Product Details

Xtrinsic 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.

Features

• 1.95V to 3.6V supply voltage
• 1.6V to 3.6V interface voltage
• ±2g/±4g/±8g dynamically selectable full-scale
• Output Data Rates (ODR) from 1.56 Hz to 800 Hz
• 99 μg/√Hz noise
• 10-bit and 8-bit digital output
•I2Cdigital output interface (operates to 2.25 MHz with 4.7 kΩpullup)
• Two programmable interrupt pins for six interrupt sources
• Three embedded channels of motion detection
– Freefall or Motion Detection: 1 channel
– Pulse Detection: 1 channel
– Jolt Detection: 1 channel
• Orientation (Portrait/Landscape)detection with set hysteresis
• Automatic ODR change for Auto-WAKE and return to SLEEP
•Self-Test
• RoHS compliant
• 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 cellphone, 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)
