Hi Group,

Could you guys please recommend me a non volatile fpga (which can hold
its bit stream in, an on-chip flash).
I might need to put a soft core cpu in the fpga as well. so a medium
size device like Spartan-3AN-700 will be fine for me. I am looking for
any device which is smaller in size than Spartan-3AN-700 which is
23mmX23mm. Xilinx Spartan 3AN devices have no variety available in
terms of same packages but with different CLB sizes.

Regards,

Asim

You should check out the Lattice XP2 series. They also offer
a 32-bit CPU development platform (Mico-32) and their chip
offerings are broader for non-volatile devices. If you're
tied to Xilinx, then 3AN is your only choice.

The usual suspects would be Lattice, Actel, SiliconBlue and if you
don't need it today ;) then even Menta who have a MRAM based FPGA
coming...

If you can shrink the fpga by avoiding the soft-cpu, then Cypress and
Actel have Arm+Logic solutions
