WIZ820io is a plug-in network module that offloads Internet tasks to a mini-board that includes WIZnet’s W5200 integrated circuit (TCP/IP hardwired chip + PHY), a mag-jack (RJ45 with transformer) and other peripheral logic.
Housed in a very small form factor (23mm x 25mm), WIZ820io can be used as a ready-made component for Internet-enabling a product or board to develop networked systems rapidly. WIZ820io contains WIZnet’s hardwired Ethernet stack IC W5200, which supports eight independent sockets simultaneously, and features a high-speed SPI interface, power-down mode, and Wake-On-LAN function. WIZ820io handles TCP, UDP, IP, ARP, ICMP, IGMP, PPPoE, and MAC protocols. The module supports half / full duplex operation, auto-negotiation and auto cross-over detection.
