Which affordable FPGA has the most dual port block-ram type resources in a TQFP144 or smaller quad flat pack (non-BGA) package, that's actually stocked by distributors?
I/O requirements and internal logic are fairly limited, but I need a lot of buffer memory and to fit the device on a very narrow PCB without the assembly issues of a BGA package.
So far spartan XC3S200 or XC3S250E with 12 x 16K-bit block rams seems the largest memory in a device that fully meets this constraint.
I'd really like the 16 block rams of the 400 or 500 gate parts or more, but squeezing in the PQFP-208 they come in is going to be dicey, and I'd like to avoid going to a BGA package.
Altera does not seem to offer the mid-size cyclones in quad flat packs, or at least they aren't stocked.
Any other makers with interesting parts?
