What Is the XC2S200-6FGG1225C?

The XC2S200-6FGG1225C is a Field-Programmable Gate Array (FPGA) from Xilinx’s Spartan-II family — one of the most widely deployed programmable logic families in electronics history. This specific variant combines 200,000 system gates and 5,292 logic cells with the “-6” speed grade, the fastest commercially available speed grade for the Spartan-II series, housed in a high-density FGG1225 Ball Grid Array (BGA) package.

The “G” in the package code confirms Pb-free, RoHS-compliant construction, while the “C” suffix specifies a commercial operating temperature range of 0°C to +85°C. These two attributes together make the XC2S200-6FGG1225C a strong fit for modern production environments where both performance and environmental compliance are non-negotiable.

Built on a proven 0.18 µm CMOS process and operating from a 2.5V core supply, the XC2S200-6FGG1225C delivers high-speed digital logic capability across applications in communications, industrial automation, embedded systems, and signal processing.

Decoding the XC2S200-6FGG1225C Part Number

Every character in a Xilinx part number carries specific meaning. Understanding the ordering code helps you verify that you have selected the correct device for your design requirements.

Key distinction: The “GG” (double-G) in FGG1225 indicates a Pb-free package. A single “G” suffix (FG) indicates standard tin-lead solder. Always confirm the correct suffix when procuring for RoHS-regulated markets.

XC2S200-6FGG1225C Architecture Deep Dive

Configurable Logic Blocks (CLBs)

At the core of the XC2S200-6FGG1225C is a 28×42 array of 1,176 Configurable Logic Blocks. Each CLB consists of two logic cell slices, and each slice contains:

• Two 4-input Look-Up Tables (LUTs) for combinational logic
• Two storage elements (flip-flops or latches)
• Fast carry and arithmetic logic
• Wide-function multiplexers

This architecture supports efficient implementation of everything from simple glue logic to complex state machines and pipelined arithmetic units.

Distributed RAM

The LUT-based distributed RAM provides 75,264 bits of fast, flexible on-chip storage. It integrates directly into the CLB fabric and is ideal for FIFOs, shift registers, and small lookup tables embedded within your logic design.

Block RAM

The XC2S200-6FGG1225C includes two dedicated columns of block RAM totalling 57,344 bits (56K). Block RAM supports true dual-port access with independent read and write widths, enabling efficient data buffering and memory-intensive design patterns.

Delay-Locked Loops (DLLs)

Four Delay-Locked Loops, one in each corner of the die, provide advanced clock management:

• Zero clock-skew distribution across the device
• Clock phase shifting (0°, 90°, 180°, 270°)
• Clock frequency multiplication and division
• Elimination of clock-insertion delay

DLLs are essential for designs operating at the device’s maximum -6 speed grade performance level.

Input/Output Blocks (IOBs)

The XC2S200-6FGG1225C supports up to 284 user I/O pins, arranged around the perimeter of the die. Each IOB supports:

• Programmable slew rate control
• Optional pull-up, pull-down, or keeper circuits
• Input delay elements for setup-time management
• Multiple I/O standards (LVTTL, LVCMOS, PCI, GTL, SSTL, HSTL, CTT, AGP)

Power Supply Design for the XC2S200-6FGG1225C

PCB design recommendations:

• Place 100 nF decoupling capacitors on every VCCINT pin, as close to the package as possible
• Place 10 µF bulk capacitors on both VCCINT and VCCO planes
• Use separate power planes for VCCINT and VCCO to minimize noise coupling

Frequently Asked Questions About the XC2S200-6FGG1225C

What does the speed grade “-6” mean for the XC2S200-6FGG1225C?

The “-6” speed grade is the fastest available commercial speed grade for the Spartan-II family. It specifies the minimum propagation delay and maximum operating frequency of the device. Higher numbers in the Spartan-II speed grade system indicate faster devices. The -6 grade is only offered for commercial temperature range parts.

Is the XC2S200-6FGG1225C Pb-free and RoHS compliant?

Yes. The double-G “GG” in the FGG1225 package code confirms that this part uses a Pb-free (lead-free) ball grid array. It meets the requirements of the EU’s RoHS Directive and is appropriate for use in modern electronics manufacturing.

How many I/O pins does the XC2S200-6FGG1225C support?

The XC2S200 core supports up to 284 user I/O pins. The FGG1225 package provides sufficient ball count to expose the full user I/O capacity of this device. This is the maximum I/O count available in the Spartan-II family.

Can the XC2S200-6FGG1225C be reconfigured in the field?

Yes. Like all Spartan-II FPGAs, the XC2S200-6FGG1225C is SRAM-based and fully reconfigurable. A new bitstream can be loaded via JTAG or an external configuration PROM after the device is deployed in the field, with no hardware changes required.

What is the difference between XC2S200-6FGG1225C and XC2S200-6FGG456C?

Both devices share the same Spartan-II XC2S200 silicon core with identical logic resources, memory, and -6 speed grade. The key difference is the package: the FGG1225 provides more physical balls (1225 vs. 456), which typically offers better power distribution, improved thermal performance, and more routing flexibility on the PCB.

What software do I use to program the XC2S200-6FGG1225C?

Use the Xilinx ISE Design Suite for design implementation and the IMPACT tool for JTAG-based bitstream programming. The device does not support Vivado, which is intended for Series-7 and newer Xilinx devices.
