Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications prior to procurement. Ensure proper handling for moisture-sensitive devices during storage and assembly processes.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 macrocells are sufficient for the design requirements. Compare against the LC4064B and LC4064C series variants based on specific speed grades (e.g., -75, -10) and voltage requirements (1.8V vs 2.5V). Verify that the TQFP-48 package fits the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000ZE family, designed for high-density, low-power applications. It serves as a successor to earlier ispMACH 4000 variants, offering improved performance and density within a compact form factor suitable for embedded systems requiring flexible programmable logic.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements include other members of the LC4064 family such as LC4064B-5TN48I or LC4064C-5TN48I, provided voltage levels and timing requirements match. Cross-family migration to higher density CPLDs may require schematic and code adjustments.
