Description
The FC30 is a stand-alone 3D orientation and click/double-click detection device. When in a steady position, it is able to detect 6 different orientations with respect to the gravity field, with notification provided through dedicated signal lines. The device can be used for image rotation (portrait/landscape) and position-based applications. When a single or double mechanical tap is detected, the FC30 provides an interrupt signal, enabling a “mouse button-like” function for intuitive man-machine interface solutions. A power-down mode selectable through a dedicated input pin ensures very low current consumption in battery-operated devices. The FC30 is available in an LGA-14 3x5x0.9mm SMD plastic full-moulded package compliant with lead-free, RoHS and halogen-free regulations. Compatible with a -40 ° C to +85 ° C temperature range, the FC30 is shipped in standard tape and reels for automatic pick and place machines and is washable after reflow due to its completely sealed and hermetic structure.

2.1 Orientation detection
orientation definitions, as illustrated in Figure 2 below. Figure 2. Orientation definitions Figure 3 shows the three interrupt output lines for the selected orientation.

2.2 Tap detection
in any direction (see Figure 4). local STMicroelectronics sales office. Figure 4. Tap or “click” detection
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 1" voltage value to the PD pad. In this state the measurement chain is powered off.

4 Device and technology information
The FC30 is an ultra-compact, low power 3-dimensional orientation and click/double-click sensor. Manufactured with MEMS technology, the FC30 offers many advantages compared to the conventional fabrication technology used nowadays in portable devices, including:
- Potential for additional strong miniaturization, leveraging the characteristics of micromachining technology
- No surface friction effects, wear effects and acoustic noise generation
- Embedded electronic signal conditioning allows reduced power consumption
