The KMX62 is a 6 Degrees-of-Freedom inertial sensor system that features 14-bit digital outputs accessed through I2C communication. The KMX62 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 0.9mm Land Grid Array (LGA) package. The ASIC is realized in standard 0.18um CMOS technology and features flexible user programmable ±2g/±4g/±8g/±16g full scale range for the accelerometer and a +/-1200 uT range for the magnetometer. Accelerometer and Magnetometer data can be accumulated in an internal 384 byte FIFO buffer and transmitted to the application processor.
