Bosch BHA260AB Ultra-Low Power Smart Sensor

Bosch BHA260AB Ultra-Low Power Smart Sensor offers a 1.8V operating voltage, <1 second calibration time, and up to 12 GPIOs. The BHA260AB features Bosch Sensortec's programmable 32-bit microcontroller (Fuser2), a 3-axis accelerometer, and a powerful software framework. The Fuser2 Core is able to operate at 20MHz (Long Run mode) and 50MHz (Turbo mode). Bosch BHA260AB Ultra-Low Power Smart Sensor is the ideal solution when it comes to always-on sensor processing at ultra-low power consumption.
