Freescale MMA865x Xtrinsic 3-Axis
10 or 12-bit Digital Accelerometers

Freescale's MMA865x Xtrinsic 3-Axis, 10 or 12-bit Digital Accelerometers are 12-bit (MMA8652FC) and 10-bit (MMA8653FC) low-power, low-noise accelerometers that offer a wide range of performance for portable devices. At only 2 x 2 mm, they have a 56 percent smaller volume than previous Freescale accelerometers, and with a 1 mm height are ideal for low-profile applications. The MMA865x accelerometers have greatly optimized the overall system power consumption to be best in class. The MMA865x 3-axis accelerometers have six user configurable sample rates that can be set over a wide range from 1.5 to 800 samples per second. The operating current is proportional to the sample rate. The power scheme contains normal mode and low-power operational modes. FIFO allows for smarter system power management that contributes over 96 percent savings of the system power consumption when using the i.MX processor.
