The Spartan 6 series is a kind of low-cost and high-capacity FPGA. It adopts 45nm low-power copper-clad technology, which can balance power consumption, performance, and cost. The Spartan 6 series uses dual-register, 6-input LUTs, and one Series of built-in system-level modules, these system-level modules include 18Kb Block Ram, second-generation DSP48A21 Slice, SDRAM memory interface (DDR interface), robust hybrid clock management module, Select IO technology, and optimized high-speed serial transceiver GTP Transceiver, PCIe interface, advanced system-level power management mode, automatic configuration detection, enhanced IP with AES and Device DNA protection. Spartan 6 is particularly suitable for high-capacity logic design, user-oriented DSP design, and low-cost design.
