XC2S200-6FGG1257C Architecture Overview
H3: Configurable Logic Blocks (CLBs)
The heart of the XC2S200-6FGG1257C is its array of 1,176 Configurable Logic Blocks (CLBs). Each CLB contains Look-Up Tables (LUTs), flip-flops, and multiplexers, enabling flexible implementation of both combinational and sequential digital logic. The 28×42 CLB grid provides substantial capacity for complex algorithms and state machines.
H3: Input/Output Blocks (IOBs)
The device features 284 programmable I/O pins surrounding the CLB core. Each IOB supports:
- Programmable slew rate control
- Optional pull-up and pull-down resistors
- Input delay elements for timing margin
- Multiple I/O standards including LVTTL, LVCMOS, and PCI compatibility
H3: Block RAM
Two columns of block RAM are located on either side of the CLB array, providing 56K bits of dedicated high-speed memory. Block RAM is ideal for FIFOs, data buffers, look-up tables, and embedded storage requirements.
H3: Delay-Locked Loops (DLLs)
Four Delay-Locked Loops (DLLs) — positioned one at each corner of the die — provide clock management functions including:
- Clock deskewing
- Frequency multiplication and division
- Phase shifting
- Duty cycle correction
H3: Routing Architecture
The CLBs, IOBs, block RAM, and DLLs are interconnected via a hierarchical routing fabric, offering versatile signal routing with minimal propagation delay. This architecture supports both local (short) and global routing resources, which is critical for achieving the -6 speed grade’s 263 MHz clock performance.
Configuration Modes
The XC2S200-6FGG1257C supports multiple configuration modes, giving designers flexibility in how the device is programmed at startup.

Frequently Asked Questions (FAQ)
H4: What does the “-6” speed grade mean on the XC2S200-6FGG1257C?
The -6 speed grade is the fastest available in the Spartan-II family, supporting system clock speeds up to 263 MHz. It is only offered in the commercial temperature range (0°C to +85°C). Devices requiring industrial temperature support should use the -5 speed grade.
H4: Is the XC2S200-6FGG1257C still in production?
The Spartan-II family has reached end-of-life status. However, the XC2S200 remains widely available through authorized component distributors and excess inventory channels. Always purchase from reputable, authorized sources to avoid counterfeit components.
H4: What is the difference between FG and FGG packages?
The FGG package designation indicates a Pb-free (RoHS-compliant) version of the Fine-Pitch BGA. The standard FG package uses traditional tin-lead solder balls. Both are functionally and pin-to-pin compatible.
H4: Can the XC2S200-6FGG1257C be reprogrammed in the field?
Yes. All Spartan-II FPGAs are fully reprogrammable in-system. Configuration can be updated via Master Serial, Slave Serial, Slave Parallel, or JTAG boundary-scan modes without any hardware replacement.
H4: What tools do I need to program the XC2S200-6FGG1257C?
You will need Xilinx ISE Design Suite (version 14.7 is the final release), a compatible JTAG cable (such as the Xilinx Platform Cable USB), and the IMPACT programming utility included with ISE.
Summary
The XC2S200-6FGG1257C is the largest, fastest, and most capable device in the Xilinx Spartan-II FPGA family.
