2 Device functionality
2.1 Orientation detection
The device output can be configured to provide its orientation relative to gravity based on
orientation definitions, as illustrated in Figure 2 below.

2.2 Tap detection
The device can be configured to send an interrupt signal on a dedicated pin when “clicked”
in any direction (see Figure 4).
A more advanced feature also allows the detection of a “double click” event, with a
programmable time interval between the first and second click, to enable a “mouse button-
like” functionality.
These functions can be fully programmed. For additional information, please contact your
local STMicroelectronics sales office.

2.3 Post assembly device verification
A special function allows the user to check the sensor functionality without moving the
device (device verification). This functionality is enabled by connecting the FC30 to an MCU.
For the connection scheme and additional information, please contact your local
STMicroelectronics sales office.
2.4 Power down
The power down function allows the device to be put in an ultra-low power consumption
mode by applying a "logic 0" voltage value to the PD pad. In this state the measurement
chain is powered off.
