| NJU6815 128COMMON x 80RGB LCD DRIVER FOR 4,096-COLOR STN DISPLAY ! GENERAL DESCRIPTION The NJU6815 is a 128COMMON x 80RGB LCD driver for 4,096-color STN display. It contains common drivers, RGB drivers, a serial and a parallel MPU interface circuit, an internal LCD power supply, grayscale palettes and 122,880-bit display data RAM. The segment drivers for RGB (Red, Green, Blue) independently produce optimum 16 grayscales from a built-in 32-grayscale palette, and the LSI achieves 4,096 colors (16x16x16). And the LSI features the display-rotation function which rotates an on-screen image in the unit of 90 degrees. In addition, the NJU6815 operates with a low voltage of 1.7V and a low operating current, therefore it is ideally suited for battery-powered handheld applications. PACKAGE BUMP CHIP !

When the RS is "L", the data is interpreted as display data which is stored in the DDRAM. The display data is latched at the rising edge of the WRb signal in the 80-series MPU mode, or at the falling edge of the E signal in the 68-series MPU mode. Table 7 RS L H Data Recognition Data Recognition Display Data Instruction In the DDRAM read sequence, be sure to execute a dummy read right after setting an address or right after writing display data or instruction. The data from MPU is temporarily held in the internal bus-holder, then released on the internal data-bus, therefore a dummy data is read out by the 1st "Display Data Read" instruction. After that, the display data is read out from a specified address by the 2nd instruction. Note that the "Display Data Read" instruction cannot be used in the serial interface mode.

In the 16-bit bus length mode, instruction as well as display data is transmitted to/from the instruction registers in 16 bits (D15 to D0). However, only lower 8 bits (D7 to D0) are valid for instruction register access. And only 12 bits are actually stored in the DDRAM, even though entire 16 bits (D15 to D0) are transmitted for DDRAM access. For more information, refer to "(4-4) Bit Assignment of Display Data". Table 8 WLS L H Selection of 8-/16-bit Bus Length Mode Bus Length Mode 8-bit Bus Length 16-bit Bus Length (2) INITIAL DISPLAY LINE REGISTER The address data in the initial display line register specifies the row address, which corresponds to an initial COM and is normally positioned on top of a screen in full display. The initial COM is the start position of common scanning, which is specified by the "Initial COM" instruction. The row address, which is established in the initial display line register, is preset into the line counter whenever the FLM becomes "H". At the rising edge of the CL signal, the line counter is counted-up, then 240-bit display data is latched into the data latch circuit. At the falling edge of the CL signal, the latch data is released to the grayscale control circuit to decide a grayscale level, then the segment drivers Ai, Bi and Ci (i=0 to 79) generate LCD waveforms. (3) COLUMN AND ROW ADDRESS COUNTERS The column and row address counters designate a column address and a row address respectively for DDRAM access, but they are completely independent from the line counter. The line counter provides a line address which is synchronized with display control timings such as the FLM and the CL. Ver.2003-10-07 - 19 - NJU6815 (4) DDRAM (4-1) DDRAM Address Range The DDRAM is capable of 128 bits for row address and 960 bits (12-bit x 80-segment) for column address. The range of the column address is from (00H) to (4FH), and the row address is from (00H) to (7FH). Setting outside these ranges is not allowed, otherwise it may cause malfunctions. For DDRAM access, two data transmissions are needed for 1 RGB-pixel in the 8-bit bus length mode, and one transmission in the 16-bit bus length mode. 8-bit Bus Length 00H 00H 7bit 5bit Column Address 7bit 4FH 5bit Row Address 7FH 7bit 00H 5bit Column Address 8bit 7bit 4FH 4bit 5bit ABS='1' 00H 4bit 8bit Row Address 7FH 4bit 00H 8bit 8bit 1H 8bit Column Address 4bit 4EH 8bit 8bit 4FH 8bit C256='1' 00H Row Address 7FH 8bit 8bit 8bit 8bit Fig 5 Range of Column Address in 8-bit Bus Length 16-bit Bus Length 00H 00H 12bit Column Address 4FH 12bit Row Address 7FH 12bit 12bit Fig 6 Range of Column Address in 16-bit Bus Length - 20 - Ver.2003-10-07 NJU6815 (4-2) Window Area for DDRAM Access Be sure to set up window area prior to DDRAM access. This area is set by the "Increment/Decrement Control" instruction and the designation of the start point and the end point. By the "Increment/Decrement Control", either auto-increment or -decrement is set for column address and row address individually. Once this mode is set up, the column address, row address or both are automatically counted up or down, whenever the DDRAM is accessed. And, the start point is specified by the "Window Start Column Address" and "Window Start Row Address" instructions, and the end point by the "Window End Column Address" and "Window End Row Address" instructions. For more information, refer to "(14-9) Increment/Decrement Control", "(14-25) Window End Column Address" and "(14-26)Window End Row Address". The typical sequence of the window area setting is listed below. 1. Set D2 (HV), D1 (XD) and D0 (YD) of "Increment/Decrement Control" instruction. 2. Set start point by "Window Start Column Address" and "Window Start Row Address" instructions. 3. Set end point by "Window End Column Address" and "Window End Row Address" instructions. 4. Window area is set up, and DDRAM can be accessed. NOTE) The order of address setting is column address first, then row address. Column Address Start Point (AX, AY) Row Address Window Area End Point (EX, EY) Whole DDRAM Area Fig 7 Window Area NOTE1) The following relation should be maintained to avoid malfunctions. - AX (Window Start Column Address) < EX (Window End Column Address) < Maximum Column Address - AY (Window Start Row Address) < EY (Window End Row Address) < Maximum Row Address NOTE2) The display-rotation function or the mirror-inversion function is enabled by this setting. Refer to "(4-3) DDRAM Access Direction". NOTE3)A read-modify-write operation is enabled by setting "1" at the D3 (AIM) of the "Increment/Decrement Control" instruction. Refer to the description about "AIM" bit in "(14-9) Increment/Decrement Control". Ver.2003-10-07 - 21 - NJU6815 (4-3) DDRAM Access Direction (Display-rotation and Mirror-inversion Functions) The access direction of the DDRAM is selected out of eight options by setting the D2 (HV), D1 (XD) and D0 (YD) bits of the "Increment/Decrement Control" instruction. This function allows the display data to be rotated 90, 180 or 270 degrees or mirror-inversed while being written onto the DDRAM. The following table shows the correspondences between instruction setting and on-screen image. No. HV XD YD DDRAM Access Direction (AX, AY) On-screen Image Valid Address AX < EX 0 0 0 0 AY < EY (EX, EY) (EX, EY) AX < EX 1 0 0 1 AY > EY (AX, AY) (AX, AY) AX > EX 2 0 1 0 AY < EY (EX, EY) (EX, EY) AX > EX 3 0 1 1 AY > EY (AX, AY) (AX, AY) AX < EX 4 1 0 0 AY < EY (EX, EY) (EX, EY) AX < EX 5 1 0 1 AY > EY (AX, AY) (AX, AY) AX > EX 6 1 1 0 AY < EY (EX, EY) (EX, EY) AX >EX 7 1 1 1 AY > EY (AX, AY) Fig 8 Display-rotation Function and Mirror-inverse Function NOTE1) The same display data is used for each option's on-screen image. Only difference is "HV", "XD" and "YD" bits setting. NOTE2) The following relation must be maintained to avoid malfunctions.

NJU6815 NOTE1) On the RAM MAP 2, A0, B0, C1 and C0 bits are fixed to "1". NOTE2) The functions of the variable 8-grayscale mode are different from those of the fixed 8-grayscale mode. NOTE3) The contents of the DDRAM at "C256=0" are not compatible with the contents at "C256=1". NOTE4) "C256=1" can be used in the 8-bit bus length mode, but not in the 16-bit bus length mode. NOTE5) In the 8-bit bus length mode at "C256=0", odd accesses are prohibited because display data for 1 pixel is completed in successive two accesses. NOTE6) In the 8-bit bus length mode at "C256=0", write upper bits first, then lower bits.

Then, each of the segment drivers SEGAi, SEGBi and SEGCi (i=0 to 79) generates 16 grayscales to achieve 4,096 colors. Refer to Table 12-1 and Table 12-2. (5-1-2) Variable 8-grayscale Mode Each of the palettes Aj, Bj and Cj (j=0-15) is capable of selecting 8 from 32 grayscales (0/31-31/31). 2 segment drivers of 1 RGB-group (SEGAi, SEGBi and SEGCi (i=0 to 79)) generate 8 grayscales, and the other driver does 4 grayscales to achieve 256 colors. Refer to Table 13-1 through Table 13-4. The 8-bit bus length is usually used in this mode. (5-1-3) Fixed 8-grayscale Mode The palette setting is not necessary, because the palettes Aj, Bj and Cj (j=0-15) are always fixed at 4 or 8 grayscales between 0/7 and 7/7. 2 segment drivers of 1 RGB-group (SEGAi, SEGBi and SEGCi (i=0 to 79)) are fixed at 8 grayscales, and the other driver is 4 grayscales, then results in 256 colors. Refer to Table 14-1 and Table 14-2. (5-1-4) B&W Mode The palette setting is not necessary, where the only MSB bits of display data are valid.

These clocks are used inside the LSI, and are activated by setting "1" at the D0 (SON) bit of the "Duty-1 /Display Clock ON/OFF" instruction. The CL is used for the line counter and the data latch circuit. At the rising edge of the CL signal, the line counter is counted up, then 240-bit display data is latched into the data latch circuit. At the falling edge of the CL signal, the latch data is released to the grayscale control circuit, then segment drivers Ai, Bi and Ci (i=0 to 79) produce LCD driving waveforms. The internal data-transmission timing between the DDRAM and segment drivers is completely independent of external data-transmission timing, so that MPU makes access to the LSI without concern for the LSI's internal operation. The FR and FLM are generated by the CL. The FR toggles once every frame in the default status, and is programmed to toggle once every N lines. And the FLM is used to specify an initial display line, which is preset whenever the FLM becomes "H". (8) DATA LATCH CIRCUIT The data latch circuit is used to temporarily store display data which is released to the grayscale control circuit. The display data in this circuit is updated in synchronization with the CL. The "All Pixels ON/OFF", "Display ON/OFF" and "Reverse Display ON/OFF" instructions control the data in this circuit, but does not change the data in the DDRAM. (9) COMMON DRIVERS AND SEGMENT DRIVERS The LSI includes 128-common drivers and 240-segment drivers. The common drivers generate LCD driving waveforms formed on the VLCD, V1, V4 and VSSH levels. The segment drivers generate waveforms formed on the VLCD, V2, V3 and VSSH levels.

The internal resistor is enabled by setting "0" at the D1 (CKS) bit of the "Bus Length" instruction. For more accurate frequency, using an external resistor or external clock is recommended. When using the internal resistor, the resistance is controlled to optimize frame frequency for different LCD panels, by setting the D2-D0 (RF2-RF0) bits of the "Frequency Control" instruction. For more safety, make sure what is the best frequency in the particular application. (10-1) Using Internal Resistor (CKS=0) In this case, the OSC1 should be fixed at "H" or "L" and the OSC2 is open. The oscillation frequency is varied according to the display mode, as follows. Table 16 Symbol fOSC1 fOSC2 fOSC3 Oscillation Frequency vs. Display Mode MON PWM Display Mode 0 0 Variable 8-/16-grayscale Mode 0 1 Fixed 8-grayscale Mode 1 * B&W Mode *: Don't care (10-2) Using External Resistor (CKS=1) Be sure to connect the OSC1 and OSC2 with an external resistor. The frequency of the oscillator should be adjusted to the same value generated by the internal resistor. (10-3) Using External Clock (CKS=1) Input external clock to the OSC1 and leave the OSC2 open. The external clock with 50% duty is recommended. The frequency of the external clock should be the same value generated by the internal resistor. (11) LCD POWER SUPPLY The internal LCD power supply is organized into the voltage converter and the voltage booster. The voltage converter consists of the reference voltage generator, the voltage regulator with EVR and the LCD bias voltage generator. The configuration of the LCD power supply is arranged by setting the D3 (AMPON) and D1 (DCON) bits of the "Power Control" instruction. For this configuration, the internal LCD power supply can be partially used in combination with an external supply voltage, as shown in Table 17. Table 17 DCON 0 0 1 Configuration of LCD Power Supply AMPON Voltage Booster Voltage Converter 0 Inactive Inactive 1 Inactive Active 1 Active Active External Supply Voltage VOUT, VLCD, V1, V2, V3, V4 VOUT - NOTE 1, 3, 4 2, 3, 4 - NOTE1) No internal LCD power supply is used. The LCD bias voltages are externally supplied, and the C1+, C1-, C2+, C2-, C3+, C3-, C4+, C4-, C5+, C5-, VREF, VREG and VEE are open. NOTE2) Only the voltage converter is used. The VOUT is externally supplied, and the C1+, C1-, C2+, C2-, C3+, C3-, C4+, C4-, C5+, C5- and VEE are open. The reference voltage is supplied on the VREF. NOTE3) The following relation among each LCD bias voltages must be maintained. VOUT VLCD V1 V2 V3 V4 VSSH NOTE4) If the internal LCD power supply doesn't have enough capability to drive the particular LCD panel, use the external LCD power supply. Otherwise, it may affect display quality. Ver.2003-10-07 - 37 - NJU6815 (11-1) Voltage Booster The internal voltage booster generates up to 6xVEE voltage. The boost level is selected from 2x, 3x, 4x, 5x or 6x by setting the D2-D0 (VU2-VU0) bits of the "Boost Level" instruction. The boost voltage VOUT must not exceed 18.0V, otherwise the voltage stress may cause a permanent damage to the LSI.

When using the internal LCD power supply, connect the VBA and the VREF, or supply 0.9xVEE or lower voltage on the VREF. When using an external LCD power supply, the VBA should be open. Refer to Fig 12, 14 and 15. (11-2-2) Voltage Regulator The voltage regulator consists of an operational amplifier with gain control and EVR. The VREF voltage is multiplied to obtain the VREG voltage, and its multiple (boost level) is set by the D2-D0 (VU2-VU0) bits of the "Boost Level" instruction. The formula is shown below. VREG = VREF x N (N: Boost Level) (11-2-3) Electrical Variable Resistor (EVR) The EVR is used to fine-tune the VLCD voltage to optimize display contrast. The EVR value is controlled in 128 steps by setting the D2-D0 (DV2-DV0) bits of the "EVR Control" instruction. The formula is shown below. VLCD = 0.5 x VREG + M (VREG - 0.5 x VREG) / 127 (11-2-4) LCD Bias Voltage Generator (M: EVR Value) The LCD bias voltage generator consists of buffer amplifiers and bleeder resistors to generate the LCD bias voltages such as the VLCD, V1, V2, V3 and V4, and its bias ratio is selected from 1/5, 1/6, 1/7, 1/8, 1/9, 1/10, 1/11 and 1/12. As shown in Fig 12, when using only the internal LCD power supply, the capacitors CA2 are connected to the VLCD, V1, V2, V3 and V4 respectively. As shown in Fig 13, when using no internal LCD power supply, the LCD bias voltages are externally supplied on the VLCD, V1, V2, V3 and V4, and the internal LCD power supply should be turned off by setting "0" at the "DCON" and "AMPON" bits. And the C1+, C1-, C2+, C2-, C3+, C3-, C4+, C4-, C5+, C5-, VEE, VREF and VREG are open. Fig 14 and 15 show typical peripheral circuits when partially using the LCD power supply without the reference voltage generator. Fig 16 shows the circuit when partially using the LCD power supply without the voltage booster.

The VLCD and V1-V4 are discharged by setting "1" at the D0 (DIS) bit of the "Discharge ON/OFF" instruction or the reset by the RESb. And the VOUT (100K internal resistor between VOUT and VEE) is discharged by setting "1" at the D1 (DIS2) bit of this instruction. Be sure to turned off the internal or external LCD power supply when this instruction is executed, otherwise it may function as a current load and affect an operating current. Refer to "(14-22) Discharge ON/OFF". (11-5) Power ON/OFF To protect the LSI from overcurrent, the following sequences must be maintained to turn on and off the power supply. In addition to the following discussions, refer to "(18) TYPICAL INSTRUCTION SEQUENCES". (11-5-1) Power ON/OFF in Using Internal LCD Power Supply Power ON First "VDD and VEE ON", next "Reset by RESb", then "Internal LCD power supply ON". Be sure to execute the "Display ON" instruction later than the completion of this power ON sequence. Otherwise, unexpected pixels may be turned on instantly. Power OFF First "Reset by RESb or "HALT" instruction", next "VDD and VEE OFF". If using different power sources for the VDD and the VEE individually, the VEE must be turned off after the reset or the "HALT". After that, the VDD can be turned off, waiting until the LCD bias voltages (VLCD, V1, V2, V3 and V4) drop below the threshold level of LCD pixels. (11-5-2) Power ON/OFF in Using External LCD Power Supply Power ON First "VDD and VEE ON", next "Reset by RESb", then "External LCD power supply ON". When using only external VOUT, first "VDD ON", next "Reset by RESb", then "External VOUT ON", as well. Power OFF First "Reset by RESb or "HALT" instruction" to isolate external LCD bias voltages, next "VDD OFF". For more safety, placing a resistor in series on the VLCD line (or the VOUT line in using only the external VOUT) is recommended. That resistance is usually between 50 and 100. Ver.2003-10-07 - 43 - NJU6815 (12) RESET FUNCTION The reset function initializes the LSI to the following default status by setting the RESb to "L".

Ver.2003-10-07 - 51 - NJU6815 (14) INSTRUCTION DESCRIPTIONS This chapter provides detailed descriptions about each instruction. These descriptions are written with the assumption that 80-series MPU is used. When using 68-series MPU, the polarities of the E and R/W signals differ from those of the RDb and WRb signals. (14-1) Display Data Write The "Display Data Write" instruction writes display data on a specified DDRAM address. CSb 0 RS 0 RDb 1 WRb 0 RE2 0/1 RE1 0/1 RE0 0/1 D7 D6 D5 D4 D3 Display Data D2 D1 D0 (14-2) Display Data Read The "Display Data Read" instruction reads out display data from a specified DDRAM address. One dummy read is necessary right after DDRAM address setting. CSb 0 RS 0 RDb 0 WRb 1 RE2 0/1 RE1 0/1 RE0 0/1 D7 D6 D5 D4 D3 Display Data D2 D1 D0 (14-3) Window Start Column Address The "Window Start Column Address" instruction specifies the column address of the start point. The setting order is lower byte first, then upper byte. CSb 0 RS 1 RDb 1 WRb 0 RE2 0 RE1 0 RE0 0 D7 0 D6 0 D5 D4 D3 D2 D1 D0 0 0 AX3 AX2 AX1 AX0 (Default: AX3-AX0=0H / Register Address: 0H) D5 D4 D3 D2 D1 D0 0 1 AX7 AX6 AX5 AX4 (Default: AX7-AX4=0H / Register Address: 1H) CSb 0 RS 1 RDb 1 WRb 0 RE2 0 RE1 0 RE0 0 D7 0 D6 0 (14-4) Window Start Row Address The "Window Start Row Address" instruction specifies the row address of the start point. Available setting range is from (00H) to (7FH), and outside this range is not allowed. The setting order is lower byte first, then upper byte.

During the power save, operating current is down to the stand-by level. The internal state of the LSI in the power save mode is listed below. HALT=0 HALT=1 : Power Save OFF (Normal) : Power Save ON Internal State in Power Save Mode (HALT="1") - Internal oscillator and internal LCD power supply are halted. - All segment and common drivers are fixed at VSSH level. - External clock to the OSC1 cannot be accepted. - Display data in the DDRAM is being maintained. - Data in the instruction registers are being maintained. - VLCD, V1, V2, V3 and V4 are in high impedance. NOTE) In the power save ON sequence, execute the "Display OFF" prior to the "Power Save ON". In the power save OFF sequence, execute the "Power save OFF" prior to the "Display ON". If the "Power Save ON/OFF" instruction is executed during the "Display ON", unexpected pixels may be turned on instantly.

This function allows LCD modules to work in a minimum duty cycle ratio to minimize power consumption. The partial display function is carried out by the combination of the "Duty Cycle Ratio", "LCD Bias Ratio", "Boost Level" and "EVR Control" instructions. For more information, refer to "(14-11) Duty Cycle Ratio", "(14-12) Boost Level", "(14-13) LCD Bias Ratio" and "(14-20) EVR Control". Typical setting sequence is shown in "(18-4) Partial Display Sequence". NJRC LCD DRIVER Low Power and Low Voltage Normal Fig 22 LCD DRIVER Partial Display On-screen Image in Using Partial Display Function (16) SWAP FUNCTION The swap function switches the palettes Aj and the palettes Cj (j=0-15), and is controlled by the D1 (SWAP) bit of the "Display Control (2)" instruction. This function reduces the restrictions on the IC position of an LCD module. Fig 23 "Overview of Swap Function" illustrates general outlines of internal operations, and (16-1-1) through (16-1-4) show each configuration on a mode-by-mode basis.

(17) RELATION BETWEEN ROW ADDRESS AND COMMON DRIVER The relation between row address and common driver is changed by the D3 (SHIFT) bit of the "Display Control (1)" and the "Duty Cycle Ratio", "Initial Display Line" and "Initial COM" instructions. When the "Initial Display Line" is set to (LA6:LA0=00H: Address "0"), the row address corresponding to an initial COM is "0". However, if the "Initial Display Line" is other than "0", the row address is shifted from "0" by just that address. For instance, when the initial display line address is (LA6:LA0=05H: Address "5") and the initial COM is (SC3:SC0=1H), the row address on the initial COM is "5" and the initial COM is "COM4". (17-1) through (17-5) illustrate the examples of the relation between row address and common driver.
