Just came back from distributor, here's some info to share with list.
1, got 50pcs of XC6SLX45-2FGG484C back and now in our inventory.
2, since this distributor currently doesn't want that what their name with connection to their current stocks publicly, so i can only share what p/n of Spartan-6 they have now:
a) XC6SLX16-2FTG256C, mp product, 1 tray with 90pcs
b) XC6SLX16-2CSG324C, mp product, 1 tray with 90pcs
c) XC6SLX45-2FGG484C, mp product, 0.5k, and another batch will be arrival in October
d) XC6SLX45T-2FGG484C, mp product, 1 tray ( not sure how many pcs )
above items, they will always keep at least one tray of safe stock in their warehouse excepts. This means we now can get them within 1~2 weeks with some paper works and their internal financial processes. Item c) they have firm customer here, so will always keep 0.5k saft stock in their warehouse. Spartan-6 series products started mp from this July. Due to initially tight supply of mp stage for global distributors everywhere, they recommended always book a set of tray request in advance. This is reasonable. Even if they wanted to book US Xilinx for stocks before, there's no bulks we can easily get other new p/n unless later mp situation are more clear and stable, and people can get them at Digikey or else. Or we have firm few qty on demand.
So just share this with whom wants to use Xilinx Spartan-6 at prototype stage.
