Overview
The W5500 chip, produced by WIZnet, is a Hardwired Internet controller designed to integrate a full TCP/IP stack, enabling Internet connectivity for embedded systems. It utilizes the Serial Peripheral Interface (SPI) for easy connection with external microcontrollers, supporting clock speeds up to 80MHz. The W5500 is a one-chip solution that includes a 10/100 Ethernet MAC and PHY, making it a stable and efficient choice for internet connectivity. It has been proven through various applications over the last decade and supports protocols such as TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE.
