Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating during sourcing. Confirm the FT256 designation matches the required Fine Pitch TQFP footprint. Ensure the supplier provides documentation confirming RoHS compliance and lead-free status as specified in the component parameters.

Complex Programmable Logic Devices Selection Notes

Select this model when a high I/O count PLD is required in a flat package. Compare against the LC4512C series if higher logic density is needed. Verify that the 3.3 V operating voltage aligns with the system's power rails. Check pin compatibility if replacing older CPLD variants.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispLSM 4000/5000/2000E family of EE PLDs. It serves as a drop-in replacement for legacy GAL devices in designs requiring reprogrammability. The C-series denotes commercial or industrial variants depending on the temperature suffix.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may include other Lattice CPLDs from the same family with similar I/O counts. Verify logic capacity and speed grades before substituting. Cross-reference with manufacturer obsolescence notices.
