XC2C128-6TQ144C

## Overview

The Xilinx XC2C128-6TQ144C is a member of the CoolRunner-II CPLD family, optimized for low-power, high-speed, and predictable timing applications. Fabricated using a 0.13 μm CMOS process, this CPLD combines low static power consumption with fast propagation delays, making it ideal for glue logic, control path implementation, bus interfacing, and small-scale digital logic designs. The device is industrial-grade, suitable for operation over a wide temperature range, and provides deterministic performance with minimal dynamic power requirements.

## Device Architecture

* Logic Blocks: The device features 128 macrocells organized into four function blocks. Each function block contains multiple macrocells that combine combinational logic and flip-flop storage elements.
* Macrocells: Each macrocell supports AND-OR logic, flip-flops with synchronous or asynchronous set/reset, and optional clock enable functionality. Macrocells provide flexible implementation of combinational and sequential logic with predictable timing.
* Interconnect: Dedicated interconnect resources provide fast, deterministic routing between logic blocks, I/O pins, and macrocells. Signal propagation is optimized to minimize skew and ensure synchronous operation across the device.
* Registers and Flip-Flops: Each macrocell contains one D-type flip-flop, supporting synchronous clocking and optional asynchronous set/reset.
