WIZnet W5500 LQFP-48 TCP/IP Ethernet Controller Chip

The WIZnet W5500 Ethernet Controller Chip is a high-performance, hardwired TCP/IP embedded network chip that provides stable and fast Ethernet connectivity for various embedded systems. With an integrated MAC and PHY layer, the W5500 supports standard communication protocols such as TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, reducing the need for complex protocol software on the host microcontroller. Designed in a compact LQFP-48 package, it is ideal for industrial automation, IoT gateways, and embedded network applications requiring reliable Ethernet performance.

The chip offers a high-speed SPI interface that allows microcontrollers to communicate efficiently, offloading the entire TCP/IP stack to the hardware layer. With 32KB internal transmit and receive memory, it provides a simple yet powerful networking solution for both hobbyists and professional developers. The W5500 is fully compatible with 10/100 Mbps Ethernet standards and ensures stable operation with low power consumption.
