Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized Lattice distributors. Confirm RoHS compliance status as older batches may contain lead. Check for Obsolete status indicators, as availability may be limited to stock or last-time buy scenarios. Ensure packaging matches the specified TQFP-176 form factor. Validate that the suffix 'TN' corresponds to the correct temperature grade and package variant required for your specific application environment.

Complex Programmable Logic Devices Selection Notes

Select this device when 384 macrocells are sufficient for the design complexity. Compare against the LC4384C series if lower power consumption at 1.8V is required, noting potential differences in I/O standards. Consider the LC4384V-35 variant if higher speed (35ns vs 75ns) is needed, though density remains similar. Evaluate pin count requirements carefully, as the 176-pin package offers 128 I/O lines. Ensure the design tool suite supports the ispMACH 4000V family for programming and simulation.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4000V family, which blends architectures from the ispLSI 2000 and ispMACH 4A series. It is positioned as a high-density, superfast PLD solution. The family emphasizes first-time-fit success and ease of migration between devices. It serves as a bridge between simple programmable logic and more complex FPGA solutions, offering non-volatile configuration and deterministic timing.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the ispMACH 4000V family such as the LC4384V-35TN176C for faster performance. Cross-family migration to the LC4000ZE series is possible but requires verification of voltage compatibility and feature mapping. Legacy equivalents like the ispLSI 2000AE series may require significant redesign due to architectural differences. Always verify pinout compatibility and I/O drive strengths when substituting.
