Xtrinsic MMA955xL Intelligent
Motion-Sensing Platform
Motion-Sensing Platform
The MMA955xL device is a member of Freescale’s Xtrinsic family of intelligent
sensor platforms. This device incorporates dedicated accelerometer MEMS
transducers, signal conditioning, data conversion, and a 32-bit programmable
microcontroller.
sensor platforms. This device incorporates dedicated accelerometer MEMS
transducers, signal conditioning, data conversion, and a 32-bit programmable
microcontroller.
This unique blend transforms Freescale’s MMA955xL into an intelligent, high-
precision, motion-sensing platform able to manage multiple sensor inputs. This
device can make system-level decisions required for sophisticated applications
such as gesture recognition, pedometer functionality, tilt compensation and
calibration, and activity monitoring.

The MMA955xL device is programmed and configured with the CodeWarrior
Development Studio for Microcontrollers software, version 10.1 or later. This
standard integrated design environment enables customers to quickly
implement custom algorithms and features to exactly match their application
needs.

Using the master I

C port, the MMA955xL device can manage secondary
sensors, such as pressure sensors, magnetometers, or gyroscopes. This
allows sensor initialization, calibration, data compensation, and computation
functions to be off-loaded from the system application processor. The
MMA955xL device also acts as an intelligent sensing hub and a highly
configurable decision engine. Total system power consumption is significantly
reduced because the application processor stays powered down until
absolutely needed.

Hardware Features
•
Three accelerometer operating ranges:
– ±2 g suits most hand gestures (orientation detection and tilt control) and
– ±2 g suits most hand gestures (orientation detection and tilt control) and
freefall. For tap detection, ±4 g and ±8 g are supported.
– ±4 g covers most regular human dynamics (walking and jogging)
– ±8 g detects most abrupt activities (gaming)
– ±8 g detects most abrupt activities (gaming)
