Electrical & Physical Characteristics

XC2S200-6FGG1251C Architecture Overview

Configurable Logic Blocks (CLBs)

The XC2S200 is built around a regular, flexible array of Configurable Logic Blocks (CLBs). Each CLB consists of two slices, and each slice contains two 4-input Look-Up Tables (LUTs), two storage elements (flip-flops or latches), and dedicated carry logic. With 1,176 CLBs in a 28×42 array, the XC2S200 provides substantial combinational and sequential logic capacity for complex design implementations.

Input/Output Blocks (IOBs)

Surrounding the CLB array is a perimeter of programmable Input/Output Blocks (IOBs). The XC2S200-6FGG1251C supports up to 284 user I/O pins, each configurable for multiple I/O standards including LVTTL, LVCMOS, PCI, GTL+, and HSTL. The IOBs also support input delays and optional registered inputs and outputs.

Delay-Locked Loops (DLLs)

The XC2S200 integrates four Delay-Locked Loops (DLLs), one positioned at each corner of the die. These DLLs enable zero-delay clock distribution, clock frequency synthesis, and phase shifting — critical features for high-speed synchronous designs.

Block RAM

Two columns of 56K bits total block RAM are placed on opposite sides of the die, between the CLB array and the IOB columns. This embedded memory provides fast, synchronous dual-port storage ideal for FIFOs, lookup tables, and data buffering.

Configuration Modes

The XC2S200-6FGG1251C supports multiple configuration modes, allowing flexible system integration:

During power-on and throughout configuration, all I/O drivers remain in a high-impedance state, ensuring safe system startup.

XC2S200-6FGG1251C vs. Other Spartan-II Devices

Understanding how the XC2S200-6FGG1251C compares to other members of the Spartan-II family helps engineers select the right device for their design requirements.

The XC2S200 is the largest and most capable device in the Spartan-II family, making it the preferred choice for designs requiring maximum logic density.

Applications of the XC2S200-6FGG1251C

The XC2S200-6FGG1251C is suitable for a wide range of industrial and commercial applications:

Embedded Systems & SoC Prototyping

The large logic capacity and abundant I/O resources make the XC2S200 ideal for prototyping system-on-chip designs before committing to an ASIC.

Telecommunications & Networking

The four DLLs and high-speed I/O capabilities support line-rate data processing, framing logic, and protocol bridging in telecom line cards and network equipment.

Industrial Automation & Control

The commercial-grade XC2S200-6FGG1251C supports real-time control logic, motor drive management, and sensor interface designs in factory automation environments.

Video & Image Processing

The combination of distributed RAM and block RAM resources enables pipelining of video frame data, making this FPGA useful for image acquisition and basic processing tasks.

Wireless & Consumer Electronics

The Spartan-II family was specifically designed for high-volume applications where a fast programmable solution adds benefits over fixed ASICs, including the ability to update the design in the field without hardware replacement.

Advantages of the -6 Speed Grade

The -6 speed grade is the fastest available for the Spartan-II family and is exclusively offered in the commercial temperature range. Key timing advantages include:

Why Choose Pb-Free (FGG) Packaging?

The “G” in FGG denotes a Pb-free (lead-free) package finish, making the XC2S200-6FGG1251C:

• RoHS compliant for sale and use in the European Union and other regulated markets
• Compatible with standard lead-free soldering processes (SAC alloys)
• Preferred by manufacturers adhering to environmental and sustainability standards
• Drop-in compatible with standard FGG1251 land patterns — no PCB redesign required
