Advanced CoolRunner-II Architecture Features
DataGATE Technology
The XC2C256-7TQG144I incorporates DataGATE technology, which allows selective disabling of unused inputs during specific operational phases. This feature significantly reduces dynamic power consumption by minimizing unnecessary signal switching.
CoolCLOCK Technology
CoolCLOCK combines clock division with DualEDGE flip-flops to reduce clock network power consumption by up to 50%. This innovative approach maintains full performance while dramatically lowering power requirements.
Advanced Interconnect Matrix (AIM)
The device architecture consists of eight Function Blocks interconnected by a low-power Advanced Interconnect Matrix. The AIM feeds 40 true and complement inputs to each Function Block, enabling efficient signal routing with minimal power overhead.
Dual I/O Banking
Two independent I/O banks allow simultaneous interfacing with multiple voltage domains (3.3V, 2.5V, 1.8V, and 1.5V), simplifying mixed-voltage system designs.
