XC2S200-6FGG1121C Architecture Overview
Configurable Logic Blocks (CLBs)
The heart of the XC2S200-6FGG1121C is its array of 1,176 Configurable Logic Blocks (CLBs) arranged in a 28×42 grid. Each CLB contains four logic cells, and every logic cell includes:
- A 4-input Look-Up Table (LUT) for implementing any combinational logic function
- A dedicated D-type flip-flop for registered logic
- Fast carry and arithmetic logic for efficient adder and multiplier implementations
- Support for 16 bits of distributed SelectRAM per logic cell
Block RAM Architecture
The XC2S200-6FGG1121C provides 14 block RAM modules, each offering a true dual-port, synchronous 4,096-bit (4 Kbit) RAM. These on-chip memory resources are ideal for:
- FIFOs and data buffers
- Lookup tables and coefficient storage
- Small embedded memories for processor-based designs
- Dual-port communication between processing elements
Input/Output Blocks (IOBs)
The device features programmable I/O blocks supporting multiple industry-standard voltage levels, including LVTTL, LVCMOS, PCI, and GTL+ standards. Each IOB includes:
- Independently programmable input and output delays
- Optional input flip-flops and output flip-flops
- Slew rate control (fast/slow)
- Programmable pull-up and pull-down resistors
Delay-Locked Loops (DLLs)
Four Delay-Locked Loops — one at each corner of the die — provide:
- Zero clock skew distribution across the device
- Frequency synthesis and clock multiplication
- Clock phase shifting for advanced system-level timing
- Board-level clock deskewing when used in loopback configurations

Key Features of the XC2S200-6FGG1121C
✅ Superior ASIC Replacement
The Spartan-II FPGA eliminates the non-recurring engineering (NRE) costs of mask-programmed ASICs. There is no minimum order quantity, no re-spin cost, and no obsolescence risk. Design changes can be deployed in-field without hardware replacement — an impossible feat with traditional ASICs.
✅ Speed Grade -6: Maximum Commercial Performance
The -6 speed grade is the fastest commercially available speed grade in the Spartan-II lineup. It delivers pin-to-pin propagation delays as fast as a few nanoseconds and a maximum toggle frequency of up to 263 MHz, enabling high-throughput data processing applications.
✅ Hierarchical SelectRAM Memory
The XC2S200-6FGG1121C implements Xilinx’s SelectRAM hierarchical memory architecture, combining two levels of on-chip memory:
- Distributed RAM: 75,264 bits derived from LUTs, providing very fast, single-cycle access
- Block RAM: 57,344 bits in dedicated synchronous dual-port modules for high-bandwidth memory operations
✅ Robust I/O Flexibility
With 284 user I/O pins in the 1121-pin package, engineers have ample connectivity for complex bus interfaces, multi-channel signal processing, and board-level integration. Programmable I/O standards ensure compatibility with a wide range of peripheral devices.
✅ Four Delay-Locked Loops (DLLs)
The integrated DLLs eliminate board-level clock distribution challenges, reduce clock uncertainty, and enable frequency synthesis without external oscillators or PLLs.
✅ Full IEEE 1149.1 Boundary Scan (JTAG)
Complete JTAG support allows in-circuit testing, boundary scan chain integration, and in-system programming through standard test infrastructure.
