SCA3000 Series

1.2.3 Factory calibration

Sensors are factory calibrated and the trimmed parameters are gain, offset and the frequency of

the internal oscillator. Calibration parameters will be read automatically from the internal non-

volatile memory during sensor startup.

1.2.4 Supported features

Features supported by individual SCA3000 products are listed in Table 1 below.

1.2.5 Operation modes

1.2.5.1 Measurement

The SCA3000 is in normal measurement mode by default after start up. The sensor offers

acceleration information via the SPI or I²C when the master requires it. The master can acquire one

axis acceleration or all three axis acceleration depending on the application. Measurement

resolution depends on the product type (see Table 1).

1.2.5.2 Motion Detection

Motion Detection (MD) mode is intended to be used to save system level power consumption. In

this mode, the SCA3000 activates the interrupt via the INT-pin when motion is detected. Sensitivity

levels can be configured via the SPI or I²C bus for each axis. Moreover, the detection condition can

be defined using sensitivity directions with AND / OR / mux logic. Once the interrupt has happened,

the detected direction can be read out from the corresponding status register.

Normal acceleration information is not available in MD mode.

1.2.6 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.
