XC2S200-6FGG1128C Architecture & Internal Features

Configurable Logic Blocks (CLBs)

The heart of the XC2S200 architecture is its array of 1,176 Configurable Logic Blocks, arranged in a 28-column by 42-row matrix. Each CLB contains four logic cells, and each logic cell includes a four-input Look-Up Table (LUT), a storage element (flip-flop), and carry logic. This architecture supports:

• Combinational and registered logic implementation
• Efficient arithmetic functions using dedicated carry chains
• Fast shift-register and distributed RAM inference

Input/Output Blocks (IOBs)

The XC2S200-6FGG1128C offers up to 284 user-configurable I/O pins (excluding the four dedicated global clock inputs). Each IOB supports multiple I/O standards, including LVTTL, LVCMOS, PCI, and SSTL, providing maximum interface flexibility with external components, buses, and peripherals.

Block RAM

Two columns of dedicated Block RAM are embedded within the device, totalling 56 Kbits of dual-port synchronous SRAM. Block RAM is ideal for implementing FIFOs, large lookup tables, data buffers, and on-chip memory without consuming CLB resources.

Delay-Locked Loops (DLLs)

Four Delay-Locked Loops are placed at the corners of the die. DLLs enable:

• Zero-delay clock buffering and distribution
• Clock frequency synthesis and multiplication
• Clock phase shifting for timing optimization

Routing Architecture

A hierarchical routing network connects all functional blocks with minimal delay. The Spartan-II routing includes local, long-line, and global routing resources, ensuring timing closure is achievable even in complex, high-fanout designs.
