Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range (-40°C to +85°C) against the manufacturer's official datasheet. Confirm the 'FTN256' designation corresponds to the FineLine BGA-256 package dimensions and pinout. Ensure the component status is active or obsolescence notices are reviewed prior to procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this model when 512 macrocells and high I/O count are required in a compact BGA footprint. Compare against the LC4512V series if higher speed grades or different voltage options are needed. Verify that the 3.3V supply requirement aligns with the target system's power rails and that the 5 ns delay meets the timing constraints of the application.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000C CPLD family, designed for high-performance, low-power applications. It serves as a successor to earlier ispMACH generations, offering increased density and speed. The LC4512C variant specifically targets cost-sensitive applications requiring robust logic capabilities without the complexity of FPGA development flows.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package may include other members of the LC4512C family with different speed grades (e.g., -7, -10). Cross-family migration to LC4512V requires verification of electrical parameter compatibility and package availability.
