Figure 3.
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 3 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 Fig. 3). It is possible to remove Vdd mantaining Vdd_IO without blocking the
communication busses.
The functionality of the device and the measured acceleration data is selectable and accessible
through the I
floating. Refer to application note AN2041 for further information on device usage.
Soldering Information
The QFN-28 package is lead free and green package qualified for soldering heat resistance
according to JEDEC J-STD-020C. Central die pad and pin #1 indicator are physically
connected to GND. Land pattern and soldering recommendations are available upon request.
