XC2S200-6FGG490C Architecture and Design
Configurable Logic Block (CLB) Structure
The XC2S200-6FGG490C features an advanced CLB architecture organized in a 28 x 42 array, providing 1,176 total CLBs. Each CLB contains four logic cells (LCs) organized into two identical slices. Key CLB features include:
- 4-input Look-Up Tables (LUTs): Function generators implemented as LUTs support any Boolean function of four inputs
- Dedicated Carry Logic: Enables high-speed arithmetic operations and efficient multiplier implementations
- Storage Elements: Edge-triggered D-type flip-flops or level-sensitive latches with independent clock enable signals
- Cascade Chain: Supports wide-input function implementation
Input/Output Block (IOB) Capabilities
The XC2S200-6FGG490C IOBs provide versatile interfacing options supporting 16 high-performance I/O standards:
- LVTTL (2-24 mA drive strength)
- LVCMOS2
- PCI (3V/5V, 33 MHz/66 MHz compliant)
- GTL and GTL+
- HSTL Class I, III, and IV
- SSTL2 and SSTL3 Class I and II
- CTT
- AGP-2X
Each IOB includes three registers for input, output, and 3-state control, enabling efficient synchronous I/O operations.
