Network Modules
W5500-io is a compact size network module that includes a W5500 (TCP/IP hardwired chip and PHY embedded).It can be used as a component and no effort is required to interface W5500. The W5500-io an ideal option for users who want to develop their Internet enabling systems rapidly. W5500-io is hardware compatible with W5100s-io and W6100-io.



The W5500-io Network Module is a compact, plug-and-play solution that offers an efficient way to add Ethernet connectivity to your projects. Featuring the W5500 chip—a hardwired TCP/IP controller with an embedded PHY—this module is designed for developers seeking a fast and straightforward method to integrate internet functionality into their systems. Key Features and Benefits: Streamlined Integration: Directly useable as a component, the W5500-io simplifies the process of integrating Ethernet connectivity, eliminating the need for complex hardware interfacing with the W5500 chip. Broad Compatibility: The module is hardware compatible with the W5100S-io and W6100-io, ensuring a seamless upgrade path or cross-compatibility with other network modules from WIZnet, allowing for flexibility in design and future expansions. No Hardware Design Required: It enables users to incorporate the W5500 without specific hardware design requirements for the W5500 itself, significantly reducing development time and complexity. Rapid Evaluation and Development: The W5500-io supports fast evaluation with an MCU on the target board, facilitating quick prototyping and testing of network functionalities in your designs. High-Speed Communication: With support for a high-speed SPI interface, the module ensures efficient data transfer between the MCU and network, incorporating features such as power-down mode and Wake-on-LAN to optimize power management. Compact Design: Its very small form factor, measuring just 20mm x 24mm x 2.6mm, makes the W5500-io particularly suitable for projects where space efficiency is crucial.
