The MMA9553LR1 is an Intelligent Sensor, incorporating dedicated accelerometer MEMS transducers, signal conditioning, data conversion and a 32-bit programmable microcontroller. This unique blend transforms device 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 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 I2C port, the device can manage secondary sensors, such as pressure sensors, magnetometers or gyroscopes.
