Bosch Sensortec’s BHI260AB ultra-low-power high-performance smart sensor hub with integrated accelerometer and gyroscope

Bosch Sensortec’s BHI260AB is a family of ultra-low-power smart hubs consisting of Bosch Sensortech’s programmable 32-bit microcontroller (Fuser2), a state-of-the-art 6-axis IMU, and a powerful software framework containing pre-installed sensor fusion and other sensor processing software within a small 44-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 Arm® Cortex®-M0 MCU up to multicore application processors, while it can also run standalone when booting from an attached Flash memory. In combination with its wide connectivity and extendability, the BHI260AB becomes a versatile and ideal solution when it comes to always-on sensor processing at ultra-low-power consumption.
