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 lookup 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, poweroptimized 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 lowcost 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.

Spartan-6 FPGA 器件列表:



Spartan-6 FPGAs store the customized configuration data in SRAM-type internal latches. The number of configuration bits is between 2.6 Mb and 33 Mb depending on device size but independent of the specific user-design implementation, unless compression mode is used. The configuration storage is volatile and must be reloaded whenever the FPGA is powered up.

This storage can also be reloaded at any time by pulling the PROGRAM_B pin Low. Several methods and data formats for loading configuration are available.

Bit-serial configurations can be either master serial mode, where the FPGA generates the configuration clock (CCLK) signal, or slave serial mode, where the external configuration data source also clocks the FPGA. For byte-wide configurations, master SelectMAP mode generates the CCLK signal while slave SelectMAP mode receives the CCLK signal for the 8- and 16-bit-wide transfer. In master serial mode, the beginning of the bitstream can optionally switch the clocking source to an external clock, which can be faster or more precise than the internal clock. The available JTAG pins use boundary-scan protocols to load bit-serial configuration data.
