Manual Click here to openOverview USR ES1 embeds Wiznets W5500 chip which uses hardware logic gates to implement the transport layer and network layer of the TCP IP protocol stack such as TCP UDP ICMP IPv4 ARP IGMP PPPoE etc and integrates The data link layer physical layer and 32K bytes of on chip RAM serve as data transceiving buffers 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 During operation the user can approximate the W5500 as a peripheral RAM of the MCU which is very simple The W5500 external interface is a general purpose 80MHz high speed SPI which is used to expand the high speed Ethernet solution for different platforms The auto negotiating LED status shows that the SPI interface is fast and stable Dimensions and pin compatible Wiznet official module WIZ820io Features 80MHz high speed SPI interfaceBuilt in hardware TCPIP protocol stack users almost no need to master complex network protocol knowledgeSupport for up to 8 Socket connectionsSupport TCP UDP ICMP IPv4 ARP IGMP PPPoE protocolIntegrated data link layer physical layerSupport power down wake upSupport high speed serial peripheral interface SPI mode 0 3 Internal 32K byte send and receive cacheEmbedded 10BaseT 10
