Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'FT256' against official Lattice documentation to confirm the package type and pinout, as datasheets may list variations such as F256 or FTN256. Ensure the temperature grade 'I' matches the required operational environment. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Complex Programmable Logic Devices Selection Notes

Select this model when a high I/O count (208 pins) and moderate logic density (512 macrocells) are required in a compact FBGA footprint. Compare against the LC4512V series if lower power consumption is critical, noting potential differences in performance specifications. Verify that the 3.3V I/O standards meet the system's voltage requirements without level shifting.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice MachXO family of CPLDs, which are known for low power and non-volatile configuration. It serves as a successor to older GAL and PAL devices, offering reprogrammability and higher complexity. The LC4512C variant specifically targets cost-sensitive applications while maintaining robust performance characteristics typical of the MachXO line.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other LC4512 variants with compatible packages, such as LC4512V-10FTN256I, provided pin compatibility and electrical parameters align. Verify that any substitute maintains the same I/O count and logic capacity to ensure functional equivalence in the design.
