Stratix III FPGAs

With a Stratix® III FPGA, you get the world's highest performance and highest density 65 nm FPGA combined with the lowest possible power consumption. A Stratix III FPGA will provide the high-performance and high-integration capabilities needed for next-generation basestations, network infrastructure, and advanced imaging equipment. What's more, the performance, utilization and compilation advantages of a Stratix III FPGA actually increase with design size:

With Intel's innovative custom logic solutions, you get the devices you want with the features you want when you want them. You also get the collaboration and support you need to design your next-generation systems with confidence.

Building on the Stratix II Architecture

Lowest Power High-End 65 nm FPGA

To design the Stratix III FPGA, product planners began with the Stratix II FPGA architecture. Then, in collaboration with the top technologists from over 50 of Intel's major customers, they defined, designed, and developed the most advanced FPGA architecture for next-generation systems.

As a result, the Stratix III 65 nm FPGA incorporates features to combine high performance with the lowest possible static and dynamic power consumption—up to 50 percent lower than previous generation high-end FPGAs, including:

The Stratix III FPGA family is engineered for high-speed core performance, coupled with high-speed I/O and the best signal integrity in the industry. For example, they are the only 65 nm FPGA family capable of implementing DDR3 at 533 MHz and to offer LVDS performance up to 1.6 Gbps. This increase in performance is achieved by the implementation of:

Best Price/Performance Options

To give you the best price/performance solution for your design applications, the Stratix III FPGA family offers two application-optimized variants:

  • Stratix III L devices focus on logic-rich applications
  • Stratix III E devices focus on DSP-rich and memory-rich applications

There are also migration paths between all members of the Stratix III FPGA family and the Stratix IV E FPGA. See the Migrate Your Stratix III FPGA Designs Up to a Stratix IV E FPGA Without Changing Pin-Outs page for details.

Advanced Process Technology

Intel and long-standing fabrication partner the Taiwan Semiconductor Manufacturing Company, Ltd. (TSMC), have been working on 65 nm process technologies since 2003. Since then, Intel has developed multiple test chips as part of a rigorous program to ensure that Stratix III FPGAs are on the latest 65 nm technology, and continue to be successfully delivered in volume and on schedule.
