WIZ812MJ 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 WIZ812MJ 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.
