Advanced Clock Management Features
The XC2C256-7VQ100I includes sophisticated clock management capabilities that enhance both performance and power efficiency.
DualEDGE Flip-Flop Technology
The DualEDGE flip-flop feature allows high-performance synchronous operation using lower frequency clocking. By triggering on both rising and falling clock edges, designers can reduce clock frequencies while maintaining data throughput, resulting in significant power savings.
Clock Divider Circuit
The integrated clock divider can divide an externally supplied global clock (GCK2) by eight different values, providing both even and odd frequency divisions. When combined with the DualEDGE flip-flop, this enables the CoolCLOCK feature for optimized power consumption.
DataGATE Power Management
DataGATE technology allows designers to selectively disable inputs during idle periods, dramatically reducing power consumption by eliminating unnecessary signal switching.
