Product Summary

The MMA8452QR1 is a smart 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 allow for overall power savings relieving the host processor from continuously polling data. The MMA8452QR1 has user selectable full scales of ±2g/±4g/±8g with high pass filtered data as well as non filtered data available real-time. The device can be configured to generate inertial wakeup interrupt signals from any combination of the configurable embedded functions allowing the MMA8452QR1 to monitor events and remain in a low power mode during periods of inactivity. The MMA8452QR1 is available in a 3 mm x 3 mm x 1 mm QFN package. Applications include: eCompass applications, Notebook, eReader and Laptop Tumble and Freefall Detection, Shock and vibration monitoring, User interface.
