3D PLUS Introduces First Space Grade 72b Wide DDR2 3D2D4G72UB3478

It is particularly well suited for use in high reliability, high performance and high density system applications, such as space computing board to Interface directly with Xilinx Virtex FPGAs. The 3D2D4G72UB3478 is packaged in a 191 BGA available with lead-free or leaded balls.



This product is radiation tolerant and available in industrial and specific temperature range for high reliability space applications.



“3D PLUS is a world leading manufacturer of high performance Rad-Hard and Rad-Tolerant memory products for space applications. We have a longstanding relationship with Xilinx, Inc as one of their preferred Alliance Members for high performance memory solutions,” said Pierre-Eric Berthet, VP Marketing and Sales at 3D PLUS. “We are very excited to be able to offer the first space qualified wide data bus DDR2 Memory module targeted for Virtex-5QV FPGAs and DDR2 interface IP. The Virtex-5QV, which are Rad-Hard by design, is being rapidly adopted by the Space community. By coupling Xilinx Virtex-5QV FPGAs with 3D Plus’ 72bit DDR2 memory modules, our mutual customers are achieving the best computing performance for space qualified electronics”.



“The Virtex-5QV device is the first of its kind reprogrammable Single-Event-Upset hardened FPGA specifically designed to withstand the harshest radiation environments. Since introduced in July 2011, the Virtex-5QV FPGAs are being adopted by many space programs, utilizing the resource rich devices to build complex, high-performance space systems that can be reprogrammed and updated even after launch.” said, Yousef Khalilollahi, Xilinx Senior Director, Segments Marketing. “We are very pleased that our Alliance Member has introduced these 72bit DDR2 memory modules, which allows our customers to benefit from the full processing power of our space-grade FPGAs.”
