XC2S200-6FGG1115C Architecture and Core Features

Configurable Logic Blocks (CLBs) – The Heart of the FPGA

The XC2S200 contains 1,176 Configurable Logic Blocks arranged in a 28 × 42 array. Each CLB provides flexible look-up tables (LUTs), flip-flops, and carry logic, enabling efficient implementation of combinatorial and sequential logic. The distributed RAM totals 75,264 bits, ideal for small buffers and shift registers embedded directly in the logic fabric.

Block RAM – On-Chip Memory for High-Speed Data Buffering

The XC2S200-6FGG1115C includes 14 blocks of 4,096-bit dual-port synchronous RAM, yielding a total of 56 Kbits of on-chip block RAM. Each memory block supports:

• Fully synchronous dual-port operation
• Independent control signals per port
• Configurable data widths for each port independently
• Single-cycle read and write access

This makes the device well-suited for FIFO buffers, data pipelines, and look-up table storage without consuming CLB resources.

Delay-Locked Loops (DLLs) – Precision Clock Management

Four on-chip Delay-Locked Loops, one at each corner of the die, provide:

• Zero-skew clock distribution
• Clock frequency synthesis and multiplication
• Phase shifting for timing closure
• Board-level clock deskew when driving clocks off-chip and back on

Input/Output Blocks (IOBs) – Flexible I/O Interface

The XC2S200-6FGG1115C supports up to 284 user I/O pins (excluding 4 dedicated global clock pins). The IOBs support multiple industry-standard interface standards and include programmable pull-up and pull-down resistors, slew-rate control, and output drive strength configuration.
