100% efficiency with flexible configurations and partitioning

–

Possibility to store timestamp

•

Event-detection interrupts (fully configurable)

–

Free-fall

–

Wake-up

–

6D orientation

–

Activity/inactivity recognition

–

Stationary/motion detection

•

Specific IP blocks with negligible power consumption and high performance

–

Finite state machine

The ASM330LHB 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

vehicle status (stationary or moving), anti-theft alarm and shock 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. The figure below shows a generic state

machine.
