ORCA fpga?

cadnewbie found a gem -

Don't have a lot of information on what you have in hand - but Lattice is now the company building the ORCA FPGA products, and developing new devices and families based on this technology. The history lesson is a bit long: ATT and Xilinx were once partnered for early XLX FPGAs, with ATT being a foundry source - at some point the partnership dissolved - and ATT created it's own family called ORCA( for Optimized Reconfigurable Component Array) - ATT spun off LUCENT (with microelectronics along for the ride) Lucent spun off AGERE (with microelectronics along, essentially this is AGERE) AGERE sold off the ORCA technology, along with ASIC technology used for high-end SERDES based FPSC, to Lattice Semiconductor. Lattice now builds and develops device families based on the technology acquired. So, I guess check the lattice website, at least you will find the datasheets for the device on the pcb, and software to design and develop these devices as well. Good luck with your project, I would suggest a call to your Lattice FAE -

If you are really interested, I have the old ORCA software for schematic entry using Workview (included). It may use a hardware key, I don't remember. I must have one around, but it may take a bit to find it. The software however, I have handy if you are interested.

But my advice is to toss the board and deny ever having found it. :)

Just a note to say we have 500 Lucent ORCA FPGAs on consignment sale,

Are the OR2T15 and OR2T40 fairly new chips or the obsoleted ones? I guess I don't really care as long as the tools that are available can still program them. If I train yourself with it, that's what really matters for me anyway.

Both of these chips were on our board designed in 1999 and they were not new chips then. But I don't know that they are obsoleted.

As to tools, you will need to check with Lattice. Lucent did not provide current tools for these parts. Lattice may cover them under their newer toolset, or may not...
