Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to the device's obsolete status. Confirm lead-free compliance requirements as original specifications may contain lead. Ensure compatibility with programming tools such as ispDOWNLOAD programmers. Validate package integrity upon receipt, as long-term storage may affect solderability. Check for specific RoHS exemptions if required by final assembly standards.

Complex Programmable Logic Devices Selection Notes

Select this model when 384 macro cells are sufficient for the target logic density. Choose the T176 suffix for 176-pin TQFP packaging constraints. The -10 speed grade suits designs requiring approximately 10 ns delays. Consider the -I suffix for industrial temperature operation. Evaluate pin count availability against I/O requirements before selecting alternative packages like FT256.

Complex Programmable Logic Devices Part Context

This component is part of Lattice Semiconductor's ispMACH 4000V family, which blends architectures from the ispLSI 2000 and ispMACH 4A series. The family emphasizes first-time-fit success and routing efficiency through its dedicated routing pools. It serves as a non-volatile CPLD solution designed for applications demanding both flexibility and deterministic timing performance.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other devices within the LC4384V series with compatible pin counts or speed grades. Cross-reference pinouts when considering packages with different footprints, such as the FTBGA variant. Verify that replacement parts maintain the same macro cell count and voltage specifications to ensure functional equivalence in existing designs.
