Complex Programmable Logic Devices Procurement Notes

Verification of component authenticity is critical due to the prevalence of counterfeit programmable logic devices. Buyers should request original manufacturer documentation or certified distributor traceability records. Confirm that the part number suffix matches the specific speed grade and package variant required for the design.

Complex Programmable Logic Devices Selection Notes

Select this model when a low pin count CPLD with moderate speed is required. The 5 ns delay and 250 MHz frequency suit most synchronous logic designs. Ensure the 1.8 V core voltage aligns with the system power budget, as it differs from older 3.3 V or 2.5 V variants in the same family.

Complex Programmable Logic Devices Part Context

This component is part of the ispMACH 4000Z series, which offers high-density logic in small packages. It shares architectural similarities with the 4064C and 4064E variants but features optimized performance characteristics for 1.8 V applications. The Z series typically targets cost-sensitive designs requiring reliable non-volatile configuration.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package include other LC4064Z variants with different speed grades, such as LC4064ZC-5T48I or LC4064ZE-5TN48C, provided timing requirements are met. Cross-family migration to newer Lattice platforms requires schematic and code adaptation.
