MC3479 - MEMSIC

MC3479 Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the MC3479?
  The recommended power-on sequence is to apply VDD first, followed by VLOGIC. This ensures that the internal voltage regulators are powered up correctly.
• How do I configure the MC3479 for low-power mode?
  To configure the MC3479 for low-power mode, set the LPEN pin high and ensure that the ODR (Output Data Rate) is set to a low value (e.g., 10 Hz). This reduces the power consumption of the device.
• What is the maximum acceleration range that the MC3479 can measure?
  The MC3479 can measure accelerations up to ±8g. However, the device can be configured to measure higher accelerations (up to ±16g) by adjusting the sensitivity setting.
• How do I interface the MC3479 with a microcontroller?
  The MC3479 can be interfaced with a microcontroller using the SPI or I2C interface. The device can be configured to operate in either 3-wire or 4-wire SPI mode, or in I2C mode.
• What is the purpose of the SELFTEST pin on the MC3479?
  The SELFTEST pin is used to initiate a self-test sequence, which checks the internal functionality of the accelerometer. This pin should be tied low during normal operation.
