content: Hi guys,I'm looking at the Spartan 7 series (https://www.xilinx.com/support/documentation/selection-guides/cost-optimized-product-selection-guide.pdf#S7), and it mentions the package option TQGA144.I can't for the life of me find any mention of a TQGA144 package anywhere on the internets. Now their TQG144 package is a TQFP144 (http://www.xilinx.com/support/documentation/package_specs/tq144.pdf). Is it reasonable to assume that the package will be the same? Also, does anyone have any data on availability?Thanks,David

content: There will be no Spartan 7devices in a QFP.The word from the Xilinx sales guys is prototype silicon next year and general availability in 2018. They are essentially low end Artix devices without transceivers.The pricing is still TBD (which is very dumb...)

content: TQGA144 should be TQFP144TQ = TQFPG = Lead freeA144 = 144pin (don't really know what dose 'A' stand for,I guess maybe it means 0.5mm pitch)

No one should be looking at Spartan-7 now unless they've already got contacts within Xilinx.Quote from: ehughes on October 12, 2016, 01:48:18 amThat's not what their documentation shows... but with prerelease stuff, who knows. Things can change week to week!Quote from: ehughes on October 12, 2016, 01:48:18 amI'll be more interested in pricing once they might actually start shipping these things!Quote from: gamalot on October 12, 2016, 02:28:24 amThe product brief says what the A means:Quote from: Xilinx

content: The ugly thing about the TQFP144 package is that it has only 72user I/O

content: I literally just met with an app engineer and I side sales guy. There is no real customer demand driving it and it is a useless package for a 28nm device. Things could certainly always change but I have gotten this from the horse's mouth.They want this to be low cost and high volume. The QFP is the S6 was not a popular package. The parts DIYer purchase is a noise bit.Just suck it up an design with a BGA. The 1mm pitch stuff is super easy to route.

content: Spartan-7 and also new Artix A12T, A25T device information is still under NDA for Early Access members. It is now possible to talk a bit in public, as Vivado 2016.3 does include Spartan-7 BSDL files in public distribution, but those devices are not enabled with standard full Vivado License.Distribution has been crying long for Spartan-7, finally it should come also, should be fast ramp-up, so expected general availability should be before 2018 for sure.TQFP package is of course nonsense for many use cases, except high volume products with very low PCB layer count. We prefer also of course BGA as it so much easier to assemble than QFP.A12T and A25T are just "4th Die" in Artix family, no new packages just bit price optimized, leakage/idle current little bit less, and only 2 GTP.
