DDR2 & Cyclone II EP2C8

edit: to be clear, i mostly want to know: has anyone used ddr2 with an ep2c8 speed grade 8? I am currently evaluating the possibility of using DDR2 memory, one device with x16 bit wide bus run...

hi iztok,

i have 2 questions:

- what package are you using (tqfp, bga ?)

- what is the targetted clock frequency ?

regards.

We did not have a clear target, but I was able to compile a project without DMA at:

- CPU 60MHz (it may work at up to 75MHz)

- DDR 110MHz

I tried to compile a very minimal project (only cpu, ddr, uart) with a common CPU and DDR clock, the minimum frequency for the DDR is about 85MHz and I was able to compile the whole system at 87MHz (as far as I remember). But we did not conduct any tests we probably will.
