W5500 Ethernet Network Module, Full Hardware TCP/IP Protocol SPI Interface for Arduino

The W5500 Ethernet Network Module brings full hardware TCP/IP protocol support to your microcontroller projects, making it a dependable choice for embedded networking. Designed to work with popular platforms such as Arduino, STM32 and 51 series microcontrollers, this module handles the network stack in hardware, freeing your main processor for other tasks. It connects via the SPI interface, which keeps wiring simple and integration straightforward. Hardware TCP/IP Stack and Connectivity The module supports a comprehensive range of hardwired protocols, including TCP, UDP, ICMP, IPv4, ARP, IGMP and PPPoE. This means the module can manage the complexities of network communication without burdening your microcontroller. It also supports eight independent sockets simultaneously, allowing multiple connections to be handled at once. Auto-negotiation is included for both full and half duplex modes at 10 and 100 Mbps, ensuring compatibility with a wide range of network equipment. Practical Features for Embedded Use A built-in 32 Kbytes of memory is allocated for TX and RX buffers, providing ample space for data handling during transmission and reception. The embedded 10BaseT and 100BaseTX Ethernet PHY removes the need for an external physical layer chip, reducing component count and simplifying your design. Power down mode is supported for energy-conscious applications, and Wake on LAN over UDP is available for remote wake-up functionality. The high-speed SPI interface supports modes 0 and 3, giving you flexibility when connecting to your chosen microcontroller. Integration and Usage This module is well suited to projects that require reliable network connectivity, such as data logging, remote sensing and IoT prototypes. Its straightforward SPI connection and hardware-based protocol handling make it an efficient option for developers working with Arduino, STM32 or 51 series boards. Please note that IP fragmentation is not supported, so packet sizes should be managed accordingly within your application.
