The Defense-Grade Spartan-6Q family provides a secure foundation for information assurance and anti-tamper designs that require low power and low cost for Aerospace and Defense applications. The Spartan-6Q family is the third generation of secure product offered for high-level cryptography and tamper proofing approved by government agencies. Built on a mature 45 nm low-power copper process technology that delivers the optimal balance of cost, power, and performance, the Spartan-6Q family offers a more efficient, dual-register 6-input look-up table (LUT) logic and a rich selection of built-in system-level blocks. These include 18 Kb (2 x 9 Kb) block RAMs, second generation DSP48A1 slices, SDRAM memory controllers, enhanced mixed-mode clock management blocks, SelectIO technology, power-optimized high-speed serial transceiver blocks, PCI Express compatible Endpoint blocks, advanced system-level power management modes, auto-detect configuration options, and enhanced IP security with AES and Device DNA protection. These features provide a low-cost programmable alternative to custom ASIC products with unprecedented ease of use. Spartan-6Q FPGAs offer the best possible solution for defense related applications where SWaP-C reduction is paramount with absolute security and ruggedized environment operation.
