ETH WIZ click

ETH Wiz click carries W5500, a 48-pin, 10/100 BASE-TX standalone ethernet controller with a hardwired TCP/IP Internet protocol offload engine, along with a standard RJ-45 connector. The W5500 module employs a variety of solutions to reduce the target MCU's memory load and enable a stable and secure Internet connection. High speed network communications are realized through an 80 MHz SPI interface. The module has 32KB of internal memory for TX/RX buffers. Reduced power consumption is achieved with Wake on LAN and power down modes. Automatic handshaking, retransmit on collision and automatic rejection of erroneous packets are also supported.

TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE supported.
Wake on LAN and power down modes supported.
32KB of internal memory for TX/RX buffers.
Uses 3.3V power supply only.
