◦ Gyroscope: ±125dPS-±2000 dPS, suitable for slight attitude and high-speed rotation detection

3.Self-developed CRT gyroscope self-calibration: automatically compensates for offset after welding, sensitivity error control ± 0.4%, avoids data drift caused by soldering, stability targets automotive gyroscope process

4.Excellent temperature resistance: ‑40 ℃ ~ + 85 ℃ wide temperature operation, low temperature drift value, stable data in high and low temperature environment

5. Ultra-low power consumption: multi-step power-saving mode to prolong the battery life of portable devices.

6. Hardware interface: I2C, dual-channel SPI, built-in independent OIS anti-shake interface;Package LGA-14 (2.5 × 3.0mm), compact size suitable for small device PCB layout

III. Main functions

1. Posture motion acquisition: real-time reading of equipment tilt, rotation, vibration, movement acceleration, angular velocity

2. Lens stabilization OIS / EIS: independent stabilization channel, provides motion data for the camera, realizes optical stabilization and electronic video stabilization

3. Motion event recognition: step counting, hand-raising wake-up, flip detection, fall monitoring, gesture sensing

4. Indoor positioning PDR pedestrian trajectory calculation: no GPS environment relying on inertial data to complete indoor navigation and positioning

5. Interrupt Trigger: Vibration, tilt, and standstill can trigger chip interrupts, the master controller wakes up as needed, and reduces the overall power consumption.

6. Multi-sensor timestamp synchronization, can be used to build a nine-axis attitude module with an external magnetic sensor
