31 / 66 page LSM330D Application hints Doc ID 022562 Rev 2 31/66 5 Application hints Figure 13. LSM330D electrical connection 5.1 External capacitors The device core is supplied through Vdd line. Power supply decoupling capacitors (C1=C3 = 100 nF ceramic, C2=10 µF Al) should be placed as near as possible to the supply pin 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 13). The functionality of the device and the measured acceleration/angular rate data are selectable and accessible through the SPI/I2C interface. The functions, the threshold and the timing of the two interrupt pins for each sensor can be completely programmed by the user though the SPI/I2C interface. 5.2 Soldering information The LGA package is compliant with ECOPACK®, RoHS and “Green” standards. It is qualified for soldering heat resistance according to JEDEC J-STD-020D. Leave “Pin 1 Indicator” unconnected during soldering. Land pattern and soldering recommendations are available at www.st.com/mems.
