Embedded low-power features

The LSM6DSOP features the following on-chip functions:

 9 kbytes data buffering, data can be compressed two or three times

–

100% efficiency with flexible configurations and partitioning

–

Possibility to store timestamp

 Event-detection interrupts (fully configurable):

–

Wakeup

–

6D orientation

–

Activity/inactivity recognition

–

Stationary/Motion detection

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

–

Finite State Machine (FSM) for accelerometer, gyroscope

Finite State Machine

The LSM6DSOP can be configured to generate interrupt signals activated by user-defined

motion patterns. To do this, up to 16 embedded finite state machines can be programmed

independently for motion detection such as glance gestures, absolute wrist tilt, shake and

double-shake detection.

Definition of Finite State Machine

A state machine is a mathematical abstraction used to design logic connections. It is a

behavioral model composed of a finite number of states and transitions between states,

similar to a flow chart in which one can inspect the way logic runs when certain conditions

are met. The state machine begins with a start state, goes to different states through

transitions dependent on the inputs, and can finally end in a specific state (called stop state).

The current state is determined by the past states of the system. Figure 1: Generic state

machine shows a generic state machine.
