Key Specs:

• Current consumption: typ. 925 μA (accelerometer and gyroscope in full operation)
• Step detector / significant motion: 5 μA each in the key features list (the general description states less than 30 μA)
• FIFO: 1024 bytes, allocatable across accelerometer, gyroscope and external sensors
• Sensor time-stamp resolution: 39 μs
• NVM data retention: 10 years min (T = 85 °C, after 15 cycles)
• Interfaces: I²C or SPI primary, secondary interface for magnetometer or OIS

Features:

• Hardware-synchronized accelerometer and gyroscope
• Built-in power management unit with gyroscope fast start-up mode
• Android Lollipop compatible: significant motion, step detector and step counter
• Hardware sensor time-stamps for sensor data fusion
• On-chip interrupt engine for autonomous motion detection (any-motion, no-motion, tap, orientation, free-fall, shock)
