Xilinx (NASDAQ:XLNX) announced support for a 400 Mbps DDR2 SDRAM interface (DDR2-400) with its low-cost 90 nm Spartan(TM)-3A and Spartan(TM)-3AN FPGAs. Designers can download a free hardware verified reference design providing quick implementation of a 400 Mbps DDR2 SDRAM interface. DDR2 SDRAM interfaces are widely used in applications such as low-cost video and networking.
The 400 Mbps DDR2 memory interface reference design, including data capture circuitry and memory controller, is fully verified in hardware using Xilinx(R) Spartan(TM)-3A FPGA high speed grade (-5) devices. The hardware validation process was completed using a Spartan-3A FPGA Starter Kit board with (-5) devices which includes full characterization at different process corners, as well as temperature and voltage variations that meet commercial grade requirements.
The free 400 Mbps DDR2 SDRAM interface reference design for Spartan-3A and Spartan-3AN FPGAs, including graphic demo files, is available for immediate download. Users can purchase low cost kits with out-of-the-box guarantee to get to market faster. The Spartan-3A FPGA DDR2 SDRAM Interface Development Kit is immediately available for US$235. The Spartan-3AN Starter Kit that features DDR2 SDRAM interface support is available today for US$225.
