xupv2p ram
Hi,
I have XUPV2P board with Virtex2 Pro chip on it.
i want to use memory.
i can buy the following modules:
1.RAM PQI 256MB DDR PC3200 - 200/266/333/400 MHz
2.RAM Super Talent D27PB12C 512Mb DDR PC2700 - 266/333 MHz
can these modules be used with my board?
here is what Xilinx recommends:
https://www.xilinx.com/univ/xupv2p_supported_dimms.html
however there is application note XAPP549 which shows how to interface DDR2 SDRAM to Virtex2 Pro devices..
https://www.xilinx.com/support/documentation/application_notes/xapp549.pdf
But..the problem is DDR2 SDRAM is 240-pin module, while the DDR SDRAM is 184-pin module..
The XUPV2P board is equipped with 184-pin DIMM module that provides access up to 2GB DDR SDRAM.
now the question is: Can i use above mentioned DDR SDRAM modules with PC3200 and PC2700? and with the specified frequencies?
(as i think...if Xilinx has application note XAPP549 which connects DDR2 to Virtex@ Pro chip... then why not to connect the DDR with the same speed to Virtex2Pro, isnt it?)
thanks in advance
