BMI261 is pin-to-pin compatible with BMI160 and BMI260.

SYSTEM COMPATIBILITY

BMI261 is designed for best fit into modern Android™

and SPI). Dual SPI configuration enables BMI261 to serve two

SPI-based modules supporting stereo or 3D camera operation.

performance and current consumption are stable over the entire

supply range. Typical current draw for BMI261’s accelerometer

and gyroscope at full ODR of 6.4 kHz is under 700 μA. By

enabling high output data rates with low current consumption,

smartphone manufacturers can avoid an unpleasant aliasing

effect – an effect that causes different signals to become

indistinguishable when sampled at lower ODRs.

BMI261’s low latency, minimal group delays and high-precision

time stamps on µs level substantially improve photo/video

quality in the context of optical and electronic image stabilisation

(OIS/EIS). Using BMI261 on the mainboard in dual interface

operation mode enables congruent HMI and OIS functions, such

as stabilized panorama photo panning and action video tagging.

BMI261 provides an intelligent power management system

enabling motion-triggered always-on features to run inside the

ultra-low power domain of the IMU. The host application

processor wakes up only on dedicated occasions, enabling a

maximized idle period for the main processor.

BMI261 features an improved embedded step counter and step

detector, an improved secondary interface for AUX or OIS

operation and manual or automatic in-use offset compensation.

BMI261 supports Android™ smartphone optimized interrupts

including:

- virtual & batch sensors for dynamic batching

- tilt / glance / pick up / wake up gesture

- significant motion, motion detect and stationary detect

- tap / double tap detection (as primary wakeup gesture)

- wrist tilt, raise to wake (as alternative wakeup gesture)
