Tjmax = 125 [°C] Toprmax = 75 [°C] θja = 43 [°C/W] (When mounted on 4-layer substrate, wind speed 0m/s) Under these conditions, PDmax, the maximum allowable power dissipation for the package, is as follows. PDmax = (125 – 75)/43 = 1162 [mW] Furthermore, if the operating frequency of this IC exceeds 85MHz, the junction temperature may exceed its maximum value depending on conditions of use. Use this IC under conditions where the maximum value for the junction temperature will not be exceeded by lowering the thermal resistance of the package as follows by taking thermal countermeasures at this time.

The initialization of the internal circuit should be also performed by maintaining the system clear pin at low during the specified time after setting the supply voltage in the range of recommended operating conditions and stabilizing as shown in the figure below.

Description of I/O Pins (a) System clear pins (XCLR1, XCLR2 and XCLR3) All internal circuits are initialized by setting XCLR1 (Pin 102) low. In addition, the internal PLL is initialized by setting XCLR2 (Pin 66) low, and RGB output is initialized (preset) by setting XCLR3 (Pin 103) low. Initialization should be performed when power is turned on. (b) Sync signal input pins (HDIN and VDIN) Horizontal and vertical separate sync signals are input to HDIN (Pin 62) and VDIN (Pin 17), respectively. The CXD3526GG supports only non-interlace sync signals with a dot clock of 100MHz or less. (c) Master clock input pins (CLKP/CLKN, CLKC, CLKSEL and CLKPOL) Phase comparison is performed by an external circuit and a clock synchronized to the sync signal is input. The master clock input pins have two systems consisting of CLKP/CLKN (Pins 101 and 130) for small-amplitude differential input (center level: 2.0V, amplitude: ±0.4V), and CLKC (Pin 131) for CMOS level input. In addition, the clock path selection is performed with CLKSEL (Pin 100) and CLKPOL (Pin 63). The setting values are as follows. CLKSEL: 0 = CLKP and CLKN input; 1 = CLKC input CLKPOL: 0 = Input clock is non-inverted; 1 = Input clock is inverted (d) PLL setting pin (PLLDIV) PLLDIV (Pin 129) sets the divider setting of the internal phase compensation PLL circuit. The setting values for master clock frequency are as follows. PLLDIV: 0 = 55 to 100MHz; 1 = 27.5 to 55MHz Note that the frequency of the clock input to the CXD3526GG must be within the phase compensation PLL operating range, even during free running. (e) RGB signal input pins (RIN, GIN and BIN) These pins input RGB digital signals in 10 bits. The Red signal is input to RIN (Pins 4 to 6, 50 to 53 and 89 to 91), the Green signal to GIN (Pins 7, 8, 54, 55, 92, 93 and 123 to 125), and the Blue signal to BIN (Pins 9 to 12, 56 to 58 and 95 to 97) respectively. (f) OSD signal input pins (ROSD, GOSD, BOSD, YS and YM) These pins input OSD signals. The Red signal is input to ROSD (Pins 14 and 59), the Green signal to GOSD (Pins 15 and 60), and the Blue signal to BOSD (Pins 16 and 61) respectively. In addition, the YM signal is input to YM (Pin 98), and the YS signal to YS (Pin 99). – 11 – CXD3526GG (g) Host I/F serial clock input pin (HSCL) HSCL (Pin 68) is the clock input pin used to set the I/O timing for serial data from the host. Data is taken from the HSDA pin when the clock signal rises, and data is output to the HSDA pin when the clock signal falls. (h) Host I/F serial I/O pin (HSDA) This is the I/O pin for serial data from the host. It is necessary to switch the input to the HSDA (Pin 70) while the signal level of HSCL is low. (i) Slave address input pin (HSEL) With this IC, it is possible to select host I/F slave address. Since a slave address is used to identify each of these devices, this pin should be connected to VDD or Vss externally. This VDD and Vss setting drives the device which matches the slave address input from the HSDA pin. The slave addresses of this IC used for the HSEL (Pin 22) setting are as follows. HSEL: 0 = 74h; 1 = 76h (j) External ROM I/F serial clock output pin (RSCL) RSCL (Pin 23) is the clock output pin used to set the I/O timing of serial data sent to the external EEPROM. Data is taken from the RSDA pin when the clock signal rises, and data is output to the RSDA pin when the clock signal falls. (k) External ROM I/F serial I/O pin (RSDA) This is the I/O pin for serial data sent to the external EEPROM. It is necessary to switch the input to the RSDA (Pin 69) while the signal level of RSCL is low. 2. Pipeline Delay of the RGB and OSD Signals The pipeline delay for the I/O of the RGB signals is 32 clock cycles of the master clock. In addition, the pipeline delay for the OSD, YS and YM signals is 25 clock cycles of the master clock. – 12 – CXD3526GG 3. Serial Bus The serial bus of this IC consists of a host I/F, external ROM I/F and register I/F. 3-1. Host I/F With this IC, each register setting and data set to built-in RAM are performed over a serial bus. Bus protocol conforms to I2C bus specifications. Note that this IC does not support multi-slave functions, and that the bus should be independent from ICs having the other I2C bus specification. Also, when accessing gamma RAM, always access memory address from odd addresses in 2-byte units. The following restrictions are placed on the host I/F of this IC. • • • • • • • Only I2C bus slave operations are performed. Standard mode and fast mode are supported. Hs mode is not supported. Multi-slave functions are not supported. The general call address and start byte of the slave address are not acknowledged. C bus compatibility is not supported. Acknowledgment is not performed for 10-bit slave addresses. Low is not asserted for HSCL. (Wait control is not performed.) (1) "Start" conditions Read and write operations enter "Start" status by switching HSDA input from high to low level while HSCL input is high. (2) "Stop" conditions "Stop" results by switching HSDA input from low to high while HSCL input is high. Setting "Stop" status causes read processing to terminate during read operations, and causes the input of write data to terminate during write operations. HSDA HSCL "Start" "Stop" "Start" Conditions and "Stop" Conditions – 13 – CXD3526GG (3) Acknowledgment Acknowledgment is used to indicate whether or not data has been sent/received normally. The "Acknowledgment" of a data transfer is performed after that data transfer when the sender releases the bus on the 9th clock of HSCL and the receiver drives low. If the host is the receiver, the IC is informed by the host that data has ended by the fact that "Acknowledgment" is not generated for the last data sent from the IC. HSDA in Not acknowledged HSDA out Acknowledged HSCL 1 2 8 9 "Start" "Acknowledgment" Acknowledgment on the I2C Bus (4) Slave address specification After "Start" is sent, a 7-bit slave address and 1-bit read/write code is sent. Read/write operations with this IC start if the input slave address matches the device address set using HSEL. If the device address does not match, "Acknowledgment" is not generated and the system does nothing. Slave Address Word (8 bits) Device Code (fixed) 0 1 1 1 0 1 Device Select R/W Code HSEL R/W ∗ If R/W = 1, read results, if R/W = 0, write results. Slave Address Specification (5) Byte write operation After "Start" is sent, the R/W code is set to low and an 8-bit device address word is input. The IC outputs "Acknowledgment" on the 9th bit and enters write mode. After this, "Acknowledgment" is output every 8 bits after each of the two 8-bit memory addresses are input. Next, "Acknowledgment" is output after 8 bits of write data is input and written to the IC.

With the continuous write operation, write data is written in a manner similar to the byte write operation. Continuous write is possible by sending write data continuously before sending "Stop". The address used to write data during the continuous write operation is automatically incremented when each separate write operation terminates.

There is no limit on the number of continuous transfers that are possible to read continuously with this IC. CXD3526GG 3-2. Conditions for Accessing Gamma RAM and Color Shading RAM With this IC, there are two way to access the internal RAM: by the host I/F using the serial bus and refresh/ write-back for sending/receiving data via external ROM I/F. In the case of Gamma RAM, internal RAM must be accessed by the host I/F in 2-byte units, and memory address must be read from or written to odd memory addresses. Color shading RAM can be accessed in 1-byte units and there is no restriction on which addresses can be read or written. It is possible to access internal RAM from each I/F when the conditions given in the following table are established. GAM_ON Vertical blanking period Gamma RAM access 0 — Yes 1 Vertical blanking period Yes 1 Outside vertical blanking period No ∗ GAM_ON represents the setting value of the DSD register. ∗ Gamma correction is not performed when GAM_ON is "0", and is performed when GAM_ON is "1". Conditions for Accessing Gamma RAM CSC_ON Vertical blanking period Color shading RAM access 0 — Yes 1 Vertical blanking period Yes 1 Outside vertical blanking period No ∗ CSC_ON represents the setting value of the color shading register. ∗ Color shading correction is not performed when CSC_ON is "0", and is performed when CSC_ON is "1". Conditions for Accessing Color Shading RAM GAM_ON must be set to "0" when performing a write-back or forced refresh operation for Gamma RAM. Similarly, CSC_ON must be set to "0" when performing a write-back or forced refresh operation for color shading RAM. In the case of a self-refresh operation, the start of vertical blanking period is automatically detected and operations start automatically at that time, regardless of how GAM_ON and CSC_ON are set. Therefore, be sure to set the external EEPROM transfer count register ROM_TRAN to fit within the vertical blanking period. Furthermore, the vertical blanking period for gamma is set using GAM_H1, GAM_H2, GAM_V1 and GAM_V2, while the vertical blanking period for color shading is set using CSC_HP, CSC_VP, CSC_HNUM, CSC_VNUM, CSC_HINT and CSC_VINT. Make all settings in accordance with the specifications of the video signal attempting to be displayed. – 17 – CXD3526GG 3-3. External ROM I/F When operating the external ROM I/F, operations start by setting the serial bus register from the host I/F. The serial bus on the ROM side is used to access the external EEPROM. Bus protocol conforms to I2C bus specifications. Also, the following restrictions are placed on the external ROM I/F of this IC. • • • • • • • • Only master operations are performed. Standard mode and fast mode are supported. Hs mode is not supported. Multi-master functions are not supported. The general call address and start byte of the slave address are not generated. C bus compatibility is not supported. A memory address space of up to 512K bytes is supported. Wait control by RSCL is not supported. 10-bit slave addresses are not supported. (1) External ROM I/F clock settings The frequency of the clock signal supplied to the external EEPROM by the RSCL pin is set using RSCL_SEL of the serial bus control registers. Set this value based on the operating frequency of the IC as given in the table below so that the frequency output by the RSCL pin is appropriate for the specifications of the external EEPROM. RSCL_SEL Operating frequency 00 35MHz or less 01 70MHz or less 10 94.5MHz or less 11 100MHz or less (2) External EEPROM memory capacity setting With this IC, slave addresses and memory addresses are generated in accordance with the memory capacity set for the external EEPROM. The memory capacity of the external EEPROM is set using ROM_MAP of the serial bus control registers. ROM_MAP Usable memory size 00 512K-bit (65,536 × 8-bit) 01 256K-bit (32,768 × 8-bit) 10 128K-bit (16,384 × 8-bit) 11 64K-bit (8,192 × 8-bit) – 18 – CXD3526GG [Example] Address output when using eight 256K-byte EEPROMs (ROM_MAP = 01) With this IC, the ROM slave address register setting [7:4] is set as is for the serial bus slave address [7:4], and the memory address [17:15] is used for the slave address [3:1]. The memory address [14:0] is used as is for the 1st and 2nd memory addresses. The 1st memory address [7] is fixed to all "0". Furthermore, up to eight external EEPROMs can be connected to this IC.

Since operations conform to I2C bus protocol just as with the host I/F, this section only describes the slave address. To access the external EEPROM, when access conditions are established, "Start" is sent, and then 7 bits representing the slave address are output, and the R/W code is output. "Acknowledgment" is received to the 9th bit from the external EEPROM, and the IC enters either read or write mode. The slave address is determined based on ROM_MAP of the serial bus ROM I/F control register and RSLV_ADDR of the serial bus ROM slave address register as previously described. The user should set the upper 4 bits of the device address of the EEPROM to be used in RSLV_ADDR and the memory size in ROM_MAP. This allows memory to be used without awareness of memory boundaries of actual memory used for the setting memory space.

The registers used to make these settings are the external EEPROM gamma data start address register and the external EEPROM color shading data start address register. By specifying the starting position of the data area in these registers data access from the specified addresses is possible during refresh or write-back operation. Units of 1K-byte can be used to set the start addresses which can be set in these registers. In addition, the size of data transferred during refresh and write-back operations is fixed at 2K bytes for each color in the case of gamma data. The number of bytes transferred in the case of color shading data is the value stored in the color shading data size register plus one. – 20 – CXD3526GG (5) Refresh and write-back operations This IC includes a function that allows an external EEPROM to automatically refresh the internal RAM. This function has the four modes described below. • • • • Self-refresh mode Forced refresh mode Write-back mode Refresh stop mode Each mode is started by writing the specified mode into REF_MODE of the refresh register. In self-refresh mode, the IC detects that the vertical blanking period has been entered and, using the value specified in the external EEPROM transfer count register, uses the continuous read operation to transfer data of the size "transfer count plus 1" to the external ROM I/F. The data read using the continuous read transfer is written into the internal RAM. When the transfer of the all data for the data size is completed, the access area for the internal RAM is changed, continuous read transfer is executed indefinitely until self-refresh mode is exited, and refresh operations are automatically carried out on the internal RAM. In forced refresh mode, continuous read transfer from the external EEPROM is performed for the RAM area specified by REF_RSEL of the refresh RAM select register, and the read data is written to the internal RAM. When the transfer of all data for the specified RAM area is completed, REF_END of the refresh status register set to a flag indicating the operation has ended, and operations stop. If forced refresh operations are to be performed for the entire internal RAM, first set the refresh RAM select register to gamma RAM (R) and perform the forced refresh operation. Since the refresh RAM select register is automatically set to the next RAM area after all data is transferred, refresh for the entire RAM can be completed by repeating the forced refresh operation five times. In write-back mode, continuous write transfer is performed from the RAM area specified by REF_RSEL of the refresh RAM select register to the external EEPROM. When the transfer of all data for the specified RAM area is completed, REF_END of the refresh status register set to a flag indicating the operation has ended, and operations stop. If write-back operations are to be performed for the entire internal RAM, first set the refresh RAM select register to gamma RAM (R) just as for forced refresh operation, and then perform the write-back operation. Since the refresh RAM select register is automatically set to the next RAM area after all data is transferred, write-back for the entire RAM can be completed by repeating the write-back operation five times. In refresh stop mode, the external ROM I/F does not operate and nothing is output on the serial bus. (6) Forced reset of the external ROM I/F control circuit With this IC, forced reset is possible in case a problem occurs with the external ROM I/F and the internal circuit becomes locked. Forced reset initializes only the external ROM I/F control circuit by writing "1" to ROM_RST of the refresh register. Normal operations are allowed after initialization is complete. 3-4. Register I/F Control Circuit The register I/F control circuit transfers data between the host I/F and the external ROM I/F. Register data other than RAM data is stored here. Since registers have a double buffer configuration, data in the first buffer is synchronized with the internal VD and reflected in the second buffer, while data in the second buffer is input to each block. Note, however, that data in the serial bus control register has a single buffer configuration. – 21 – CXD3526GG 3-5. Software Flow (1) Settings when power is turned on The following procedure is the setting procedure first performed after power of the IC is turned on. If this procedure is not executed, the internal VD will not be generated and register data cannot be set correctly. Start Perform settings such as for the timing of the corresponding LCD panel using the TG register. Since the TG register uses a double register configuration using a V latch, set the FORCE_VD register of the serial bus control register to "1" only at startup to transfer TG register setting values. Perform setting for unset registers. If TG is operating at this time, there is no need to write the FORCE_VD register due to the fact that registers having a double register configuration will be automatically written using VD from an external source. End (2) Setting procedure of the serial bus control register The following procedure is the procedure for setting the serial bus control register in accordance with the external EEPROM to which the IC is connected. Be sure to make settings according to the operating frequency of the IC and the speed, capacity and number of external EEPROMs that are connected. Start Find the optimum clock frequency for the external ROM I/F based on the frequency of the system clock and set the Bits 1 and 0 of the RSCL_SEL register to this value.

The half-tone processing setting is as follows. YM signal input: 1 = Half-tone processing ON, 0 = OFF Here, the video signal level is halved by shifting the input data by one bit to the LSB side when YM = 1. For example, when 0F0h is input, 078h is output. The selector selects one of four types of data with respect to the OSD signal value as shown in the table below. The selected data becomes the OSD signal gradual data. The selected gradual data can be set independently in 10 bits for R, G and B, so 4 graduation can be selected as desired from among 1024 graduation for each of R, G and B. Therefore, the desired 64 (= 2^6) colors can be selected from among the total 1.07374 billion (= 2^30) colors for R, G and B.

GAM_ON: 1 = Gamma correction processing ON, 0 = Gamma correction processing OFF GAM_MODE: 1 = Normal operation mode, 0 = Power-saving mode GAM_H1, GAM_H2: 1 = Gamma correction processing range is set in 1-dot units GAM_V1, GAM_V2: 1 = Gamma correction processing range is set in 1-line units (All settings shared by R, G and B) When operating the RAM, be sure to set GAM_MODE = 1. Data cannot be written to or read from the RAM in power-saving mode. The RAM data is set through the host I/F block or external ROM I/F. Set gamma correction processing range (effective period of video signal) to GAM_H1 and GAM_H2, and GAM_V1, GAM_V2. This setting enables access to RAM from serial bus. Note that the RAM output is undetermined during power-on. RAM ON/OFF Data path selection 10 RAM 10 bits × 1024 words Input 10 Selector 10 Output (j) Gamma gain This block performs multiplication processing to correct VT curve variation of the LCD panel as gain adjustment for the gamma corrected signal. The settings are as follows. Coefficient: 8 bits Gain setting: 0 to 1.9921875 (= 255/128) times, variable in 256 steps (Set independently for R, G and B) Multiplication is performed using the 10-bit input and an 8-bit coefficient, and the upper 12 bits c[17:6] of the operation results are output. Next, the c[6] value is checked and rounding is performed to 11 bits. The MSB of the rounded 11 bits is checked, clipping is performed, and the lower 10 bits are output. Coefficient b[7:0] 8 Input 10 a[9:0] a×b Rounding and clipping 12 c[17:6] – 43 – 10 Output CXD3526GG (k) Gamma bright This block performs addition and subtraction processing to correct VT curve variation of the LCD panel as bright adjustment for the gamma corrected signal. The settings are as follows. Coefficient: 11 bits with code, MSB = code bit Bright setting: –1024 to +1023 graduation, variable with an accuracy of 1 bit (Set independently for R, G and B) Multiplication is performed using the 10-bit input and a 11-bit coefficient with code. The coefficient MSB is the code bit. Addition is performed when b[10] = 0, and subtraction when b[10] = 1. However, when performing subtraction, set the two's complement in the lower bits of the coefficient. When the operation results overflow or underflow, clipping is performed. Coefficient b[10:0] 11 Input 10 a[9:0] Addition/subtraction and clipping – 44 – 10 Output CXD3526GG (l) Color shading correction This block corrects color shading by adding a correction signal to the video signal. Correction points are set at fixed intervals in the horizontal, vertical and gradual directions of the video signal. The correction data for these correction points is written in the RAM, and a correction curve is created by reading this data and performing interpolation operations. The settings are as follows. CSC_ON: 1 = Color shading correction processing ON, 0 = Processing OFF CSC_R (G, B)_RGT∗: 1 = Reflects the TG block RGT setting, 0 = Reflects the inverse of the TG block RGT setting CSC_DWN: 1 = Reflects the TG block DWN setting, 0 = Reflects the inverse of the TG block DWN setting CSC_HP: Sets the horizontal correction start position CSC_VP: Sets the vertical correction start position CSC_HNUM: Sets the number of horizontal correction points CSC_VNUM: Sets the number of vertical correction points CSC_HINT: Sets the horizontal correction interval CSC_VINT: Sets the vertical correction interval CSC_HOS: Sets the expansion of the horizontal correction area CSC_VOS: Sets the expansion of the vertical correction area CSC_GNUM: Sets the gradual correction points CSC_R (G, B) GP1 to 8∗: Sets the gradual correction points CSC_R (G, B) GD1 to 8∗: Sets the expansion of the correction data CSC_XH_ON: 1 = Cross hatch insertion ON, 0 = OFF CSC_XH_DAT: Sets the cross hatch display level ∗: Set independently for R, G and B, Others: Settings shared by R, G and B The color shading correction data of the desired gradual level up to 8 screens (max.) can be set in RAM. The RAM size is 8 bits × 1792 words, so up to 1792 correction points can be set. The correction data is set as 8-bit data with code. Correction data can be set in the range of –128 to +127 graduation. The example shown on page 47 is for a 1024-dot × 768-line XGA video signal divided into 9 points at 128-dot intervals in the horizontal direction and 7 points at 128-line intervals in the vertical direction. The relationship between the correction point coordinates (m, n) and the RAM address is obtained as follows. RAM address = (m – 1) + (n – 1) × (Number of horizontal correction points) For the example on page 47, this is as follows. (9 – 1) + (7 – 1) × 9 = 62 Thus, the correction data must be set in the RAM from address 0 to address 62. – 45 – CXD3526GG If correction is to be performed in the gradual direction as well, the RAM address is found based on the relationship between the coordinates (m, n) of the correction points and the number of gradual correction points using the formula below: RAM address = (m – 1) + (n – 1) × (number of horizontal correction points) + (number of horizontal correction points) × (number of vertical correction points) × (number of gradual correction points – 1) If the number of gradual correction points is eight, it is necessary to set correction data into RAM from Address 0 to Address 503 as calculated below: (9 – 1) + (7 – 1) × 9 + 9 × 7 × 7 = 503 Correction data in the gradual direction for the screen 2 and subsequent planes is set in order from Address 63. This IC supports top/bottom and/or right/left inversion of the LCD panel by controlling the direction in which correction data that has been set into RAM is read. Up/down and/or right/left inversion are set from DWN and RGT of the TG block. CSC_DWN and CSC_R (G, B)_RGT control the link with the TG block settings. It is therefore unnecessary to reset correction data. The table below gives an example of setting correction points. Signal specification XGA (1024 × 768) SVGA (800 × 600) Correction gap Number of correction points H V H V G Total 64 64 17 13 8 1768 64 64 16 12 8 1536 50 50 17 13 8 1768 64 64 14 11 8 1232 64 64 13 10 8 1040 Example of Setting Correction Points – 46 – CXD3526GG This IC has two ways it can handle interpolation in the horizontal and vertical directions: by dividing the screen into a uniform grid and setting data for points at the intersections or by setting data for points in the center of each area. (1) When setting data for intersection points (pixels) on the screen The correction area is set for the entire screen. An interpolation operation uses 4 values nearby intermediate points to perform calculations. The correction start position is set using CSC_HP and CSC_VP. Be sure to set the start position for the effective period of the video signal. HDIN VDIN Correction start position 1 2 3 4 5 6 Number of correction points 7 8 9 (m, n) 4 5 6 7 Correction interval (128 dots) 768 lines 3 Correction interval (128 lines) 2 Number of correction points Correction start position 1 : Correction data that has been set in RAM : Interpolation operation results for the vertical direction : Interpolation operation results for the horizontal direction 1024 dots (2) When setting the correction point to the center of the areas dividing the screen The correction area is set to inside the screen. At this time, be sure to set the correction start position so it lies inside the screen. When the correction point is set to the center of the areas dividing the screen, it is necessary to virtually perform correction outside the correction area for which correction data is set. It is therefore assumed that the same data as at the edge of the correction area applies to outside the interpolation area, and linear interpolation is performed. Use CSC_HOS and CSC_VOS to set correction areas that are to be expanded. HDIN Correction start position VDIN Correction start position : Correction data that has been set in RAM : Data assumed to lie in invalid period : Area to be virtually corrected – 47 – CXD3526GG The number of correction points to be used by this IC for correction in the gradual direction can be set using CSC_GNUM. The number of correction points can be varied from 1 to 8 and settings are available for each RGB signal. This means that the gradual level for which correction is to be performed can be independently and freely set for each RGB signal using CSC_R (G, B) GP1 to 8. An interpolation operation uses 2 values nearby intermediate points to perform linear interpolation. If the number of correction points is 1, no interpolation operation is performed in the gradual direction. The results of interpolation for one screen are added to the video signal regardless of the gradual level of the video signal being input. Correction data for one screen is entered into RAM beginning from Address 0. When two or more correction points are used, interpolation in the gradual direction is performed according to the gradual level of the video signal being input. If the number of correction points is 2 through 7, be sure to set data into RAM for the number of screens equal to "the number of correction points plus 1", beginning from Address 0. In the example shown in the figure below, correction data is assigned when there are 5 correction points. In addition to the 5 correction points, data for Screen 1 (Correction Point 1) is assigned to 3FFh. Data for the Screen 6 (Correction Point 6) is assigned to 000h. In the case of the Screen 6, be sure to either set correction data for gradual level 000h or the same correction data as for Screen 5. In this time the value set by using CSC_R (G, B) GP6 is ignored. 3FFh Data for Screen 1 (Correction Point 1) Screen 1 (Correction Point 1) 300h 200h Screen 2 (Correction Point 2) Screen 3 (Correction Point 3) Screen 4 (Correction Point 4) Screen 5 (Correction Point 5) 100h 000h Data for Screen 6 (Correction Point 6) : Correction data that has been set in RAM : Interpolation operation results for the gradual direction Example of Settings for Five Correction Points When there are 8 correction points, be sure to set the data for the 8 screens into RAM beginning from Address 0. In addition to the 8 correction points, data for Screen 1 (Correction Point 1) is assigned to 3FFh as shown in the figure below. Data for Screen 8 (Correction Point 8) is assigned to 000h. 3FFh Data for Screen 1 (Correction Point 1) Screen 1 (Correction Point 1) 300h Screen 2 (Correction Point 2) Screen 3 (Correction Point 3) 200h Screen 4 (Correction Point 4) Screen 5 (Correction Point 5) Screen 6 (Correction Point 6) 100h Screen 7 (Correction Point 7) Screen 8 (Correction Point 8) 000h Data for Screen 8 (Correction Point 8) : Correction data that has been set in RAM : Interpolation operation results for the gradual direction Example of Settings for Eight Correction Points Furthermore, with this IC, correction data can be extended from 8 bits with code to 9 bits with code. This setting is made using CSC_R (G, B) GD1 to 8. This setting can be made separately for each correction point in the gradual direction as well as independently for each RGB signal. – 48 – CXD3526GG (m) Mute 2 This block performs mute processing by replacing the video signal with data of the desired level. The settings are as follows. MUTE2_ON: 1 = Mute processing ON, 0 = OFF (Setting shared by R, G and B) R, G, B_MUTE2: RGB mute data (Set independently for R, G and B) Processing ON/OFF Input Coefficient 10 10 10 Selector Output (n) Limiter This block performs limiter processing so that the output signal does not exceed a certain range. The settings are as follows. L_LIM_DAT: Low side limiter level When input data ≤ L_LIM_DAT, the output is clipped to L_LIM_DAT. H_LIM_DAT: High side limiter level When H_LIM_DAT ≤ input data, the output is clipped to H_LIM_DAT. (Both settings shared by R, G and B) Set data so that the relationship L_LIM_DAT < H_LIM_DAT is constantly maintained. When both coefficient values are 000h, limiter processing is not performed. Input Coefficient (H side) Coefficient (L side) 10 10 10 Limiter 10 – 49 – Ouput CXD3526GG (o) Ghost cancel This block uses signal processing to correct ghosting generated internally within the LCD panel. Correction is performed by attenuating the video signal and adding after 6 or 12 dots. Equipped with a limiter, the following settings result in processing only for a video signal of a set level or higher. GC_ON: 1 = Ghost cancel processing ON; 0 = OFF (Settings shared by R, G and B) GC_MODE: 1 = 12-dot period processing ON; 0 = 6-dot period processing (Settings shared by R, G and B) R (G, B)_GC_ATT: 8-bit gain data (Set independently for R, G and B) The difference between the video signal prior to 6 or 12 dots and the video signal of dots for which processing is to be performed is found. Attenuation is performed based on this difference and added to the video signal to correct ghosting. In addition, settings can be made so that a limiter is used to ensure processing is performed only when the difference in the video signals is of a set level or higher. Level selection Input 10 Shift Register Processing Coefficient ON/OFF Coefficient Arithmetic unit Limiter Attenuator 6 levels or 12 levels + – 50 – – Clip processing Output CXD3526GG (p) Cycle offset This block performs addition and subtraction processing for port. Arithmetic coefficients are selected sequentially using the counter output value as the select signal. Therefore, a cyclic offset relative to the video signal can be attached. The settings are as follows. OFFSET_ON: 1 = Offset processing ON, 0 = OFF (Setting shared by R, G and B) OFFSET_MODE: 0 = 6-dot period, 1 = 12-dot period (Setting shared by R, G and B) R (G, B)_OFFSET1 to 12: 4-bit offset data with code –8 to +7 graduation, variable with an accuracy of 1 bit (Set independently for R, G and B) The counter operation selects offset data sequentially from R (G, B)_OFFSET1. The offset data MSB is the code bit. Addition is performed when MSB = 0, and subtraction when MSB = 1. However, when performing subtraction, set the two's complement in the lower bits of the coefficient. When the operation results overflow or underflow, clipping is performed.

(e) RSLV_ADDR[7:4] (sub address: 0001h) This sets the slave address of the external EEPROM. Although addresses of reserved areas can be set, be sure to set appropriate addresses. The lower portion of the slave addresses is determined by memory mapping. – 53 – CXD3526GG (f) GAM_ADDR[18:10] (sub addresses: 0002h and 0004h) This sets the start address ([18:10]) used when storing gamma correction data on the external EEPROM.

(i) ROM_TRAN[10:0] (sub addresses: 0007h and 0008h) The lower 11 bits are used to set "the number of bytes – 1" to be transferred per access for the external EEPROM during refresh and write-back operations. (j) ROM_RST (sub address: 0009h) This causes forced reset of the external ROM I/F circuit. A reset is executed when "1" is written to this bit. "0" is read during read operations. (k) REF_MODE[1:0] (sub address: 0009h) This sets the operation settings for the refresh circuit. Setting values are as follows. 00: Refresh stop mode During refresh stop mode, internal RAM can be accessed by the host. 01: Self-refresh mode During self-refresh mode, internal RAM cannot be accessed by the host. Refresh starts when vertical blanking starts. 10: Forced refresh mode Used to transfer external EEPROM data to internal RAM at times such as during Power ON. The external EEPROM address for data to be transferred is determined based on each start address register. Whether the data being transferred is gamma data or color shading data is determined by REF_RSEL[2]. Refresh starts when this mode is set. 11: Write-back mode Internal RAM data is transferred to external EEPROM in order to write data to external EEPROM at times such as during manufacture. The external EEPROM address of data to be transferred is determined by each start address register. Whether the data being transferred is gamma data or color shading data is determined by REF_RSEL[2]. Write-back starts when this mode is set. Each of these modes can be executed by writing these bits. – 54 – CXD3526GG (l) REF_RSEL[2:0] (sub address: 000Ah) Sets whether to access the gamma RAM area or color shading RAM area during write-back and refresh modes. In addition, the area to be accessed automatically changes to the next access area when all transfers for a given area have been completed. The order in which area are accessed is: Gamma (Red) → Gamma (Green) → Gamma (Blue) → Color shading (Red) → Color shading (Green) → Color shading (Blue) → Gamma (Red).

Cleared when "1" is written to this bit. Status: 0 = Succeeded in accessing external EEPROM; 1 = Failed in accessing external EEPROM If the external EEPROM is being written during write-back, ACK is not returned by Ack Polling. This means that "1" is set for this bit during Ack Polling. However, this bit is automatically cleared when the write operation is complete and ACK is returned by Ack Polling. (p) REF_END (sub address: 000Ch) Indicates that forced refresh or write-back operations are complete. Cleared when "1" is written to this bit.

Setting value: 1 = Internal clock is inverted and output, 0 = Low is output (b) SYNC polarity settings (1) POLDET (sub address: 1000h) This sets the sync polarity auto discrimination function ON/OFF. Setting value: 1 = Auto discrimination function ON, 0 = Auto discrimination function OFF When POLDET = 1, the HPOL and VPOL settings below are invalid. When using this function, the HDIN sync portion must be 1/2 or less of 1H, and the VDIN sync portion must come before the rise position of the VST pulse. HDIN (Negative) N/2 or less N VDIN (Negative) Must come before VST VST (2) HPOL and VPOL (sub address: 1000h) These set the sync signal polarity when POLDET = 0. Setting value: 1 = Positive polarity, 0 = Negative polarity The internal operation of this IC is with the input sync signal fixed to positive polarity. Therefore, these HPOL and VPOL must be set in accordance with the polarity of the sync signal input from HDIN and VDIN. Set HPOL and VPOL to "1" when the input sync signal is positive polarity, or to "0" when negative polarity. – 58 – CXD3526GG (c) Dots per 1H and lines per 1V settings (1) HR (sub address: 1000h) This sets the PLL counter reset ON/OFF. Setting value: 1 = Reset enabled, 0 = Reset disabled When HR = 0, the internal frequency divider is used, and the HD1 pulse output should be used as the return pulse. The number of dot clocks per 1H is set by PLLP[11:1] below. (2) PLLP[10:0] (sub addresses: 1004h and 1005h) This sets the internal PLL counter reset period in 11 bits. Setting is possible in 1-dot units. When HR = 0, free-running occurs at the above N. When HR = 1, if the next HDIN is not input before the internal PLL counter counts up to 2047, free-running mode is established and free-running occurs at N. When HDIN is input, free-running is canceled and normal operation is established. (3) VFRRN[10:3] (sub address: 1003h) This sets the number of lines in 9 bits during vertical free running. Setting is possible in 4-line units. To have operation run freely at M lines, set the "(M – 4)/4" value. If the next VDIN is not input before the internal vertical line counter counts up to 2047, free-running mode is established. When VDIN is input, free-running is canceled and normal operation is established.

The position can be set in 1-dot units using the internal pulse INT_HD generated from the front edge of HDIN as the reference. The HP setting range is from "0 to (N – 1)". If the HP value is set to the number of frequency divisions N or higher, the HP setting is ignored and "(N – 1)" is used as the setting value. The HST‚ PST, HCK1, HCK2, DCK1, DCK2, ENB, VST, VCK, FRP, XFRP, PCG, BLK, HD2 and HD3 horizontal timing pulses are linked according to the HP setting. The internal reference pulse INT_HD rises at the 5th clock from the front edge of the HDIN input, and all the pulses are synchronized using this as the reference. Increasing HP shifts the output positions of the linked pulses toward the rear of the time series. The example below shows the shortest output position from HDIN when HP is set to 000h. (Note that the output position changes according to the settings in (2) below.)

The respective rise and fall positions can be set in 1-dot units. Settings ending in "U" set the rise position, and settings ending in "D" set the fall position. Horizontal pulses are divided into the following two types. (A) CLP and HD1 → Pulses synchronized to the PLL counter Set the "rise position/fall position – 5" value. (B) PRG, SHST, PCG, ENB, HD2 and HD3 → Pulses synchronized to the HP counter Set the "rise position/fall position – HP setting value – 8" value. An outline of each type is shown below. When ∗∗U and ∗∗D are set to the same value, "1" is output. HDIN 0 0 PLL counter 0 0 HP counter HP[10:0] ∗U (A) ∗D ∗U (B) ∗D (3) HD1OE, HD2OE, HD3OE, CLPOE, PRGOE, SHSTOE, PCGOE and CLROE (sub addresses: 102Ch and 102Dh) These set the output limit of HD1, HD2, HD3, CLP, PRG, SHST, PCG and CLR pulses, respectively.

Reset is applied when the internal HP counter reaches "0", and the HST and PST pulse phases within 1H can be set at the HCK1 and HCK2 period, respectively, by HSTPC and PSTPC. HSTPF and PSTPF can set the HST and PST pulse phase relative to HCK1 and HCK2 in 1-dot units. Do not set HSTPC and PSTPC to 00h, as the pulses may not be output correctly in this case. The HSTPF and PSTPF values can be set up to "(HCKC × 2 – 2)". If higher values are set, the pulses are not output. Set the "(phase difference from HCK pulse)" value. The figures below show the timings for HSTPC: 04h and HSTPF: 04h, respectively. These timings are the same for the PST pulse.

Settings which result in an odd number for Tckw in the figure below are prohibited, so be sure to set a value that results in an even number. Set the "(Tckw – 1)" value according to the LCD panel specifications. When this setting is changed, the HST and PST pulse phases also change, so first set HCKC to the correct value and then make the HST and PST settings. Example setting values are shown in the table below. LCD panel Tckw HCKC SVGA 12 clk 0Bh XGA, WXGA 24 clk 17h CLK HCK1 Tckw (2) HCKFIX and HCKPOL (sub addresses: 1002h and 1001h) These set the HCK1 and HCK2 pulse output polarity.

DCKF sets the DCK1 and DCK2 pulse phases relative to HCK in 0.5-dot units. Set the "Tdckf" value. The DCKFINV, DCKFIX and RGT settings differ according to whether the phase is synchronized with the rising edge of HCK1 or HCK2. The DCK1 and DCK2 pulse width can be set in 1-dot units by DCKW. Set the "Tdckw – 1" value. HCK1 HCK2 Tdckw Tdckf DCK1 Tdckf Tdckw DCK2 (2) DCKPOL (sub address: 1001h) This setting switches the DCK1 and DCK2 pulse output polarities.

Setting value: 1 = Pulses are output, 0 = Output is fixed to "0" – 65 – CXD3526GG (k) LCD panel sample-and-hold position setting SHP[5:0] (sub address: 1015h) This sets the horizontal transfer start pulse and clock pulse phases relative to the video signal to the LCD panel. The phase can be set in 64 positions with 6 bits. Incrementing SHP by +1 shifts the HST, PST, HCK1, HCK2, DCK1 and DCK2 pulses forward by 0.5 dot (half the internal clock period). The LCD panel sample-andhold position can be set by shifting the above pulse phases forward or backward relative to the video signal. At this time, the phases between the HST, PST, HCK1, HCK2, DCK1 and DCK2 pulses do not change. The figure below shows an example of HCK1 during 12-dot simultaneous sampling. This setting eliminates the need to set the sample-and-hold position with a Sony sample-and-hold driver IC, and makes it possible to adjust the phases of the video signal to the LCD panel and the horizontal transfer clock without changing the position of the video signal on the screen. Video signal to LCD panel HCK1 SHP increased SHP decreased CLK – 66 – CXD3526GG (l) VST and VCK pulse settings (1) VSTP[10:1] (sub addresses: 1021h and 1025h) This sets the VST pulse rise and fall positions within 1H in 10 bits.

Using a multi-layer substrate and a solid ground is recommended. • Connect each power supply pin to GND via a ceramic chip capacitor of 0.1µF or more located as close to each pin as possible. • Do not use this IC under conditions other than the recommended operating conditions. • Absolute maximum rating values should not be exceeded even momentarily. Exceeding that ratings may damage the device, leading to eventual breakdown. • This IC has a MOS structure which is easily damaged by static electricity, so thorough measures should be taken to prevent electrostatic discharge. • Since this IC utilizes a MOS structure, it may latch up due to excessive noise or power surge greater than the maximum rating of the I/O pins, interface with two power supplies of another circuit, or the order in which power is supplied to circuits. Make a thorough study of measures against the possibility of latch up before use. • When the initialization of this IC is performed at power-on, system clear cancellation is performed after the supply voltage is set in the range of the recommended operating conditions and stabilized. Keep in mind that the internal circuit may not be initialized correctly if system clear cancellation is performed before the supply voltage is set in the range of the recommended operating conditions. • When designing the substrate, take sufficient care for the surrounding temperature and heat radiation, and make sure the IC junction temperature does not exceed the maximum value. • Be sure to make the number of dot clocks input to the CXD3526GG in 1H an even number. Note that if there is an odd number of dot clocks, the internal phase compensation PLL will not operate properly. • Be sure to make a thorough evaluation of any items not listed in this data sheet. – 86 – CXD3526GG TG output TG output Red output 0.1µ Application Circuit CTRL +2.5V 2 3 49 88 47 48 46 45 87 120 86 119 44 118 143 43 42 83 84 117 142 116 141 41 82 115 38 39 40 36 79 80 81 35 78 113 +3.3V Green input 0.1µ RGT XRGT DWN CTRL PO1 PO2 ENB PRG DCK1 DCK2 CLR SHST VDD2 FRP XFRP HD3 HD2 HD1 PCG HCK1 HCK2 HST PST VST VCK CLP ROUT9 ROUT8 ROUT7 ROUT6 ROUT5 ROUT4 ROUT3 ROUT2 ROUT1 ROUT0 1 48 47 46 45 44 43 42 41 40 39 38 37 2 49 88 87 86 85 84 83 82 81 80 79 36 3 50 89 120 119 118 117 116 115 114 113 78 35 4 51 90 121 144 143 142 141 140 139 112 77 34 5 52 91 122 138 111 76 33 6 53 92 123 137 110 75 32 7 54 93 124 136 109 74 31 8 55 94 125 135 108 73 30 9 56 95 126 134 107 72 29 10 57 96 127 128 129 130 131 132 133 106 71 28 11 58 97 98 99 100 101 102 103 104 105 70 27 12 59 60 61 62 63 64 65 66 67 68 69 26 13 14 15 16 17 18 19 20 21 22 23 24 25 Vss VDD2 VDD2 Vss VDD1 GOUT9 GOUT8 GOUT7 GOUT6 GOUT5 GOUT4 GOUT3 GOUT2 GOUT1 GOUT0 VDD2 Vss VDD1 BOUT9 BOUT8 BOUT7 BOUT6 BOUT5 BOUT4 BOUT3 BOUT2 BOUT1 BOUT0 Vss Vss Vss VDD2 CLKOUT Vss TEST4 TEST3 37 114 138 139 140 34 77 112 33 76 111 32 75 110 137 30 31 134 74 109 136 73 108 135 29 72 107 106 71 105 133 132 28 25 27 26 0.1µ 0.1µ 0.1µ 0.1µ 0.1µ 0.1µ Clock output 13 14 59 15 60 16 61 98 99 62 17 63 18 127 128 100 129 64 19 20 21 101 130 65 102 131 66 103 22 67 104 23 24 69 70 68 Vss ROSD0 ROSD1 GOSD0 GOSD1 BOSD0 BOSD1 YM YS HDIN VDIN CLKPOL TEST1 Vss VDD1 CLKSEL PLLDIV Vss Vss VDD1 Vss CLKP CLKN TEST5 XCLR1 CLKC XCLR2 XCLR3 HSEL TEST6 TEST7 RSCL TEST2 RSDA HSDA HSCL Blue input 0.1µ Vss Vss RIN9 RIN8 RIN7 RIN6 RIN5 RIN4 RIN3 RIN2 RIN1 RIN0 VDD2 Vss VDD1 GIN9 GIN8 GIN7 GIN6 GIN5 GIN4 GIN3 GIN2 GIN1 GIN0 VDD2 BIN9 BIN8 BIN7 BIN6 BIN5 BIN4 BIN3 BIN2 BIN1 BIN0 Green output 0.1µ 1 85 89 50 90 51 5 91 52 5 53 6 144 121 122 123 92 124 93 54 7 125 94 55 8 126 95 56 9 96 57 10 97 58 11 12 10µ Blue output Red input 10µ 0.1µ 0.1µ XCLR3 GND XCLR2 OSD input XCLR1 HDIN VDIN +3.3V CLKP 3.3k CLKN 3.3k HSCL CLKC HSDA +3.3V External CPU +3.3V 3.3k CLKPOL CLKSEL PLLDIV GND HSEL 3.3k External EEPROM SCL SDA Application circuits shown are typical examples illustrating the operation of the devices.
