MMA8453Q, 3-axis, 10-bit/8-bit 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.
