XC2S200-6FGG1256C Architecture Overview

Configurable Logic Blocks (CLBs)

The XC2S200-6FGG1256C is organized around a 28 × 42 array of Configurable Logic Blocks (CLBs), providing a total of 1,176 CLBs. Each CLB contains look-up tables (LUTs), flip-flops, and multiplexers that allow engineers to implement virtually any combinational or sequential logic function. The CLB architecture supports both synchronous and asynchronous designs with high efficiency.

Block RAM and Distributed Memory

Block RAM

The device includes 56K bits of dedicated block RAM, arranged in two columns on opposite sides of the die. Block RAM can be configured as single-port or dual-port memory, making it ideal for FIFOs, data buffers, and lookup tables requiring fast, predictable access times.

Distributed RAM

An additional 75,264 bits of distributed RAM is embedded within the CLB fabric, offering fine-grained, high-speed storage directly integrated into the logic structure. This is particularly useful for small, latency-sensitive data structures.

Delay-Locked Loops (DLLs)

Four Delay-Locked Loops (DLLs) are placed at each corner of the die, providing precise clock management capabilities including:

• Clock edge alignment
• Clock frequency synthesis (multiply/divide)
• Phase shifting
• Duty-cycle correction

This makes the XC2S200-6FGG1256C highly capable for designs requiring multiple clock domains or high-precision timing.

Input/Output Blocks (IOBs)

The device supports up to 284 user-configurable I/O pins, each with:

• Programmable drive strength
• Slew rate control
• Optional pull-up/pull-down resistors
• 3-state output control
• Support for multiple I/O standards

The 1256-ball package provides additional PCB routing flexibility, making this variant particularly well-suited for designs with demanding interconnect requirements.

Configuration Modes

The XC2S200-6FGG1256C supports multiple configuration methods to accommodate various system architectures:

During power-on and throughout configuration, all I/O drivers remain in a high-impedance state. After configuration, unused I/Os also remain high-impedance unless explicitly assigned.

Why Choose the XC2S200-6FGG1256C?

#### Speed Grade -6: Maximum Performance

The -6 speed grade is the fastest available in the Spartan-II family and is exclusively offered in the Commercial temperature range. With internal clock speeds reaching up to 263 MHz, this device handles demanding real-time processing tasks with ease.

#### Large 1256-Pin Package for I/O-Rich Designs

The FGG1256 package provides exceptional routing freedom on the PCB. For designs requiring a high number of external connections — such as memory interfaces, multi-bus systems, or high-channel-count data acquisition — the 1256-ball BGA offers more physical flexibility than smaller package variants.

#### Pb-Free (RoHS-Compliant) Construction

The “G” suffix in the part number (FGG) confirms the device is packaged in a lead-free, RoHS-compliant format. This is essential for products destined for markets governed by environmental regulations such as the EU RoHS Directive.

#### Cost-Effective Alternative to Custom ASICs

The Spartan-II family, including the XC2S200-6FGG1256C, was engineered as a high-value alternative to mask-programmed ASICs. It eliminates the high NRE (Non-Recurring Engineering) costs of ASICs while enabling field upgrades through reprogrammability — an advantage ASICs simply cannot offer.

#### Proven and Mature Technology

Built on a stable, well-documented 0.18 µm process, the XC2S200-6FGG1256C benefits from decades of deployment data, extensive community support, and mature toolchain support via Xilinx ISE Design Suite.
