KMX65-1086
MEDIUM-G / WIDE BANDWIDTH TRI-AXIS MAGNETOMETER / TRI-AXIS ACCELEROMETER - KMX65-1086

The KMX65 is a 6 Degrees-of-Freedom inertial sensor system consisted of a tri-axial magnetometer, tri-axial accelerometer, and a temperature sensor coupled with an ASIC. The ASIC features flexible user-programmable ±8g / ±16g / ±32g / ±64g full scale range for the accelerometer and ±800μT / ±1200μT full scale ranges for the magnetometer. A highly configurable 512-byte FIFO buffer can be used to store output data from any of the sensors, with an option to limit the data to specific axes. The output buffer continuous to log data even when the output data is accessed and transmitted to the application processor via supported I2C and SPI digital protocols. The KMX64 also comes with an integrated wake-up and back-to-sleep digital engines with ultra-high resolution as well an embedded Free fall detection algorithm. The complete system comes in a 3 x 3 x 0.9 mm Land Grid Array (LGA) package operating from a 1.7V – 3.6V (VDD) / 1.7V - 3.6V (IO_VDD) DC supplies.

Highlights

  • Up to ±1200µT full scale range
  • Up to ±64g full scale range
  • Frequency response up to 8.5kHz
  • User-configurable Output Data Rate: up to 25.6kHz (accel)/12.8kHz (mag) with improved accuracy over temperature
  • Digital I2C up to 3.4MHz and Digital SPI up to 10MHz
  • Wake-Up/Back-to-Sleep engine with resolution of 0.977mg/count (accel) and 0.024μT/count (mag)
  • Embedded temperature sensor
  • Integrated Free fall algorithm
  • Highly-configurable 512-byte FIFO, with option to select the type of sensor and specific axis data to be stored. FIFO continues to record data even when being read
  • Excellent noise performance with bias stability over temperature
