Complex Programmable Logic Devices Procurement Notes

Verify that the specific part number suffix corresponds to the required automotive grade certification, as standard commercial variants lack AEC-Q100 compliance. Confirm package marking and date codes align with current production lot requirements. Ensure design files account for the specific moisture sensitivity level associated with the TQFP-100 housing during assembly processes.

Complex Programmable Logic Devices Selection Notes

Select this component when automotive reliability is mandatory alongside moderate logic density. Compare against the LC4128ZC series if lower power consumption is prioritized over the specific voltage characteristics of the V-series. Ensure the target application fits within the 128 macrocell limit and utilizes the available 64 I/O resources efficiently without exceeding the thermal dissipation limits of the chosen enclosure.

Complex Programmable Logic Devices Part Context

This device belongs to Lattice's ispMACH 4000V family, designed specifically for high-performance applications requiring non-volatile configuration. The V-series distinguishes itself through optimized speed grades and robust I/O capabilities suitable for demanding environments. It serves as a direct evolution of earlier CPLD generations, offering improved timing performance while maintaining backward compatibility with existing design tools and methodologies.

Complex Programmable Logic Devices Replacement Considerations

The XC95108-15PC84C is identified as a discontinued alternative, with the LC4128V-75TN100C listed as a similar replacement option. Designers should verify pinout compatibility and electrical parameter alignment when substituting these parts, particularly regarding operating voltage ranges and package dimensions.
