1. Introduction
WIZ820io is the internet offload network module that includes W5200 (TCP/IP
hardwired chip, include PHY), MAG-JACK (RJ45 with X’FMR) with other glue logics.
It can be used as a component and no effort is required to interface W5200 and
Transformer.
The WIZ820io is an ideal option for users who want to develop their Internet
enabling systems rapidly.
For the detailed information on implementation of Hardware TCP/IP, refer
to the W5200 Datasheet.
WIZ820io consists of W5200 and MAG-JACK.
