Product Overview
The W5500 chip is a hardwired TCP/IP embedded Ethernet controller that simplifies Internet connectivity for embedded systems. It integrates a full TCP/IP stack, 10/100 Ethernet MAC, and PHY in a single chip. With this module, users can add Ethernet capabilities to their microcontroller-based projects with minimal development effort.
This module is based on the WIZnet W5500 chip and includes an integrated hardware TCP/IP stack. It supports 10/100 Mbps transmission rates, includes a 32KB buffer for Tx/Rx, and provides sleep mode and Wake-on-LAN functionality.
