MMA8453Q, 3-axis, 10-bit/8-bit
digital accelerometer
The MMA8453Q is a smart, low-power, three-axis, capacitive, micromachined
accelerometer with 10 bits of resolution. This accelerometer is packed with
embedded functions with flexible user programmable options, configurable to two
interrupt pins. Embedded interrupt functions allow for overall power savings
relieving the host processor from continuously polling data.
The MMA8453Q has user selectable full scales of ±2 g/±4 g/±8 g. The device can
be configured to generate inertial wakeup interrupt signals from any combination
of the configurable embedded functions allowing the MMA8453Q to monitor
events and remain in a low-power mode during periods of inactivity. The
MMA8453Q is available in a 16-pin QFN, 3 mm x 3 mm x 1 mm package.

digital output interface (operates to 2.25 MHz with 4.7 kΩ pullup)
• Two programmable interrupt pins for six interrupt sources
• Three embedded channels of motion detection
– Freefall or motion detection: one channel
– Pulse detection: one channel
– Jolt detection: one channel
• Orientation (portrait/landscape) detection with set hysteresis
• Automatic ODR change for auto-wake and return to sleep
•Self-test
• Current consumption: 6 μA to 165 μA
Typical applications
• E-compass applications
• Static orientation detection (portrait/landscape, up/down, left/right, back/front
position identification)
• Notebook, e-reader, and laptop tumble and freefall detection
• Real-time orientation detection (virtual reality and gaming 3D user position 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 (menu scrolling by orientation change, tap detection for button replacement
)
