MMA7455LT 3-Axis Digital Accelerometer

Freescale's multiple digital and analog 3-axis accelerometer

Freescale - MMA7455Freescale Semiconductor's MA7455LT 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. 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 three acceleration ranges (2g/4g/8g).

The MMA7455LT series includes a standby mode, which makes it ideal for handheld battery powered electronics.

  • Level detection for motion recognition
    • shock, vibration, freefall
  • Pulse detection for single or double pulse recognition
  • Selectable sensitivity (±2g, ±4g, ±8g) for 8-bit mode
  • Sensitivity (64 LSB/g @ 2g and @ 8g in 10-Bit mode)
  • Robust design, high shocks survivability (5,000g)
  • User assigned registers for offset calibration
