W5100S integrates the Hardwired TCP/IP stack with 10/100 Ethernet MAC and PHY, it is truly the one-chip solution for stable internet connectivity. WIZnet’s hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE - and it has been proven through various applications over the last decade. W5100S provides internet connectivity to your embedded system by using SPI (Serial Peripheral Interface) or Parallel System BUS.

​

W5100S provides four independent SOCKETs to be used simultaneously and a 16KB internal memory for data communication. W5100S also provides WOL (Wake on LAN) and a Power Down Mode in order to reduce power consumption.

​

W5100S is a low-cost chip that exceeds its predecessor, W5100. Existing firmware using W5100 can be used on W5100S without modification.
