USR-ES1 W5500 chip embedded in Wiznet uses hardware logics gates to implement the transport layer and network layer of TCP/IP protocol stack (such as TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), it also integrates the data link layer, physical layer, and 32K bytes of on-chip RAM as the data sending and receiving cache. The main control chip of the upper computer only needs to undertake the processing task of TCP/IP application layer control information. Therefore, the workload of the upper computer on data replication, protocol processing, interrupt processing and other aspects is greatly saved, and the system utilization rate and reliability are improved. Size and pin compatible with Wiznet official module WIZ820io Note: Features: 80MHz high-speed SPI interfaceThe built-in hardware TCPIP protocol stack eliminates the need to master complex network protocol knowledge.Supports up to 8 Socket connectionsSupports TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPPoE protocols.Integrated data link layer and physical layerSupports power failure and wake-upSupports high-speed serial peripheral interfaces (SPI mode 0~3)Internal 32k bytes receiving and receiving cacheEmbedded 10BaseT/100BaseTX Ethernet physical layer (PHY)Supports automatic negotiation (10/100-Based full duplex/half duplex)IP Sharding is not supported.3.3V operating voltage, I/O signal Port 5v withstand voltageLED status display (full duplex/half duplex, network connection, network speed, active status)Ultra-small plug-in package for easy embedded applicationsProvides C application routines TCP/IP Ethernet Module Hot Products
