Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm it denotes the commercial temperature grade. Ensure the package type matches the required 176-pin TQFP footprint. Check for RoHS compliance status as older revisions may differ from current manufacturing standards.

Complex Programmable Logic Devices Selection Notes

Select this component when 384 macrocells are sufficient for the design complexity. Consider the 260 MHz speed limit for timing closure. Compare against the LC4384V series if higher speeds or industrial temperature ranges are required. Verify pin compatibility with existing board layouts.

Complex Programmable Logic Devices Part Context

This part is part of the ispMACH 4000ZE family, which focuses on ultra-low power consumption while maintaining high performance. It combines elements of the ispLSI 2000 and ispMACH 4A architectures, offering robust global routing and predictable timing characteristics for complex digital designs.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other LC4384 variants with different speed grades or temperature ratings. Cross-family migration to newer Lattice CPLDs like the MachXO3 series may require significant redesign due to architectural differences.
