docid028370 rev 4 15/104 lsm6ds3h overview 104 1 overview the lsm6ds3h is a system-in-package featuring a high-performance 3-axis digital accelerometer and 3-axis digital gyroscope. the integrated power-efficient modes are able to reduce the power consumption down to 1.1 ma in high-performance mode, combining always-on low-power features with superior sensing precision for an optimal motion experience for the consumer thanks to ultra-low noise performance for both the gyroscope and accelerometer. the lsm6ds3h delivers best-in-class motion sensing that can detect orientation and gestures in order to empower application developers and consumers with features and capabilities that are more sophisticated than simply orienting their devices to portrait and landscape mode. the event-detection interrupts enable efficient and reliable motion tracking and contextual awareness, implementing hardware recognition of free-fall events, 6d orientation, tap and double-tap sensing, activity or inactivity, and wakeup events. the lsm6ds3h supports main os requirements, offering real, virtual and batch mode sensors. in addition, the lsm6ds3h can efficiently run the sensor-related features specified in android, saving power and enabling faster reaction time. in particular, the lsm6ds3h has been designed to implement hardware features such as significant motion, tilt, pedometer functions, timestamping and to support the data acquisition of an external magnetometer with ironing correction (hard, soft). the lsm6ds3h offers hardware flexibility to connect the pins with different mode connections to external sensors to expand functionalities such as adding a sensor hub, auxiliary spi, etc. the application processor connection is supported by both spi and i 2 c interfaces for complete interface flexibility. up to 8 kbyte of fifo [4 kbyte fifo + flexible 4 kbyte (fifo or programmable)] with dynamic allocation of significant data (i.e. external sensors, timestamp, etc.) allows overall power saving of the system. like the entire portfolio of mems sensor modules, the lsm6ds3h leverages the robust and mature in-house manufacturing processes already used for the production of micromachined accelerometers and gyroscopes. the various sensing elements are manufactured using specialized micromachining processes, while the ic interfaces are developed using cmos technology that allows the design of a dedicated circuit which is trimmed to better match the characteristics of the sensing element. the lsm6ds3h is available in a small plastic land grid array (lga) package of 2.5 x 3.0 x 0.83 mm to address ultra-compact solutions.
embedded low-power features lsm6ds3h 16/104 docid028370 rev 4 2 embedded low-power features the lsm6ds3h has been designed to be fully compliant with android, featuring the following on-chip functions: ? 8 kbyte data buffering ? 4 kbyte fifo + flexible 4 kbyte (fifo or programmable) ? 100% efficiency with flexible configurations and partitioning ? possibility to store timestamp ? event-detection interrupts (fully configurable): ? free-fall ? wakeup ? 6d orientation ? tap and double-tap sensing ? activity / inactivity recognition ? specific ip blocks with negligible power consumption and high-performance: ? pedometer functions: step detector and step counters ? tilt (android compliant, refer to section 2.1: tilt detection for additional info ? significant motion (android compliant) ? sensor hub ? up to 6 total sensors: 2 internal (accelerometer and gyroscope) and 4 external sensors ? data rate synchronization with external trigger for reduced sensor access and enhanced fusion 2.1 tilt detection the tilt function helps to detect activity change and has been implemented in hardware using only the accelerometer to achieve both the targets of ultra-low power consumption and robustness during the short duration of dynamic accelerations. it is based on a trigger of an event each time the device's tilt changes by an angle greater than 35 degrees from the start position. the tilt function can be used with different scenarios, for example: a) trigger when phone is in a front pants pocket and the user goes from sitting to standing or standing to sitting; b) doesn?t trigger when phone is in a front pants pocket and the user is walking, running or going upstairs.

module specifications lsm6ds3h 28/104 docid028370 rev 4 4.6 terminology 4.6.1 sensitivity linear acceleration sensitivity can be determined, for example, by applying 1 g acceleration to the device. because the sensor can measure dc accelerations, this can be done easily by pointing the selected axis towards the ground, noting the output value, rotating the sensor 180 degrees (pointing towards the sky) and noting the output value again. by doing so, 1 g acceleration is applied to the sensor. subtracting the larger output value from the smaller one, and dividing the result by 2, leads to the actual sensitivity of the sensor. this value changes very little over temperature and over time. the sensitivity tolerance describes the range of sensitivities of a large number of sensors. an angular rate gyroscope is device that produces a positive-going digital output for counterclockwise rotation around the axis considered. sensitivity describes the gain of the sensor and can be determined by applying a defined angular velocity to it. this value changes very little over temperature and time. 4.6.2 zero- g and zero-rate level linear acceleration zero- g level offset (tyoff) describes the deviation of an actual output signal from the ideal output signal if no acceleration is present. a sensor in a steady state on a horizontal surface will measure 0 g on both the x-axis and y-axis, whereas the z-axis will measure 1 g . ideally, the output is in the middle of the dynamic range of the sensor (content of out registers 00h, data expressed as 2?s complement number). a deviation from the ideal value in this case is called zero- g offset. offset is to some extent a result of stress to mems sensor and therefore the offset can slightly change after mounting the sensor onto a printed circuit board or exposing it to extensive mechanical stress. offset changes little over temperature, see ?linear acceleration zero- g level change vs. temperature? in table 3 . the zero- g level tolerance (tyoff) describes the standard deviation of the range of zero- g levels of a group of sensors. zero-rate level describes the actual output signal if there is no angular rate present. the zero-rate level of precise mems sensors is, to some extent, a result of stress to the sensor and therefore the zero-rate level can slightly change after mounting the sensor onto a printed circuit board or after exposing it to extensive mechanical stress. this value changes very little over temperature and time.

digital interfaces lsm6ds3h 36/104 docid028370 rev 4 6.1.1 i 2 c operation the transaction on the bus is started through a start (st) signal. a start condition is defined as a high to low transition on the data line while the scl line is held high. after this has been transmitted by the master, the bus is considered busy. the next byte of data transmitted after the start condition contains the address of the slave in the first 7 bits and the eighth bit tells whether the master is receiving data from the slave or transmitting data to the slave. when an address is sent, each device in the system compares the first seven bits after a start condition with its address. if they match, the device considers itself addressed by the master. the slave address (sad) associated to the lsm6ds3h is 110101xb. the sdo/sa0 pin can be used to modify the less significant bit of the device address. if the sdo/sa0 pin is connected to the supply voltage, lsb is ?1? (address 1101011b); else if the sdo/sa0 pin is connected to ground, the lsb value is ?0? (address 1101010b). this solution permits to connect and address two different inertial modules to the same i 2 c bus. data transfer with acknowledge is mandatory. the transmitter must release the sda line during the acknowledge pulse. the receiver must then pull the data line low so that it remains stable low during the high period of the acknowledge clock pulse. a receiver which has been addressed is obliged to generate an acknowledge after each byte of data received. the i 2 c embedded inside the lsm6ds3h behaves like a slave device and the following protocol must be adhered to. after the start condition (st) a slave address is sent, once a slave acknowledge (sak) has been returned, an 8-bit sub-address (sub) is transmitted. the increment of the address is configured by the ctrl3_c (12h) (if_inc). the slave address is completed with a read/write bit. if the bit is ?1? (read), a repeated start (sr) condition must be issued after the two sub-address bytes; if the bit is ?0? (write) the master will transmit to the slave with direction unchanged. table 11 explains how the sad+read/write bit pattern is composed, listing all the possible configurations. table 11. sad+read/write patterns command sad[6:1] sad[0] = sa0 r/w sad+r/w read 110101 0 1 11010101 (d5h) write 110101 0 0 11010100 (d4h) read 110101 1 1 11010111 (d7h) write 110101 1 0 11010110 (d6h) table 12. transfer when master is writing one byte to slave master st sad + w sub data sp slave sak sak sak table 13. transfer when master is writing multiple bytes to slave master st sad + w sub data data sp slave sak sak sak sak
