Description: USR-ES1 is embedded with Wiznet’s W5500 chip, and uses hardware logic gate circuits to implement the transport layer and network layer of the TCP/IP protocol stack (such as: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), and integrates Data link layer, physical layer, and 32K bytes of on-chip RAM are used as data receiving and sending buffers. Make the host computer main control chip only need to undertake the processing task of TCP/IP application layer control information. This greatly saves the workload of the host computer on data replication, protocol processing, and interrupt processing, and improves system utilization and reliability. During operation, users can use W5500 as a peripheral RAM of MCU, which is very simple. The external interface of W5500 is a general 80MHz high-speed SPI, which can be selected for different platforms to expand high-speed Ethernet solutions. Auto-negotiation LED status shows that the SPI interface is fast and stable. The size and pins are compatible with Wiznet's official module WIZ820io Features:1. 80MHz high-speed SPI interface2.
