Advanced features
4.5.1
Linear acceleration sensing
The LSM320HAY30 linear acceleration sensor includes a low-power mode characterized by
lower data rate refreshing. In this way the device, even when sleeping, continues sensing
acceleration and generating interrupt requests.
The “sleep-to-wakeup” function, in conjunction with low-power mode, allows further
reduction of system power consumption and the development of new smart applications.
When the sleep-to-wakeup function is activated,the LSM320HAY30 is able to automatically
wake up the linear acceleration sensor as soon as an interrupt event has been detected.
With this feature the system is efficiently switched from low-power mode to normal mode
based on user-selectable positioning and acceleration events, thus ensuring power-saving
and flexibility.
4.5.2
Angular rate sensing
Sleep mode, self-test and power-down
The LSM320HAY30 has advanced power-saving features for angular rate sensing thanks to
the availability of three different operating modes. When the device is set to sleep mode
configuration, the reading chain is completely turned off, resuting in low power consumption.
In this condition, the device turn-on time is significantly reduced, allowing simple external
power cycling.
Based on the table below, the user can select the desired operating mode using two
dedicated pins (ARST and ARPD).
High-pass filter reset (ARHP)
The LSM320HAY30 provides the possibility to reset the optional external high-pass filter by
applying a high logic value to the ARHP pad. This procedure ensures faster response,
especially during overload conditions. Moreover, this operation is recommended each time
the device is powered.
