3万 · 2021-1-29 17:56

MicrochipTechnologyInc.（美国微芯科技公司）今日宣布推出集成了两个10/100PHY的分立EtherCAT®从属控制器LAN9252。这款高度集成的器件配有两个10/100以太网收发器，同时支持光纤和铜线，并具备电缆诊断功能。LAN9252支持传统的主机总线和SPI/SQI™通信以及独立的数字I/O接口，令系统设计人员在执行实时EtherCAT通信标准时可以从多种单片机型号中灵活选择。此外，对于在工厂自动化、过程控制、电机/运动控制及物联网（IoT）工业以太网应用中使用EtherCAT的开发人员而言，LAN9252可以有效降低系统复杂性和成本。

LAN9252是集成了两路以太网PHY的2/3端口EtherCAT从控制器,包括了全双工100BASE-TX收发器和支持100Mbps (100BASE-TX),支持3个Fieldbus存储器管理单元(FMMU)和4个SyncManagers,主要用在马达控制,过程/工厂自动化,通信模块,接口卡,传感器,水和气动阀门系统等.
