Read the Spartan docs. For example, it is 3.3v but can drive a high enough Voh to meet 5v TTL input specs (~2.4v), and the inputs are also 5v tolerant. They might meet your requirements. Else, OC drives with a 5v pullup might work. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
