Product Overview
The MEMSIC MXC6245XU is a high-accuracy, 2-axis accelerometer with a 1mg resolution and an I2C interface. It features a 2g full-scale range, 1mg/LSB resolution, and low offset drift over temperature. Utilizing MEMSIC's proprietary thermal accelerometer technology, it offers exceptional robustness, shock survivability (50,000g), and immunity to stiction and mechanical resonance, making it ideal for harsh or high-vibration environments. The device includes built-in orientation detection and operates from a 2.7V to 5.5V supply in a compact 6-pin ceramic LCC package. Applications include car navigation, projector auto keystone correction, DSC horizontal position detection, and inclination sensing.
