MMA8451Q, 3-Axis, 14-bit/8-bit Digital Accelerometer - Data Sheet (REV 10.3 )
The MMA8451Q is a smart low-power, three-axis, capacitive micromachined accelerometer with 14 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. There is access to both low pass filtered data as well as high pass filtered data.

AN4074, Auto-Wake/Sleep Using the MMA8451, 2, 3Q - Application Notes (REV 1 )
AN4074: Accelerometers are commonly used in hand-held electronics and/or battery operated electronic devices. When designing in the accelerometer, battery power usage is often a critical feature which concerns many designers. This application note will explain the following: The Auto-Wake/Sleep feature, Description of the configuration procedure with example register settings and code.

AN4073, Using the 32 Sample First In First Out (FIFO) in the MMA8451Q - Application Notes (REV 1 )
AN4073: The MMA8451Q has a built-in 32 sample first in, first out buffer capable of storing 14-bit data or 8-bit data. The data can be high pass filtered or not depending on whether the HPF_OUT bit is set in the part. The FIFO is very beneficial for saving overall system power by putting the processor into sleep mode until it needs to process data from the accelerometer.

AN4070, Motion and Freefall Detection Using the MMA8451, 2, 3Q - Application Notes (REV 1 )
AN4070: The MMA8451, 2, 3Q has one (1) 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. The transient function has the option of disabling the high pass filter and can behave exactly like the motion detection.

AN4071, High-Pass Filtered Data and Transient Detection Using the MMA8451, 2, 3Q - Application Notes (REV 1 )
AN4071: The MMA8451, 2, 3Q has a built-in high-pass filter. In the MMA8451, 2Q the output data can go through the high-pass filter, eliminating the offset (DC) and low frequencies (well below the cutoff). Note that the MMA8453Q does not have the capability to read out data from the high-pass filter. The high-pass filter cutoff frequency can be set by the user to four different frequencies which are dependent on the Output Data Rate (ODR).

AN4069, Offset Calibration of the MMA8451, 2, 3Q - Application Notes (REV 1 )
AN4069: The MMA8451, 2, 3Q has a selectable dynamic range of ±2g, ±4g, ±8g. The device has eight different output data rates, selectable high-pass filter cutoff frequencies, and high-pass filtered data. The available resolution of the data and the embedded features is dependant on the specific device. The MMA8450Q has a different memory map and has a slightly different pinout configuration.
