Looking to add reliable Ethernet connectivity to your embedded system? The W5500 by WIZnet is a hardwired TCP/IP embedded Ethernet controller that simplifies network integration, reduces processing load, and boosts performance. Whether you’re building industrial IoT devices, smart appliances, or remote monitoring systems, the W5500 is the perfect solution for stable, high-speed Ethernet communication.
🔍 What is the W5500 Ethernet Module?
The W5500 is a TCP/IP offload engine with an integrated 10/100 Ethernet MAC and PHY, allowing microcontrollers to communicate over Ethernet with minimal resource usage. It supports 8 independent sockets simultaneously, making it suitable for multi-connection network applications.
This chip handles the full TCP/IP stack (TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE) internally, offloading complex networking tasks from the host MCU. The SPI interface makes it easy to connect to popular microcontrollers like STM32, ESP32, AVR, and Arduino.
