CoolRunner-II CPLD Architecture Overview
The XC2C256-7TQG144C utilizes Xilinx’s proprietary CoolRunner-II architecture, which combines the benefits of traditional CPLD structures with advanced power-saving features.
Fast Zero Power Technology
Unlike conventional sense-amplifier-based CPLDs, the CoolRunner-II family uses cascaded CMOS gates to implement sum-of-products logic. This approach eliminates static current paths, achieving near-zero standby power while maintaining high-speed operation.
DataGATE Function
The DataGATE feature provides input signal blocking capability, allowing designers to halt unnecessary signal switching during idle periods. This unique power management option reduces dynamic current consumption without requiring external components.
In-System Programmability
The XC2C256-7TQG144C supports IEEE 1149.1 JTAG boundary scan for in-system programming and testing. This enables field updates and rapid prototyping without removing the device from the circuit board.
