Key Features of the XC2S200-6FGG1178C

High Logic Density and Programmable Architecture

The XC2S200-6FGG1178C is built around an array of Configurable Logic Blocks (CLBs) arranged in a 28 × 42 grid, delivering 1,176 total CLBs. Each CLB contains look-up tables (LUTs), flip-flops, and multiplexers, giving designers the flexibility to implement virtually any digital logic function. For engineers searching for a capable Xilinx FPGA solution, the XC2S200-6FGG1178C provides the logic resources needed for sophisticated designs.

Embedded Memory Resources

Two types of on-chip memory are available to accelerate data-intensive workloads:

• Distributed RAM: 75,264 bits, embedded within the CLB fabric for fast, small-scale storage
• Block RAM: 56K bits (56,000 bits) of dedicated two-port synchronous block memory for buffers, FIFOs, and lookup tables

Clock Management with Delay-Locked Loops (DLLs)

Four Delay-Locked Loop (DLL) circuits — one at each corner of the die — provide precise clock distribution, deskewing, and frequency synthesis. This ensures timing reliability across high-speed parallel data paths operating up to 200+ MHz system performance.

High-Speed -6 Speed Grade

The -6 speed grade is the fastest available in the Spartan-II family and is exclusively offered in the commercial temperature range. It enables the XC2S200-6FGG1178C to meet the most demanding timing closure requirements in high-throughput digital systems.

XC2S200-6FGG1178C Architecture Overview

Configurable Logic Blocks (CLBs)

Each CLB in the XC2S200-6FGG1178C contains two slices, and each slice includes:

• Two 4-input Look-Up Tables (LUTs)
• Two storage elements (flip-flops or latches)
• Fast carry and arithmetic logic
• Wide-function multiplexers

This architecture allows each CLB to implement complex combinatorial and sequential logic functions efficiently, maximizing gate utilization in real-world designs.

Input/Output Blocks (IOBs)

The IOBs surrounding the core logic support a wide range of single-ended and differential I/O standards. Features include:

• Programmable input delay
• Output slew rate and drive strength control
• Optional input hysteresis for noise immunity
• Support for common bus standards (PCI, AGP, LVDS, SSTL, HSTL)

Block RAM Architecture

Block RAM in the XC2S200 is arranged in two columns on opposite sides of the die. Each block RAM module can be configured as:

• Single-port or dual-port RAM
• Widths of ×1, ×2, ×4, ×8, or ×16 bits
• Synchronous read and write operations for reliable timing

Delay-Locked Loop (DLL) Circuits

The four DLL circuits provide:

• Zero-propagation-delay clock distribution
• Clock edge alignment and deskewing
• 2× and 0.5× frequency synthesis
• Phase shifting for interface timing
