      MMA7455LT ACCELEROMETER 3AXIS LGA14 (Freescale Semiconductor)


      ±2g/±4g/±8g Three Axis Low-g 
      Digital Output Accelerometer

      ±2g/±4g/±8g Three Axis Low-g Digital Output Accelerometer

      The MMA7455L is a Digital Output (I2C/SPI), low power, low profile 

      capacitive micromachined accelerometer featuring signal conditioning, a low 

      pass filter, temperature compensation, self-test, configurable to detect 0g 

      through interrupt pins (INT1 or INT2), and pulse detect for quick motion 

      detection. 0g offset and sensitivity are factory set and require no external 

      devices. The 0g offset can be customer calibrated using assigned 0g registers 

      and g-Select which allows for command selection for 3 acceleration ranges 

      (2g/4g/8g). The MMA7455L includes a Standby Mode that makes it ideal for 


      handheld battery powered electronics.
