Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (5) against the required timing constraints for your design. Confirm that the TQFP-100 package is compatible with your PCB footprint and assembly process. Ensure the 1.8V core voltage requirement aligns with your power delivery network. Check for moisture sensitivity levels if the component has been stored for extended periods.

Complex Programmable Logic Devices Selection Notes

Select this part when 64 macrocells are sufficient for the logic density requirements. The 4.7 ns delay suits moderate-speed applications where 241 MHz operation is adequate. Choose the industrial temperature variant (-I) for environments exceeding commercial limits. Consider the 1.8V core voltage for low-power designs requiring multiple interface voltage options.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000ZE series, which offers enhanced features over the original 4000Z architecture. The series combines high speed with low power consumption, utilizing EEPROM technology for non-volatile configuration. It is designed for flexible CPLD applications requiring first-time-fit reliability and easy migration between device densities.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the ispMACH 4000ZE family with similar macrocell counts, such as the LC4064ZE-4TN100I or LC4064ZE-7TN100I, provided timing margins allow. Verify pinout compatibility before substitution. Cross-family replacements require careful review of I/O characteristics and power specifications.
