The SPI interface can operate at up to 80 MHz.
From: WIZnet W5500 Datasheet
How many hardware sockets does the W5500 support?
The W5500 supports eight independent hardware sockets.
Does the W5500 support automatic MDIX (auto‑crossover)?
No, the W5500 does not support automatic polarity reversal; a straight‑through cable must be used for connections to switches or routers.
