17 / 42 page  LIS331DL Application hints 17/42 4 Application hints Figure 5. LIS331DL electrical connection The device core is supplied through Vdd line while the I/O pads are supplied through Vdd_IO line. Power supply decoupling capacitors (100 nF ceramic, 10 µF Al) should be placed as near as possible to the pin 14 of the device (common design practice). All the voltage and ground supplies must be present at the same time to have proper behavior of the IC (refer to Figure 5). It is possible to remove Vdd maintaining Vdd_IO without blocking the communication bus, in this condition the measurement chain is powered off. The functionality of the device and the measured acceleration data is selectable and accessible through the I2C/SPI interface.When using the I2C, CS must be tied high. The functions, the threshold and the timing of the two interrupt pins (INT 1 and INT 2) can be completely programmed by the user through the I2C/SPI interface. 4.1 Soldering information The LGA package is compliant with the ECOPACK®, RoHS and “Green” standard. It is qualified for soldering heat resistance according to JEDEC J-STD-020C. Leave “Pin 1 Indicator” unconnected during soldering. Land pattern and soldering recommendation are available at www.st.com/mems. 10µF Vdd 100nF GND Vdd_IO INT 1 INT 2 Digital signal from/to signal controller.Signal’s levels are defined by proper selection of Vdd_IO 1 59 13 TOP VIEW |
