GND
Digital signal from/to signal controller. Signal levels are defined through proper selection of Vdd_
The device core is supplied through the Vdd line. Power supply decoupling capacitors (100
nF ceramic, 10 µF aluminum) should be placed as near as possible to the supply pad of the
device (common design practice).
The functionality of the device and the measured data outputs are selectable and accessible
through the I²C/SPI interface. When using the I²C, CS must be tied high (i.e. connected to
Vdd_IO).
Soldering information
The HCLGA package is compliant with the ECOPACK^® standard and it is qualified for
soldering heat resistance according to JEDEC J-STD-020.
