W5500 Ethernet module

W5500 Ethernet module

The W5500 Ethernet module is a module that uses the hardware TCP/IP protocol stack chip W5500 as the main control to debug the transmission signals on the Ethernet and convert the signals into valid data that can be recognized and processed by the CPU. W5500 Ethernet module is a full hardware TCP/IP embedded Ethernet controller, which provides a simpler Internet connection method for embedded systems. It uses hardware logic gate circuits to realize 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 the data link layer, physical layer, and 32K bytes of on-chip RAM as a data transceiver buffer, so that the host computer control chip, only need Undertake the processing task of TCP/IP application layer control information. This greatly saves the workload of the host computer for data replication, protocol processing and interrupt processing, and improves system utilization and reliability.

Notes: Ethernet is a networking technology that connects computers by wire. It is the medium of direct connection between the computer and the Internet via a USB cable or an Ethernet cable. Communication between devices is possible via Ethernet.

● W5500 Ethernet Module Application Scenarios

W5500 Ethernet module application

Ethernet has a very wide and deep application in various fields and industries, which is mainly due to the high flexibility and easy implementation of Ethernet. Because Ethernet has the advantages of simple networking, low cost, excellent compatibility, reliable connection, and convenient topology adjustment, it has advantages that other network technologies do not have in terms of being a gateway for smart homes, IoT or wireless sensor networks. , which has been vigorously developed and applied.

The W5500 ethernet module is small in size and can be applied in a wide range of fields, such as computer, data acquisition, remote control network project transformation and other fields.
