XC2C128-7TQG144C Key Features and Benefits

Ultra-Low Power CoolRunner-II Architecture

The XC2C128-7TQG144C leverages Xilinx’s innovative CoolRunner-II architecture, specifically engineered for ultra-low power consumption. With standby current as low as 16 μA and standby power of just 28.8 μW, this CPLD dramatically extends battery life in portable applications while maintaining exceptional computational performance.

Advanced Power Management Technologies

DataGATE Technology

The XC2C128-7TQG144C incorporates DataGATE technology, a unique power-saving feature that allows designers to selectively disable unused inputs during specific operational phases. By blocking controlled switching signals, DataGATE prevents unnecessary power consumption from driving internal chip capacitances, enabling systems to approach near-zero power consumption when inputs are not actively required.

CoolCLOCK Technology

CoolCLOCK technology combines clock division (divide-by-2) with DualEDGE flip-flop triggering to significantly reduce dynamic power consumption. Since clock networks can be substantial power consumers in digital designs, CoolCLOCK drives the clock net at half frequency while doubling the effective clock rate using dual-edge triggering at the macrocells—cutting clock-related power consumption dramatically without sacrificing performance.

High-Speed Performance Capabilities

Despite its low power consumption, the XC2C128-7TQG144C delivers impressive performance metrics essential for demanding applications. The device achieves a maximum operating frequency of 152 MHz with pin-to-pin propagation delays as low as 7.5 nanoseconds, ensuring rapid signal processing and system responsiveness.

Flexible I/O Standards and Voltage Compatibility

The XC2C128-7TQG144C provides extensive I/O flexibility through support for multiple interface standards and voltage levels:

The device features two independent I/O banks, enabling simultaneous interfacing with multiple voltage domains (1.5V, 1.8V, 2.5V, and 3.3V) within a single design—simplifying system integration and reducing external level-shifting components.

CoolRunner-II CPLD Internal Architecture

Advanced Interconnect Matrix (AIM)

The XC2C128-7TQG144C utilizes Xilinx’s proprietary low-power Advanced Interconnect Matrix (AIM), which connects all function blocks with minimal power overhead. The AIM feeds 40 true and complement inputs to each function block, providing extensive routing resources while maintaining the device’s ultra-low power characteristics.

Function Block Organization

The CPLD contains 8 Function Blocks, each featuring:

The programmable logic array (PLA) architecture allows any product term to attach to any OR gate within the function block macrocells. Product terms can be reused up to 16 times within a single function block, maximizing logic density and design efficiency.

Macrocell Features

Each macrocell in the XC2C128-7TQG144C includes:

• Programmable D-type flip-flop with clock enable
• DualEDGE triggering capability
• Asynchronous set/reset options
• Configurable as registered or combinatorial output
• Individual output enable control
