Freescale MMA845xQ Xtrinsic Accelerometers

Freescale Semiconductor MMA845xQ Xtrinistic accelerometer family offers extremely low power and pin compatibility with a broad range of resolution (14-, 12-, and 10-bit) and embedded features for configurable, accurate motion analysis. To operate with extremely low power, Freescale Semiconductor MMA845xQ Xtrinsic accelerometers have six user-configurable sample rates that can be set over a wide range of 1.5 to 800 Hz.

The power scheme of these Freescale accelerometers contains four different power modes from high resolution to low power, offering best-in-class savings in supply current and extremely high resolution for very small motion detection. MMA854xQ Xtrinisic accelerometers are ideal for mobile phones, laptops, unbalance detection for washers, and more.
