Architecture Overview of the Spartan-II FPGA Family
Configurable Logic Blocks (CLBs)
The C2S200-6FGG661C features a programmable and flexible architecture built around Configurable Logic Blocks. Each CLB contains four logic cells (LCs), with each logic cell consisting of a 4-input function generator (Look-Up Table), a storage element, and carry logic. The CLBs provide:
- Four direct feedthrough paths per CLB
- Function generators configurable as 4-input LUTs
- Dual-port distributed RAM capability
- 16-bit shift register mode for data capture applications
Input/Output Blocks (IOBs)
The IOB architecture supports multiple I/O signaling standards for seamless integration with various system components:
| I/O Standard |
Description |
