spartan 6 max supporting memory capacity

Hello

I'm planning a design based on xc6slx25-2ft256, as it has 2 memory controllers, does it support 2 8gb ddr3 sdrams with x16 data width? 2GB totally.

Thanks.

Re: spartan 6 max supporting memory capacity

the mcb user guide will answer this: https://www.xilinx.com/support/documentation/user_guides/ug388.pdf

see page 9:

Up to four MCB cores in a single Spartan-6 device. Each MCB core supports:

4-bit, 8-bit, or 16-bit single component memory interface

Memory densities up to 4 Gb

Up to 12.8 Gb/s aggregate bandwidth

So 4GB is the max density.
