Freescale Semiconductor, Inc.- 音频和信号处理组件

飞思卡尔半导体公司是一家曾经领先的美国半导体企业，于2004年从摩托罗拉的半导体产品部剥离成立。总部位于得克萨斯州奥斯汀，公司专注于为汽车、工业、消费和网络市场提供嵌入式处理与连接解决方案。其旗舰产品线包括基于Power Architecture的QorIQ和PowerQUICC通信处理器、面向多媒体与显示应用的i.MX应用处理器，以及用于低功耗嵌入式控制的Kinetis系列ARM Cortex-M微控制器。飞思卡尔还提供S12和MPC5xxx系列汽车微控制器、模拟与混合信号IC，以及包括加速度计和压力传感器在内的丰富传感器产品。公司以其深厚的系统级专业知识和超过一万种产品的庞大组合而著称。在鼎盛时期，飞思卡尔曾位列全球半导体供应商前15强，在汽车MCU和通信处理器领域占据强势地位。其技术推动了先进驾驶辅助系统、车载网络和物联网设备的发展。2015年，飞思卡尔被恩智浦半导体收购，两者合并成为汽车与安全连接解决方案的巨头。在此之前，飞思卡尔由多家投资机构组成的财团私人持有，年营收超过45亿美元。
