Introduction

AI Translation

The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems. W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC and PHY embedded.

WIZnet‘s Hardwired TCP/IP is the market-proven technology that supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols. W5500 embeds the 32Kbyte internal memory buffer for the Ethernet packet processing. If you use W5500, you can implement the Ethernet application just by adding the simple socket program. It’s faster and easier way rather than using any other Embedded Ethernet solution. Users can use 8 independent hardware sockets simultaneously.

SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The W5500’s SPI supports 80 MHz speed and new efficient SPI protocol for the high speed network communication. In order to reduce power consumption of the system, W5500 provides WOL (Wake on LAN) and power down mode.

Product FAQ

  • 1. Is the W5500 Compatible With 5V Microcontrollers?
    Yes. The W5500 operates on a 3.3V supply but its I/O pins are 5V tolerant, so it can interface directly with 5V microcontrollers (such as traditional Arduino boards) without external logic level shifters
  • 2. What Should I Look for in an Alternative to the W5500?
    A drop-in replacement should offer an integrated Ethernet MAC and PHY, a standard SPI host interface, and a similar hardwired TCP/IP stack to avoid extra software overhead. Note that alternative chips may use different pinouts and require updated software libraries, since the W5500's register map and SPI frame format are specific to WIZnet's implementation.
  • 3. In What Application Scenarios Is the W5500 Typically Used?
    The W5500 is commonly used in home network devices (set-top boxes, PVRs, digital media adapters), serial-to-Ethernet and parallel-to-Ethernet converters, USB-to-Ethernet and GPIO-to-Ethernet adapters, security systems (DVRs, network cameras, kiosks), factory and building automation, medical monitoring equipment, and embedded servers.
  • 4. What Core Network Protocols and Memory Does the W5500 Support?
    The W5500 has a hardwired TCP/IP stack supporting TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE. It includes 32KB of internal memory for Ethernet packet buffering, supports 10BASE-T and 100BASE-TX speeds, and can manage up to 8 independent hardware sockets simultaneously.
  • 5. How Do I Connect the W5500 to a Host MCU, and What Power-Saving Features Does It Offer?
    The W5500 offloads the entire network stack to hardware, so connection is straightforward: wire your MCU to the W5500 via SPI and use a simple socket library to send and receive data. The SPI interface is rated up to 80 MHz in theory, though WIZnet's tested and guaranteed minimum clock speed is 33.3 MHz for stable operation; actual achievable speed depends on PCB trace length and signal integrity. For power-sensitive designs, the W5500 also supports Wake on LAN over UDP and a power-down mode.
