MMA8450Q, 3-Axis, 8-bit/12-bit Digital Accelerometer - Data Sheet		Data SheetsMMA8450QR1
MMA8450QT		pdf4609.14/13/2012
MMA8450Q - 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.

MMA8450QT		pdf39111/23/2013
AN4399 - AN4399: Three-axis accelerometers supplied for the consumer market are typically calibrated by the sensor manufacturer using a six-element linear model comprising a gain and offset in each of the three axes. This factory calibration will change slightly as a result of the thermal stresses during soldering of the accelerometer to the circuit board.

AN3917, Motion and Freefall Detection Using the MMA8450Q		Application NotesMultiplepdf30002/11/2010
AN3917 - The MMA8450Q has two (2) embedded functions for both Motion and/or Freefall along with a very flexible interrupt routing scheme. Motion is often used to simply alert the main processor that the device is currently in use. This can be accomplished with the Motion function and/or with the Transient funtion, described in AN3918.

AN3922, Data Manipulation and Basic Settings of the MMA8450Q with Driver Code		Application NotesMultiplepdf44923/4/2010
AN3922 - It is important to understand how to program the MMA8450Q to extract and manipulate the acceleration data. The MMA8450Q has many different features which include seven different sample rates, 28 different cut-off frequencies for the high pass filter, 3 different dynamic ranges with different sensitivities for 12-bit output data, 8-bit output data and 8-bit delta data (data that has been filtered through the high pass filter). It also has a 32 sample FIFO for collecting and storing data, which is the most efficient way to access the data for minimizing the I2C transactions. The manipulation of the data into different formats is important for algorithm development and for display.
