飞思卡尔的Xtrinsic智能动作感应平台是Xtrinsic系列的智能传感器平台中的一员。该MMA9550/1的Xtrinsic智能运动传感平台结合了专用的MEMS加速度传感器，信号调理，数据转换，和一个32位可编程微控制器。有了这个独特的混合，它把飞思卡尔的Xtrinsic智能动作感应平台变成智能，高精度，动作感应平台，能够管理多个传感器输入。这MMA9550/1的Xtrinsic智能运动传感平台可以让复杂的应用，如手势识别，计步器功能，倾斜补偿和校准，和活动监视提供所需的系统级决策。FeaturesHardware

       

• Three accelerometer operating ranges:
  
         
  
  • ±2g suits most hand gestures (orientation detection and tit control) and freefall. For tap detection, ±4g and ±8g are supported.       
    
  • ±4g covers most regular human dynamics (walking and jogging)       
    
  • ±8g detects most abrupt activities (gaming)
    
         
  
• Integrated temperature sensor       
  
• One slave SPI or I2C interface operating at up to 2 Mbps, dedicated to communication with host processor. Default value of the I2C, 7-bit address is 0x4C. (This can be customized by firmware.)       
  
• One master I2C 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       
  
• 10, 12, 14, and 16-bit trimmed ADC data formats available       
  
• 1.8V 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       
  
• 16-bit, modulo timer for scheduling periodic events       
  
• Minimal external component requirements       
  
• RoHS compliant (-40 to +85ºC), 16-pin, 3 x 3 x 1-mm LGA package
  

Software

       

• 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
