Summary of BHI260AB ULTRA-LOW-POWER SMART SENSOR HUB
Bosch Sensortec’s BHI260AB is an ultra-low-power smart sensor hub combining a programmable 32-bit Fuser2 microcontroller, a 6-axis IMU (3-axis accelerometer and 3-axis gyroscope), and preloaded sensor-fusion software in a compact 44-pad LGA package. Configurable CPU modes (20 MHz/50 MHz), onboard SRAM/ROM, optional external Flash for XiP, multiple host interfaces (SPI/I2C), up to 25 GPIOs, and high-speed I/O make it suitable for always-on sensor processing with flexible connectivity and low power consumption.

- Up to 25 GPIOs
- 4-channel micro DMA controller
- 2-way associative cache controller
- Floating point unit (FPU) and memory protection unit (MPU)
- 44-pad LGA package
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.
