What Is the XC2S200-6FGG1185C? Understanding the Part Number

Before diving into technical specifications, it helps to decode the part number:

The “G” in FGG denotes a Pb-free (RoHS-compliant) package, distinguishing it from the standard FG variant. The -6 speed grade is the highest available in the Spartan-II family and is exclusively offered in the commercial temperature range, making the XC2S200-6FGG1185C ideal for fast, high-density designs in benign thermal environments.

XC2S200-6FGG1185C Architecture and Internal Logic Resources

Configurable Logic Blocks (CLBs)

The XC2S200-6FGG1185C features a 28×42 CLB array, totaling 1,176 CLBs. Each CLB contains:

• Four logic cells, each with a 4-input Look-Up Table (LUT) and a D-type flip-flop
• Carry logic for fast arithmetic operations
• Wide function multiplexers for implementing complex boolean expressions
• Cascade chains for efficient multi-bit logic

This architecture enables efficient implementation of state machines, DSP functions, and custom logic pipelines directly on-chip.

Block RAM Resources

The device includes 56K bits of dedicated block RAM, organized in dual-port memory arrays. These memory blocks are ideal for:

• FIFO buffers in data-streaming pipelines
• Coefficient storage for DSP filters
• Lookup tables and ROMs
• Embedded processor instruction/data memory

Additionally, 75,264 bits of distributed RAM are available using the LUT fabric, enabling fine-grained memory placement throughout the design.

Delay-Locked Loops (DLLs)

The XC2S200-6FGG1185C includes four Delay-Locked Loops (DLLs), one at each corner of the die. DLLs are used for:

• Clock edge alignment and phase shifting
• Frequency synthesis (multiplication/division)
• Zero-delay clock buffering to eliminate clock skew across the device

Input/Output Blocks (IOBs)

With up to 284 user I/O pins in this package, the XC2S200-6FGG1185C supports a wide range of I/O standards:

Each IOB includes programmable input delay, optional flip-flops for registered I/O, and pull-up/pull-down resistors, enabling seamless interfacing with diverse external logic families.

Why Choose the XC2S200-6FGG1185C? Key Advantages

#### Superior Cost-to-Performance Ratio vs. ASICs

The Spartan-II family was designed as a cost-effective alternative to mask-programmed ASICs. The XC2S200-6FGG1185C eliminates the high NRE (Non-Recurring Engineering) costs, long development cycles, and fixed silicon risks of traditional ASICs. Designers can reprogram the device in the field — no hardware replacement needed.

#### Fastest Available Speed Grade in Spartan-II

The -6 speed grade is the fastest offering in the Spartan-II series, enabling operation at up to 263 MHz. This makes the XC2S200-6FGG1185C the right choice for time-critical signal processing and high-bandwidth data interfaces.

#### High I/O Count for Complex Board Designs

The FGG1185 package provides the highest pin count in the Spartan-II portfolio. With 284 usable user I/Os, engineers can interface with multiple buses, memory chips, sensors, and peripherals simultaneously — reducing the need for external logic expanders or bus bridges.

#### Pb-Free, RoHS-Compliant Packaging

The “G” in FGG indicates the device uses a lead-free solder ball array, meeting RoHS (Restriction of Hazardous Substances) compliance requirements for commercial and industrial products sold in the EU, UK, and other regulated markets.

XC2S200-6FGG1185C Applications

The XC2S200-6FGG1185C is well suited for a broad spectrum of industries and use cases:

---

Programming and Configuration

The XC2S200-6FGG1185C uses SRAM-based configuration, meaning it must be loaded with a bitstream at power-up. Configuration modes supported include:

• Master Serial – Driven by an external PROM (e.g., Xilinx XCF series)
• Slave Serial – Controlled by an external processor or CPLD
• Slave Parallel (SelectMAP) – Fast byte-wide configuration for quick startup
• JTAG (Boundary Scan) – IEEE 1149.1-compliant, supports in-system programming and debug

For production systems, pairing the XC2S200-6FGG1185C with a Xilinx Platform Flash PROM provides a compact and reliable configuration solution.

Design Tools and Software Support

The XC2S200-6FGG1185C is supported by Xilinx (AMD) design toolchains:

For engineers starting new designs, note that the Spartan-II family is classified as mature/legacy by AMD Xilinx. For new development, AMD recommends migrating to Spartan-7 or Artix-7 families. However, the XC2S200-6FGG1185C remains widely used in legacy system maintenance, field repairs, and long-lifecycle industrial equipment.

Ordering Information and Part Number Variants

The XC2S200 is available in multiple package and speed grade combinations. The table below lists key commercial variants:

Note: The -6 speed grade is exclusively available in the commercial temperature range (0°C to +85°C). For industrial temperature range (-40°C to +100°C) requirements, the -5 speed grade must be used.

Frequently Asked Questions (FAQ)

Q: What is the difference between XC2S200-6FGG1185C and XC2S200-6FG1185C? The “G” in FGG designates a Pb-free (RoHS-compliant) package. The FGG1185 and FG1185 are physically identical in pinout; the difference is the solder ball material used in the BGA package.

Q: Is the XC2S200-6FGG1185C still in production? The Spartan-II family is classified as a legacy/mature product by AMD Xilinx. While it may not be in active production, it remains available through authorized distributors and component brokers for replacement and maintenance applications.

Q: What FPGA should I use for a new design replacing the XC2S200? For new designs, AMD Xilinx recommends the Spartan-7 (XC7S series) or Artix-7 (XC7A series) families, which offer significantly higher logic density, lower power consumption, and modern high-speed serial I/O.

Q: Can the XC2S200-6FGG1185C be used for high-speed serial interfaces? The Spartan-II family does not include dedicated high-speed serial transceivers (SERDES). For designs requiring GbE, PCIe, or SATA, a device with integrated MGT (Multi-Gigabit Transceivers) such as a Spartan-6 or Artix-7 is recommended.
