This device contains no moving sensor parts and thus eliminates field reliability and repeatability issues associated with competitive products. For example, there is no measurable resonance (immunity to vibration), no stiction, and no detectable hysteresis. It also eliminates the "click" sounds typically heard in ball based orientation sensors. Shock survival of the MEMS sensing structure is greater than 200,000g. This sensor provides X/Y/Z axis acceleration signals with very low 0g offset, and temperature signal with high accuracy. In addition, it detects six orientation positions, X/Y shake and shake directions.
采用0.18µm标准CMOS工艺的三轴加速度计，其中没有可移动传感器部件，从而大大提高了现场可靠性，消除了与竞争产品相同的重复性问题，确保传感器结构。对于冲击和震动有着超长的稳定性（可以承受200,000g的冲击而无传感性能的变化），可提供无偏差的X/Y/Z方向的信号，和高精度的温度信号，可检测6个方向的位置值，X/Y方向的震动及加速度值。可操作温度范围-40°C ~ +85°C。提供了I2C快速模式操作（≤400KHz），为方向和X/Y抖动检测提供了一个中断引脚（INT）。可通过I2C通讯进入掉电模式。
