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.
®
, RoHS and “Green” compliant
FC30
MEMS functional sensor:
LGA-14
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
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.
