    BHA260

    The BHA260 is a family of ultra-low power smart hubs consisting of Bosch Sensortec’s new, programmable 32-bit microcontroller (Fuser2), a state-of-the-art 3-axis accelerometer and a powerful software framework containing pre-installed sensor fusion and other sensor processing software within a small 22 pad LGA package.

    The Fuser2 Core is configurable to operate at 20 MHz (Long Run mode) and 50 MHz (Turbo mode). It can boot from a wide variety of hosts, ranging from a small Cortex-M0TM MCU up to multicore application processors. In combination with its wide connectivity and extendibility, the BHA260 becomes a versatile and ideal solution when it comes to always-on sensor processing at ultra-low power consumption.

    Applications

    - 24/7 always-on sensor processing at ultra-low power consumption

    - Power management and wake-up control, 3D orientation, step counting, activity recognition, pose and head tracking, context awareness

    - Wrist-mounted, hearables, eyewear and other wearable devices

    - Smartphones and other mobile communication devices

    - AR/VR/MR reality headset and controller devices

     
     

    Wearable Applications

    The new generation of Bosch Sensortec's smart sensor hubs BHI260 and BHA260 enables always-on sensor applications at ultra-low power. This significantly extends the battery life of wearable devices, such as hearables.

    Augmented & Virtual Reality Applications

    With the help of its integrated powerful sensor coprocessor and MEMS sensors, the BHI260 and BHA260 can handle sophisticated sensor processing tasks and data buffering without waking up the main application processor, and can even run entirely standalone. Their low power consumption translates into significantly extended battery lifetimes in e.g. AR/VR devices.
