Complex Programmable Logic Devices Procurement Notes

Verify the suffix 'T' against official Lattice documentation to confirm the specific package variant, as datasheets often list 'TN' or 'FT' for this pin count. Confirm the temperature grade 'I' corresponds to the Industrial range (-40°C to +105°C). Ensure the design tool version supports the ispMACH 4000V family for programming.

Complex Programmable Logic Devices Selection Notes

Select this model when 512 macrocells are required with high-speed performance (400 MHz). Compare with the LC4512C series if lower cost is prioritized over speed, noting that the C series typically has slower delays. Ensure the PCB layout accommodates the 176-pin TQFP footprint and thermal requirements for the selected temperature grade.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000V family, designed for high-density, high-performance applications. It succeeds earlier generations by offering improved speed and lower power consumption while maintaining compatibility with existing ispMACH design flows. The 4000V series is characterized by its non-volatile Flash technology, allowing instant-on functionality without external configuration memory.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements within the same family include the LC4512V-5TN176I or LC4512V-5FT176I, depending on the required package type (TQFP vs. Fine-pitch BGA). Cross-family upgrades may involve the ispMACH 4000ZE series for enhanced density.
