DESCRIPTION 2. FEATURES The S1D15E06 series is a single chip MLS driver for dot matrix liquid crystal displays which can be directly connected to the microcomputer bus. It accepts the 8bit parallel or serial display data from the microcomputer to store the data in the on-chip display data RAM, and issues liquid crystal drive signals independently of the microcomputer. The S1D15E06 series provides both 4 gray-scale display and binary display. It incorporates a display data RAM (132 × 160 × 2 bits). In the case of 4 gray-scale display, 2 bits of the on-chip RAM respond to one-dot pixels, while in the case of binary display, 1 bit of the on-chip RAM respond to one-dot pixels. The S1D15E06 series features 132 common output circuits and 160 segment output circuits. A single chip provides a display of 10 characters by 8 lines with 132 × 160 dots (16 × 16 dots) and display of 13 characters by 11 lines by the 12 × 12 dot-character font. Display data RAM read/write operations do not require operation clock from outside, thereby ensuring operation with the minimum current consumption. Furthermore, it incorporates a LCD-drive power supply characterized by low power consumption and a CR oscillator circuit for display clock; therefore, the display system of a handy and high-performance instrument can be realized by use of the minimum current consumption and minimum chip configuration. • Direct RAM data display by display data RAM • 4 gray-scale display (Normally white in normal display mode) RAM bit data (high order and low order) (1,1) : gray-scale 3, black (1,0) : gray-scale 2 (0,1) : gray-scale 1 (0,0) : gray-scale 0, white • Binary display (Normally white display is in normal mode) RAM bit data “1” : On and black “0” : Off and white • RAM capacity 132 × 160 × 2 = 42,240 bits • Liquid crystal drive circuit 132 common outputs and 160 segment outputs • High-speed 8-bit MPU interface (directly connectable to the MPUs of both 80/68 series) /serial interface possible • A variety of command functions Area scroll display, partial display, n-line reversal, display data RAM address control, contrast control, display ON/OFF, display normal/reverse rotation, display all lighting ON/OFF, liquid crystal drive power supply circuit control, display clock built-in oscillator circuit control • Lower power MLS drive technology Built-in high precision voltage regulation function • High precision CR oscillator circuit incorporated • Very low power consumption • Power supply Logic power supply: VDD – VSS = 1.7 to 3.6 V Liquid crystal drive power supply: V3 – VSS = 3.4 to 14.0 V (S1D15E06D01****), V3 – VSS = 3.4 to 16.0 V (S1D15E06D03****) • Wide operation temperature range: –40 to 85°C • CMOS process • Shipping form : Bare chips, TCP • Light and radiation proof measures are not taken in designing.

FUNCTIONAL DESCRIPTION 6.1 MPU Interface 6.1.1 Selection of Interface Type S1D15E06 series allows data to be sent via the 8-bit bi-directional data buses (D7 to D0) or serial data input (SI). By setting the polarity of the P/S pin to HIGH or LOW, you can select either 8-bit parallel data input or serial data input, as shown in Table 6.1. Table 6.1 P/S CS1 CS2 A0 HIGH : Parallel input LOW : Serial input CS1 CS1 CS2 CS2 A0 A0 RD WR C86 D7 D6 D5 to D0 RD WR C86 D7 D6 D5 to D0 — — — SI SCL (HZ) —: Fixed to HIGH or LOW HZ: High impedance state 6.1.2 parallel interface When the parallel interface is selected (P/S = HIGH), direction connection to the MPU bus of either 80 series MPU or 68 series MPU is performed by setting the 86 pin to either HIGH or LOW, as shown in Table 6.2. Table 6.2 P/S CS1 CS2 A0 RD WR D7 to D0 HIGH : 68 series MPU bus LOW : 80 series MPU bus CS1 CS1 CS2 CS2 A0 A0 E RD R/W WR D7 to D0 D7 to D0 The data bus signals are identified by a combination of A0, RD (E), and WR (R/W) signals as shown in Table 6.3.

Serial interface comprises a 8-bit shift register and 3-bit counter. The serial data are latched by the rising edge of serial clock signals in the order of D7, D6, .... and D0 starting from the serial data input pin. On the rising edge of 8th serial clock signal, they are converted into 8-bit parallel data to be processed. Whether serial data input is a display data or command is identified by A0 input. A0 = HIGH indicates display data, while A0 = LOW shows command data. The A0 input is read and identified at every 8 × n-th rising edge of the serial clock after the chip has turned active. Fig. 6.1 shows the serial interface signal chart.

Recommend to use an actual equipment to verify the operation. 6.1.4 Chip Selection The S1D15E06 series has two chip select pins; CS1 and CS2. MPU interface or serial interface is enabled only when CS1 = LOW and CS2 = HIGH. When the chip select pin is inactive, D0 to D5 are in the state of high impedance, while A0, RD and WR inputs are disabled. When serial interface is selected, the shift register and counter are reset. 6.1.5 Access to display data RAM and internal register Access to S1D15E06 series viewed from the MPU side is enabled only if the cycle time requirements are kept. This does not required waiting time; hence, high-speed data transfer is allowed. Furthermore, at the time of data transfer with the MPU, S1D15E06 series provides a kind of inter-LSI pipe line 12 processing via the bus holder accompanying the internal data bus. For example, when data is written to the display data RAM by the MPU, the data is once held by the bus holder. It is written to the display data RAM before the next data write cycle comes. On the other hand, when the MPU reads the content of the display data RAM, it is read in the first data read cycle (dummy), and the data is held in the bus holder. Then it is read onto on the system bus from the bus holder in the next data read cycle. Restrictions are imposed on the display data RAM read sequence. When the address has been set, specified address data is not output to the Read command immediately after that. The specified address data is output in the second data reading. This must be carefully noted. Therefore, one dummy read operation is mandatory subsequent to address setting or write cycle. Fig. 6.2 illustrates this relationship.

Access to the desired bit is enabled by specifying the page address and column address. When the 4 gray-scale is selected by the Display Mode command, display data input for gray-scale display are processed as a two-bit pair. Combination is as follows: (MSB, LSB) = (D1,D0), (D3,D2), (DS,D4), (D7,D6) When the RAM bit data is gray-scale 1 and 2, gray-scale display is realized according to the parameter of the Gray-scale Pattern Set command. Rev. 2.1 When binary display is selected by the Display Mode command, the RAM 1 bit built in the one-dot pixel responds to it. When the RAM bit data is “1”, the display is black. If it is “0”, the display is given in white. RAM bit data “1” : Light On Black (when display is in normal mode) “0” : Light Off White (when display is in normal mode) EPSON 13 S1D15E06 Series Display data D7 to D0 from the MPU correspond to LCD common direction, as shown in Fig. 6.3 and 6.4. Therefore, less restrictions when multi-chip usage. Furthermore, read/write operations from the MPU to the RAM are carried out via the input/output buffer. The read operation from Display data RAM is designed as an independent operation. Accordingly, even if the MPU accesses the RAM asynchronously during LCD display, no adverse effect is given to display.

Of the 4 gray-scale, 2 gray-scale of halftones (grayscale 2 and 1) has its level of contrast specified by the Gray-scale Set command. Gray-scale can be selected from 6 levels of contrast. 6.2.3 Page address circuit/column address circuit The address of the display data RAM to be accessed is specified by the Page Address Set command and Column Address Set command, as shown in Fig. 6.5 and Fig. 6.6. For Address incremental direction, either the column direction or page direction can be selected by the Address Direction command. Whichever direction is chosen, increment is carried out by positive one (+1) after write 14 or read operation. When the column direction is selected for address increment, the column address is increased by +1 for every write or read operation. After the column address has accessed up to 9FH, the page address is incremented by +1 and the column address shifts to 0H. When the page direction is selected for address increment, the page address is increased with the column address locked in position. When the page address has accessed up to 32H, the column address is incremented by +1, and the page address goes to 0H. Whichever direction is selected for address increment, the page address goes back to 0H and the column address to 0H after access up to the column address 9FH of page address 32H. As shown in Fig. 6.4, relationship between the display data RAM column address and segment output can be reversed by the Column Address Set Direction command. This will reduce restrictions on IC layout during LCD module assembling.

Normally, the top line of the display (COM0 output in the case of normal rotation of the common output status and COM131 output in the case of reverse rotation) is specified by the Display Start Line Address Set command. The display area starts from the specified display start line address to cover the area corresponding to the lines specified by the DUTY Set command in the direction where the line address increments. If the display start line address set command is used for dynamic modification of the line address, screen scroll and page change are enabled. 6.2.5 Area scroll The display area can be divided into the display area fixed in the COM direction and scrollable area by the area scroll command. The scroll area is set by a scroll mode, scroll start line address (AS), scroll end address (AE), and scroll display line count (AL) as parameters for the area scroll command. Display start line address (DL) in the scroll area can be specified by the display start line address set command.

Parameters AS, AE and AL are disabled, 6.2.5.2 Mode 1 (Upper scroll ) Reading starts from the line address DL to read AL lines as a scroll area. If the line address AE is read in the Rev. 2.1 middle of reading the scroll area, the line address to be read next will be 00H. When all the AL lines have been read, the address to be read next will be AE + 1. When reading is completed up to the final line address, the control goes back to the line address DL, and parameter AS is disabled. DL can be specified in the range from 00H to AE. EPSON 15 S1D15E06 Series 6.2.5.3 Mode 2 (lower scroll) Reading starts from line address 00H to reach the line address AS-1 in the continuous reading mode. Upon completion of reading of line address AS-1, the line address moves to the DL to read the area corresponding to AL lines from the line address DL as a scroll area. If the final line address is read in the middle of reading the scroll area, the line address to be read next will be AS. When all AL lines have been read, the control goes back to the line address 00H, and parameter AE is disabled. DL can be specified in the range from AS to the final line address. 6.2.5.4 Mode 3 (Center scroll) Reading starts from line address 00H to reach the line address AS-1 in the continuous reading mode. Upon completion of reading of line address AS-1, the line address moves to the DL to read the area corresponding to AL lines from the line address DL as a scroll area. If the final line address is read in the middle of reading the scroll area, the line address to be read next will be AS. When all AL lines have been read, the line address will be AE+1. When up to the final line address has been read, the control goes back to the line address 00H, DL can be specified in the range from AS to AE.

Display normal/ reverse, display ON/OFF, and display all lighting ON/ OFF commands control the data in this latch, without the data in the display data RAM being controlled. 6.2.7 Partial display Partial display of the screen is provided by the partial display ON/OFF command. The partial area (display start line, number of display lines) are set by the partial display set command. The display start line of the parameter shows the line assigned in the COM direction of the liquid crystal screen. It is different from the line address given in Fig. 6.5 and 6.6. Example: When the point is set at 1 (COM4 to 7) by the Duty Reset command, the display line is assigned as shown below. If the display start line 4 and display line count 3 are specified by the partial display set command, the display area is COM8 to COM10.

The oscillator circuit is enabled only when M/S = HIGH and CLS = HIGH. Oscillation starts after input of the builtin oscillator circuit ON command input. When CLS = LOW, oscillation stops, and display clock is input from the CL pin. 6.4 Display timing generation circuit Timing signals are generated from the display clock to the line address circuit and display data latch circuit. Synchronized with display clock, display data is latched in display data latch circuit, and is output to the segment drive output pin. Reading of the display data into the LCD drive circuit is completely independent of access from the MPU to the display data RAM. Accordingly, asynchronous access to the display data RAM during LCD display does not give any adverse effect; like as flicker. Furthermore, the display clock generates internal common timing, liquid crystal alternating signal(FR), field start signal (CA) and drive pattern signal (Fl and F2). The FR normally generates 2-frame alternating drive system drive waveform to the liquid crystal drive circuit. The n-line reverse alternating drive waveform is generated for each 4 × (a+1) line by setting data on the n-line reverse drive register. When there is a display quality problem including crosstalk,the problem may be solved using the n-line reverse alternating drive. Execute liquid crystal display to determine the number of lines “n” for alternation. When you want to use the S1D15E06 series in multichip configuration, supply display timing signal (FR, CA, F1, F2, CL, DOF) to the slave side from the master side. Table 6.5 shows the statuses of FR, CA, F1, F2, CL, DOF.

It selects three values of V3, VC and MV3(VSS) using the driver control signal determined by the decoder, and output them. S1D15E06 series allows the COM output scanning direction to be set by the common output status select command. (See Table 6.6). This will reduce restrictions on IC layout during LCD module assembling.

It consists of a step-up circuit, voltage regulating circuit and liquid crystal drive voltage generating circuit, and is enabled only during master operation. The power supply circuit uses the power control set command to provide an on/off control of step-up circuit, voltage regulating circuit and liquid crystal drive potential generating circuit. This allows a combined use of the external power supply and part of built-in power supply functions. Table 6.7 shows functions controlled by the 5-bit data of the control set command, and Table 6.8 shows reference combinations. The power supply circuit is enabled only during master operation.

Rev. 2.1 EPSON 21 S1D15E06 Series only by the command without adding any external parts. The variable range of the VC voltage is from about 1.6 to 7.0 [V]. When the internal step-up is used, or VOUT is input for use, the V OUT potential should be, in principle, the voltage 20% or more higher than the maximum voltage of the V C to be used, giving consideration to temperature characteristics. 6.6.2 Voltage Regulating Circuit VOUT generated from the step-up circuit or VOUT input from the outside produces liquid crystal drive voltage V C via the voltage regulating circuit. The voltage regulating circuit is controlled by liquid crystal drive voltage change command and electronic volume. The S1D15E06 series has a high precision constant voltage source, and incorporates 4-step liquid crystal drive voltage change command and 128-step electronic volume functions. This makes it possible to provide a high precision liquid crystal drive voltage regulation Example: When VC output is 7 [V], VOUT ≥ 8.4 [V] (three times 2.8 [V], etc.) When VC output is 4 [V], VOUT ≥ 4.8 [V] (two times 2.4 [V], three times 1.8 [V]) • Electronic volume α of Table 6.9 indicates an electronic volume command value. It takes one of 128 states when the data is set in the 7-bit electronic volume register. Table 6.9 shows the value of α by setting the data in the electronic volume register.

Actually verify the display of a pattern with big load to make a decision. *5 Precautions when installing the COG When installing the COG, it is necessary to duly consider the fact that there exists a resistance of the ITO wiring occurring between the driver chip and the externally connected parts (such as capacitors and resistors). By the influence of this resistance, non-conformity may occur with the indications on the liquid crystal display. When installing the COG, we recommend to use the "4 External power supply only" 6.6.4 Temperature gradient select circuit This is a circuit to select the temperature gradient characteristics of the liquid crystal drive power supply voltage. Temperature gradient characteristics can be selected from eight states by the Temperature Gradient command. Selection of temperature gradient characteristics conforming to the temperature characteristics of the liquid crystal to be used makes it possible to configure a system without providing an external element for temperature characteristics compensation. 6.7 Reset circuit When the RES input becomes LOW, this LSI is set to the initialized state.

Register data in the serial interface : Clear When the Reset command is used, only the abovementioned inilialized items 7, 8 and 19 are executed. When power is turned on, initialization by the RES pin is necessary. After initialization by the RES pin, each input pin must be controlled correctly. Furthermore, when control signals from the MPU have a high impedance, the excessive current may flow to the IC. After VDD is applied, measures should be taken to ensure that the input pin does not have a high impedance. The S1D15E06 series discharges the electric charge of VOUT and liquid crystal drive voltage (V3, V2, V1, VC, MV1, MV2) at the level of RES pin = LOW. When liquid crystal drive external power supply is used, external power supply should not be supplied during the period of RES = LOW to prevent external power supply and VDD from being short circuited. EPSON Rev. 2.1 S1D15E06 Series 7. COMMAND The S1D15E06 series identifies data bus signals by a combination of A0, RD(E) and WR(R/W). Interpretation and execution of the command are executed by the internal timing alone which is independent of the external clock. This allows high-speed processing. The 80 series MPU interface allows the command to be started by entering the low pulse in the RD pin during reading and by entering the low pulse in the WR pin during writing. The 68 series MPU interface allows a read state to occur by entering HIGH in the R/W pin, and permits a write state to occur by entering LOW. It also allows the command to be started by entering the high pulse in the pin E. (For timing, see the description of “10. Timing characteristics”). Accordingly, the 68 series MPU interface is different from 80 series MPU interface in that RD(E) is “1(H)” in the case of display data/read shown in the Command Description and Command Table. The following describes the commands, based on the example of the 80 series MPU interface: When the serial interface is selected, enter data sequentially starting from D7. Command Description (1) Display ON/OFF This command sets the display ON/OFF.

In the initial setting state, it becomes "D0 = 0". * When D0 = 0 is selected in the case of S1D15E06D00B*, the MV2 and common driver VSS level is output by segment driver when display is off. Select D0 = 1 to use the S1D15E06D00B*.

Access to the display data RAM from the MPU is also possible. The current consumption is reduced to the value close to static current if all operations of the LCD display system are stopped and there is no access from the MPU. In the power save mode, the following occurs: Stop of oscillator circuit Stop of LCD power supply circuit Stop of all liquid crystal drive circuit (VSS level output is issued as the segment and common driver output). The power save OFF command releases the power save mode. The system goes back to the state before the power save mode. * When the external power supply is used, it is recommended to stop the external power supply circuit function when the power save mode is started. For example, when each level of the liquid crystal drive voltage is given from the external resistive divider circuit, it is recommended to add a circuit to cut off the current flowing to the resistive divider circuit when power save function is started. The S1D15E06 series has a liquid crystal display blanking control control pin DOF, and the level goes LOW when power save function is started. You can use the DOF output to stop the external power supply circuit function. 42 EPSON Rev. 2.1 S1D15E06 Series (31) Temperature Gradient Set The 3-bit data of this command is used to set the temperature gradient characteristics of the liquid crystal drive voltage output from the built-in power supply circuit from eight states to one state.

In case the B/W indication is selected after resetting, dispersive drive will be preset. Dispersive drive and nondispersive drive are the LCD drive methods characteristic to the MLS drive. The S1D15E06 Series is making 4 line MLS drive and, 4 times higher period selection voltage than that of the period being used for indication of 1 line in an ordinary drive (in case of 132 line indication, the period of 1/132 of 1 frame). In case of the dispersive drive, the selection signals will be output for four times, separately, within the period of 1 frame. With this dispersive drive method, it is possible to reduce the frame frequency as compared with the nondispersive drive method. Therefore, when it becomes necessary to reduce the current consumption, we recommend you to use this dive method. However, in case of the drive method where moving pictures are to be indicated, the indication may become flickered and this dispersive drive method is not suitable for indications of moving pictures.
