Xtrinsic Accelerometers

Xtrinsic Accelerometer MMA845xQ Family

Pin-compatible 14-, 12- and 10-bit accelerometers

Scalable Intelligence in Motion

Freescale’s Xtrinsic accelerometer MMA845xQ

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, the

MMA845xQ accelerometers have six user-

configurable sample rates that can be set over

a wide range of 1.5 to 800 Hz. The power

scheme 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.

Pin to pin compatibility with register map

alignment maximizes hardware re-use between

10-bit and 14-bit designs where there is zero

development cost to migrate from 10-bit

to 14-bit performance. The MMA845xQ

accelerometers are feature-rich with a wide

range of real-time motion detection such

as orientation, directional shake and tap,

jolt, freefall and pedometer applications.

The MMA8451Q contains the 14/8-bit FIFO

which holds up to 32 samples of either low

pass filtered (LPF) or high pass filtered (HPF)

data, depending on user selection. See the

MMA845xQ accelerometer family comparison

table for more details.

The Xtrinsic accelerometer

MMA845xQ family is hardware

and software compatible.
