Overview
The W5100S-L, produced by WIZnet, is an embedded Internet controller designed to provide full hardwired TCP/IP stack functionality. This chip integrates a 10/100 Ethernet MAC and PHY, making it a one-chip solution for stable internet connectivity. It supports various protocols including TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE. The W5100S-L is compatible with SPI (Serial Peripheral Interface) and Parallel System Bus, allowing for easy connection to external microcontrollers. It is a low-cost upgrade to its predecessor, the W5100, and existing firmware for the W5100 can be used on the W5100S-L without modification.
