Complex Programmable Logic Devices Procurement Notes

Verify the exact speed grade suffix against official Lattice documentation, as the provided reference primarily details the -5 variant. Confirm availability status, as older CPLD families may have limited stock or obsolescence notices. Ensure the 256-FTBGA footprint matches the target PCB design constraints.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring significant logic density in a compact surface-mount package. Compare against the LC4512V series if higher operating temperatures or different voltage levels are required. Verify that the 1.65V-1.95V core voltage aligns with the system's power delivery network.

Complex Programmable Logic Devices Part Context

This part is part of the ispMACH 4000C family, which succeeded earlier ispMACH 4000 variants. It offers enhanced performance and lower power compared to previous generations, targeting applications needing robust, reprogrammable logic in space-constrained environments.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other LC4512C variants with different speed grades or package options. Cross-family migration to newer Lattice platforms like MachXO or CrossLink-N may be necessary for long-term supply assurance.
