Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'A' against official Lattice documentation, as standard listings often cite 'LC4256V-75FTN256I'. Confirm that the 'A' designation does not imply a restricted or non-standard variant. Ensure the 256-pin FineLine BGA footprint matches the target PCB layout constraints. Check for RoHS compliance status in the latest datasheet revision.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require moderate logic density with high pin counts in a compact ball grid array form factor. Compare against the TQFP-176 variant if surface mount area is limited but height restrictions are less critical. Consider the 75 ns speed grade relative to system clock requirements. Evaluate power consumption characteristics against lower-density alternatives if energy efficiency is a primary constraint.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000V series, designed for cost-effective, low-power programmable logic solutions. The series offers a balance of performance and density, targeting applications where field programmability reduces time-to-market. The FTN256 package provides extensive I/O access while maintaining a relatively small footprint compared to larger BGA options.
