GENERAL DESCRIPTION The MXC3420AL is a small form factor, integrated digital output 3-axis accelerometer with a feature set optimized for industry applications, likes industry automatic control, device motion and tilt monitoring, remote controls, robot controls, etc. The MXC3420AL features a dedicated motion block which implements algorithms to support “any motion” and shake detection, tilt/flip and tilt 35 position detection. Low power consumption and small size are inherent in the monolithic fabrication approach, where the MEMS accelerometer is integrated in a single-chip with the electronics integrated circuit. In the MXC3420AL the internal sample rate can be set from 128 to 1024 samples / second. The device supports the reading of sample and event status via polling or interrupts.
