Hello,
no clue about what FlexRay is but..
The GPIO pins on a DE2 are 3.3V powered, so they can act as 3.3V LVCMOS/LVTTL pins. They can be in, out or inout pins, with optional tri-state or open-drain function. And a few other things.
That is to say, those pins can implement pretty much anything that uses 3.3V LVCMOS/LVTTL levels. But if you need something else than 3.3V, you need a transceiver.
There are SPI cores. Maybe there's a FlexRay core as well.

Hello rbugalho,
thank you very much for your reply.
I need to implement GPIO pins with 5V. I think, as you said, I need a transceiver. Do you know how the transceiver has to look like. I have no idea how to start this.
Thanks a lot!
