XC2S200-6FGG1165C Architecture and Logic Resources

Configurable Logic Blocks (CLBs)

The XC2S200-6FGG1165C is organized around a 28 × 42 array of Configurable Logic Blocks (CLBs), totaling 1,176 CLBs. Each CLB contains four logic cells, and each logic cell includes:

• A 4-input Look-Up Table (LUT) for implementing any combinatorial function
• A D-type flip-flop for registering outputs
• Fast carry logic for efficient arithmetic operations
• Dedicated multiplexers for flexible routing

This architecture supports the implementation of complex state machines, arithmetic units, and custom digital signal processing pipelines — all within a single reprogrammable device.

Block RAM and Distributed RAM

Memory is a critical resource in FPGA design, and the XC2S200-6FGG1165C delivers on both fronts:

Block RAM supports true dual-port access, allowing simultaneous reads and writes from two independent clock domains — essential for FIFO buffers, lookup tables, and frame buffers in video and communications applications.

Digital Clock Management (DCM)

The XC2S200-6FGG1165C incorporates dedicated Digital Clock Management (DCM) resources that provide:

• Clock multiplication and division
• Phase shifting (fine-grained, 0° to 360°)
• Clock deskewing to minimize distribution delay
• Duty-cycle correction

These DCM features are critical for synchronous designs that demand precise timing control across multiple clock domains.

I/O Capabilities of the XC2S200-6FGG1165C

Supported I/O Standards

One of the defining strengths of the XC2S200-6FGG1165C is its support for 16 selectable I/O standards, which allows it to interface natively with a wide range of external components and buses:

This flexibility makes the XC2S200-6FGG1165C suitable for mixed-voltage board environments and modern high-speed communication protocols.

FGG1165 Package — Maximum I/O Density

The 1165-pin Fine-pitch BGA package is the highest pin-count option available for the XC2S200 device. This package is specifically chosen when designs require the maximum number of user I/O connections. Key package details include:

---

Configuration Modes of the XC2S200-6FGG1165C

The XC2S200-6FGG1165C supports four standard Spartan-II configuration modes, giving designers flexibility in how the device is programmed at power-up:

The JTAG/Boundary-Scan mode is especially useful for in-system programming and board-level testing, supporting IEEE 1149.1 compliance for full scan chain integration.

---

Speed Grade -6: What It Means for Your Design

The -6 speed grade is the fastest available within the Spartan-II family. A higher numerical speed grade indicates better (faster) timing performance. For the XC2S200-6FGG1165C, this translates to:

Choosing the -6 speed grade ensures that setup and hold time margins are maximized, making this part the preferred choice for clock-intensive and high-throughput data path designs.

Frequently Asked Questions (FAQ)

Q: What is the difference between XC2S200-6FGG456C and XC2S200-6FGG1165C? Both devices contain the same XC2S200 die, the same 284 user I/O pins, and the same logic resources. The primary difference is the physical package size. The FGG1165 uses a larger 1165-ball BGA footprint, which provides a less dense ball pitch — making PCB via escape routing easier on designs with tight layout constraints.

Q: Is the XC2S200-6FGG1165C RoHS compliant? Yes. The “G” character in the package code (FGG) indicates a Pb-free, RoHS-compliant package with lead-free solder balls.

Q: Can I use Vivado to program the XC2S200-6FGG1165C? No. The Spartan-II family is supported only by Xilinx ISE Design Suite 14.7. Vivado does not include support for this legacy device family.

Q: What configuration file format does the XC2S200-6FGG1165C use? The device uses a .bit bitstream file generated by ISE. The bitstream is loaded via one of the four supported configuration modes (Master Serial, Slave Serial, SelectMAP, or JTAG).

Q: What is the core supply voltage for the XC2S200-6FGG1165C? The internal logic core (VCCINT) operates at 2.5V. The I/O banks (VCCO) accept voltages from 1.5V to 3.3V depending on the I/O standard selected.
