DESCRIPTION 2. FEATURES S1D15G00 series are the LCD drivers equipped with the liquid crystal drive power circuit to realize color display with one chip. S1D15G00 can be directly connected to the MPU bus to store parallel or serial gray-scale display data from MPU on the built-in RAM and to generate liquid crystal drive signals independent from MPU. S1D15G00 generates 396 segment outputs and 160*1 common outputs for driving liquid crystal. It incorporates the display RAM with capacity of 396 × 168 × 4 (16 grayscale). A single dot of pixel on the liquid crystal panel corresponds to 4 bits of the built-in RAM, enabling to display 132 (RGB) × 160 pixels with one chip. Read or write operations from MPU to the display RAM can be performed without resorting to external actuating clock signals. S1D15G00 allows you to run the display system of high performance and handy equipment at the minimum power consumption thanks to its low-power liquid crystal drive power circuit and oscillation circuit. *1 : The S1D15G00D10*100 generates 300 segment outputs and 120 common outputs. It incorporates the display RAM with 300 × 168 × 4 capacity and displays 100 (RGB) × 120 pixels. • Number of liquid crystal-drive outputs: 396 segment outputs and 160 common outputs. • Low cross talk by frame rate modulation. • 256 color from 4096-color display or full 4096-color display. When 256 color from 4096-color display is selected: 8 gray-scale for red and green and 4 gray-scale for blue (intermediate tone is selected with the command). When 4096-color display is selected: 16 gray-scale for red, green and blue. • Direct data display with display RAM (When the LCD is set to normally black) RAM bit Data “0000” ... OFF (Black) “1111” ...ON (Maximum RGB display) (Normally black LCD, using "inverse display" command) • Partial display function: You can save power by limiting the display space. This function is most suited for handy equipment in the standby mode. • Display RAM : 396 × 168 × 4 = 266,112 bits.*1 *1: The S1D15G00D10*000 has RAM of 300 × 120 × 4 = 144,000 bits. • MPU interface: S1D15G00 can be directly connected to both of the 8/16-bit parallel 80 and 68 series MPU. Two type serial interface are also available. • 3 pins serial : CS, SCL and SI (D/C + 8-bit data) • 4 pins serial : CS, SCL, SI and A0 • Abundant command functions: Area scroll function, automatic page & column increment function, display direction switching function and power circuit control function. • Built-in liquid crystal drive power circuit: S1D15G00 is equipped the charge pump booster circuit, voltage follower circuit and electric volume control circuit. • Oscillation circuit with built-in high precision CR (external clock signals acceptable) • EEPROM interface functions • Low current consumption 500µA (Conditions: S1D15G00D01B100, VDD = VDDI = 3.0V, frame frequency 130Hz, V2 = 6.0V, all display RAM data is “0”) • Supply voltage Power for input/output system power: VDDI–GND=1.7V to 3.6V Power for internal circuit operation: VDD–GND=2.6V to 3.6V Reference power for booster circuit: VDD2–GND=2.6V to 3.6V Power for liquid crystal drive: V3–MV3 =12.0V to 21.0V • Wider operational range: –40°C to 85°C. • Shipping from: Chip with gold bump.

Except when the CS=LOW is taking place, D15 to D0 on S1D15G00 are caused to high impedance, disabling input of A0, RD (E) and WR (R/W). Relation between Data Bus and Gradation Data S1D15G00 offers the 256-color display (8 gray-scale) out of 4096 colors as well as the 4096-color display (16 grayscale). When using 256-color display out of 4096 colors, you can specify color for each of R, G and B using the palette function. (1) 256-color display out of 4096 colors Using RGBSET8 command enables you to set color for each of R, G and B by turning on the palette function prepared to convert 3- or 2-bit data to 4-bit data. 1 8-bit mode D7, D6, D5, D4, D3, D2, D1, D0: RRRGGGBB (8 bits) data is converted to RRRRGGGGBBBB (12 bits) and then stored on the display RAM. 2 16-bit mode D15, D14, D13, D12, D11, D10, D9, D8: RRRGGGBB (8 bits) D7, D6, D5, D4, D3, D2, D1, D0: RRRGGGBB (8 bits) Data of two pixels is respectively converted to RRRRGGGGBBBB (12 bits) data and then simultaneously written to two addresses on the display RAM.

Meanwhile, the 9-bit serial interface uses three pins - CS, SI and SCL - for the same purpose. Data read is not available with the serial interface. Data entered must be 8 bits. Refer to the following chart for entering commands, parameters or gray-scale data. The relation between gray-scale data and data bus in the serial input is the same as that in the 8-bit parallel interface mode (described in the preceding section) at every gradation.

Before entering succeeding sets of data, you must correctly input the data concerned again. * In order to avoid data transfer error due to incoming noise, it is recommended to set CS at HIGH on byte basis to initialize the serial-to-parallel conversion counter and the register. Rev. 1.0 EPSON 13 S1D15G00 Series 8.2 Access to DDRAM and Internal Registers S1G15G00 realizes high-speed data transfer because the access from MPU is a sort of pipeline processing done via the bus holder attached to the internal, requiring the cycle time alone without needing the wait time. For example, when MPU writes data to the DDRAM, the data is once held by the bus holder and then written to the DDRAM before the succeeding write cycle is started. When MPU reads data from the DDRAM, the first read cycle is dummy and the data read in the dummy cycle is held by the bus holder, and then it is read from the bus holder to the system bus in the succeeding read cycle. Fig. 8.2.1 illustrates these relations. * Write operation A0 tcyc WR Command write MPU Data write Data write DATA Bus holder Internal Data write signal * Read operation A0 Command write WR Dummy read Data read RD MPU External pulse Bus holder Command RAM data RAM data Internal Data Read signal Fig. 8.2.1 * There is a restriction in the read sequence of the DDRAM. Namely, the data at the specified address is not output in the first data read conducted immediately after the memory read command (dummy read). It is read in the second data read. 14 EPSON Rev. 1.0 S1D15G00 Series 8.3 DDRAM 8.3.1 DDRAM It is 396 × 168 × 4 bits capacity RAM prepared for storing dot data. You can access a desired bit by specifying the page address and column address. Since display data from MPU - D7 to D0 and D1 to D8 - correspond to one or two pixels of RGB, data transfer-related restrictions are reduced, realizing the display flexibly. The RAM on S1D15G00 is separated to a block per 4 line to allow the display system to process data on the block basis. MPU’s read and write operations to and from the RAM are performed via the I/O buffer circuit. Reading of the RAM for the liquid crystal drive is controlled from another separate circuit. Refer to the following memory map for the RAM configuration. 1Models other than the S1D15G00D10*100 (models that have 132 RGB × 160 output) Memory Map (When using the 8 gray-scale. 8-bit mode) RGB alignment (Command of data control parameter2=000) Column LCD read direction P11:0 0 1 131 P11:1 131 132 0 Color Page Block 0 1 2 40 41 SEGout P10:0 R G B R G B R G B Data D7 D6 D4 D3 D1 D0 D7 D6 D4 D3 D1 D0 D7 D6 D4 D3 D1 D0 P10:1 D5 D2 D5 D2 D5 D2 1 2 4 5 394 395 0 167 1 166 2 165 3 164 4 163 5 162 6 161 7 160 8 159 9 158 160 7 161 6 162 5 163 4 164 3 165 2 166 1 167 0 3 6 396 Each of RGB data entered to D7 to D0 (3 or 2 bits) is converted to 4 bits before written to the RAM.

You can specify a scope of the page address (start and end page) with PASET (page address set) command. When the page-direction scan is specified with DATCTL (data control) command and the addresses are incremented from the start up to the end page, the column address is incremented by 1 and the page address returns to the start page. The DDRAM supports up to 168 lines*1, and thus the total page becomes 168. *1: S1D15G00D10*000 supports up to 120 lines and the total number of pages is 120. In the read operation, as the end page is reached, the column address is automatically incremented by 1 and the page address is returned to the start page. Using the address normal/inverse parameter of DATCTL command allows you to inverse the correspondence between the DDRAM address and common output. 8.3.3 Column Address Control Circuit This circuit is used to control the address in the column direction when MPU accesses the DDRAM. You can specify a scope of the column address (start and end column) using CASET (column address set). When the column-direction scan is specified with DATCTL command and the addresses are incremented from the start to the end up to the end column, the page address is incremented by 1 and the column address returns to the start column. In the read operation, too, the column address is automatically incremented by 1 and returns to the start page as the end column is reached. Just like the page address control circuit, using the column address normal/inverse parameter of DATCTL command enables to inverse the correspondence between the DDRAM column address and segment output. This arrangement relaxes restrictions in the chip layout on the LCD module. 8.3.4 I/O Buffer Circuit It is the bi-directional buffer used when MPU reads or writes the DDRAM. Since MPU’s read or write of the DDRAM is performed independently from data output to the display data latch circuit, asynchronous access to the DDRAM while the LCD is turned on does not cause troubles such as flicking of the display images. 8.3.5 Block Address Circuit This circuit associates pages on the DDRAM with COM output. S1D15G00 processes signals for the liquid crystal display on 4-page basis (block basis). Thus, when specifying a specific area in the area scroll display or partial display, you must designate it in block. 8.3.6 Display Data Latch Circuit This circuit is used to temporarily hold display data to be output from the DDRAM to the SEG decoder circuit. Since DISNOR/DISINV (display normal/inverse) and DISON/DISOFF (display on/display off) commands are used to control data in the latch circuit alone, they do not modify data in the DDRAM. Rev. 1.0 EPSON 23 S1D15G00 Series 8.4 Area Scroll Display Using ASCSET (area scroll set) and SCSTART (scroll start set) commands allows you to scroll the display screen partially. You can select any one of the following four scroll patterns. Center screen scroll : Fixed area Top screen scroll Bottom screen scroll Whole screen scroll : Scroll area Fig. 8.4.1 When, for example, 1/128 duty (Display area: 32 blocks = 128 lines) is selected, and the top 2 blocks = 8 lines and bottom 2 blocks = 8 lines are specified as the fixed areas and the remaining 28 blocks = 112 lines as the scroll area, 10 blocks = 40 lines on the DDRAM can be used as the background area. DDRAM block LCD panel 0 1 2 32 blocks =128 line 29 30 39 Fixed area 40 Display area Scroll area 41 Background area 24 EPSON Rev. 1.0 S1D15G00 Series 8.5 Partial Display Using PTLIN (partial in) command allows you to turn on the partial display (division by line) of the screen. This mode requires less current consumption than the whole screen display, making it suitable for the mobile equipment in the standby state. : Display area (partial display area) : Non-display area 8.6 Gray-Scale Display This function represents gray-scale by frame modulating the gray-scale date written on the display data RAM. In the 256-out-of-4096 colors (8 gray-scale) display, you can specify display colors using the command. Normally black liquid crystal in the reverse display mode - 8 gray scale display R (D7,D6,D5) Black (0,0,0) Red G (D4,D3,D2) Black (0,0,0) (0,0,1) (0,1,0) (0,1,1) (1,0,0) (1,0,1) (1,1,0) (1,1,1) B (D1,D0) Black (0,0) (0,1) (0,1) (0,1) (1,0) (1,0) (1,0) (1,1) (0,0,1) (0,1,0) (0,1,1) (1,0,0) (1,0,1) (1,1,0) (1,1,1) Green Blue Any one of above Any one of above Respective data on red, green and blue are converted to the display data to be specified by the parameters of RGBSET8 command, and then written to the DDRAM. Blue is displayed in 4 gray-scale. 8.7 Oscillation Circuit S1G15G00 contains the oscillation circuit whose operation does not require any external part. The oscillation circuit is enabled only when M/S = HIGH and CLS = HIGH. When the external clock signal is (CLS = LOW or M/S = LOW), the clock is entered from CL pin. 8.8 Display Timing Generation Circuit This circuit generates the timing signal for display (CL, FR, SYNC, CA, F1, F2, DOFF) using the clock from the builtin oscillation circuit or the external clock. It is also used to generate the clock to turn on the liquid crystal-drive power circuit. When using S1D15G00 in multi-chip array, the display timing signal (CL, FR, SYNC, CA, F1, F2, DOFF) must be sent from the master to the slave. 8.9 SEG Decoder Circuit This circuit outputs the segment driver control signal based on display data for 4-page and the timing signal. 8.10 Liquid Crystal Drive Circuit It outputs liquid crystal drive voltage. Responding to the decoder output signal and the display-timing signal, the segment output pin outputs one of potentials V2, V1 , VC, MV1 or MV2 and the common output pin outputs one of potentials V3, VC or MV3. Rev. 1.0 EPSON 25 S1D15G00 Series 8.11 Liquid Crystal-Drive Power Circuit The power circuit contained in S1D15G00 generates voltage required to drive liquid crystal. This low power consumption type power circuit is consisted the voltage regulator, booster circuits (primary, secondary) and voltage follower. The power circuit is enabled only when the master operation mode is turned on. The power control circuit turns on or off the voltage regulator, booster circuits, Reference voltage generation circuit and voltage follower responding to PWRCTR (power control set) command. Thus, function of the external and internal power supplies can be partly used in parallel. Table 8.11.1 lists the functions controlled by the 4-bit data - parameter of PWRCTR.

VDD2-GND voltage is tripled by capacitor C connected across CAP1+ and CAP1,CAP2+ and CAP2- as well as VCSL and GND (or VDD2), and then output at V CSL pin. In the case of double boosting, short circuit the CAP2+ and VCSL pin. Fig. 8.11.2 shows how the voltage is stepped up by the capacitors connected.

S1D15G00 incorporates the high-precision constant voltage source, 64-step electronic volume control function and resistor to regulate V2 voltage. The voltage regulator circuit covers a wider temperature range with fewer numbers of parts thanks to the temperature gradient control function as well as the temperature sensing function. However, capacitors may be required for voltage regulation between V2 and GND pins due to the load of LCD panel. Insert the capacitors, if necessary, by observing the voltage waveforms and current consumption. 1 Built-in Resistor for V2 Voltage Regulation The contents described in this document apply only to models that use a V2 voltage control resistor inside the IC. Using this resistor and the electronic volume control function allows you to control the liquid crystal drive voltage V2 to an optimum level for the LCD panel with the command alone, without resorting to external resistors. V2 output voltage can be determined from Equation A-1 as long as the relation V 2 < VCSL is met. However, set the voltage of V2 by allowing for a drop in the voltage due to load, so that it becomes at or below 80 % of VCSL.

Enter the power supply control command first, then wait at least 100ms before entering the display ON command when the built-in power supply circuit operates. If you do not wait, an unwanted display may appear on the liquid crystal panel. Display ON (DISON): Display OFF *1: When the IC is in Sleep In state, the liquid crystal drive power supply and the boosting power output and GND pin are jumpered, therefore, the Sleep Out command must be entered to cancel the Sleep state prior to turning on the built-in circuit. (Note) If changes are unnecessary after resetting, command input is unnecessary. Rev. 1.0 EPSON 55 S1D15G00 Series 12.2.2 Command Input Procedure During Power Off •When power-on reset is not used << IC status>> Display off (DISOFF): display is turned off, and all of the common and segment pins become VC potential. Liquid crystal drive power supply circuit off (PWRCTR): built-in power supply circuit stops. Oscillation off (OSCOFF): built-in oscillation circuit stops and all the circuits inside the IC also stop. Sleep In (SLPIN) *2 Stop the power supply (VDDI, VDD). *2: In order to discharge the capacitor connected to the liquid crystal drive power supply circuit, execute the Sleep In command to put the IC in Sleep state prior to stopping the power supply. Stop VDDI and VDD when the output of the liquid crystal drive power supply circuit has dropped sufficiently. •When power-on reset is used Turn on the power-on reset (RES = LOW) *3 Stop the power supply (VDDI , VDD). *3: Stop VDDI and VDD when the output of the liquid crystal drive power supply circuit has dropped sufficiently. (Note) This IC is the logic circuit of the VDD-GND and VDDI-GND power supplies, and it controls the liquid crystal output driver. If the VDDI-GND and VDD-GND power supplies are stopped with residual voltage in the liquid crystal drive power supply circuit, the liquid crystal output driver (COM, SEG) may output uncontrolled voltage. Stop VDDI and VDD when the output of the liquid crystal drive power supply circuit has dropped sufficiently. 12.2.3 Sleep state This IC goes into Sleep state when the Sleep In command and several other commands are executed. When in the Sleep state, IC power consumption will be kept to a minimum. Also, internal status including the display RAM will be maintained, the Sleep Out and several commands will resume the display state. •Setting the Sleep state << IC status>> 1 Display off (DISOFF): display is turned off, and all the common segment and pins become VC potential. 2 Liquid crystal drive power supply circuit off (PWRCTR): built-in power supply circuit stops. 3 Oscillation off (OSCOFF): built-in oscillation circuit stops and all the circuits inside the IC also stop. Sleep In (SLPIN): commands other than 1 to 3 and display RAM content are maintained. Commands can be entered. •Releasing the Sleep state <<IC status>> Sleep Out (SLPOUT) Oscillation on (OSCON): built-in power supply circuit operates and liquid crystal drive potential is supplied. Wait (approx. 100ms): wait until liquid crystal drive power supply boots and stabilizes. Wait until the power supply voltage stabilizes. Display on (DISON): display comes on and the display RAM content is output. 56 EPSON Rev. 1.0 S1D15G00 Series 12.2.4 Refresh Sequence Refreshing of the state setup is recommended by reentering the command parameters and the display data in order to recover from improper IC operations due to such reasons as noise. Reconfigure the following commands and parameters. Common scan direction (COMSCN) Oscillation on (OSCON) Sleep Out (SLPOUT) Electronic volume control (VOLCTR) Temperature gradient (TMPGRD) Power supply control (PWRCTR) Normal (DISNOR)/Inverted display (DISINV) Partial in (PTLIN)/Partial out (PTLOUT) Area scroll set (ASCSET) Scroll start set (SCSTART) Data control (DATCTL) 256-color position set (RGBSET8) NOP instruction (NOP) *1 Page address set (PASET) Column address set (CASET) Memory write command (RAMWR): display data write Display on (DISON) *1: IC shipment inspection test state can be escaped with NOP instruction. Add this to the refresh sequence. If display control (DISCTL) is reconfigured during display, noise may occur on the display, so omit this from the refresh sequence. Reconfigure with the display off.

EEPROM INTERFACE The S1D15G00D00* 100 and S1D15G00D05* 100 series chips provide the Write and Read functions to write the Electronic Control value and built-in resistance ratio into and read them from the peripheral EEPROM (S1F65170). Using the Write and Read functions, you can store these values appropriate to each LCP panel. Notes: As the EPCTIN, EPCWR and EPCRD commands require the following processing times, use a software timer or insert a process to loop the operation by monitoring the status read value of D2 (Access to EEPROM). If these times are insufficient, the Read or Write operation may fail. 14.1 Conditions when EEPROM read/write is performed 1 EPCTIN 5 (sec) fosc / 4 1 The built-in oscillator circuit is already operating. 2 The CL division by 2 and 160 display lines have been set by the Display Control command. 2 EPCWR 10 (sec) fosc / 320 3 EPCRD 10 (sec) fosc / 4 14.2 EEPROM writing instructions 1. Issue the VOLCTR command to set the appropriate Electronic Control value and built-in resistance ratio. 2. Issue the EPCTIN command to select the Control EEPROM mode (for data writing). 3. Issue the EPMWR command to write data into the EEPROM. 4. Issue the EPCTOUT command to cancel the EEPROM Control mode. 14.4 Connection example S1D15G00 and S1F65170 connection example. VDD for both chips is connected to the same potential. 14.3 EEPROM data reading instructions 1. Issue the EPCTIN command to select the EEPROM Control mode (for data reading). 2. Issue the EPMRD command to read data from the EEPROM. 3. Issue the EPCTOUT command to cancel the EEPROM Control mode and updates the Electronic Control value and built-in resistance ratio using the read data. Miscellaneous: The MPU can read the Electronic Control value and built-in resistance ratio by issuing a combination of EPSRRD1 or EPSRRD2 and STREAD (Status Read) commands. 60 VDD GND SDA CLOCK RESET VDD GND SDA SCK XRST S1F65170M0A00 S1D15G00D00B100 EPSON Rev. 1.0 S1D15G00 Series 15. CAUTIONS Concerning this development specification, users are advised to pay attention to the following precautions. 1. This development specification is subject to modifications without previous notice. 2. This development specification does not grant the industrial property right or any other right, or exercising such rights. Application examples contained in this document are intended only to help users to understand the product better. SEIKO EPSON shall not be liable to any circuitrelated problem resulted from using these examples. Users are requested to pay attention to the following points when using S1D15G00 series. Precautions on Light Characteristics of semiconductor devices can be changed when exposed to light as described in the operational principles of solar batteries. Exposing this IC to light, therefore, can potentially lead to its malfunctioning. 1 Care must be exercised in designing the operation system and mounting the IC so that it may not be exposed light during operation 2 Care must be exercised in designing the inspection process and handling the IC so that it may not be exposed to light during the process. 3 The IC must be shielded from light in the front, back and side faces. Rev. 1.0 Precautions on External Noises 1 Internal state of S1D15G00 can be changed when exposed to adversely affecting external factors such as excessive noises though it can maintain the command-instructed operational status and display data. Thus, you must make sure when mounting the IC and designing the operation system that measures for eliminating noises or measures protecting the IC from noises are prepared. 2 In order to be prepared against sudden noise, it is recommended to prepare the software to perform periodic refreshing of operational state (re-setting of commands and re-transfer of display data). Precautions on Mounting COG When mounting COG, you must take into consideration of resistance component generated across the driver chip and externally connected parts (capacitor and resistor) resulting from ITO wiring. This resistance component can interfere with high-speed operation of liquid crystal display or MPU. When mounting COG, you must take into consideration of the following three points in the module design: 1. To minimize resistance between the driver chip pin to the external part. 2. To minimize resistance at the power terminal of the driver chip. 3. To develop sample COG modules with varying degrees of ITO sheet resistance in order to select one with the sheet resistance allowing sufficient operational margins. EPSON 61
