The MMA8450Q accelerometer is an intelligent low-power and noise, 3 x 3 x 1 mm capacitive micromachined accelerometer featuring 12-bits of resolution. This accelerometer is packed with many flexible user-programmable embedded functions that are available with two configurable interrupt pins. MMA8450Q has user-selectable full scales of ±2g/±4g/±8g and it is capable of measuring accelerations with an output data rate (ODR) of 400 Hz, 200 Hz, 100 Hz, 50 Hz, 12.5 Hz and 1.563 Hz. These output data rates correspond to sample intervals from 2.5 ms to 640 ms.
The device can be configured to generate inertial wake-up interrupt signals when a programmable acceleration threshold is crossed on any one of the three sensed axes. Acceleration and time thresholds of interrupt generators are programmable by the end user.
MMA8450Q is available in a plastic QFN package and is guaranteed to operate over the extended temperature range of -40°C to +85°C.
