... The SCA3000 includes an internal oscillator, reference and non-volatile memory that enable the sensor's autonomous operation within a system. The temperature sensor is used in some product applications to enhance the temperature stability. In that case, temperature information can also be read out from the device.

... Free-Fall Detection Free-Fall Detection (FFD) is intended to be used to save system resources. This feature activates the interrupt via the INT-pin when free-fall is detected. The minimum detectable distance depends on the individual product. Normal acceleration information is available when the FFD is enabled. VTI Technologies Oy www.vti.fi / SCA3000-E01 ...
