XC2S200-6FGG1068C Architecture Overview

Configurable Logic Blocks (CLBs)

The Spartan-II CLB is the fundamental building block of the XC2S200-6FGG1068C. Each CLB contains two slices, and each slice consists of two 4-input Look-Up Tables (LUTs), dedicated carry logic, and two flip-flops. This architecture enables efficient implementation of both combinatorial and sequential logic, arithmetic functions, and distributed RAM configurations.

Input/Output Blocks (IOBs)

The XC2S200-6FGG1068C features programmable IOBs that support a wide range of single-ended and differential I/O standards. Each IOB includes input and output registers, programmable pull-up and pull-down resistors, and slew-rate control. The device supports LVTTL, LVCMOS33, LVCMOS25, LVCMOS18, and other common standards.

Block RAM

Two vertical columns of block RAM are positioned on opposite sides of the CLB array. Each block RAM tile is a true dual-port memory with configurable data widths. The XC2S200 provides a total of 56K bits of dedicated block RAM — ideal for FIFOs, frame buffers, and on-chip data storage.

Delay-Locked Loops (DLLs)

Four DLLs — one placed at each corner of the die — provide precise clock management. The DLLs allow for clock phase shifting, frequency synthesis (multiply and divide), and duty-cycle correction. This makes the XC2S200-6FGG1068C well-suited for synchronous design across multiple clock domains.

Configuration Modes

The XC2S200-6FGG1068C supports several standard Xilinx configuration modes, selected via the M[0:2] mode pins:

The device powers up with all I/O drivers in a high-impedance state and remains there throughout the configuration process, protecting connected circuitry from spurious signals.

Why Choose the XC2S200-6FGG1068C?

Highest Performance in the Spartan-II Family

The -6 speed grade designation means this is the fastest variant available for the XC2S200 silicon. Designers who need tight timing margins and minimal propagation delays should specify this speed grade.

Maximum Logic and I/O Density

With 5,292 logic cells and 284 user I/O pins, the XC2S200-6FGG1068C provides the highest capacity in the entire Spartan-II lineup. This is the go-to device when design complexity has outgrown smaller family members.

Pb-Free Package

The “G” suffix in “FGG” indicates a Pb-free (lead-free) FBGA package, ensuring compliance with RoHS and environmental regulations required in modern electronics manufacturing.

Cost-Effective Alternative to ASICs

The Spartan-II family was engineered to bridge the gap between simple CPLDs and expensive custom silicon. The XC2S200-6FGG1068C provides ASIC-like logic density at a fraction of the non-recurring engineering (NRE) cost, with the added advantage of full reprogrammability.

Frequently Asked Questions About the XC2S200-6FGG1068C

What does the “-6” speed grade mean on the XC2S200-6FGG1068C?

The -6 designation indicates the fastest speed grade within the Spartan-II XC2S200 device. A higher number means faster internal propagation delays and the ability to support higher clock frequencies. It is only available in the commercial temperature range.

Is the XC2S200-6FGG1068C still in production?

The Spartan-II family reached end-of-life status per Xilinx’s product discontinuation notices. Availability is typically through authorized distributors and excess inventory channels. Always verify stock and date codes when sourcing.

What software is used to program the XC2S200-6FGG1068C?

The XC2S200-6FGG1068C is supported by Xilinx ISE Design Suite. Note that the newer Vivado tool does not support the Spartan-II family. ISE is still available through AMD Xilinx’s legacy software portal.

How many I/O pins does the XC2S200-6FGG1068C have?

The device supports up to 284 user-configurable I/O pins. This count does not include the four dedicated global clock/user input pins.

What configuration interface does the XC2S200-6FGG1068C support?

The device supports Master Serial, Slave Serial, Slave Parallel, and JTAG (Boundary-Scan) configuration modes. It can be configured from an external PROM, a microprocessor, or a JTAG cable.
