XC95288XL-10TQ144I

CPLDs, or Complex Programmable Logic Devices, are standalone semiconductor devices used in high-end embedded systems. One of the most popular CPLDs on the market is the XC95288XL-10TQ144I. This particular CPLD offers an expansive 10,000 logic gates in a single package, as well as up to 5,000 Virtual Input and Output (I/O) pins. It also offers enhanced triggering, variable clock speeds and clock-gating options.

The XC95288XL-10TQ144I is typically used for system-level applications such as motor control and digital signal processing. Designs utilizing this CPLD can use a wide range of logic functions, from simple combinatorial logic controllers to more sophisticated multicore microcontrollers. This makes the XC95288XL-10TQ144I especially attractive for applications that require fine tuning of logic and memory resources, such as embedded systems.

The XC95288XL-10TQ144I works on the principle of implementing an array of lookup tables (LUTs). A LUT is essentially a special circuit containing a set of predetermined values, which can be used as an intermediary for a particular type of logic operation. When a data input is applied to the LUT, the corresponding output value is taken from the lookup table. This enables the CPLD to effectively achieve the desired logic operation in several clock cycles, rather than waiting for the logic to propagate through several logic gates.

The XC95288XL-10TQ144I also offers advanced programming feature such as global interconnects and user-defined pins. Global interconnects allow for long distances of routing within the array, while user-defined pins give more control over the number of I/O pins that can be used. Furthermore, the CPLD utilizes a patented reconfigurable logic cell (RLC) technology that provides designers with a wide array of configurable logic functions that can be programmed in real-time.

Overall, the XC95288XL-10TQ144I is a powerful and versatile CPLD that is ideal for system-level applications such as motor control and embedded systems. It offers the advantage of having 10,000 logic gates in a single package, as well as up to 5,000 Virtual Input and Output (I/O) pins. In addition, it utilizes advanced programming features such as global interconnects and user-defined pins. Finally, the XC95288XL-10TQ144I works on the principle of implementing an array of lookup tables (LUTs), allowing for faster logic operations without waiting for propagation through several logic gates.
