| Gyroscope range | Selectable ±125, ±250, ±500, ±1000, and ±2000 °/s |
| Sampling rate | Accelerometer ODR: 12.5 Hz–1.6 kHz; gyroscope ODR: 12.5 Hz–6.4 kHz |
| Output type | Game Rotation Vector; accelerometer and gyroscope data |
| Interface | Host SPI or I²C; two secondary master interfaces (one I²C and one selectable SPI/I²C); up to 14 GPIOs |
| Supply voltage | VDD: 1.71–3.6 V; VDDIO: 1.71–1.89 V |
| Dimensions | 2.5 × 3.0 × 0.95 mm³ package |
The official specifications list 16-bit accelerometer and gyroscope resolution, selectable output data rates of 12.5 Hz–1.6 kHz for the accelerometer and 12.5 Hz–6.4 kHz for the gyroscope, and Game Rotation Vector sensor-fusion output. Typical noise density is 160 µg/√Hz (8 g) or 170 µg/√Hz (28 g) for the accelerometer and 0.007 °/s/√Hz (performance mode) or 0.01 °/s/√Hz (normal mode) for the gyroscope. Soldered offset over life is ±25 mg (A) and ±0.5 °/s (G); TCO is ±0.25 mg/K (A) and ±0.015 °/s/K (G); sensitivity error is 0.4% (A) and 2% (G). Operating temperature is −40 to +85 °C. It includes self-learning AI and Motion AI Studio support.
