USR-ES1 embeds Wiznet W5500 chip, uses hardware logic gate circuit to realize the transport layer and network layer of TCP/IP protocol stack (such as: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE and other protocols), and integrates The data link layer, physical layer, and 32K bytes of on-chip RAM are used as data sending and receiving buffers. The main control chip of the host computer only needs to undertake the processing task of the control information of the TCP/IP application layer. This greatly saves the workload of the host computer for data replication, protocol processing and interrupt processing, and improves system utilization and reliability.
During the operation, the user can use the W5500 as a peripheral RAM of the MCU, which is very easy. The external interface of W5500 is a general 80MHz high-speed SPI, which can be used by different platforms to expand high-speed Ethernet solutions. The auto-negotiation LED status shows that the SPI interface is fast and stable.
Dimensions and pins are compatible with the official Wiznet module WIZ820io
Note: This module is not an SPI-to-Ethernet transparent transmission module, it needs to be used by an external microcontroller, and the user needs to understand the use of the W5500 chip.
