1. Introduction
© Copyright 2008 WIZnet Inc. All rights reserved
WIZ811MJ is the network module that includes W5100 (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 W5100 and Transformer. The WIZ811MJ 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 W5100
Datasheet.
WIZ811MJ consists of W5100 and MAG-JACK.
