# Using W5300 with Virtex6 FPGA

## Question

Asked by EEProjs on 2013-10-29 in Ethernet Chips.

Hi.
I’m designing a FPGA based boards that will use W5300 as TCP/IP controller. The FPGA is of Xilinx Virtex 6 family.
My problem is that the Virtex 6 has no 3.3 I/O interface an it’s maximum I/O voltage is 2.5v.

I want to know

1. can I connect W5300 to Virtex 6 with out any level shifter?

2. Do you have other TCP/IP controller that supports 2.5v I/O interface?
