Figure 14. ASM330LHH electrical connections

The device core is supplied through the Vdd line while the I/O pads are supplied through the

Vdd_IO line. As a common design practice, the power supply decoupling capacitors

C1 = 100 nF ceramic and C2 =10 μF aluminum should be placed as near as possible to

pin 8, while C3 = 100 nF ceramic should be positioned as close as possible to pin 5.

All the voltage and ground supplies must be present at the same time to have proper IC

behavior.

The functionality of the device and the measured acceleration/angular rate data are

selectable and accessible through the I²C or SPI interfaces. When using the I²C protocol,

CS must be tied high. Every time the CS line is set to low level, the I²C bus is internally

reset.

All the functions, the threshold and the timing of the two interrupt pins can be completely

programmed by the user through the I²C/SPI interface.
