Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm RoHS compliance status and check for specific manufacturing date codes if long-term availability is required for production runs.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are sufficient for the design logic requirements. Ensure the 144-pin TQFP footprint matches the PCB layout constraints. Verify that the 6ns speed grade meets the timing closure requirements of the target application clock frequencies.

Complex Programmable Logic Devices Part Context

This component belongs to the CoolRunner-II family, designed for low-power, high-density CPLD applications. It serves as a successor to earlier Xilinx CPLD lines, offering improved density and reduced power consumption while maintaining compatibility with standard development tools like ISE Design Suite.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to proprietary architecture. Consider equivalent devices from Lattice Semiconductor (e.g., MACHXO2 series) or Microchip (MachXO3L series) after verifying logic capacity and I/O voltage compatibility.
