用于移动设备的三轴电子罗盘 符合I3C总线接口
AK09919C
符合I3C总线接口 FIFO16步
AK09919C是AKM前一代产品AK09918C的向上兼容版本。AK09919C保持了AK09918C的尺寸和引脚兼容性，同时增加了I3C总线接口和FIFO16步等新功能。
AK09919C封装是0.4毫米间距的WL-CSP。尺寸为0.76 x 0.76 x 0.5毫米，由4个引脚组成：2个引脚用于供电，2个引脚用于I3C/I2C通信。
微型封装
面向智能手机的三轴电子罗盘
AK09918C
AK09918C在保持前一代产品AK09916C的高性能的同时，使用了我们有史以来最小封装 (0.76mm×0.76mm×0.5mm)，仅是前一代产品AK09916C的面积的63%。
封装为4引脚WL-CSP (2个电源引脚和2个I2C通信引脚)，引脚间距为0.4mm。
