description the S1D15710 series is a single-chip dot matrix liquid crystal display driver that can be connected directly to a microprocessor bus. eight-bit parallel or serial display data transmitted from the microprocessor is stored in the internal display data ram, and the chip generates liquid crystal drive signals, independently of the microprocessor. it has a on-chip 65 256-bit display data ram, and there is a one-to-one correspondence between the dot pixel on the liquid crystal panel pixels and internal ram bit. this feature ensures implementation of highly free display. the S1D15710 series incorporate 65 common output circuits and 224 segment output circuits. a single chip can drive a 65 224 dot display (capable of displaying 14 columns 4 rows with 16 16-dot kanji font). further, display capacity can be extended by designing two chips in a master/display configuration. since both the S1D15710 * 10 ** and S1D15710 * 11 ** have built-in analog temperature sensor circuits, systems can be build that can maintain appropriate liquid crystal contrast over a wide temperature range with microcomputer control without requiring such parts as thermostats. the S1D15710 series can read and write ram data with the minimum current consumption because it does not require any external operation clock. also it incorporates a lcd power supply featuring a very low current consumption, a lcd drive power voltage regulator resistor and a display clock cr oscillator circuit. this allows the display system of a high- performance for handy equipment to be realized at the minimum power consumption and minimum component configuration. 2. features direct display of ram data using the display data ram ram bit data ??.... goes on. ??.... goes off (at display normal rotation). ram

S1D15710 series has two chip select pins cs1 and cs2 and enables the mpu interface or serial interface only when cs1=low and cs2=high. when chip select is in the non-active state, d0 to d7 are in the high impedance state and the a0, rd, and wr inputs become invalid. when the serial interface is selected, the shift register and counter are reset. display data ram and internal register access since the S1D15710 series access viewed from the mup side satisfies the cycle time and does not require the wait time, high-speed data transfer is enabled. the S1D15710 series performs a kind of inter-lsi pipeline processing through the bus holder attached to the internal data bus when it performs the data transfer with the mpu. for example, when data is written on the display data ram, the data is first held in the bus holder and written serial interface when the serial interface is selected (p/s=low), the serial data entry (si) and serial clock input(scl) can be accepted with the chip in the non-active state (cs1=low or cs2=high. the serial interface consists of an 8-bit shift register and a 3-bit counter. serial data is fetched from the serial data entry pin in the order of d7, d6, ...., and d0 on the leading edge of the serial clock and converted into 8-bit parallel data on the leading edge of the 8th serial clock, then processed. whether to identify that the serial data entry is display data or command is judged by the a0 input, and a0=high indicates display data and a0=low indicates the command. after the chip is set to the non-active state, the a0 input is read and identified at the timing on the 8 n-th leading edge of the serial clock. figure 1 shows the signal chart of the serial interface. on the display data ram up to the next data write cycle. further, when the mpu reads the contents of display data ram, the read data at the first data read cycle (dummy) is held in the bus holder and read on the system bus from the bus holder up to the next data read cycle. the read sequence of the display data ram is restricted. when the address is set, note that the specified address data is not output to the subsequent read instruction and output at the second data read. therefore single dummy read is required after the address set and write cycle. figure 2 shows this relationship. busy flag when the busy flag is ?? it indicates that the S1D15710 series is performing an internal operation, and only the status read instruction can be accepted. the busy flag is output to the d7 pin using the status read command. if the cycle time ( t cyc ) is ensured, the mpu throughput can be improved greatly since this flag needs not be checked before each command. figure 1 when the chip is in the non-active state, both the shift register and counter are reset to the initial state. cannot be read for the serial interface. for the scl signal, pay careful attention to the terminating reflection of lines and external noise. the operation confirmation using actual equipment is recommended. cs1 cs2 si scl a0 d7 1234567891011121314 d6 d5 d4 d3 d2 d7 d6 d5 d4 d3 d2 d1 d0 6. function description S1D15710 series (rev. 1.1c) epson 13 ?write n n n+1 n+2 n+3 n+1 n+2

dot data and consists of 65 (8 pages one 8 bit + 1) 256 bits. desired bits can be accessed by specifying page and column addresses. since the mpu display data d7 to d0 correspond to the common direction of the liquid crystal display, the restrictions at display data transfer is reduced and the display configuration with the high degree of freedom can easily be obtained when the S1D15710 series is used for the multiple chip configuration. besides, the read/write operation to the display data ram is performed through the i/o buffer from the mpu side independently of the liquid crystal drive signal read. therefore even when the display data ram is asynchronously accessed during liquid crystal display, the access will not have any adverse effect on the display such as flickering. page address circuit as shown in figure 4, the page address of the display data ram is specified using the page address set command. to access the data using a new page, the page address is respecified. the page address 8 (d3,d2,d1,d0=1,0,0,0) is an indicator dedicated ram area and only the display data d0 is valid. column address circuit as shown in figure 4, the display data ram column address is specified by the column address set command. the specified column address is incremented by +1 at every input of display data read/write command. this allows the mpu to access the display data continuously. incrementation of the column address is stopped by ffh. when display data is accessed continuously, the column address continues to specify the ffh after access of the ffh. it should be noted that the column address ffh display data is accessed repeatedly. the column address and page address are independent of each other. therefore, when shifting from the column of page 0 to the column of page 1, for example, it is necessary to specify each of the page address and column address again. furthermore, as shown in table 4, the ad command (segment driver direction select command) can used to reverse the correspondence between the display data ram column address and segment output. this allows constraints on ic layout to be minimized at the time of lcd module assembling. table 4 line address circuit when displaying contents of the display data ram, the line address circuit is used for specifying the corresponding addresses. see figure 4. using the display start line address set command, the top line is normally selected (when the common output state is normal, com0 is output. and, when reversed outputs com63). for the display area of 65 lines is secured starting from the specified display start line address in the address incrementing direction. dynamically changing the line address using the display start line address set command enables screen scrolling and page change. figure 3 d0 d1 d2 d3 d4 0 1 0 0 1 1 0 0 1 0 1 0 0 1 0 1 0 0 1 0 0 0 0 0 0 display data ram com0 com1 com2 com3 com4 liquid crystal display seg output seg0 seg223 adc

common output state: normal rotation when setting the display start line to one channel start the 65th line is accessed independently of the display start line address. 6. function description 16 epson S1D15710 series (rev. 1.1c) display data latch circuit the display data latch circuit is a latch that temporarily stores the display data output from the display data ram to the liquid crystal drive circuit. since the display normal rotation/reversal, display on/off, and display all lighting on/off commands control the data in this latch, the data within the display data ram is not changed. oscillator circuit this oscillator circuit is a cr type oscillator and generates display clocks. the oscillator circuit is valid only when m/s=high and cls=high and starts oscillation after the built-in oscillator circuit on command is entered. when cls=low, the oscillation is stopped and the display clocks are entered from the cl pin. display timing generator circuit this display timing generator circuit generates timing signals from the display clocks to the line address circuit and the display latch circuit. it latches the display data to the display data latch circuit and outputs it to the segment drive output pin by synchronizing to the display clocks. the read operation of display data to the liquid crystal drive circuit is completely independent of the access to the display data ram from the mpu. therefore even when the display data ram is asynchronously accessed during liquid crystal display, the access will not have any adverse effect on the display such as flickering. the circuit also generates the internal common timing, liquid crystal alternating current signal (fr), and synchronous signal (sync) from the display clocks. as shown in figure 5, the fr normally generates the drive waveforms in the 2-frame alternating current drive system to the liquid crystal drive circuit. it can generate n-line reversal alternating current drive waveforms by setting data (n-1) to the n-line reversal drive register. if a display quality problem such as crosstalk occurs, it can be improved by using the n-line reversal alternating current drive waveforms. determine the number of lines (n) to which alternating current is applied by actually displaying the liquid crystal. snyc is a signal that synchronizes the line counter and common timing generator circuit to the sync signal output side ic. therefore the sync signal becomes a waveform at a duty ratio of 50% that synchronizes to the frame synchronization. when the S1D15710 series is used for the multiple chip configuration, the slave side needs to supply the display timing signals (fr, sync, cl, and dof) from the master side. table 5 shows the state of fr, sync, cl, or dof. 2-frame alternating current

although the combinations other than those listed in the above table are also possible, they cannot be recommended because they are not actual use methods. power supply circuit this power supply circuit is a low power supply consumption one that generates the voltage required for the liquid crystal drive and consists of a boosting circuit, voltage adjusting circuit, and voltage follower circuit. it is valid only at master operation. the power supply circuit on/off controls the boosting circuit, voltage adjusting circuit, and voltage follower circuit using the power supply control set command, respectively. therefore, it can also use the partial functions of the external power supply and built-in power supply together. table 7 lists the functions that control 3-bit data using the power control set command and table 8 lists the reference combinations. boosting circuit the boosting circuit incorporated in the S1D15710 series enables the quadruple boosting, triple boosting, and double boosting of the v dd ?v ss2 potential. for the quadruple boosting, the v dd ? v ss2 potential is quadruple-boosted to the negative side and output to the v out pin by connecting the capacitor c1 between cap1+ ? and cap1? between cap2+ ? and cap2? between cap1+ ? and cap3? and between v ss2 ? and v out . for the triple boosting, the v dd ? v ss2 potential is triple-boosted to the negative side and output to the v out pin by connecting the capacitor c1 between cap1+ ? and cap1? between cap2+ ? and cap2? and between v ss2 ? and v out and strapping both cap3?and v out pins. for the double boosting, the v dd ? v ss2 potential is doubly boosted to the negative side and output to the v out pin by connecting the capacitor c1 between cap1+ ? and cap1? and between v ss2 ? , setting cap2+ to open, and v out and strapping cap2? cap3? and v out pins. figure 8 shows the relationships of boosting potential. 6. function description 20 epson S1D15710 series (rev. 1.1c) voltage adjusting circuit the boosting voltage generated in v out outputs the liquid crystal drive voltage v 5 through the voltage adjusting circuit. since the S1D15710 series incorporates a high-accuracy constant power
