The NXP MMA8452Q is a low-power, three-axis capacitive micromachined accelerometer with 12 bits of resolution, featuring:
Embedded functions with flexible user-programmable options, configurable to two interrupt pins
Embedded interrupt functions for overall power savings relieving the host processor from continuously polling data
User-selectable full scales of ±2g/±4g/±8g with high-pass filtered data as well as non-filtered data available real-time
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
