BHA250/ BHA250B Ultra low-power sensor hub incl. integrated Accel
■The BHA250(B) is a small, low-power smart-hub with an integrated three axis accelerometer plus a programmable microcontroller, all specifically designed to enable always-on motion sensing. On top it contains software and algorithms for motion-step-, gesture- and activity recognition. The overall concept perfectly matches the requirements of smartphones, wearables or any other application which demands highly accurate, real-time motion data at very low power consumption.
■The device integrates our millionfold proven 14bit acceleration sensor with a microcontroller – the new Bosch Sensortec Fuser core. It is bringing you the full Android sensor stack inside your devices – even without having an Android OS or an Android environment. Combining this with the built in computing power and the highly configurable on-board memory the BHA smart-hub offers you a low power solution for motion sensing and data processing.
●Features
■All-in-one smart-hub solution for always-on motion sensing at a fraction of current consumption which is commonly required using discrete components.
■32-bit floating-point microcontroller (Fuser Core). Optimized for data fusion, motion sensing and activity recognition at ultra low power consumption. All in order to offload the power hungry data processing from the main application processor to the smart-hub.
■Powerful BSX sensor fusion library integrated in ROM for lowest design-in effort and fastest time-to -market.
■Additional software and algorithms for RAM processing, provided as ready to use FW patch files. Visit our web site to check available downloads.

■Gesture recognition of significant motion, tilt, pickup, wake up and glance. Enabling customer specific gesture based HMI interfaces for smartphones and wearables.
■Activity recognition of standing, walking, running, biking and in vehicle. Enabling health & fitness applications or any other use case where highly accurate and reliable detection and/or monitoring of user activities is required.
■Step detection and step counting.
■Android 5 / L / Lollipop & Android 6 / M / Marshmallow (non-HiFi) support, incl. batching with dual FIFO buffer for wakeup and non-wakeup events. Implements the full Android sensor stack although an Android OS or any other Android environment is not required.
■High speed I2C interface, with data rates up to 3.4 MBit/s for power-efficient data transfer.
■Highly configurable internal RAM for either feature extension and/or FIFO data buffering.
■ SW / FW based functionality. Can be updated, optimized, customized or upgraded with totally new features to support future requirements.
■ Smart-hub plus microcontroller, MEMS sensors and software all highly integrated in one 2.2x2.2x0.95 mm3 LGA package with extension interface for additional sensors.
