WIZnet W5500 Ethernet Controller Datasheet V1.3
The document details the WIZnet W5500, an embedded Ethernet controller that integrates a full hardware TCP/IP stack with MAC and PHY layers. It supports protocols including TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, allowing users to implement network applications using simple socket programming.
The datasheet provides comprehensive information on the device's features, such as support for 8 independent hardware sockets, a high-speed SPI interface up to 80MHz, power-saving modes (Wake-on-LAN), and an internal 32KB buffer. It includes detailed pin descriptions, register definitions, electrical specifications, and application guidelines. This manual is written in Chinese.

Questions answered in these manuals
What is the maximum SPI clock frequency?
The theoretical maximum SPI clock frequency is 80MHz.
Does the W5500 support automatic polarity transformation (MDIX)?
No, it does not support automatic MDIX; users must use straight-through or crossover cables manually.
How many hardware sockets does the W5500 support?
It supports eight independent hardware sockets for simultaneous communication.
