Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '75' against official Lattice documentation to confirm the exact speed grade and temperature range, as standard datasheets often list the base model LC4512C with varying speed options. Ensure the FTBGA-256 footprint matches the PCB design requirements. Confirm RoHS compliance status for the specific manufacturing batch.

Complex Programmable Logic Devices Selection Notes

Select this component when high pin count (208 I/O) and low voltage (1.8V) are required simultaneously. Compare against the LC4512V or LC4512Z series if higher speeds (down to 2.5ns) or different voltage levels (3.3V/2.5V) are needed. Verify that the 256-ball BGA package is suitable for the assembly capabilities available.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000C family, which succeeded the ispMACH 4000V/B series. It offers enhanced macrocell flexibility and lower power consumption compared to previous generations. The LC4512C variant specifically targets high-density applications requiring significant logic resources within a compact form factor.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the ispMACH 4000C family such as LC4512C-5FTN256C or LC4512C-10FTN256C, depending on whether timing constraints allow for slower or faster variants. Cross-family migration to ispMACH 4000Z may require schematic adjustments due to voltage differences.
