They can also run entirely standalone.

They are aimed at wearables, hearables, AR/VR devices and phones.

Bosch has created an open development platform for these devices. This includes a comprehensive integrated software framework in ROM, evaluation kits and a mb SDK.

To facilitate more complex processing tasks such as automated activity recognition and context awareness, the BHI260 and BHA260 sensor hubs feature “Fuser2” – a 32-bit floating point CPU with 256 kB on-chip SRAM. The CPU draws merely 950 µA at 20 MHz in the super-efficient ‘long run’ mode, and 2.8 mA at 50 MHz in the high performance ‘turbo’ mode. The processor delivers up to 3.6 CoreMark/MHz.

The new Bosch sensor hub family includes state-of-the-art 16-bit MEMS sensors, a 6-axis Inertial Measurement Unit (IMU) in the BHI260 or a 3-axis accelerometer in the BHA260. They provide extensive connectivity, up to 25 GPIOs for BHI260 and up to 12 GPIOs for BHA260, and support for integration of other sensor devices, including GNSS and various localization systems.

The smart sensor hubs are compact enough to easily fit into small products such as hearables and wearables. The BHI260 comes in a 44 pad LGA package and measures just 3.6 x 4.1 x 0.83 mm3. The BHA260 is packaged in a 22 pad LGA package and measures 2.7 x 2.6 x 0.8 mm3.
