MEMSIC MC3632 3-Axis Accelerometer

MEMSIC MC3632 3-Axis Accelerometer is an ultra-low-power, low-noise, integrated digital output three-axis accelerometer with features optimized for wearables and consumer product motion sensing. The low noise and power of the MC3632 are inherent in the monolithic fabrication process, where the MEMS accelerometer is integrated in a single chip with the electronics integrated circuit.

The MC3632's internal sample rate can be set from 14 to 1300 samples/second. Specific tap or sample acquisition conditions can trigger an interrupt to a remote MCU. Alternatively, the device supports sample and event status reading via polling.

Applications for the MEMSIC MC3632 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.
