Hey guys, I don't understand you... Lattice XP is far more advanced than this stuff, and around for almost a year now. OK, xilinx marketing is better but still ... nothing very exciting if one tries to be a bit objective. It looks to me that you are all a bit too much xilinx minded. I guess this S3-AN is a 2 die solution. As far as I know there is no 90nm flash/SRAM process around (except for Fujitsu then). Thus 2nd generation XP can be expected quite soon.

What is the real shipping status of the Lattice parts?

The flash is just for configuration. At least that's what the FAE told me, when i asked if there were at least a few blocks I could put user data into. So that would be one advantage of the Spartan-3AN.> What is the real shipping status of the Lattice parts?XPs are shipping, and in low quantities as well. Last time I asked my distributor, they had every part I asked for in stock. But it's been a while... -- My email address is only valid until the end of the month. Try figuring out what the address is going to be after that...

Tim, It's true, flash is only for configuration. But still this flash can be used as mirror for the EBR (no write back though). I'm using the XP6 in small volumes (50pcs). LT was something like 4wks. Not bad I believe.

So what is the technical advantage of Spartan-3AN? Here are but a few points to consider. * Spartan-3AN FPGAs offer significantly more in-system Flash memory, between 627K to 12,251K even after storing an uncompressed FPGA configuration bitstream. + Store two different FPGA configuration bitstreams o Dynamically select between the two from with the FPGA application using the MultiBoot feature o Fail-safe "live" in-system Flash updates + Code-shadow MicroBlaze code within the FPGA + Fully accessible from within the FPGA application * Spartan-3AN In-System Memory is extremely robust + Intended for use by the FPGA application, not just configuration + 100,000 erase/program cycles + 20 year data retention * Spartan-3AN FPGAs offer the power-saving Suspend mode + Retains FPGA configuration and application state + Fast response time * Spartan-3AN FPGAs have embedded 18x18 hardware multipliers ? I don't believe that XP parts have multipliers * Spartan-3AN FPGAs span a broader range of densities, up to 22.5K LUTs * Spartan-3AN FPGAs have more I/O, more I/O per package, up to 502 I/ O pins * Spartan-3AN FPGAs offer more on-chip RAM + More block RAM + More LUT RAM * Pin-compatible with select members of the Spartan-3A FPGA family + Architecturally identical to Spartan-3A FPGA family I wouldn't claim that either part is "instant on", although the Lattice XP part -- Steve Knapp

So if one places external flash alongside a 3A, (That flash being larger, or smaller, (or faster?) than the in-package Flash of 3AN) you get all the same Flash-access features ? -jg

You have many of the same Flash size advantages by connecting an external Flash to a Spartan-3A device. Obviously, however, it is no longer a single package. The Spartan-3AN In-System Flash memory requires no user-I/O pins. Instead, all access is through an internal design primitive called SPI_ACCESS. I should also mention that Spartan-3AN FPGAs still support _all_ the other Spartan-3A configuration modes (Master Serial, Master Parallel, Slave Serial, etc.). Spartan-3AN FPGAs exclusively offer the Internal Master SPI mode. -- Steve Knapp

Tim, From the press release: "Pricing and Availability Customers can immediately begin designing systems with Spartan-3AN FPGAs using the ISE� 9.1i design tool suite and Spartan-3 Generation library of application-specific IP. Engineering samples are shipping now for the XC3S200AN, XC3S700AN and XC3S1400AN devices with all five devices in production by Q3 2007. At customer production timeframes at the end of 2007, Spartan-3AN devices will offer designers over 4,000 logic cells and 195 I/O for USD $4.90*, resulting in the world�s first integrated FPGA offering 4Mbits of flash for under $5.00." *250k resale volume, 3S200AN-4FT256C We decided to try something different this time: have stock of the items noted on the shelf at the time of release. 200, 700, 1400 available now. Production orders for all five family members accepted by end of 2007. Austin
