XC2S200-6FGG1227C Architecture & Internal Logic

Configurable Logic Blocks (CLBs)

The XC2S200-6FGG1227C features a 28×42 CLB array, yielding 1,176 total CLBs. Each CLB contains two slices, and each slice includes two 4-input Look-Up Tables (LUTs) plus two flip-flops. This architecture enables efficient implementation of both combinatorial and sequential digital logic.

Block RAM (BRAM)

The device integrates 56K bits of block RAM organized in two columns on opposite sides of the die. Block RAM supports both synchronous read/write and various depth-width configurations, making it well suited for FIFOs, lookup tables, and small embedded memory arrays.

Distributed RAM

In addition to block RAM, the XC2S200-6FGG1227C provides 75,264 bits of distributed RAM built directly into the CLB fabric. Distributed RAM is synthesized from the LUTs and is ideal for small, fast memory structures close to the logic that uses them.

Delay-Locked Loops (DLLs)

Four on-chip Delay-Locked Loops — placed at each corner of the die — provide precise clock management. DLLs eliminate clock distribution delay, support clock multiplication and division, and reduce clock skew across the device.

Input/Output Blocks (IOBs)

The XC2S200-6FGG1227C offers up to 284 user-configurable I/O pins (not including four global clock/user input pins). IOBs support a wide range of I/O standards including LVTTL, LVCMOS, PCI, and GTL+, providing flexible interfacing with external memory, processors, and peripherals.

Spartan-II Family Comparison Table

The XC2S200 is the largest device in the Spartan-II family. The table below shows how it compares against sibling devices:

The XC2S200-6FGG1227C’s 1,227-pin BGA package maximizes available I/O routing, making it ideal for designs requiring high pin counts.

---

Speed Grade -6: What It Means for Your Design

The -6 speed grade is the fastest commercially available grade in the Spartan-II family and is exclusively offered in the Commercial temperature range (0°C to +85°C). A higher (less negative) speed grade number means faster propagation delays and higher maximum clock frequencies. For timing-critical applications, the -6 grade provides the best performance margin within the Spartan-II platform.

FGG1227 Package: Fine-Pitch BGA Details

The FGG1227 package is a 1,227-ball Fine-Pitch Ball Grid Array. Key packaging attributes include:

The Pb-free FGG variant is identified by the double-G in the ordering code. Xilinx introduced Pb-free options across all Spartan-II device/package combinations to meet global RoHS environmental requirements.

XC2S200-6FGG1227C Applications & Use Cases

#### Industrial Automation

High I/O count and stable 2.5V logic make the XC2S200-6FGG1227C well suited for motor control interfaces, sensor fusion, and real-time logic processing in industrial environments.

#### Telecommunications & Networking

The device’s block RAM, DLLs, and fast speed grade make it effective for protocol bridging, framing, and signal processing in telecom line cards and network equipment.

#### Embedded Computing & Co-Processing

With 5,292 logic cells and 1,176 CLBs, the XC2S200-6FGG1227C can implement complete embedded processor peripherals or serve as a co-processor alongside CPUs in SoC-style board designs.

#### Test & Measurement Equipment

The reprogrammable nature of FPGAs allows test equipment designers to update logic in the field — a key advantage over mask-programmed ASICs for evolving test requirements.

#### Consumer Electronics Prototyping

The Spartan-II series was designed to be a cost-effective alternative to mask-programmed ASICs. The XC2S200-6FGG1227C shortens development cycles and allows field upgrades without hardware replacement.

Configuration & Design Tools

The XC2S200-6FGG1227C is configured via a serial or parallel bitstream loaded at power-up. Xilinx supports this device through the ISE Design Suite, which includes:

• XST – Synthesis tool for VHDL and Verilog designs
• PAR – Place-and-Route for timing closure
• iMPACT – Device programmer and bitstream download utility
• ChipScope Pro – On-chip logic analysis

Xilinx’s newer Vivado Design Suite does not support legacy Spartan-II devices. Designers working with the XC2S200-6FGG1227C should use ISE 14.7, the final release of the ISE toolchain.

Frequently Asked Questions (FAQ)

Q: Is the XC2S200-6FGG1227C still in production? The Spartan-II family is a mature (legacy) product line. While Xilinx (AMD) has issued product discontinuation notices for certain Spartan-II variants, surplus and aftermarket inventory remains available through authorized distributors. Always verify current stock and lifecycle status before designing this part into a new product.

Q: What is the difference between XC2S200-6FGG1227C and XC2S200-6FG1227C? The double-G (“FGG”) indicates the Pb-free, RoHS-compliant package. Single-G (“FG”) is the standard tin-lead package. Both are electrically identical; the difference is solely in the solder ball composition.

Q: Can I use Vivado to program the XC2S200-6FGG1227C? No. The XC2S200-6FGG1227C requires Xilinx ISE Design Suite (version 14.7). The Vivado toolchain does not support Spartan-II devices.

Q: What I/O standards does the XC2S200-6FGG1227C support? Supported I/O standards include LVTTL, LVCMOS2, PCI (3.3V), GTL, GTL+, HSTL (Class I & III), SSTL2 (Class I & II), and SSTL3 (Class I & II).

Q: What are common replacement or alternative parts? For new designs, consider migrating to the Xilinx Spartan-3 or Spartan-6 families for improved performance, lower power, and current toolchain support. The XC3S200 (Spartan-3) offers a compatible logic density upgrade path.
