Bosch BMI323

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 accelerometer, and a 16-bit digital temperature sensor in a miniature 2.5 x 3.0 x 0.83 mm³ (14-pin) LGA package.

• A self-calibrating gyroscope using motionless CRT (component re-trimming) functionality to compensate MEMS typical soldering drifts, ensuring postsoldering sensitivity errors down to ±0.7%
• 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
• A 2x8 on-chip FIFO buffer and provides synchronized data
• Supports motion detection, step detector, plug 'n' play step counter, orientation, flat-single tap, double tap, triple tap detection for always on applications
