Spartan-II FPGA Architecture Features
Configurable Logic Blocks (CLBs)
The XC2S200-6FGG542C incorporates 1,176 configurable logic blocks arranged in a 28 x 42 array. Each CLB contains multiple logic cells featuring four-input look-up tables (LUTs), flip-flops, and dedicated carry logic for arithmetic operations. This architecture enables efficient implementation of complex digital functions including counters, shift registers, and state machines.
Block RAM Memory Resources
This FPGA provides 56 Kbits of dedicated block RAM organized in multiple 4,096-bit memory blocks. Engineers can configure these memory resources as single-port RAM, dual-port RAM, or ROM to accommodate various data storage and buffering requirements in their designs.
Distributed RAM Capability
Beyond block RAM, the XC2S200-6FGG542C offers 75,264 bits of distributed RAM implemented within the CLB structure. This distributed memory architecture provides low-latency access for register files, FIFOs, and small lookup tables scattered throughout the design.
Clock Management and Delay-Locked Loops
