digital accelerometer
MMA8453Q
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 ±2 g/±4 g/±8 g. 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 16-pin QFN, 3 mm x 3 mm x 1 mm package.
