R61509V Target Spec
Description
The R61509V is a single-chip liquid crystal controller driver LSI for a-Si TFT panel, incorporating RAM
for a maximum 240 RGB x 432 dot graphics display, gate driver, source driver and power supply circuits.
For efficient data transfer, the R61509V supports high-speed interface via 8-/9-/16-/18-bit ports as system
interface to the microcomputer. As moving picture interface, the R61509V also supports RGB interface
(VSYNCX, HSYNCX, DOTCLK, ENABLE and DB17-0).
The power supply circuit incorporates step-up circuit and voltage follower circuit to generate TFT liquid
crystal panel drive voltages.
The R61509V’s power management functions such as 8-color display and shut down and so on make this
LSI an ideal driver for the medium or small sized portable products with color display systems such as
digital cellular phones or small PDAs, where long battery life is a major concern.

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.
