The BMI323 is a general purpose, low-power Inertial Measurement Unit (IMU) that combines precise acceleration and angular rate (gyroscopic) measurement with intelligent on-chip motion-triggered interrupt features. The 6-axis IMU comprises a 16-bit triaxial gyroscope, a 16-bit triaxial accelerpmeter, and a 16-bit digital temperature sensor in a miniature 2.5 x 3.0 x 0.83mm3 (14-pin) LGA package.
BMI323 targets fast and accurate inertial sensing in all applications. It is an easy-to-use IMU with an integrated feature set.
The sensor features a self-calibrating gyroscope using motionless CRT (component re-trimming) functionality to compensate MEMS typical soldering drifts, ensuring post- soldering sensitivity errors down to + 0.7%.
BMI323 includes embedded gesture and activity recognition with an integrated plug-and-play step counter/detector, which is optimized for accurate step counting in wrist-worn devices. The IMU is well-suited for other types of wearable devices, such as hearables or smart fitness trackers and for other mobile devices.
