 II. Full Core Parameters

 1. Basic Physical and Electrical Parameters

- Package: LGA-14L, dimensions 2.5mm × 3.0mm × 0.83mm

- Supply Voltage: Analog main supply 1.71V ~ 3.6V; independent I/O supply 1.62V

- Operating Temperature: -40℃ ~ +85℃ (commercial-grade with general industrial temperature range)

- Communication Buses: I2C, SPI, high-speed MIPI I3C 1.1 interface; dedicated auxiliary SPI for OIS stabilization data output

- FIFO Buffer: Large 9KB buffer, greatly reducing MCU sampling load

- Power Consumption (Core Selling Point): Typical current of only 0.55mA when accelerometer and gyroscope operate synchronously in high-performance mode; supports Always-On low-power continuous detection

- Output Resolution: 16-bit ADC digital output for all channels

### 2. Sensing Full Scale and Accuracy

#### 3-Axis Accelerometer

- Software-selectable full scales: ±2g / ±4g / ±8g / ±16g

- Integrated hardware interrupt detection for step counting, free fall, tilt, single-tap and double-tap events

#### 3-Axis Gyroscope

- Selectable angular rate full scales: ±125 / 250 / 500 / 1000 / 2000 dps

- Maximum Output Data Rate (ODR): 6.66kHz

- Excellent mechanical shock resistance and outstanding attitude stability under vibrating conditions

### 3. Exclusive Features (Key Sales Highlights)

1. Embedded MLC Machine Learning Core + FSM Finite State Machine

Performs on-chip motion recognition, vibration judgment and attitude trigger events directly on the sensor, without consuming computing resources of the main STM32 MCU, simplifying flight control program development.

2. Independent Auxiliary SPI Channel for OIS

Gyroscope data is output via a separate SPI bus, directly interfacing with camera optical image stabilization modules, perfectly compatible with EIS/OIS for smartphones and aerial gimbals.

3. Abundant Hardware Interrupts

Supports free fall detection, 6D orientation detection, wake-up/sleep control, tap detection, activity and inactivity monitoring.

4. Sensor Hub Expansion Interface

External magnetometers and barometers can be connected to construct a complete 9-axis or 10-axis navigation system.

5. Compliance

RoHS compliant, ECOPACK eco-friendly package.
