WIZnet W5100S Embedded Internet Controller Chip

WIZnet W5100S Embedded Internet Controller Chip is designed with hardwired Transmission Control Protocol (TCP) / IP and WIZnet technology. This controller chip supports full hardwired Ethernet Media Access Control (MAC), 10Base-T / 100Base-TX Ethernet PHY, and is a one-chip solution for internet protocol. The W5100S comes with SPI and a parallel system BUS interface for the host interface. This controller chip provides a low power / low heat design, Wake On LAN (WOL), and Ethernet PHY power down mode. 

The W5100S is a low-cost chip that improves on the W5100 Ethernet controller. Any firmware compatible with W5100 is compatible with W5100S without any modification. This W5100S controller chip is available in 48-pin Low-profile Quad Flat Package (LQFP) and Quad Flat No-leads (QFN) lead-free package. Typical applications include home network devices, serial-to-ethernet, parallel-to-ethernet, USB-to-ethernet, security systems, factory / building / home automation, and embedded servers.

Features

  • Supports hardwired IPs:
    • TCP, UDP, WOl over UDP, ICM, IGMPv1 / v2, IPv4, and PPPoE
  • Supports 4x independent sockets simultaneously 
  • Supports SOCKET-less command:
    • ARP-request and PING-request
  • Ethernet power down mode and main clock gating for power save
  • WOL over UDP
  • Serial and parallel host interface:
    • High-speed SPI (mode 0/3), system bus with 2x address signal, and 8-bit data
  • Internal 16Kb memory for TX / RX buffers
  • 10Base-T / 100Base-TX Ethernet PHY integrated
  • Auto-negotiation (full / half duplex, 10- and 100-based)
  • Auto-MDIX only on the auto-negotiation mode
  • 3.3V operation with 5V I/O signal tolerance
  • Network indicator LEDs (full / half duplex, link, 10 / 100 speed, and active)
  • 48-pin LQFP and QFN lead-free package (7mm x 7mm dimension and 0.5mm pitch)

Applications

  • User product based on W5100 with no modified firmware
  • Home network devices:
    • Set-top boxes, PVRs, and digital media adapters
