Read back operation is only available in parallel mode. HPM This pin is the control input of High Power Current Mode. The function of this pin is only enabled for High Power model which required special ordering. For normal models, High Power Mode is disabled and the LCD driving characteristics are the same no matter this pin is pulled High or Low. Note: This pin must be pulled to either High or Low. Leaving this pin floating is prohibited. IRS This is the input pin to enable the internal resistors network for the voltage regulator. When this pin is pulled high the internal resistors will be enalbed, and when it is low, the external resistors, R1 and R2, should be connected to VDD and VF, and VF and VL6, respectively (see application circuits). ROW0 - ROW63 These pins provide the row driving signal COM0 - COM63 to the LCD panel. See Table.1 about the COM signal mapping in different multiplex ratio N. SEG0 - SEG131 These pins provide the LCD column driving signals. Their output voltage level is VDD during sleep mode and standby mode. ICONS There are two ICONS pins (pin12 and 136) on the chip. Both pins output exactly the same signal. The reason for duplicating the pin is to enhance the flexibility of the LCD layout. NC These are the No Connection pins. Nothing should be connected to these pins, nor they are connected together. These pins should be left open individually.

SSD1815 8 REV 1.5 03/2000 SOLOMON OPERATION OF LIQUID CRYSTAL DISPLAY DRIVER Description of Block Diagram Module 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 D7-D0 is interpreted as a Command and it will be decoded and be written to the corresponding command register. MPU Parallel 6800-series Interface The parallel interface consists of 8 bi-directional data pins (D7-D0), R/W(WR), D/C, E(RD), CS1 and CS2. 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) input serves as data latch signal (clock) when high provided that CS1 and CS2 are low and high respectively. Refer to Figure 9 for Parallel Interface Timing Diagram of 6800-series microprocessors. In order to match the operating frequency of display RAM with that of the microprocessor, some 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 3 below. MPU Parallel 8080-series interface The parallel interface consists of 8 bi-directional data pins (D7-D0), E(RD), R/W(WR), D/C, CS1 and CS2. E(RD) input serves as data read latch signal (clock) when low provided that CS1 and CS2 are low and high respectively. Whether it is display data or status register read is controlled by D/C. R/W(WR) input serves as data write latch signal(clock) when high provided that CS1 and CS2 are low and high respectively. Whether it is display data or command register write is controlled by D/C. Refer to Figure 10 for Parallel Interface Timing Diagram of 8080-series microprocessor. Similar to 6800-series interface, a dummy read is also required before the first actual display data read. MPU Serial interface The serial interface consists of serial clock SCK (D6), serial data SDA (D7), D/C, CS1 and CS2. SDA is shifted into a 8-bit shift register on every rising edge of SCL in the order of D7, D6,... D0. D/C is sampled on every eighth clock to determine whether the data byte in the shift register is written to the Display Data RAM or command register at the same clock.

It takes a single supply input and generate necessary voltage levels. This block consists of: 1. 2X, 3X and 4X DC-DC voltage converter The built-in DC-DC voltage converter is use to generate large negative LCD driving voltage with reference to VDD from the voltage input (VSS1). For SSD1815, it is possible to produce 2X, 3X or 4X boosting from the protential different between VSS1 - VDD. Detail configurations of the DC-DC converter for different boosting multiples are given in Figure 6 at the right. 2. Voltage Regulator (Voltages referenced to VDD) The feedback gain control for LCD driving contrast curves can be selected by IRS pin to either internal (IRS pin = H) or external (IRS pin = L). For internal resistor network is enabled, there are eight setting can be set by software. If external control is selected, external resistors are required to be connected between VDD and VF (R1), and between VF and VL6 (R2). 3.

For SSD1815, there are 197 latches (132 + 65) for holding the data, which will be fed to the HV Buffer Cell and Level Selector to output the required voltage 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 work 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.

(1011X3X2X 1X 0)* (0001X3X2X 1X 0)* (0000X3X2X 1X 0) (X7X6X5X4X3X 2X 1X 0) Save GDDRAM Column Address by read-modify- (11100000) write mode Restore GDDRAM Column Address by end of read- (11101110) modify-write mode Note: 1. No need to resend the command again if it is set previously. 2. The read / write action to the Display Data RAM does not depend on the display mode. This means the user can change the RAM content whether the target RAM content is being displayed or not. SSD1815 16 REV 1.5 03/2000 SOLOMON Command Description Set Lower Column Address This command specifies the lower nibble of the 8-bit column address of the display data RAM. The column address will be incremented by each data access after it is pre-set by the MCU. Set Higher Column Address This command specifies the higher nibble of the 8-bit column address of the display data RAM. The column address will be incremented by each data access after it is pre-set by the MCU. Set Internal Regulator Resistors Ratio This command is to enable any one of the eight internal resistor sets for different regulator gain when using internal regulator resistor network (IRS pin pulled high). Please refer to Block Diagram Description section for detail calculation of the LCD driving voltage. Set Power Control Register This command turns on/off the various power circuits associated with the chip. Set Display Start Line This command is to set Display Start Line register to determine starting address of display RAM to be displayed by selecting a value from 0 to 63. With value equals to 0, D0 of Page 0 is mapped to COM0. With value equals to 1, D1 of Page0 is mapped to COM0. The display start line values of 0 to 63 are assigned to Page 0 to 7. Set Contrast Control Register This commands 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 used. 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/reverse display. This command will be used with " Set Display Display ON/OFF" command to form a compound command for entering power save mode. See " Set Power Save Mode" . Set Normal/Reverse Display This command sets the display to be either normal/ reverse. 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. In icon mode, the icon line is not reversed by this command. Set Display On/Off This command alternatively turns the display on and off. When display off is issued with entire display on, power save mode will be entered. See " Set Power Save Mode" for details. Set Page Address This command positions the page address from 0 to 8 possible positions in GDDRAM. Refer to Figure 5 for mapping. Set COM Output Scan Direction This command sets the scan direction of the COM output allowing layout flexibility in LCD module assembly. Set Read-Modify-Write Mode This command puts the chip in read-modify-write mode in which: 1. the column address is saved before entering the mode 2. the column address is incremented by display data write but not by display data read Software Reset This command causes some of the internal status registers of the chip to be initialized: 1. Static indicator is turned OFF 2. Display start line register is set to 0 3. Column address counter is set to 0 4. Page address is set to 0 5. Normal scan direction of the COM outputs 6. Contrast control register is set to 0 7. Test mode is turned OFF Set End of Read-Modify-Write Mode This command relieves the chip from read-modify-write mode. The column address that is saved before entering read-modify-write mode will be restored. Set Indicator On/Off This command turns on and off the static drive indicators. It also controls whether standby mode or sleep mode will be Set Segment Re-map This commands changes the mapping between the display data column address and segment driver. It allows flexibility in layout during LCD module assembly. Refer to Figure 5 for example. Set LCD Bias This command selects a suitable bias ratio (1/7 or 1/9) required for driving the particular LCD panel in use. The POR default for SSD1815 is set to 1/9 bias. For setting 1/4, 1/5, 1/6 and 1/8 bias, an extended compound command should be SOLOMON REV 1.5 03/2000 SSD1815 17 entered after the power save compound command. See " Set Power Save Mode" . When the " Set Indicator On" command is sent, the " Indicator Display Mode"must be followed in the next command. The " Set Indicator Off" command is a single byte command and no following command is required. NOP A command causing No Operation. Set Test Mode This command force the driver chip into its test mode for internal testing of the chip. Under normal operation, user should NOT use this command. Set Power Save Mode To enter Standby or Sleep Mode, it should be done by using a compound command composed of " Display ON/OFF"and Set " Set Entire Display ON/OFF"commands. When " Set Entire Display ON" is issued when display is OFF, either Standby Mode or Sleep Mode will be entered. The status of the Static Indicator will determine which power save mode is entered. If static indicator is off, the Sleep Mode will be entered: 1. Internal oscillator and LCD power supply circuits are stopped 2. Segment and Common drivers output VDD level 3. The display data and operation mode before sleep are held 4. Internal display RAM can still be accessed If the static indicator is on, the chip enters Standby Mode which is similar to sleep mode except: 1. Internal oscillator is on 2. Static drive system is on Note also that if the software reset command is issued during Standby Mode, Sleep Mode will be entered. Both power save modes can be exited by the issue of a new software command or by pulling Low at hardware pin RES. Set Bias Ratio Except the 1/4 bias, all the available bias ratios (1/5, 1/6, 1/7, 1/8 and 1/9) could be set using this command plus the Set LCD Bias. When changing the display multiplex ratio, the bias ratio also need to be adjusted to make display contrast consistent. Set Temperature Coefficient (TC) Value 4 different temperature coefficient settings is selected by this command in order to match various liquid crystal temperature grades. Modify Oscillator Frequency The oscillator frequncy can be fine tuned by applying this command. Since the oscillator frequency will be affected by some other factors, this command is not recommended for general usage. Please contact our application engineer for more detail explaination on this command. Set 1/4 Bias Ratio This command sets the bias ratio directly to 1/4 bias. This ratio is especially for use in under 12mux display. In order to restore to other bias ratio, this command must be executed, with LSB=0, before the " Set Multiplex ratio" or " Set LCD Bias"command is sent. Set Total Frame Phases The total number of phases for one display frame is set by this command. The Static Icon is generated by the overlapping of the M and MSTAT signals. To turn on the Static Icon, 3 phases overlapping will be applied to these signals, while 1 phase overlapping will be given to the Off status. The more the total number of phasesin one frame, the less the overlapping time and thus the lower the effective driving voltage at the Static Icon on the LCD panel. Set Display Offset This command should be sent ONLY when the multiplex ratio is set less than 64. When the mulitplex ratio less than 64 is set, the display will be mapped in the middle (y-direction) of the LCD, see Table 1. Use this command could move the display vertically within the 64 commons. To make the Reduced-Mux Com 0 (Com 0 after reducing the multiplex ratio) towards the Row 0 direction for L lines, the 6-bit data in second command should be given by L. To move in the other direction by L lines, the 6-bit data should be given by 64-L. Please note that the display is confined within the un-reduced 64 mux. That is maximum value of L is given by the half of 64 minus the reduced-multiplex ratio. For an odd display mux after reduction, moving away from Row 0 direction will has 1 more step. Status register Read This command is issued by pulling D/C Low during a data read (refer to Figure 9 and 10 for parallel interface waveforms). 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, on top of general ones, designed for the chip. Set Multiplex Ratio This command switches default 64 multiplex mode to any multiplex mode from 2 to 64. The chip pads ROW0-ROW63 will be switched to corresponding COM signal output, see Table 1 for examples of different multiplex settings.
