What's the difference between Altera EPM1270T144C5 and EPM1270T144C5N?

From a search on Altera.com for RoHS, the "lead free" page (2nd hit) came up with:

A partial list of Altera's available lead-free devices is shown in Table 1. Lead-free components are denoted by an "N" suffix at the end of the part number, e.g., "EP1C12F324C6N".

It's a sincere disappointment that the part numbering guide on their site doesn't include the "N" i nthe "Suffixes" section.

You are correct. The "N" suffix does designate Altera's lead-free devices and our website does not explain this. I will make sure that this is corrected.
