MMA8452QR1

The MMA8452QR1 is a smart low-power three-axis capacitive micromachined Digital Accelerometer with 12 bits of resolution. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. The MMA8452Q 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 wake-up interrupt signals from any combination of the configurable embedded functions allowing the MMA8452Q to monitor events and remain in a low-power mode during periods of inactivity.

• 12- and 8-bit digital output
• Two programmable interrupt pins for six interrupt sources
• Orientation (portrait/landscape) detection with set hysteresis
• Automatic ODR change for auto-wake and return to sleep
• High pass filter data available real-time
• Self test
