Project description

How to Build a Commercial FPGA Ethernet Architecture with W5500? Summary This project presents a Verilog-based interface between an FPGA and the WIZnet W5500 Ethernet controller. The published material identifies two principal RTL components: a W5500 initialization finite-state machine and an SPI transfer module. In a commercial FPGA design, the W5500 can provide Ethernet MAC, PHY, hardwired TCP/IP processing, eight socket contexts, and packet buffering, while the FPGA implements deterministic control, data acquisition, framing, and application-specific state machines. What the Project Does…
