TCP/IP PHY Embedded Chip - WIZnet W5100

WIZnet’s W5100 is a full-featured, single-chip, Internet-enabled 10/100 Ethernet controller designed for embedded applications where ease of integration, stability, performance, area and system cost control are required. The W5100 has been designed to facilitate easy implementation of Internet connectivity without an OS. The W5100 is IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant.

The W5100 includes a fully hardwired TCP/IP stack and integrated Ethernet MAC & PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE which has been proven in various applications for several years. 16Kbytes internal buffer is included for data transmission. Loaded with features the W5100 is great for a number of applications, including home-network devices, serial-to-ethernet, USB-to-ethernet, security systems, building automation, embedded servers and more!

For easy integration, three different interfaces - direct, indirect bus, and SPI - are supported on the MCU side.

  • Support Hardwired TCP/IP Protocols : TCP, UDP, ICMP, IPv4 ARP, IGMP, PPPoE, Ethernet
  • 10BaseT/100BaseTX Ethernet PHY embedded
  • Support Auto Negotiation (Full-duplex and half duplex)
  • Support Auto MDI/MDIX
  • Support ADSL connection (with support PPPoE Protocol with PAP/CHAP Authentication mode)
  • Supports 4 independent sockets simultaneously
  • Internal 16Kbytes Memory for Tx/Rx Buffers
  • 0.18 μm CMOS technology
  • 3.3V operation with 5V I/O signal tolerance
  • Small 80 Pin LQFP Package
  • Lead-Free Package
  • Support Serial Peripheral Interface(SPI MODE 0)
  • Multi-function LED outputs (TX, RX, Full/Half duplex, Collision, Link, Speed)

TCP/IP PHY Embedded Chip - WIZnet W5100 Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

3 Soldering

Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.
See all skill levels


Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.
See all skill levels


Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Customer Comments

  • Hi, do I need to write any program on that chip? Or it has built in function to interface with MCU?

  • Why is cost so high when you can get these chips for $4 direct from site?
