Xilinx Virtex-II Pro DDR400/PC3200 Memory Board

The ML361 Virtex-II Pro DDR400/PC3200 Memory Board provides a communications platform between a Virtex-II Pro FPGA and high-speed double-data-rate (DDR) memories with operating speeds up to 200 MHz. The ML361 has three major functions:

- Tests and verifies the interoperability of Virtex-II Pro devices with high-speed DDR memories

- Serves as a development platform for Xilinx and its customers to use for building memory controllers

-Provides a means by which Xilinx can demonstrate high-speed DDR memory interoperability
The ML361 demonstrates a 64-/72-bit interface to a 128 MByte, 200 MHz DDR SDRAM DIMM, a 72-bit interface to five 256 Mbit, 200 MHzDDR SDRAM components, and an additional 8-bit, 166 MHz interface to a 256 Mbit DDR SDRAM component on one of the top banks.

Features:

One Virtex-II Pro FPGA (XC2VP20FF1152-6)
One DDR SDRAM DIMM (MT4VDDT1664-AG-40BC3)
- 128 MBytes / 64-/72-bit data interface
