data sheet s15866ej1v0ds 11 pd168112 functional description serial control all information for driving the motor is processed by serial data from the cpu. the following parameters can be set by commands. - wait value for setting timing when a stepper motor is driven - motor current, motor revolution direction, and output excitation mode - pulse cycle, and number of pulses each command is assigned an address. each data can be updated by inputting 8-bit data. for the configuration of the data and details of commands, refer to serial interface specifications on page 12. 2-phase excitation mode by allowing a current of 100% to flow into output phases a and b, the motor can be driven with a large torque. the motor can be stopped in electrical cycle angle units of 90 . the two-phase excitation mode or 1-2 phase excitation mode is selected by a command. 1-2 phase excitation mode by allowing a current of 100% to flow into either output phase a or b and a current of 70% to flow into the other phase, the motor can be positioned with an accuracy higher than that in the two-phase excitation mode. the motor can be stopped in electrical cycle angle units of 45. the two-phase excitation mode or 1-2 phase excitation mode is selected by a command. reset function an initialization operation is performed and all the internal data is cleared to 0 when reset = low level. the output remains in the hi-z state. when reset = high level, commands can be input. be sure to perform a reset operation after power application. when reset = low level, the internal circuitry is stopped whenever possible, so that the self current consumption can be reduced. when input of the external clk is stopped, the current consumption can be lowered to 1 a max. power application sequence this ic has a logic power supply (v dd ) pin and an output power supply (v m ) pin. to turn on power, turn on v dd and then v m . to turn off power, turn off v m with v dd on, and then turn off v dd . (v dd and v m can also be turned on/off at the same time.)
data sheet s15866ej1v0ds 12 pd168112 serial interface specifications the internal data is determined by inputting 8-bit serial data synchronized with serial clock clk while latch = high level, and then lowering latch. serial data is input from the lsb (d0) to the msb (d7). sdata: data is loaded to the internal circuitry at the rising edge of sclk when latch = high level. latch: inputting sdata is prohibited when latch is low level. inputting sdata is enabled when it is high level. the internal data is determined at the negative transition of latch (high level low level). because this ic uses the external clk, osc in , to generate the internal timing, the set values vary depending on the frequency of osc in . an example where osc in = 5 mhz is given below. to input a frequency other than 5 mhz to osc in , use the following expression. this applies to the serial registers marked in serial register details on page 16 and 19. time: set value = setting example x (5/osc in [mhz] ) frequency: set value = setting example x (osc in [mhz] /5) data configuration data is configured of 8 bits. addresses are set in the order of command input. six types of addresses, 0 to 5, are used. bit d7d6d5d4d3d2d1d0 msb lsb for how to set data, refer to serial register list on page 14 and 15 and serial register details on page 16. the following chart shows an example of serial command waveforms. 01234567 sclk sdata latch data of one motor can be input in accordance with the motor driving data specifications that are set while latch = high level. the input data is loaded in 8-bit units when sclk = low level high level after latch = low level high level, and the data is determined when latch = high level low level. addresses 0 and 1 are used to perform initialization such as drive output settings. turning on/off the motor and the number of pulses are set by addresses 2 to 5. once initialization has been performed, therefore, the motor can be controlled simply by transmitting the drive data of addresses 2 to 5. the stepper motor operates in synchronization with the v d signal. to update data, be sure to input the v d signal (for details, refer to command input timing chart on page 8). when only the v d signal is input, the previous status is retained and the output does not change.
data sheet s15866ej1v0ds 13 pd168112 serial data input sequence the pd168112 can control driving of two or more motors with only a few cpu signals by using a serial data input method. the serial data is input as follows. (1) input addresses 0 and 1 after power application and initialization. (2) input addresses 3, 4, and 5, depending on the type of motor to be driven. (3) input address 2 to specify the motor to be driven. (4) only addresses 3 to 5 and 2 have to be input subsequently to specify driving. to perform an initialization operation such as selecting the motor, initialize the internal registers by using the reset pin. address 0 operation sequence when serial data is input motor type data updated? stepper motor constant-current driving address 2 y n address 1 dc motor address 4 address 5 address 3 ? 1 to 3 ? 4 -- initialization operation -- <1> input address 0. <2> input address 1. -- detailed drive settings -- <3> set addresses 3, 4, or 5.

data sheet s15866ej1v0ds 27 pd168112 notes for cmos devices 1 precaution against esd for semiconductors note: strong electric field, when exposed to a mos device, can cause destruction of the gate oxide and ultimately degrade the device operation. steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. environmental control must be adequate. when it is dry, humidifier should be used. it is recommended to avoid using insulators that easily build static electricity. semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. all test and measurement tools including work bench and floor should be grounded. the operator should be grounded using wrist strap. semiconductor devices must not be touched with bare hands. similar precautions need to be taken for pw boards with semiconductor devices on it. 2 handling of unused input pins for cmos note: no connection for cmos device inputs can be cause of malfunction. if no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. cmos devices behave differently than bipolar or nmos devices. input levels of cmos devices must be fixed high or low by using a pull-up or pull-down circuitry. each unused pin should be connected to v dd or gnd with a resistor, if it is considered to have a possibility of being an output pin. all handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 status before initialization of mos devices note: power-on does not necessarily define initial status of mos device. production process of mos does not define the initial operation status of the device. immediately after the power source is turned on, the devices with reset function have not yet been initialized. hence, power-on does not guarantee out-pin levels, i/o settings or contents of registers. device is not initialized until the reset signal is received. reset operation must be executed immediately after power-on for devices having reset function.

"standard": computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots. "special": transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support). "specific": aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipment for life support, etc. the quality grade of nec electronics products is "standard" unless otherwise expressly specified in nec electronics data sheets or data books, etc. if customers wish to use nec electronics products in applications not intended by nec electronics, they must contact an nec electronics sales representative in advance to determine nec electronics' willingness to support a given application.
