillation resistor. The frame rate is adjusted by the register
setting.
LCD Driver Circuit
The LCD driver circuit of ILI9328 consists of a 720-output source driver (S1 ~ S720) and a 320-output gate
th
driver (G1~G320). Display pattern data are latched when the 720 bit data are input. The latched data control
the source driver and generate a drive waveform. The gate driver for scanning gate lines outputs either VGH
or VGL level. The shift direction of 720 source outputs from the source driver is set with the SS bit and the
shift direction of gate outputs from the gate driver is set with the GS bit. The scan mode by the gate driver is
set with the SM bit. These bits allow setting an appropriate scan method for an LCD module.
LCD Driver Power Supply Circuit
The LCD drive power supply circuit generates the voltage levels VREG1OUT, VGH, VGL and Vcom for
driving an LCD.

6. System Interface
6.1. Interface Specifications
ILI9328 has the system interface to read/write the control registers and display graphics memory (GRAM),
and the RGB Input Interface for displaying a moving picture. User can select an optimum interface to display
the moving or still picture with efficient data transfer. All display data are stored in the GRAM to reduce the
data transfer efforts and only the updating data is necessary to be transferred. User can only update a
sub-range of GRAM by using the window address function.
ILI9328 also has the RGB interface and VSYNC interface to transfer the display data without flicker the
moving picture on the screen. In RGB interface mode, the display data is written into the GRAM through the
control signals of ENABLE, VSYNC, HSYNC, DOTCLK and data bus DB[17:0].
In VSYNC interface mode, the internal display timing is synchronized with the frame synchronization signal
(VSYNC). The VSYNC interface mode enables to display the moving picture display through the system
interface. In this case, there are some constraints of speed and method to write data to the internal RAM.
ILI9328 operates in one of the following 4 modes. The display mode can be switched by the control register.
When switching from one mode to another, refer to the sequences mentioned in the sections of RGB and
VSYNC interfaces.

Data transfer synchronization in 8/9-bit bus interface mode
ILI9328 supports a data transfer synchronization function to reset upper and lower counters which count the
transfers numbers of upper and lower byte in 8/9-bit interface mode. If a mismatch arises in the numbers of
transfers between the upper and lower byte counters due to noise and so on, the “00”h register is written 4
times consecutively to reset the upper and lower counters so that data transfer will restart with a transfer of
upper byte. This synchronization function can effectively prevent display error if the upper/lower counters are
periodically reset.

(nCS), the serial transfer clock pin (SCL), the serial data input pin (SDI) and the serial data output pin (SDO)
are used in SPI mode. The ID pin sets the least significant bit of the identification code. The DB[17:0] pins,
which are not used, must be tied to GND.
The SPI interface operation enables from the falling edge of nCS and ends of data transfer on the rising edge
of nCS. The start byte is transferred to start the SPI interface and the read/write operation and RS information
are also included in the start byte. When the start byte is matched, the subsequent data is received by
ILI9328.
The seventh bit of start byte is RS bit. When RS = “0”, either index write operation or status read operation is
executed. When RS = “1”, either register write operation or RAM read/write operation is executed. The eighth
bit of the start byte is used to select either read or write operation (R/W bit). Data is written when the R/W bit is
“0” and read back when the R/W bit is “1”.
After receiving the start byte, ILI9328 starts to transfer or receive the data in unit of byte and the data transfer
starts from the MSB bit. All the registers of the ILI9328 are 16-bit format and receive the first and the second
byte datat as the upper and the lower eight bits of the 16-bit register respectively. In SPI mode, 5 bytes
th
dummy read is necessary and the valid data starts from 6 byte of read back data.

ILI9328 supports the VSYNC interface in synchronization with the frame-synchronizing signal VSYNC to
display the moving picture with the i80 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”.

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

Figure12 Operation through VSYNC Interface
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 (FP) + BackPorch
(BP)) x ClockCyclePerLines (RTN) x FrequencyFluctuation.
240 x DisplayLines (NL)
Minimum RAM write speed (HZ)
[(BackPorch(BP)+DisplayLines(NL) - margins] x 16 (clocks) x 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: 14 lines (BP = 1110)
Front porch: 2 lines (FP = 0010)
Frame frequency: 60 Hz
Frequency fluctuation: 10%

Internal oscillator clock (fosc.) [Hz] = 60 x [320+ 2 + 14] x 16 clocks x (1.1/0.9)
ILI9328
≒
394KHz
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 394K / [ (14 + 320 – 2)lines x 16clocks]
≒
5.7 MHz
The above theoretical value is calculated based on the premise that the ILI9328 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
5.7MHz or more will guarantee the completion of GRAM write operation before the ILI9328 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
and set the AM bit to “0” to transfer display data.

6.5.1. RGB Interface
The display operation via the RGB interface is synchronized with the VSYNC, HSYNC, and DOTCLK signals.
The RGB interface transfers the updated data to GRAM with the high-speed write function and the update
area is defined by the window address function. The back porch and front porch are used to set the RGB
interface timing.

6.5.3. Moving Picture Mode
ILI9328 has the RGB interface to display moving picture and incorporates GRAM to store display data, which
has following merits in displaying a moving picture.
• The window address function defined the update area of GRAM.
• Only the moving picture area of GRAM is updated.
• When display the moving picture in RGB interface mode, the DB[17:0] can be switched as system
interface to update still picture area and registers, such as icons.
RAM access via a system interface in RGB-I/F mode
ILI9328 allows GRAM access via the system interface in RGB interface mode. In RGB interface mode, data
are written to the internal GRAM in synchronization with DOTCLK and ENABLE signals. When write data to
the internal GRAM by the system interface, set ENABLE to terminate the RGB interface and switch to the
system interface to update the registers (RM = “0”) and the still picture of GRAM. When restart RAM access in
RGB interface mode, wait one read/write cycle and then set RM = “1” and the index register to R22h to start
accessing RAM via the RGB interface. If RAM accesses via two interfaces conflicts, there is no guarantee that
data are written to the internal GRAM.
The following figure illustrates the operation of the ILI9328 when displaying a moving picture via the RGB
interface and rewriting the still picture RAM area via the system interface.

6.5.4. 6-bit RGB Interface
The 6-bit RGB interface is selected by setting the RIM[1:0] bits to “10”. The display operation is synchronized
with VSYNC, HSYNC, and DOTCLK signals. Display data are transferred to the internal GRAM in
synchronization with the display operation via 6-bit RGB data bus (DB[17:12]) according to the data enable
signal (ENABLE). Unused pins (DB[11:0]) must be fixed at GND level. Registers can be set by the system
interface (i80/SPI).

Data transfer synchronization in 6-bit RGB interface mode
ILI9328 has data transfer counters to count the first, second, third data transfers 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.

RGB interface mode.
4. In 6-bit RGB interface mode, each of RGB dots is transferred in synchronization with a DOTCLK input. In
other words, it takes 3 DOTCLK inputs to transfer one pixel. Be sure to complete data transfer in units of 3
DOTCLK inputs in 6-bit RGB interface mode.
5. In 6-bit RGB interface mode, data of one pixel, which consists of RGB dots, are transferred in units of
3 DOTCLK. Accordingly, set the cycle of each signal in 6-bit interface mode (VSYNC, HSYNC, ENABLE,
DB[17:0]) to contain DOTCLK inputs of a multiple of 3 to complete data transfer in units of pixels.
6. When switching from the internal operation mode to the RGB Input Interface mode, or the other way around,
follow the sequence below.
7. In RGB interface mode, the front porch period continues until the next VSYNC input is detected after
drawing one frame.
8. In RGB interface mode, a RAM address (AD[15:0]) is set in the address counter every frame on the falling

7. Register Descriptions
7.1. Registers Access
ILI9328 adopts 18-bit bus interface architecture for high-performance microprocessor. All the functional
blocks of ILI9328 starts to work after receiving the correct instruction from the external microprocessor by the
18-, 16-, 9-, 8-bit interface. The index register (IR) stores the register address to which the instructions and
display data will be written. The register selection signal (RS), the read/write signals (nRD/nWR) and data
bus D17-0 are used to read/write the instructions and data of ILI9328. The registers of the ILI9328 are
categorized into the following groups.
1. Specify the index of register (IR)
2. Read a status
3. Display control
4. Power management Control
5. Graphics data processing
6. Set internal GRAM address (AC)
7. Transfer data to/from the internal GRAM (R22)
8. Internal grayscale γ-correction (R30 ~ R39)
Normally, the display data (GRAM) is most often updated, and in order since the ILI9328 can update internal
GRAM address automatically as it writes data to the internal GRAM and minimize data transfer by using the
window address function, there are fewer loads on the program in the microprocessor. As the following figure
shows, the way of assigning data to the 16 register bits (D[15:0]) varies for each interface. Send registers in
accordance with the following data transfer format.

SS: Select the shift direction of outputs from the source driver.
When SS = 0, the shift direction of outputs is from S1 to S720
When SS = 1, the shift direction of outputs is from S720 to S1.
In addition to the shift direction, the settings for both SS and BGR bits are required to change the
assignment of R, G, B dots to the source driver pins.
To assign R, G, B dots to the source driver pins from S1 to S720, set SS = 0.
To assign R, G, B dots to the source driver pins from S720 to S1, set SS = 1.
When changing SS or BGR bits, RAM data must be rewritten.
SM: Sets the gate driver pin arrangement in combination with the GS bit (R60h) to select the optimal scan
mode for the module.

AM Control the GRAM update direction.
When AM = “0”, the address is updated in horizontal writing direction.
When AM = “1”, the address is updated in vertical writing direction.
When a window area is set by registers R50h ~R53h, only the addressed GRAM area is updated based
on I/D[1:0] and AM bits setting.
I/D[1:0] Control the address counter (AC) to automatically increase or decrease by 1 when update one pixel
display data. Refer to the following figure for the details.
I/D[1:0] = 00
I/D[1:0] = 01
I/D[1:0] = 10

Figure25 GRAM Access Direction Setting
ORG
Moves the origin address according to the ID setting when a window address area is made. This
function is enabled when writing data with the window address area using high-speed RAM write.
ORG = “0”: The origin address is not moved. In this case, specify the address to start write operation
according to the GRAM address map within the window address area.
ORG = “1”: The original address “00000h” moves according to the I/D[1:0] setting.
Notes: 1. When ORG=1, only the origin address address”00000h” can be set in the RAM address set
registers R20h, and R21h.
2. In RAM read operation, make sure to set ORG=0.
BGR Swap the R and B order of written data.
BGR=”0”: Follow the RGB order to write the pixel data.

BGR=”1”: Swap the RGB data to BGR in writing into GRAM.
TRI When TRI = “1”, data are transferred to the internal RAM in 8-bit x 3 transfers mode via the 8-bit interface.
It is also possible to send data via the 16-bit interface or SPI in the transfer mode that realizes display in 262k
colors in combination with DFM bits. When not using these interface modes, be sure to set TRI = “0”.
DFM Set the mode of transferring data to the internal RAM when TRI = “1”. See the following figures for
details.

RSZ[1:0] Sets the resizing factor.
When the RSZ bits are set for resizing, the ILI9328 writes the data according to the resizing factor
so that the original image is displayed in horizontal and vertical dimensions, which are contracted
according to the factor respectively. See “Resizing function”.
RCH[1:0] Sets the number of remainder pixels in horizontal direction when resizing a picture.
By specifying the number of remainder pixels by RCH bits, the data can be transferred without
taking the reminder pixels into consideration. Make sure that RCH = 2’h0 when not using the
resizing function (RSZ = 2’h0) or there are no remainder pixels.
RCV[1:0] Sets the number of remainder pixels in vertical direction when resizing a picture.
By specifying the number of remainder pixels by RCV bits, the data can be transferred without
taking the reminder pixels into consideration. Make sure that RCV = 2’h0 when not using the

D[1:0] Set D[1:0]=”11” to turn on the display panel, and D[1:0]=”00” to turn off the display panel.
A graphics display is turned on the panel when writing D1 = “1”, and is turned off when writing
D1 = “0”.
When writing D1 = “0”, the graphics display data is retained in the internal GRAM and the
ILI9328 displays the data when writing D1 = “1”. When D1 = “0”, i.e. while no display is shown on the
panel, all source outputs becomes the GND level to reduce charging/discharging current, which is
generated within the LCD while driving liquid crystal with AC voltage.
When the display is turned off by setting D[1:0] = “01”, the ILI9328 continues internal display
operation. When the display is turned off by setting D[1:0] = “00”, the ILI9328 internal display
operation is halted completely. In combination with the GON, DTE setting, the D[1:0] setting controls
display ON/OFF.

HSA[7:0]/HEA[7:0] HSA[7:0] and HEA[7:0] represent the respective addresses at the start and end of the
window address area in horizontal direction. By setting HSA and HEA bits, it is possible to limit the
area on the GRAM horizontally for writing data. The HSA and HEA bits must be set before starting
RAM write operation. In setting these bits, be sure “00”h ≤ HSA[7:0]< HEA[7:0] ≤ “EF”h. and
“04”h≦HEA-HAS.
VSA[8:0]/VEA[8:0] VSA[8:0] and VEA[8:0] represent the respective addresses at the start and end of the
window address area in vertical direction. By setting VSA and VEA bits, it is possible to limit the
area on the GRAM vertically for writing data. The VSA and VEA bits must be set before starting
RAM write operation. In setting, be sure “000”h ≤ VSA[8:0]< VEA[8:0] ≤ “13F”h.

9. Window Address Function
The window address function enables writing display data consecutively in a rectangular area (a window
address area) made on the internal RAM. The window address area is made by setting the horizontal address
register (start: HSA[7:0], end: HEA[7:0] bits) and the vertical address register (start: VSA[8:0], end: VEA[8:0]
bits). The AM bit sets the transition direction of RAM address (either increment or decrement). These bits
enable the ILI9328 to write data including image data consecutively not taking data wrap positions into
account.
The window address area must be made within the GRAM address map area. Also, the GRAM address bits
(RAM address set register) must be an address within the window address area.
[Window address setting area]
(Horizontal direction) 00H ≤ HSA[7:0] ≤ HEA[7:0] ≤ “EF”H
(Vertical direction) 00H ≤ VSA[8:0] ≤ VEA[8:0]≤ “13F”H

1. Gradient adjustment registers
The gradient adjustment registers are used to adjust the gradient of the curve representing the relationship
between the grayscale and the grayscale reference voltage level. To adjust the gradient, the resistance
values of variable resistors in the middle of the ladder resistor are adjusted by registers PRP0[2:0]/PRN0[2:0],
PRP1[2:0]/PRN1[2:0]. The registers consist of positive and negative polarity registers, allowing asymmetric
drive.
2. Amplitude adjustment registers
The amplitude adjustment registers, VRP0[3:0]/VRN0[3:0], VRP1[4:0]/VRN1[4:0], are used to adjust the
amplitude of grayscale voltages. To adjust the amplitude, the resistance values of variable resistors at the top
and bottom of the ladder resistor are adjusted. Same as the gradient registers, the amplitude adjustment
registers consist of positive and negative polarity registers.
3. Fine adjustment registers
The fine adjustment registers are used to fine-adjust grayscale voltage levels. To fine-adjust grayscale
voltage levels, fine adjustment registers adjust the reference voltage levels, 8 levels for each register
generated from the ladder resistor, in respective 8-to-1 selectors. Same with other registers, the fine
adjustment registers consist of positive and negative polarity registers.

Ladder resistors and 8-to-1 selector Block configuration
The reference voltage generating block consists of two ladder resistor units including variable resistors and
8-to-1 selectors. Each 8-to-1 selector selects one of the 8 voltage levels generated from the ladder resistor
unit to output as a grayscale reference voltage. Both variable resistors and 8-to-1 selectors are controlled
according to the γ-correction registers. This unit has pins to connect a volume resistor externally to
compensate differences in various characteristics of panels.
Variable resistors
ILI9328 uses variable resistors of the following three purposes: gradient adjustment (VRCP(N)0/VRCP(N)1);
amplitude adjustment (1) (VROP(N)0); and the amplitude adjustment (2) (VROP(N)1). The resistance values
of these variable resistors are set by gradient adjustment registers and amplitude adjustment registers as
follows.

11.5. Voltage Generation
The pattern diagram for setting the voltages and the waveforms of the voltages of the ILI9328 are as follows.
VGH (+9 ~ 16.5V)
VLCD (4.5 ~ 5.5V)
VREG1OUT (3.0 ~ (VLCD-0.2)V )
VCOMH (3.0 ~ (VLCD-0.2)V )
Vci
(2.5 ~ 3.3V)
VCOML (VCL+0.5) ~ -1V )
VCL (0 ~ -3.3V)
VGL (-4.0 ~ -16.5V)
Figure 45 Voltage Configuration Diagram
Note: The DDVDH, 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 (DDVDH – VREG1OUT ) > 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.

11.8. Resizing Function
ILI9328 supports resizing function (x1/2, x1/4), which is performed when writing image data to GRAM. The
resizing function is enabled by setting a window address area and the RSZ bit which represents the resizing
factor (x1/2, x1/4) of image. The resizing function allows the system to transfer the original-size image data
into the GRAM with resized image data.
