Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (0°C to 90°C). Confirm the 'FTN' designation corresponds to the 256-pin FineLine BGA package dimensions. Check manufacturer notices regarding RoHS compliance status, as older CPLD families may have specific environmental declarations. Ensure programming tools are compatible with the ispMACH 4000V architecture.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require more than 200 macrocells but less than FPGA complexity. Compare against the LC4384V series if lower power consumption is critical, noting potential differences in I/O drive strengths. Verify that the 256-pin BGA footprint fits the PCB layout constraints. Consider the 10 ns speed grade against system timing requirements to ensure adequate setup and hold margins.

Complex Programmable Logic Devices Part Context

This component is part of the Lattice ispMACH 4000V family, which succeeded earlier ispMACH 4000 devices. The 'B' variant typically denotes specific process improvements or pinout compatibility within the family. It serves as a drop-in replacement for legacy GALs and PALs in high-density applications, offering reprogrammability advantages over fixed logic gates while maintaining deterministic timing characteristics.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other parts from the LC4384 family with matching speed grades and package types. Cross-family migration to newer Lattice CPLDs requires verification of pin compatibility and I/O voltage level support.
