MEMSIC MXC3638AL 3-Axis Automotive Grade Accelerometers
MEMSIC MXC3638AL 3-Axis Automotive Grade Accelerometers are ultra-low-power, low-noise, integrated digital output accelerometers. Low noise and power are intrinsic in the monolithic fabrication process, where the MEMS accelerometer is incorporated in a single chip with the electronics integrated circuit.
The MEMSIC MXC3638AL internal sample rate can be set from 14Hz to 1300Hz. Specific tap or sample acquisition conditions can trigger an interrupt to a remote MCU. Alternatively, the device supports the reading of a sample and event status through polling.
