GENERAL DESCRIPTION

The MC3635 is an ultra-low power,lownoise,integrated digital output 3-axis accelerometer with a feature set optimized for wearables and consumer product motion sensing.Applications include wearable consumer products,IoT devices,user interface control,gaming motion input,electronic compass tilt compensation for cell phones,game controllers,remote controls and portable media products.

Low noise and low power are inherent in the monolithic fabrication approach,where the MEMS accelerometer is integrated in a single-chip with the electronics integrated circuit.

In the MC3635 the internal sample rate can be set from 14 to 1300 samples/second.Specific tap or sample acquisitionconditions can trigger an interrupt to a remote MCU.Alternatively,the device supports the reading of sample and event status via polling.
