Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this specific part number may be obsolete or end-of-life. Confirm that the TQFP-176 package matches current board layout requirements. Check for lead compliance status, as older revisions may not meet current RoHS standards. Ensure design-in documentation confirms compatibility with modern programming tools for legacy CPLDs.

Complex Programmable Logic Devices Selection Notes

Select this device when 384 macro cells are sufficient for the logic density requirement. The 322 MHz speed grade suits moderate-to-high frequency synchronous designs. Choose the TQFP-176 package if surface-mount technology with peripheral pins is preferred over ball grid arrays. Consider the 3.3V I/O compatibility for interfacing with standard logic families.

Complex Programmable Logic Devices Part Context

This component is part of Lattice's ispMACH 4000V family, which blends the ispLSI 2000 and ispMACH 4A architectures. It targets applications requiring flexible, low-power programmable logic with high reliability. The family is designed for first-time-fit success and offers migration paths within the CPLD portfolio.

Complex Programmable Logic Devices Replacement Considerations

Public sources indicate the LC4384V-5T176I is obsolete. Verify official Lattice recommendations for direct functional equivalents within the ispMACH 4000 series or newer CPLD families. Ensure any substitute maintains the 176-pin TQFP footprint or requires PCB redesign.
