Geekcreit® W5500 Ethernet Module TCP/IP Protocol Stack SPI Interface IOT Shield

Introduction The W5500 is a full featured TCP IP embedded Ethernet controller that provides an easier Internet connection solution for embedded systems The hardware logic gates are used to implement the transport layer and network layer of the TCP IP protocol stack eg TCP UDP ICMP IPv4 ARP IGMP PPPoE and other protocols and integrated data link layer physical layer and 32K bytes of on chip RAM as data transceiving buffer The host computer main control chip only needs to undertake the processing task of the TCP IP application layer control information Thereby the workload of the host computer for data copying protocol processing and interrupt processing is greatly saved and the system utilization and reliability are improved Features 1 80MHz high speed SPI interface2 Built in hardware TCPIP protocol stack users need almost no knowledge of complex network protocols3 Support up to 8 Socket connections4 Support TCP UDP ICMP IPv4 ARP IGMP PPPoE protocol5 Integrated data link layer physical layer6 Support power down wake up7 Support high speed serial peripheral interface SPI mode 0 3 8 Internal 32K byte send and receive buffer9 Embedded 10BaseT 100BaseTX Ethernet Physical Layer PHY 10 Support auto negotiation 10 100 Based full half duplex 11 IP fragmentation is not supported12 3 3V working voltage I O signal port 5V withstand voltage13 LED status display full duplex half duplex network connection network speed active status 14 U
