Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range compliance (-40°C to +105°C junction temperature). Confirm package details match the 176-pin TQFP specification. Ensure design files are compatible with the ispMACH 4000ZE family tools. Check for any recent product change notices regarding marking or packaging updates from Lattice Semiconductor.

Complex Programmable Logic Devices Selection Notes

Select this component when 384 macrocells are required for moderate complexity designs. The 156 MHz speed grade suits general-purpose logic applications. Consider the TN176 package size constraints during PCB layout. Verify power supply requirements align with the 1.8V core voltage typical for the ispMACH 4000ZE family.

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. The family offers various density options ranging from 32 to 256 macrocells, with the LC4384C representing a higher-density variant within this specific low-power series.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes within the same family include other LC4384C variants with different speed grades or temperature ratings. Cross-family migration to ispMACH 4000V or ZE series may require design resynthesis due to architectural differences.
