XC2S200-6FGG1148C Key Specifications

The table below summarizes the core technical specifications of the XC2S200-6FGG1148C:

XC2S200-6FGG1148C Architecture Overview

## Configurable Logic Blocks (CLBs)

The XC2S200-6FGG1148C contains 1,176 CLBs arranged in a 28-column by 42-row matrix. Each CLB contains two slices, and each slice includes two 4-input Look-Up Tables (LUTs) and two flip-flops. The LUTs can also be configured as distributed RAM or shift registers, making the CLB array highly versatile for both logic and memory functions.

## Input/Output Blocks (IOBs)

The device supports up to 284 user I/O pins (excluding global clock pins). The IOBs support a wide range of programmable I/O standards, allowing engineers to interface with diverse external circuits without additional level-shifting components. Key IOB features include:

• Programmable drive strength and slew rate control
• Optional pull-up, pull-down, and keeper circuits
• Input delay elements for timing optimization
• Support for multiple single-ended and differential I/O standards

## Block RAM

Two columns of dedicated block RAM are distributed symmetrically on the die, providing 56K bits of fast on-chip storage. Each block RAM is dual-port, supports configurable data widths, and can be used independently or cascaded for larger memory arrays.

## Delay-Locked Loops (DLLs)

Four Delay-Locked Loops — one at each corner of the device — enable precise clock edge alignment, frequency multiplication and division, and phase shifting. The DLLs eliminate clock distribution delay, making the XC2S200-6FGG1148C well-suited for synchronous, high-frequency designs.

Configuration Modes

The XC2S200-6FGG1148C supports four configuration modes, as described in the table below:

Configuration data is loaded from an external PROM or microcontroller. The device enters a high-impedance state on all I/Os during and after configuration until explicitly released, providing safe initialization behavior.

Spartan-II Family Comparison: Where XC2S200 Stands

The XC2S200 is the largest and highest-density device in the Spartan-II family. The table below compares all family members:

As the table shows, the XC2S200 offers roughly 5.5× more logic cells and 12× more distributed RAM than the entry-level XC2S15, making it the right choice for complex, data-intensive designs within the Spartan-II family.

Speed Grade and Temperature: Understanding the “-6C” Suffix

### Speed Grade -6

The -6 speed grade is the fastest speed grade in the Spartan-II lineup and is exclusively available for the Commercial temperature range. A higher speed grade number indicates faster propagation delays and higher achievable clock frequencies — up to approximately 263 MHz system performance depending on design complexity.

### Commercial Temperature Range (C)

The “C” suffix designates the Commercial temperature range: 0°C to +85°C. This is appropriate for most indoor, controlled-environment applications such as:

• Consumer electronics
• Industrial control systems (indoor)
• Telecommunications line cards
• Networking and switching equipment
• Test and measurement instruments

For harsher environments, the Spartan-II family also offers an Industrial temperature range (-40°C to +100°C), though this is not available in the -6 speed grade.

FGG1148 Package: Fine Pitch BGA Details

### Package Characteristics

The FGG1148 is a 1148-ball Fine Pitch Ball Grid Array package. The “G” in “FGG” denotes that this is the Pb-free (lead-free, RoHS-compliant) version of the FG1148 package. Key package attributes:

### Why Choose the FGG1148 Package?

The large 1148-ball package was developed for the XC2S200 to expose the device’s full 284 user I/O capacity while providing adequate power and ground distribution across the ball grid. FBGA packages offer advantages over leaded packages including smaller PCB footprint per I/O, improved electrical performance, and better thermal characteristics in dense board designs.

Frequently Asked Questions (FAQ)

 Is the XC2S200-6FGG1148C RoHS compliant?

Yes. The “G” in the package code FGG1148 indicates a Pb-free, RoHS-compliant package. This makes the XC2S200-6FGG1148C suitable for designs targeting European Union RoHS regulations and other global lead-free mandates.

What is the maximum operating frequency of the XC2S200-6FGG1148C?

With the -6 speed grade, the XC2S200 supports system performance up to approximately 263 MHz, though the practical maximum frequency in a user design depends on logic depth, fan-out, and routing congestion.

 Can the XC2S200-6FGG1148C be used in industrial temperature applications?

No. The -6 speed grade is exclusively available in the Commercial temperature range (0°C to +85°C). For industrial temperature operation, engineers should select a -5 or -4 speed grade variant.

What configuration memory is compatible with the XC2S200-6FGG1148C?

The XC2S200 requires 1,335,840 configuration bits. It is commonly configured using Xilinx Platform Flash PROMs (e.g., XCF01S, XCF02S) in Master Serial mode or via a microcontroller using Slave Serial or Slave Parallel mode.

Is a direct pin-compatible replacement available?

Within the Spartan-II family, the XC2S200-5FGG1148C (speed grade -5) shares the same FGG1148 package and is a functional equivalent at lower speed. Engineers requiring higher performance or more I/O should evaluate the Spartan-IIE or later AMD/Xilinx FPGA families.
