How to Extend W5500 to Multiple Sockets on an Altera FPGA? Summary This project demonstrates a single-socket WIZnet W5500 interface implemented in Verilog for an Altera FPGA, using an SPI link described as operating at 80 MHz. For an Industrial IoT design, the single-socket control flow can be extended into a multi-socket architecture by adding per-socket contexts, centralized SPI arbitration, shared buffer-transfer logic, and independent recovery timers. The W5500 remains responsible for Ethernet and TCP/IP processing, while the FPGA manages deterministic application data and socket…
