# Interfacing Wiznet W5300 with a Spartan 3 FPGA?

## Question

Asked by qandeel fazal on 2020-01-14 in Ethernet Chips.

I have to interface Wiznet W5300 chip with a Spartan 3 FPGA for sending packets over Ethernet using the Hardwired TCP/IP feature of Wiznet. I am planning to interface using the direct/indirect bus of Wiznet W5300. Can anyone point me to some good and helpful sources that can help me in this regard since I am quite new to this. So far I have mostly come across Wiznet interfacing with FPGA using the SPI protocol.

Dear [@qandeel_fazal](https://maker.wiznet.io/u/qandeel_fazal)

Sorry, we have no FW code to control W5300 with FPGA.

Ok is there any tutorial explaining the memory structure and addressing of Wiznet W5300 in detail with examples? Like I want to know in detail what actually is T.M.S and W.M.S?
