Bosch Sensatec's BHI260AB and BHA260AB
Integration of coprocessors assisting the main processor


Mouser Electronics announced on the 8th that it is supplying Bosch Sensortec's ultra-low power smart sensors 'BHI260AB' and 'BHA260AB'.

BHI260AB and BHA260AB, designed for always-on sensor applications such as wearables, hearables, AR/VR devices, and smartphones, integrate a coprocessor that relieves the main processor of sensor processing tasks, thereby reducing power consumption and extending battery life.

The BHI260AB is equipped with a 6-axis gyroscope/accelerometer inertial measurement unit, while the BHA260AB is equipped with a 3-axis MEMS accelerometer. Both devices use Bosch Sensortec's 32-bit floating-point MCU Fuser 2 core and 256 kBytes of on-chip SRAM. The programmable Fuser 2 core consumes 950µA of power in 20MHz Long Run mode and 2.8mA in 50MHz Turbo mode.

The BHI260AB provides up to 25 GPIOs, while the BHA260AB provides up to 12 GPIOs. Both devices include a host interface configurable to SPI or high-speed I²C to enable power-efficient data transfer at data speeds up to 3.4 Mbit/s.

Mouser also offers shuttle boards. The BHI260 and BHA260 shuttle boards, available for order from Mouser, include external sensors that can be connected using jumpers on the PCB. The shuttle boards provide easy access to the sensor pins via simple sockets and can be connected to Bosch Sensortec application boards.
