R61509V Target Spec
Block Function
1. System Interface
The R61509V supports 80-system high-speed interface via 8-, 9-, 16-, 18-bit parallel ports and a clock
synchronous serial interface. The interface is selected by setting the IM2-0 pins.
The R61509V has 16-bit index register (IR), 18-bit write-data register (WDR), and 18-bit read-data register
(RDR). The IR is the register to store index information from control register and internal GRAM. The
WDR is the register to temporarily store write data to control register and internal GRAM. The RDR is the
register to temporarily store the read data from the GRAM. The write data from the host processor to the
internal GRAM is first written to the WDR and then automatically written to the internal GRAM by
internal operation. The data is read via RDR from the internal GRAM. Therefore, invalid data is sent to
the data bus when the R61509V performs the first read operation from the internal GRAM. Valid data is
read out when the R61509V performs the second and subsequent read operation.
The R61509V allows writing instructions consecutively by executing the instruction in the same cycle
when it is written (0 instruction cycle).
The R61509V supports RGB and VSYNC interfaces as the external interface to display moving picture.
When the RGB interface is selected, the display operation is synchronized with externally supplied
synchronous signals (VSYNCX, HSYNCX, and DOTCLK). In RGB interface operation, data (DB17-0) is
written in synchronization with these signals when the polarity of enable signal (ENABLE) allows write
operation in order to prevent flicker when updating display data.
In VSYNC interface operation, the display operation is synchronized with the internal clock except frame
synchronization, which synchronizes the display operation with the VSYNCX signal. The display data is
written to the internal GRAM via system interface. When writing data via VSYNC interface, there are
constraints in speed and method in writing data to the internal RAM. For details, see Section “VSYNC
Interface”.
The R61509V allows switching interface by instruction according to the display image (still and/or moving
picture). This allows data to be transferred only when the data is updated hence less power consumption
during moving picture display.
3. Address Counter (AC)
The address counter (AC) gives an address to the internal GRAM. When the index of a register is written
to the IR, the address information is sent from the IR to the AC. After data is written to GRAM, the
address in the AC is automatically updated plus or minus 1. The window address function enables writing
data only within the rectangular area specified in the GRAM.
Rev. 0.11 April 25, 2008, page 12 of 181
R61509V Target Spec
4. Graphics RAM (GRAM)
GRAM stands for graphics RAM, which can store bit-pattern data of 233,280 (240RGB x 432 (dots) x
18(bits)) bytes at maximum, using 18 bits per pixel.
5. Grayscale Voltage Generating Circuit
The grayscale voltage generating circuit generates liquid crystal drive voltages according to the grayscale
data in the γ-correction registers to enable 262k-color display. For details, see the γ-Correction Register
section.
6. Liquid Crystal Drive Power Supply Circuit
The liquid crystal drive power supply circuit generates DDVDH, VGH, VGL and VCOM levels to drive
liquid crystal.
7. Timing Generator
The timing generator generates a timing signal for the operation of internal circuits such as the internal
GRAM. The timing signal for display operations such as RAM read and the timing signal for internal
operations such as RAM access from the host processor are generated separately in order to avoid mutual
interference.
8. Oscillator (OSC)
The R61509V generates the RC oscillation clock internally. Using an external oscillation resistor is not
possible. The oscillation frequency is set to 678 kHz before shipment (for details, see Electrical
Characteristics). Use the frame frequency adjustment function to change the number of display lines and
the frame frequency. While the R61509V is shut down, RC oscillation halts so that reduce power
consumption is reduced.
9. Liquid crystal driver Circuit
The liquid crystal driver circuit of the R61509V consists of a 720-output source driver (S1 ~ S720) and a
432-output gate driver (G1~G432). The display pattern data is latched when all of 240RGB data are
inputted. The latched data control the source driver and output drive waveforms. The gate driver for
scanning gate lines outputs either VGH or VGL level. The shift direction of 720-bit source output from the
source driver can be changed by setting the SS bit and the shift direction of gate output from the gate driver
can be changed by setting the GS bit. The scan mode by the gate driver can be changed by setting the SM
bit.
10. Internal Logic Power Supply Regulator
The internal logic power supply regulator generates internal logic power supply VDD.

R61509V Target Spec
GRAM Address Map
Table 11 GRAM address and display position on the panel (SS = 0, BGR = 0)
The R61509V adopts 18-bit bus architecture in order to interface to high-performance microcomputer in
high speed. The R61509V starts internal processing after storing control information (18, 16, 9, 8, 1 bit(s)),
sent from the microcomputer, in the instruction register (IR) and the data register (DR). Since the internal
operation of the R61509V is controlled by the signals sent from the microcomputer, the register selection
signal (RS), the read/write signal (R/W), and the internal 16-bit data bus signals (IB15 ~ IB0) are called
instructions. The following are the kinds of instruction of the R61509V.
1. Specify index
2. Display control
3. Power management control
4. Set internal GRAM addresssss
5. Transfer data to and from the internal GRAM
6. Window address control
7. γ-correction
8. Panel Display Control
Normally, the data write instructions (5) are used the most frequently. The internal GRAM address is
updated automatically as data is written to the internal GRAM, which, in combination with the window
address function, contributes to minimizing data transfer and thereby lessens the load on the microcomputer.
The R61509V writes instructions consecutively by executing the instruction within the cycle when it is
written (instruction execution time: 0 cycle).
Instruction Data Format
As the following figure shows, the data bus used to transfer 16 instruction bits (IB[15:0]) is different
according to the data format of a selected interface. Make sure to transfer the instruction bits according to
the format of the selected interface.
The bits to which no instruction is assigned must be set to either “0” or “1” according to the following
register tables. When changing only one instruction bit setting, the setting values in other bits in the
register must be written.
The index register specifies the indexes of control register or RAM control to be accessed. It is prohibited
to access registers and instruction bits to which no index register is assigned.
SS: Sets the shift direction of output from the source driver.
When SS = “0”, the source driver output shift from S1 to S720.
When SS = “1”, the source driver output shift from S720 to S1.
The combination of SS and BGR settings determines the RGB assignment to the source driver pins S1 ~
S720.
When SS = “0” and BGR = “0”, RGB dots are assigned one to one from S1 to S720.
When SS = “1” and BGR = “1”, RGB dots are assigned one to one from S720 to S1.
When changing the SS and BGR bits, RAM data must be rewritten.
SM: Controls the scan mode in combination with GS setting. See “ Scan mode setting”.
The entry mode registers include instruction bits for setting how to write data from the microcomputer to
the internal GRAM of the R61509V.
AM: Sets either horizontal or vertical direction in updating the address counter automatically as the
R61509V writes data to the internal GRAM.
AM = “0”, sets the horizontal direction.
AM = “1”, sets the vertical direction.
When specifying window address area, the data is written only within the area in the direction determined
by ID and AM bits.
ID[1:0]: Either increments (+1) or decrements (-1) the address counter (AC) automatically as the data is
written to the GRAM. The ID[0] bit sets either increment or decrement in horizontal direction (updates the
address AD[7:0]). The ID[1] bit sets either increment or decrement in vertical direction (updates the
address AD[8:16]). The AM bit sets either horizontal or vertical direction in updating RAM address
counter automatically when writing data to the internal RAM.
ORG: Moves the origin address according to the ID setting when a window address area is described. This
function is enabled when executing burst data transfer within the window address area.
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 origin address “h00000” is moved according to the ID[1:0] setting.
Notes: 1. When ORG = 1, the origin address can be set only at “h00000”.
2. In RAM read operation, make sure to set ORG = 0.

R61509V Target Spec
BGR: Reverses the order from RGB to BGR in writing 18-bit pixel data in the GRAM.
BGR = 0: Write data in the order of RGB to the GRAM.
BGR = 1: Reverse the order from RGB to BGR in writing data to the GRAM.
DFM: In combination with the TRI setting, DFM sets the format to develop 16-/8-bit data to 18-bit data
when using either 16- or 8-bit bus interface. Make sure to set DFM = 0 when not transferring data via 16bit or 8-bit interface. Set DFM in accordance with selected interface and image data format in RAM write
operation.
DFM=0: 18bpp (R:G:B = 6:6:6), DFM=1: 16bpp (R:G:B = 5:6:5)
TRI: Selects the format to transfer data bits via 16-bit or 8-bit interface.
In 8-bit interface operation,
TRI = 0: 16-bit RAM data is transferred in two transfers.
TRI = 1: 18-bit RAM data is transferred in three transfers.
In 16-bit bus interface operation,
TRI = 0: 16-bit RAM data is transferred in one transfer.
TRI = 1: 18-bit RAM data is transferred in two transfers.
Make sure TRI = 0 when not transferring data via 16- or 8-bit interface. Also, set TRI = 0 during read
operation.
FP[7:0]: Sets the number of lines for front porch period (a blank period made after the end of display).
BP[7:0]: Sets the number of lines for back porch period (a blank period made before the beginning of
display).
In external display interface operation, a back porch (BP) period starts on the falling edge of the VSYNCX
signal and the display operation starts after the back porch period. After the front porch period, a blank
period continues until next VSYNCX input is detected.

■DC0x Value and DCDC1 Step-up Clock Signal Waveform Example
DCDC1 performs charge operation and boost operation with the step-up clock generated from the timing generator.
The DCDC1 step-up clock frequency is adjusted by setting the division ratio of the reference clock frequency with DC0x register.
(To prevent flickering, the DCDC1 step-up clock signal is synchronized with the reference point of display operation in unit of lines.)
Note: Set DC0x and RTNx so that (DCDC1 step-up clock frequency) ≧ (line clock frequency)
If the above restrictio n is not fol lowed, the duty cycle during the boost period is less than 50%. As a result, the step-up circuit may not operate normally.

■DC1x Value and DCDC2 Step-up Clock Signal Waveform Example
DCDC2 performs charge operation and boost operation with the step-up clock generated from the timing generator.
The DCDC2 step-up clock frequency is adjusted by setting the division ratio of the reference clock frequency with DC1x register.
(To prevent flicker, the DCDC2 step-up clock signal is synchronized with the head of BP period in unit of lines.)
Example) BP=FP=8'h08, NL=7'h6B (front porch = back porch 8 lines, the number of lines to drive the LCD = 432 lines)

AD[16:0]: Sets a GRAM address in the AC (Address Counter) which is automatically updated according to
the combination of AM, ID[1:0] settings as the R61509V writes data to the internal GRAM. Data can be
written consecutively without resetting the address in the AC. The address is not automatically updated
after reading data from the internal GRAM.
Note 1: In RGB interface operation (RM = “1”), the address AD16-0 is set in the address counter every
frame on the falling edge of VSYNCX.
Note 2: In internal clock operation and VSYNC interface operation (RM = “0”), the address AD16-0 is set
when executing the instruction.

RAM write data WD[17:0] is transferred via different data bus in different interface operation.
data into 18 bits is different in different interface operation.
The GRAM data represents the grayscale level. The R61509V automatically updates the address according
to AM and ID[1:0] settings as it writes data in the GRAM. The DFM bit sets the format to develop 16-bit
data into the 18-bit data in 16-bit or 8-bit interface operation.
Note: When writing data in the GRAM via system interface while using the RGB interface, make sure
that write operations via two interfaces that do not conflict one another.

RD[17:0]: 18-bit data read from the GRAM. RAM read data RD[17:0] is transferred via different data bus
in different interface operation.
When the R61509V reads data from the GRAM to the microcomputer, the first word read immediately
after RAM address set is not outputted. Therefore, data on the data bus is invalid. Valid data is sent to the
data bus when the R61509V reads out the second and subsequent words.
When either 8-bit or 16-bit interface is selected, the LSBs of R and B dot data are not read out.

UID[3:0]: Used to temporarily store NVM data such as used identification code.
The write data is loaded to NVM data write register (NVDAT [7:0]) and then is written to NVM.
NVM data is loaded to UID[7:0] when power on reset, when shutdown mode is exited or when CALB=1 is
written. When NVM data write is not executed, UID[7:0] = 8’hFF (Default).
VCM[6:0]: Used to control VCOMH.
To use NVM data to adjust VCOMH, specify the VCOMH level using VCM [6:0], write the same value to
the NVM data write register NVDAT [14:8] (R6F1h) and then write the data to NVM.
NVM data is loaded to VCM[6:0] when power on reset, when shutdown mode is exited or when CALB=1

R61509V Target Spec
Reset Function
The R61509V is initialized by the RESETX input. During reset period, the R61509V is in a busy state and
instruction from the microcomputer and GRAM access are not accepted. The R61509V’s internal power
supply circuit unit is initialized also by the RESETX input. The RESET period must be secured for at least
1ms. In case of power-on reset, wait until the RC oscillation frequency stabilizes (for 1 ms). During this
period, GRAM access and initial instruction setting are prohibited.
1. Initial state of instruction bits (default)
See the instruction list. The default value is shown in the parenthesis of each instruction bit cell.
2. RAM Data initialization
The RAM data is not automatically initialized by the RESETX input. It must be initialized by software in
display-off period (D1-0 = “00”).

R61509V Target Spec
5 When a RESETX input is entered into the R61509V while it is in shutdown mode, the R61509V starts
up the inside logic regulator and makes a transition to the initial state. During this period, the state of the
interface pins may become unstable. For this reason, do not enter a RESETX input in shutdown mode.
6 When transferring instruction in either two or three transfers via 8-/9-/16-bit interface, make sure to
execute data transfer synchronization after reset operation.

R61509V Target Spec
Interface and Data Format
The R61509V supports system interface for making instruction and other settings, and external display
interface for displaying a moving picture. The R61509V can select the optimum interface for the display
(moving or still picture) in order to transfer data efficiently.
As external display interface, the R61509V supports RGB interface and VSYNC interface, which enables
data rewrite operation without flickering the moving picture on display.
In RGB interface operation, the display operation is executed in synchronization with synchronous signals
VSYNCX, HSYNCX, and DOTCLK. In synchronization with these signals, the R61509V writes display
data according to data enable signal (ENABLE) via RGB data signal bus (DB17-0). The display data is
stored in the R61509V’s GRAM so that data is transferred only when rewriting the frames of moving
picture and the data transfer required for moving picture display can be minimized. The window address
function specifies the RAM area to write data for moving picture display, which enables displaying a
moving picture and RAM data in other than the moving picture area simultaneously. To access the
R61509V’s internal RAM in high speed with low power consumption, use high-speed write function
(HWM = 1) in RGB or VSYNC interface operation.
In VSYNC interface operation, the internal display operation is synchronized with the frame
synchronization signal (VSYNCX). The VSYNC interface enables a moving picture display via system
interface by writing the data to the GRAM at faster than the minimum calculated speed in synchronization
with the falling edge of VSYNCX. In this case, there are restrictions in setting the frequency and the
method to write data to the internal RAM.
The R61509V operates in either one of the following four modes according to the state of the display. The
operation mode is set in the external display interface control register (R0Ch). When switching from one
mode to another, make sure to follow the relevant sequence in setting instruction bits.

Notes: 1. Instructions are set only via system interface.
2. When RGB interface is used, instructions should be transferred via clock synchronous serial
interface.
3. RGB and VSYNC interfaces cannot be used simultaneously.
4. Do not make changes to the RGB interface operation setting (RIM1-0) while RGB interface is
in operation.
5. See the “External Display Interface” section for the sequences when switching from one mode
to another.

Internal clock operation
The display operation is synchronized with signals generated from internal oscillator’s clock (OSC) in this
mode. All input via external display interface is disabled in this operation. The internal RAM can be
accessed only via system interface.
RGB interface operation (1)
The display operation is synchronized with frame synchronous signal (VSYNCX), line synchronous signal
(HSYNCX), and dot clock signal (DOTCLK) in RGB interface operation. These signals must be supplied
during the display operation via RGB interface.
The R61509V transfers display data in units of pixels via DB17-0 pins. The display data is stored in the
internal RAM. The combined use of window address function can minimize the total number of data
transfer for moving picture display by transferring only the data to be written in the moving picture RAM
area when it is written and enables the R61509V to display a moving picture and the data in other than the
moving picture RAM area simultaneously.
The front porch (FP), back porch (BP), and the display (NL) periods are automatically calculated inside the
R61509V by counting the number of clocks of line synchronous signal (HSYNCX) from the falling edge of
the frame synchronous signal (VSYNCX). Make sure to transfer pixel data via DB17-0 pins in accordance
with the setting of these periods.

R61509V Target Spec
RGB interface operation (2)
This mode enables the R61509V to rewrite RAM data via system interface while using RGB interface for
display operation. To rewrite RAM data via system interface, make sure that display data is not transferred
via RGB interface (ENABLE = high). To return to the RGB interface operation, change the ENABLE
setting first. Then set an address in the RAM address set register and R22h in the index register.
VSYNC interface operation
The internal display operation is synchronized with the frame synchronous signal (VSYNCX) in this mode.
This mode enables the R61509V to display a moving picture via system interface by writing data in the
internal RAM at faster than the calculated minimum speed via system interface from the falling edge of
frame synchronous (VSYNCX). In this case, there are restrictions in speed and method of writing RAM
data. For details, see the “VSYNC Interface” section.
As external input, only VSYNCX signal input is valid in this mode. Other input via external display
interface becomes disabled.
The front porch (FP), back porch (BP), and the display (NL) periods are automatically calculated from the
frame synchronous signal (VSYNCX) inside the R61509V according to the instruction settings for these
periods.
FMARK interface operation
In the FMARK interface operation, data is written to internal RAM via system interface synchronizing with
the frame mark signal (FMARK), realizing tearing-less moving picture while using conventional system
interface. In this case, there are restrictions in speed and method of writing RAM data. See “FMARK
interface” for detail.
