Overview

The W5500 is a hardwired TCP/IP embedded Ethernet controller designed to provide easy internet connectivity to embedded systems using a Serial Peripheral Interface (SPI). It features a reinforced stack that supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols, significantly reducing the overhead on the host microcontroller.

Why Choose This Part

The hardware-based TCP/IP stack offloads network processing from the host MCU, allowing low-end microcontrollers to handle high-speed Ethernet traffic. It supports up to 8 independent sockets simultaneously and features a power-down mode and Wake-on-LAN to optimize energy efficiency.

Applications

Industrial Automation
Reliable wired networking for PLC and sensor gateway applications in high-noise environments.
IoT Gateways
Connecting local sensor networks to cloud services via a stable 10/100 Ethernet link.
Building Automation
Integrating HVAC and security systems into existing local area networks with minimal MCU resources.
Remote Monitoring
Providing persistent network access for remote data logging equipment where wireless is unsuitable.

Getting Started

Engineers typically begin evaluation using the W5500-EVB-Pico or the WIZ850io module. Integration involves connecting the SPI bus to a host MCU and using the WIZnet ioLibrary, which is compatible with many C-based environments and the Arduino Ethernet library.
