Good day!We have question about EPF10K20RI240-4N. We bought this positions 3 time from other supplier (From Russia dist and from Philippines) Each time this positions don't work with voltage 5.0-V and work only with 3.3-V. It is mistake in official Data Sheet or other reason?
Altera website doesn't seem to list this device anymore - perhaps it is too old and has been EOL'ed. I think you should either contact the distributor or try to RMA the device to Altera (not sure if possible at this point of time).
