When the pin is low, initialization of the chip is executed. PS0, PS1 PS0 and PS1 determine the interface protocol between the driver and MCU. Refer to the following table for details. PS0 L L H H PS1 L H L H Interface 3-wire SPI (write only) 4-wire SPI (write only) 8080 parallel interface (read and write allowed) 6800 parallel interface (read and write allowed) CS This pin is chip select input. The chip is enabled for display data/command transfer only when CS is low. D/ C This input pin is to identify display data/command cycle. When the pin is high, the data written to the driver will be written into display RAM. When the pin is low, the data will be interpreted as command. This pin must be connected to VSS when 3-lines SPI interface is used. R/ W ( WR ) This pin is microprocessor interface signal. When 6800 interface mode is selected (by PS0 and PS1), the signal indicates read mode when high and write mode when low. When 8080 interface mode is selected (by PS0 and PS1), a data write operation is initiated when R/ W( WR ) is low and the chip is selected. E( RD ) This pin is microprocessor interface signal. When 6800 interface mode is selected (by PS0 and PS1), a data operation is initiated when E( RD ) is high and the chip is selected. When 8080 interface mode is selected (PS0 and PS1), a data read operation is initiated when E( RD ) is low and the chip is selected. D0-D7 These pins are 8-bit bi-directional data/command bus to be connected to the microprocessor’s data bus. When serial mode is selected, D7 is the serial data input SDA and D6 is the serial clock input SCK. INTRS This pin is an input pin to enable the internal resistor network for the voltage regulator when INTRS is high. When external regulator is used, this pin must be connected to VSS, and external resistor R1/R2 should be connected to VL6, VR and VSS. REF This pin is an input pin to enable the internal reference voltage used for the internal regulator. When it is high, an internal reference voltage source will be used. When it is low, an external reference voltage source must be provided to VEXT pin if internal regulator is used. VDD Power supply pin. SSD1850/51 Series Rev 1.2 01/2003 11 SOLOMON VSS Ground. VCI Reference voltage input for internal DC-DC converter. The voltage of generated VCC equals to the multiple factor (2X, 3X, 4X, 5X or 6X) times VCI with respect to VSS. Note: voltage at this input pin must be larger than or equal to VDD. 6x is available for SSD1851 only. VCC This is the most positive voltage supply pin of the chip. It can be supplied externally or generated by the internal DC-DC converter. When using internal DC-DC converter as generator, voltage at this pin is for internal reference only. It CANNOT be used for driving external circuitries. C1P, C2P, C3P, C4P, C5P, C1N and C2N When internal DC-DC voltage converter is used, external capacitor(s) is/are connected to these pins. (Reference to application Circuit on P.42) VL6 This pin is the most positive LCD driving voltage. It can be supplied externally or generated by the internal regulator. VR This pin is an input of the internal voltage regulator. When the internal resistors network for the voltage regulator is disabled (INTRS is pulled low), external resistors should be connected between VSS and VR, and VR and VL6, respectively (Please refer to application circuit on P.43). VEXT This pin is an input to provide an external voltage reference for the internal voltage regulator when REF pin is pulled L. VL5, VL4, VL3 and VL2 These are LCD driving voltages. They can be supplied externally or generated by the internal bias divider. They have the following relationship: VL6 > VL5 > VL4 > VL3 > VL2 > VSS 1:a bias VL5 (a-1)/a*VL6 VL4 (a-2)/a*VL6 VL3 2/a*VL6 VL2 1/a*VL6 For SSD1851, “a” equals to 10 at POR. For SSD1850, “a” equals to 9 at POR. COM0 - COM79 These pins provide the row driving signal COM0 - COM79 to the LCD panel. ICONS This pin is the special icon line COM signal output. 12 SSD1850/51 Series Rev 1.2 01/2003 SOLOMON SEG0 - SEG127 These pins provide the LCD column driving signal. Their voltage level is VSS during sleep mode and standby mode. S5150 For SSD1851, this pin must be connected to VSS. For SSD1850, this pin must be connected to VDD. CL This pin is the external clock input for the device if external clock mode is selected by software command. Under POR operation, this pin should be left opened and internal oscillator will be used after power on reset. N/C These No Connection pins should NOT be connected to any signal pins nor shorted together. They should be left open. SSD1850/51 Series Rev 1.2 01/2003 13 SOLOMON FUNCTIONAL BLOCK DESCRIPTIONS Command Decoder and Command Interface This module determines whether the input data is interpreted as data or command. Data is directed to this module based upon the input of the D/ C pin. If D/ C is high, data is written to Graphic Display Data RAM (GDDRAM). If D/ C is low, the input at D0-D7 is interpreted as a Command and it will be decoded and written to the corresponding command register. Reset is of the same function as Power ON Reset (POR). Once RES receives a negative reset pulse of about 1us, all internal circuitry will be back to its initial status. Refer to Command Description section for more information. MPU Parallel 6800-series Interface The parallel interface consists of 8 bi-directional data pins (D0-D7), R/ W( WR ), D/ C , E( RD ) and CS . R/ W( WR ) input High indicates a read operation from the Graphic Display Data RAM (GDDRAM) or the status register. R/ W( WR ) input Low indicates a write operation to Display Data RAM or Internal Command Registers depending on the status of D/ C input. The E( RD ) and CS input serves as data latch signal (clock) when they are high and low respectively. Refer to P.35, Figure 1 of parallel timing characteristics for Parallel Interface Timing Diagram of 6800-series microprocessors. In order to match the operating frequency of display RAM with that of the microprocessor, pipeline processing is internally performed which requires the insertion of a dummy read before the first actual display data read. This is shown in Figure 4 below. R/ W( WR ) E( RD ) Data bus N write column address n dummy read data read1 n+1 data read 2 n+2 data read 3 Figure 4 - display data read with the insertion of dummy read MPU Parallel 8080-series interface The parallel interface consists of 8 bi-directional data pins (D0-D7), R/ W( WR ), E( RD ), D/ C and CS . The CS input serves as data latch signal (clock) when it is low. Whether it is display data or status register read is controlled by D/ C . R/ W( WR ) and E( RD ) input indicate a write or read cycle when CS is low. Refer to P.37, Figure 2 of parallel timing characteristics for Parallel Interface Timing Diagram of 8080series microprocessor. Similar to 6800-series interface, a dummy read is also required before the first actual display data read. 14 SSD1850/51 Series Rev 1.2 01/2003 SOLOMON MPU Serial 4-wire Interface The serial interface consists of serial clock SCK, serial data SDA, D/ C and CS . Input to SDA is shifted into a 8-bit shift register on every rising edge of SCK in the order of D7, D6,...D0. D/ C is sampled on every eighth clock and the content in the shift register is written to the Display Data RAM or command register in the same clock. No extra clock or command is required to end the transmission. MPU Serial 3-wire Interface Operation is similar to 4-wire serial interface except D/ C is not used. The Set Display Data Length command is used to indicate that a specified number display data byte (1-256) is to be transmitted. Next byte after the display data string is handled as a command. It should be noted that if there is a signal glitch at SCK that causing an out of synchronization in the serial communication, a hardware reset pulse at RES pin is required to initialize the chip for re-synchronization. Modes of operation Data Read Data Write Command Read Command Write 6800 parallel Yes Yes Status only Yes 8080 parallel Yes Yes Status only Yes Serial No Yes No Yes Graphic Display Data RAM (GDDRAM) The GDDRAM is a bit mapped static RAM holding the bit pattern to be displayed. The size of the RAM is 128 x 81 x 2 = 20736bits. Figure 5 is a description of the GDDRAM address map. For mechanical flexibility, remapping on both Segment and Common outputs are provided respectively. For vertical scrolling of display, an internal register storing the display start line can be set to control the portion of the RAM data to be mapped to the display.

The oscillator generates the clock for the DC-DC voltage converter. This clock is also used in the Display Timing Generator. Oscillator enable enable enable Oscillation Circuit Buffer (CL) Internal Internal pwellresistor resistor OSC1 OSC2 Figure 6. Oscillator Circuitry LCD Driving Voltage Generator and Regulator This module generates the LCD voltage needed for display output. It takes a single supply input and generates necessary bias voltages. It consists of: 1. 2X, 3X, 4X, 5X and 6X DC-DC voltage converter *Note: SSD1850 works up to 5X only. Please refer to application notes on P.42. 2. Voltage Regulator Feedback gain control for initial LCD voltage. External resistors are connected between VSS and VR, and between VR and VL6. These resistors are chosen to give the desired VL6 according to the following equations: R VL 6 = 1 + 2 * Vcon * G R1 63 − α Vcon = 1 − * Vref 210 where Vref is the internally generated reference voltage with a known R1 and R2. Typical value for Vref is 2.1V R1 is the resistance of the resistor between VSS and VR. R2 is the resistance of the resistors between VR and VL6. α is the software contrast level from 0 to 63. G = 1 if INTRS = VDD; REF = VDD G = 0.80 if INTRS = VSS; REF = VDD 18 SSD1850/51 Series Rev 1.2 01/2003 SOLOMON 3. Bias Divider If the output op-amp buffer option in Set Power Control Register command is enabled, this circuit block will divide the regulator output (VL6) to give the LCD driving levels (VL2 -VL5). A low power consumption circuit design in this bias divider saves most of the display current comparing to traditional design. Stabilizing Capacitors (0.47~2uF) are required to be connected between these voltage level pins (VL2 VL5) and VSS. If the LCD panel loading is heavy, four additional resistors are suggested to add to the application circuit as following: VSS VL2 VL3 VL4 VL5 VL6 RL RL Remarks: 1. C2 = 0.47~2.0uF 2. RL = 100K~1M (Optional) RL RL + VSS + + C2 C2 + C2 + C2 C2 Connections for heavy loading applications 4. Contrast Control Software control of 64 voltage levels of LCD voltage. 5. Bias Ratio Selection circuitry Software control of 1/4 to 1/10 bias ratio to match the characteristic of LCD panel. Note: SSD1850 has 1/4 to 1/9 bias only. 6. Self adjust temperature compensation circuitry Provide 2 different temperature compensation grade selections to satisfy the various liquid crystal temperature grades. The grading can be selected by software control. Default temperature coefficient (TC) value is -0.05%/°C. 193 / 209 Bit Latch A register carries the display signal information. In 128X65/81 display mode, data will be fed to the HVbuffer Cell and level-shifted to the required level. Level Selector Level Selector is a control of the display synchronization. Display voltage can be separated into two sets and used with different cycles. Synchronization is important since it selects the required LCD voltage level to the HV Buffer Cell, which in turn outputs the COM or SEG LCD waveform. HV Buffer Cell (Level Shifter) HV Buffer Cell works as a level shifter which translates the low voltage output signal to the required driving voltage. The output is shifted out with an internal FRM clock which comes from the Display Timing Generator. The voltage levels are given by the level selector which is synchronized with the internal M signal.

Set Normal/Inverse Display This command sets the display to be either normal/inverse. In normal display, a RAM data of 1 indicates an “ON” pixel. While in reverse display, a RAM data of 0 indicates an “ON” pixel. The icon line is not affected by this command. Set Entire Display On/Off This command forces the entire display, including the icon row, to be “ON” regardless of the contents of the display data RAM. This command has priority over normal/inverse display. To execute this command, Set Display On command must be sent in advance. Set LCD Bias This command is used to select a suitable bias ratio (1/4 to 1/11) required for driving the particular LCD panel in use. The POR default for SSD1851 is set to 1/10 bias and SSD1850 is set to 1/9. Software Reset This command causes some of the internal status of the chip to be initialized: 1. Page address is set to 0 2. Column address is set to 0 3. Initial Display Line is set to 0 (point to display RAM page 0, D0) 4. Internal Resistor Ratio register is set to (0,0,0) 5. Software Contrast is set to 32 Set COM Output Scan Direction This command sets the scan direction of the COM output allowing layout flexibility in LCD module assembly. 28 SSD1850/51 Series Rev 1.2 01/2003 SOLOMON Set Power Control Register This command turns on/off the various power circuits associated with the chip. Set Internal Regulator Resistors Ratio This command is to enable any one of the eight internal resistor (IRS) settings for different regulator gains when using internal regulator resistor network (INTRS pin pulled high). The Contrast Control Voltage Range curves is given in the figure below: Set Contrast Control Register This command adjusts the contrast of the LCD panel by changing VL6 of the LCD drive voltage provided by the On-Chip power circuits. VL6 is set with 64 steps (6-bit) contrast control register. It is a compound commands: Set Contrast Control Register Contrast Level Data No Changes Complete? Yes Set Display Offset The next command specifies the mapping of display start line (COM0 if display start line register equals to 0) to one of ROW0-79. This command has no effect on ICONS. COM0 is mapped to ROW0 after reset. SSD1850/51 Series Rev 1.2 01/2003 29 SOLOMON Set Multiplex Ratio This command switches default 80 multiplex mode to any multiplex from 16 to 80, if Icon is disabled (POR). When Icon is set enable, the corresponding multiplex ratio setting will be mapped to 17 to 81. The chip pads ROW0-ROW79 will be switched to corresponding COM signal output. Set Power Save Mode This command forces the chip to enter Standby or Sleep Mode. LSB of the command will define which mode will be entered. Exit Power Save Mode This command releases the chip from either Standby or Sleep Mode and return to normal operation. Set N-line Inversion Number of line inversion is set by this command for reducing crosstalk. 3 to 33-line inversion operations could be selected. At POR, this operation is disabled. It should be noted that the total number of mux (including the icon line) should NOT be a multiple of the inversion number (N). Or else, some lines will not be changed their polarity during frame change. Exit N-line Inversion This command releases the chip from N-line inversion mode. The driving waveform will be inverted once per frame after issuing this command. Set DC-DC Converter Factor Internal DC-DC converter factor is set by this command. For SSD1850, 2X to 5X multiplying factors could be selected. 2X/3X, 4X, 5X and 6X factors are selected using this command. Hardware configuration is used for 2X or 3X setup. For SSD1851, 2X to 6X multiplying factors could be selected. Set Icon Enable This command enable/disable the Icon display. Start Internal Oscillator After POR, the internal oscillator is OFF. It should be turned ON by sending this command to the chip. Set Display Data Length This two-byte command only valid when 3-wire SPI configuration is set by H/W input (PS0=PS1=L). The second 8-bit is used to indicate that a specified number display data byte (1-256) are to be transmitted. Next byte after the display data string is handled as a command. Set Gray Scale Mode (White/Light Gray/Dark Gray/Black) Command 88(hex) to 8F(hex) are used to specify the four gray levels’ pulse width at the four possible frames. The four gray levels are called white, light gray, dark gray and black. Each level is defined by 4 st registers for 4 consecutive frames. For example, WA is a 4-bit register to define the pulse width of the 1 nd frame in White mode. WB is a register for 2 frame in White mode etc. Each command specifies two registers. 30 SSD1850/51 Series Rev 1.2 01/2003 SOLOMON For 4 FRC, Memory Content st nd 1 Byte 2 Byte 0 0 1 1 0 1 0 1 Gray Mode White Light Gray Dark Gray Black FRAME 1 st WA LA DA BA 2 nd 3 WB LB DB BB rd 4 WC LC DC BC th WD LD DD BD For 3 FRC, Memory Content st nd 1 Byte 2 Byte 0 0 1 1 0 1 0 1 Gray Mode White Light Gray Dark Gray Black FRAME 1 st WA LA DA BA 2 nd WB LB DB BB 3 rd WC LC DC BC th 4 (No use) WD (XX) LD (XX) DC (XX) BC (XX) Set PWM and FRC This command selects the number of frames in frame rate control, or the number of levels in the pulse width modulation. Set Test Mode This command forces the driver chip into its test mode for internal testing of the chip. Under normal operation, user should NOT use this command. Status Register Read This command is issued by setting D/ C Low during a data read (refer to figure 1 and 2 parallel interface waveform, P.35-38). It allows the MCU to monitor the internal status of the chip. No status read is provided for serial mode. EXTENDED COMMANDS These commands are used, in addition to basic commands, to trigger the enhanced features designed for the chip. These features are on top of general ones. Set VL6 noise reduction This command is to enable the VL6 noise reduction. This command is only valid for the IC version with G prefix notation on the “DTE” (datecode) field of label printed on die tray cover, intermediates and outer boxes. For details, please refer to the product change notification document of PC0010 from SSL. Set Temperature Coefficient (TC) Value This command is to set 1 out of 2 different temperature coefficients in order to match various liquid crystal temperature grades. Select Oscillator Source This command enables the external clock input from CL pin. Oscillator adjustment This command is used to adjust the oscillator frequency to desired frame frequency. Lock/Unlock Interface After sending the lock command, the interface will be disabled until the unlock command is received. The lock command is suggested whenever the LCD driver will not be accessed for some period. This can minimize incorrect data or command written due to noisy interface.
