对于物联网产业MCU和EtherCAT齿轮
数以百万计的世界各地的工厂和加工厂的控制和处理节点、工业控制自动化是物联网（IoT）的下一个前沿和32位的MCUs将发挥重要作用。
以太网是连接制造节点创建一个工业物联网的显而易见的选择（IIoT）。通过采用以太网技术，工厂的地板可以无缝集成到企业，这将允许更快的制造响应不断变化的业务条件，集中维护和诊断，以及卓越的工厂自动化一般。
However， standard Ethernet falls short of the criTIcal factory-automaTIon requirements for two basic reasons：
Its MAC layer does not support real-TIme， low-latency data transfers. Standard Ethernet works for IT because it lets individual nodes take control of the network and transmit relaTIvely large packets of data. Control networks common in industry need deterministic transfer of relatively small amounts of control or status data.
Its star， switch-based topology is very dissimilar from networks found in manufacturing and processing plants.
To solve these problems， over 2，600 companies have endorsed EtherCAT （Ethernet for Control Automation Technology）， which adds real-time and other capabilities to classic Ethernet and enforces configurations that make it a very efficient automation network technology while fully conforming to Ethernet specifications. The EtherCAT Technology Group maintains the standard， which is part of the International Electrotechnical Commission （IEC） body of standards.
