Embedded low-power features

The LSM6DS33 has been designed to be fully compliant with Android, featuring the

following on-chip functions:

 8 kbyte data buffering

–

100% efficiency with flexible configurations and partitioning

–

possibility to store time stamp

 Event-detection interrupts (fully configurable):

–

free-fall

–

wakeup

–

6D orientation

–

tap and double-tap sensing

–

activity / inactivity recognition

 Specific IP blocks with negligible power consumption and high-performance:

–

pedometer functions: step detector and step counters

–

tilt (Android compliant, refer to Section 2.1: Tilt detection for additional info

–

significant motion (Android compliant)

2.1

Tilt detection

The tilt function helps to detect activity change and has been implemented in hardware

using only the accelerometer to achieve both the targets of ultra-low power consumption

and robustness during the short duration of dynamic accelerations.

It is based on a trigger of an event each time the device's tilt changes by an angle greater

than 35 degrees from the start position.

The tilt function can be used with different scenarios, for example:

Trigger when phone is in a front pants pocket and the user goes from sitting to

standing or standing to sitting;

Doesn’t trigger when phone is in a front pants pocket and the user is walking,

running or going upstairs.
