General Description
The Spartan-6 family provides leading system integration capabilities with the lowest total cost for high-volume applications. The
thirteen-member family delivers expanded densities ranging from 3,840 to 147,443 logic cells, with half the power consumption of previous
Spartan families, and faster, more comprehensive connectivity. Built on a mature 45 nm low-power copper process technology that
delivers the optimal balance of cost, power, and performance, the Spartan-6 family offers a new, 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-6 FPGAs offer the best solution for
high-volume logic designs, consumer-oriented DSP designs, and cost-sensitive embedded applications. Spartan-6 FPGAs are the
programmable silicon foundation for Targeted Design Platforms that deliver integrated software and hardware components that enable
designers to focus on innovation as soon as their development cycle begins.
