Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '5' against the datasheet to confirm the 5 ns delay specification. Ensure the FTN256 package designation matches the required footprint dimensions and thermal characteristics for the target PCB layout.

Complex Programmable Logic Devices Selection Notes

Select this component when a balance of high speed (5 ns) and moderate density (512 macrocells) is required. Compare against the LC4512V-75 variant if lower speed requirements allow for potential cost optimization, or choose higher density families like LC5512MV if more macrocells are needed.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000V series, designed for applications needing non-volatile configuration and low power consumption. It serves as a successor to older GAL and EPM devices, offering reprogrammability while maintaining compatibility with standard CPLD design flows.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same speed grade may be limited. Consider the LC4512V-75FTN256I for slower applications or the LC5512MV series for increased macrocell count, though package and pinout differences must be evaluated.
