Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'FTN' against official datasheets, as standard listings often use 'FTBGA'. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as availability varies by region. Check for End-of-Life notifications prior to procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when a 5ns speed grade is required for 256-macrocell designs. Ensure the PCB layout accommodates the 256-ball FineLine BGA footprint. Verify that the 1.8V power domain aligns with the system's voltage requirements compared to older 2.5V variants.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000CE series, designed for low-power, high-density CPLD applications. It utilizes Lattice's non-volatile CMOS technology, allowing for instant-on functionality without external configuration memory.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other speed grades within the same package such as the LC4256C-7FTN256BI or LC4256C-10FTN256BI. Cross-family migration may require retiming adjustments.
