Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'TN44I' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the required programming tools support the ispMACH 4000V architecture for successful configuration. Check for any recent product change notices regarding package markings or material composition updates.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity. The 7.5 ns speed grade offers a balance between performance and power consumption. Consider the TQFP-44 package constraints for PCB layout. Compare against the LC4064C variant if lower power consumption is prioritized over higher speed capabilities.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000V series, which succeeded earlier generations like the ispMACH 4000. The 'V' designation indicates the specific process generation offering improved performance characteristics compared to previous versions. It serves as a drop-in replacement for legacy CPLDs requiring similar density and I/O counts.

Complex Programmable Logic Devices Replacement Considerations

The LC4064V-75T44I is listed as obsolete, with the LC4064V-75TN44I identified as a direct available substitute. Verify pin-to-pin compatibility before transitioning designs from older leaded packages to the current tin-nickel-gold plated variants.
