MA8652FC, 3-Axis, 12-bit, Digital
Accelerometer
The MMA8652FC is an intelligent, low-power, three-axis, capacitive micromachined
accelerometer with 12 bits of resolution. This accelerometer is packed with
embedded functions with flexible user-programmable options, configurable to two
interrupt pins. Embedded interrupt functions enable overall power savings, by
relieving the host processor from continuously polling data. There is access to
either low-pass or high-pass filtered data, which minimizes the data analysis
required for jolt detection and faster transitions. The device can be configured to
generate inertial wake-up interrupt signals from any combination of the
configurable embedded functions, enabling the MMA8652FC to monitor inertial
events while remaining in a low-power mode during periods of inactivity. The
MMA8652FC is available in a small 10-pin DFN package (2 mm x 2 mm x 1 mm).

digital output interface with programmable interrupts
• Four embedded channels of configurable motion detection (Freefall, Motion,
Pulse, Transient)
• Orientation (Portrait/Landscape) detection with programmable hysteresis
• Configurable automatic ODR change triggered by the Auto-Wake/Sleep
state change
• 32-sample FIFO
• High-Pass Filter Data available per sample and through the FIFO
•Self-Test
Typical applications
• Tilt compensation in e-compass applications
• Static orientation detection (Portrait/Landscape, Up/Down, Left/Right, Back/
F
ront position identification)
• Notebook, tablet, e-reader, and laptop tumble and freefall detection
• Real-time orientation detection (virtual reality and gaming 3D user orientation feedback)
• Real-time activity analysis (pedometer step counting, freefall drop detection for HDD, dead-reckoning GPS backup)
• Motion detection for portable product power saving (Auto-SLEEP and Auto-WAKE for cell phone, PDA, GPS, gaming)
• Shock and vibration monitoring (mechatronic compensation, shipping and warranty usage logging)
•
User interface (tilt menu scrolling, tap detection for button replacement
)
