Smart Sensors
Combining state-of-the-art motion sensing with the powerful brains of an ARM® Cortex™ microprocessor core, ST’s smart sensors run all sensor-fusion related functions on board. They include a sensor-hub function to coordinate and synchronize additional sensors, including magnetic and environmental sensors.
Smart sensors are ideal for baseband chipsets that do not include a sensor coprocessor, minimizing application latency and energy consumption at the system level.
Sensors Hubs
ST’s sensor hub products combine state-of-the-art motion sensing with I²C, SPI master/slave interfaces and FIFO features. This enables the merging and synchronization of additional sensor inputs, including environmental sensors.
