FPGA with 5V tolerant I/O

Postby Sleepwalker » Sun Dec 04, 2011 9:43 am

Can anybody suggest a good low cost FPGA development board that is suitable for use with 5V TTL signals? I know pretty much all of the modern FPGA's these days are low voltage stuff, but my intended application is for test equipment for use with TTL stuff. I'm totally new to FPGA and know almost nothing about them, I have a small amount of experience in PALs and GALs, so something with a good software package and lots of training material and examples would be nice.
Thanks in advance :)

KNJN has three boards with 5V tolerant IOs
Pluto (RS232)
Pluto-P (Parallel port)
Dragon (PCI)

The Papilio One (http://www.papilio.cc) can be kitted out with a I/O buffer wing (http://www.papilio.cc/index.php?n=Papil ... BufferWing) to interface with 5V TTL.

If you wire your own harness it could be added to pretty much any FPGA board.
