Xtrinsic MMA955xL Intelligent
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.
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
2
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
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)
• Integrated temperature sensor
• One slave SPI or I
2
C interface operating at up to 2 Mbps, dedicated to
communication with the host processor
.
Default value of the I
2
C, 7-bit
address is 0x4C. (This can be customized by firmware.)
• One master I
2
C interface operating at up to 400 kbps that can be used to
communicate with external sensors
• Eight selectable output data rates (ODR), from 488 Hz to 3.8 Hz (extending
farther from 3906 Hz to 0.24 Hz with MMA9559L Firmware version)
• 10, 12, 14, and 16-bit trimmed ADC data formats available
• 1.8 V supply voltage
• 32-bit ColdFire V1 CPU with MAC unit
• Extensive set of power-management features and low-power modes
• Integrated ADC can be used to convert external analog signals
• Single-Wire, Background-Debug Mode (BDM) pin interface
• 16-KB flash memory
• 2-KB Random Access Memory
• ROM-based flash controller and slave-port, command-line interpreter
• Two-channel timer with input capture, output capture, or edge-aligned PWM
• Programmable delay block for scheduling events relative to start of frame
• A 16-bit, modulo timer for scheduling periodic events
• Minimal external component requirements
• RoHS compliant (–40ºC to +85ºC), 16-pin, 3 x 3 x 1-mm LGA package

Software Features
This device can be programmed to provide any of the following:
• Orientation detection (portrait/landscape)
• High-g/Low-g threshold detection
• Pulse detection (single, double and directional tap)
• Tilt detection
• Auto wake/sleep
• Embedded, smart FIFO
• Power management
• Pedometer
A selection of the software features are included in the factory-programmed firmware for some devices. Users may add their own
features with user firmware.The power and flexibility of the embedded ColdFire V1 MCU core associated with the high perfor-
mance 3-axis accelerometer give new and unprecedented capabilities to the MMA955xL devices family.

The only difference between the various device configurations is the firmware content that is loaded into the flash memory at the
factory. The user still can add custom software using the remaining portion of flash memory.
The MMA9550L, MMA9551L, and MMA9553L devices can function immediately as they are. They have an internal command
interpreter and applications scheduler and can interact directly with the users’ host system.
The MMA9559L device provides the most flexibility and is for users who need to design their own control loop and system. The
device needs to be programmed with custom user code.
