KMX63-1055
Medium-g / Wide Bandwidth Tri-Axis Magnetometer/ Tri-Axis Accelerometer - KMX63-1055

The KMX63 is a 6 Degrees-of-Freedom inertial sensor system that features 16-bit digital outputs accessed through I²C communication. The KMX63 sensor consists of a tri-axial magnetometer plus a tri-axial accelerometer coupled with an ASIC. It is packaged in a 3 x 3 x 0.9 mm Land Grid Array (LGA) package. The ASIC is realized in standard 0.18 µm CMOS technology and features flexible user programmable ±8g/±16g/±32g/±64g full scale range for the accelerometer and a +/-1200 µT range for the magnetometer. Accelerometer and Magnetometer data can be accumulated in an internal 384 byte FIFO buffer and transmitted to the application processor.

FEATURES:

  • Ultra-low power: 1 µA typical in standby, 150 µA typical (accelerometer only), 295 µA typical (magnetometer only), and 395µA (operating, both magnetometer and accelerometer)
  • 3x3x0.9mm, 16-pin LGA package
  • 384-byte FIFO buffer with watermarking capability
  • User-selectable ± 8g, 16g, 32g, 64g full-sale accelerometer range
  • Signal Bandwidth (-3dB) up to 8kHz
  • ±1200µT total magnetometer measurement range
  • Embedded temperature sensor
  • Magnetometer user-selectable ODR from 0.781Hz to 1.6kHz
  • Accelerometer user-selectable ODR from 0.781Hz to 1.6kHz
  • Magnetometer algorithms for auto-calibration and MI rejection
  • Outputs with up to 16-bit resolution
  • Digital (I2C) Output
  • Communication Voltage between 1.2V and 3.6V, Supply voltages between 1.7 V and 3.6 V
  • Excellent bias stability over temperature. Bias errors resulting from assembly can be trimmed digitally by the user.
  • Embedded features: User-configurable motion wake-up, back-to-sleep, free fall, and magnetic field change detection
  • Programmable interrupt engine
  • Accelerometer and Magnetometer self-test function
