External capacitors
The C1 and C2 external capacitors should have a low SR value ceramic type construction.
Reservoir capacitor C1 is nominally 4.7 µF in capacitance, with the set/reset capacitor C2
nominally 0.22 µF in capacitance.
The device core is supplied through the Vdd line. Power supply decoupling capacitors
(C4=100 nF ceramic, C3=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 obtain proper behavior of the IC (refer to
The functionality of the device and the measured acceleration/magnetic field data is
selectable and accessible through the I
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 I
Pull-up resistors
Pull-up resistors are placed on the two I
Digital interface power supply
This digital interface dedicated to the linear acceleration signal is capable of operating with a
standard power supply (Vdd) or using a dedicated power supply (Vdd_IO_A).
This digital interface dedicated to the magnetic field signal requires a dedicated power
supply (Vdd_dig_M).
The table below shows the modes available in the various power supply conditions.
