Cypress Semiconductor announced Altera has selected Cypress Quad Data Rate II (QDRII) and QDRII+ SRAMs for use in its 28-nm Stratix(R) V GX FPGA Development Kit. Cypress's SRAMs enable the Stratix V FPGA Development Kit to deliver line rates up to 100 Gbps.
The Stratix V GX FPGA Development Kit provides a complete design environment to start developing Altera's high-performance 28-nm FPGAs for use in a broad range of applications such as networking line cards, advanced LTE basestations, high-end RF cards and military radar. The kit enables designers to develop and test Stratix V GX FPGAs with the latest protocols (PCIe Gen3) and memory subsystems, including DDR3, QDRII and QDRII+. The 4.5-MB of QDRII+ memory featured on the Stratix V GX FPGA development board interface with the FPGA through the device's hard memory controllers, delivering maximum performance and the lowest latency.
The QDRII+ devices feature On-Die Termination (ODT), which improves signal integrity, reduces system cost, and saves board space by eliminating external termination resistors. They include densities up to 144 Mbit and speeds up to 550 MHz. With an optional burst of 4, the 144-Mbit QDRII+ is capable of 550 million transactions per second, and employs 2.5-cycle latency. The Burst of 2 device delivers up to 666 million transactions per second, offering the highest performance memory interface available. The 65-nm SRAMs are ideal for networking applications, including core and edge routers, fixed and modular Ethernet switches, 3G basestations, and secure routers. They also enhance the performance of medical imaging and military signal-processing systems.
"Cypress's QDRII and QDRII+ provide the speed, density and low-latency that today's high-performance networking solutions require," said Bernhard Friebe, senior marketing manager for Altera's high-end products. "Supporting the latest memory technologies like QDRII and QDRII+ in our Stratix V FPGAs, we enable our customers to maximize the capabilities of their end system."
"The Stratix V FPGAs are bringing networking performance to a new level," said Sudhir Gopalswamy, senior director of Cypress's Synchronous SRAM Business Unit. "We're pleased to provide the memory technology that enables customers to get the full benefit of these advances."
