1 / 47 page  Freescale Semiconductor Document Number: MMA8453Q Data Sheet: Technical Data Rev. 5, 02/2013 An Energy Efficient Solution by Freescale © 2010-2013 Freescale Semiconductor, Inc. All rights reserved. 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. The MMA8453Q has user selectable full scales of ±2g/±4g/±8g. 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 3 mm by 3 mm by1 mm QFN package. 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 •I2C digital output interface (operates to 2.25 MHz with 4.7 k Ω pullup) • 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 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) ORDERING INFORMATION Part Number Temperature Range Package Description Shipping MMA8453QT -40°C to +85°C QFN-16 Tray MMA8453QR1 -40°C to +85°C QFN-16 Tape and Reel 16 PIN QFN 3 mm by 3 mm by 1 mm CASE 2077-02 MMA8453Q Top and Bottom View Top View Pin Connections 1 2 3 4 59 10 11 12 13 14 15 16 8 7 6 VDDIO BYP NC SCL GND NC GND INT1 GND INT2 |
