MMA8452QR1 Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper initialization of the device.
  • The interrupt signals (INT1 and INT2) are active-low and open-drain. You should use an external pull-up resistor to connect them to a microcontroller or other logic device.
  • The SELFTEST pin is used to perform a self-test of the accelerometer's internal circuitry. When set high, the device performs a self-test and reports the result in the STATUS register.
  • The 14-bit acceleration data is represented as a signed integer, with a sensitivity of 1 LSB = 0.061 mg. To convert to units of g, multiply the 14-bit value by 0.061 mg/LSB and divide by 1000 to get g.
  • Keep the device away from high-current carrying traces and components, and avoid running sensitive analog signals near the device. Use a solid ground plane and decouple the power supplies with capacitors.
