Detailed Description:

MMA8451Q is a has 14 intelligent low-power resolution, three axis, capacitance decay mechanical acceleration sensor.

The acceleration sensor has rich embedded function, with flexible user programmable options, you can configure up to the two interrupt pins.

Embedded the interrupt function can save the power consumption of the whole, relieve the burden of main processor constantly polling data. At the same time have access to the function of the low-pass filter and high-pass filter data, the data needed for analysis can be reduced to the lowest level, so as to realize moving detection and rapid response.

The device can be configured to use any combination of configurable embedded function generates inertial awakens the interrupt signal, which makes MMA8451Q in monitoring events at the same time, in the stationary state keep in low power mode.


  • Power supply voltage: 1.95 V to 3.6 V
  • The interface voltage: 1.6 V to 3.6 V
  • Plus or minus/plus or minus 4 g / 2 g + 8 g dynamic range can be selected
  • Range of output data rate (ODR) : 1.56 Hz to 800 Hz
  • Noise: 99 mu g Hz /)
  • 14 and 8 bits of digital output
  • The I2C digital output interface (when Ω pull-up resistor is 4.7 k, the highest frequency of 2.25 MHz)
  • Suitable for seven interrupt sources of two programmable interrupt pin
  • Three motion detection embedded channel
  • Or free fall motion detection: 1 channel
  • - pulse detection: 1 channel
  • - shake detection: 1 channel
  • With a programmable lag compensation direction (horizontal/vertical) detection
  • Automatically wake up and sleep ODR can automatically change automatically
  • 32 samples FIFO
  • High-pass filter data output and by FIFO output separately
  • Since the detection of
  • Conform to the RoHS standard
  • Power consumption: 6 mu, 165 mu A

Typical applications:

  • Electronic compass application
  • Static direction detection (horizontal/vertical, up/down, left/right and front/back position identification)
  • Laptops, ebook reader and portable computer fell and free fall detection
  • Real-time direction detection, virtual reality and game 3 d user position feedback)
  • Real-time activity analysis (pedometer step count, for HDD free fall detection, conjecture sailing GPS backup)
  • Motion detection is suitable for portable energy-saving products (for mobile phone, PDA, game consoles, GPS auto sleep and auto wake up)
  • Shock and vibration testing (mechanical and electrical integration of compensation, shipping and warranty using the record)
  • User interface (by direction change menu scrolling, detect button to replace the label)
