LIS3LV02DL 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
F Al) should be
placed as near as possible to the pin 13 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 7). It is possible to remove Vdd maintaining Vdd_IO
without blocking the communication busses. 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 while
SDO must be left floating. Refer to dedicated application note for further information on
device usage.
The functions, the trasholds and the timing of the interrupt pin (INT) can be completely
programmed by the user through the I2C/SPI interface.

Soldering Information
The LGA-16 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.
