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
