5.3  SDRAM DDR Memory 

The XP provides 2 independent banks of 64MB of DDR SDRAM with the option of 128MB when devices 
become available. Two Micron MT46V16M16 devices are fitted and are organised as 4Mx16x4. These devices 
can be operated at between 75MHz and 133MHz and depending on resource usage within the FPGA, a 
2VP70 can easily achieve 100MHz (DDR200) operation. Both banks are driven from Bank2 of the V2Pro.

The pins required for the SDRAM controller for each bank are listed below. 

 

 

 
The DDR controller uses SSTL1 IOB’s for data and control and SSTL1 for address and clocks - Please refer to 
the UCF for locations of the DDR pins. Please note that the FPGA requires the Vref pins to be connected for 
correct data reception on bank 3 when using SSTL standard. Additionally, bank 4 Vref pins connect to board 
Vref but are not required for user applications. These pins should not be configured with pull-up or pull-down 
options otherwise the Vref level will be set incorrectly. 
 
The XP is designed to support DDR interface cores supplied by Xilinx using 90 degree phase shifted clocks for 
DQS during write operations. This requires DQS pins occupy IOB’s that do not share a clock signal with DQ 
pins. In the XP, DQS[0:1] and DQS[2:3] occupy pairs of IOB’s sharing a common clock. Note A trace delay 
has been incorporated on the DQS lines of approx 1.5ns to allow the use of  local clocking within the FPGA
