Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'T' against official Lattice documentation to confirm the package type corresponds to TQFP-176. Ensure the operating temperature range matches the 'I' industrial designation (-40°C to +85°C). Confirm RoHS compliance status as required by project specifications.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require 512 macrocells and 128 I/Os in a surface-mount TQFP package. Compare against the LC4512C-10 variant if lower speed requirements allow for cost optimization. Verify that the 3.3V I/O levels are compatible with the target system interfaces.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000C family, which succeeded the ispMACH 4000B series. It offers improved performance and density compared to earlier generations while maintaining backward compatibility with existing design tools and pinouts where applicable.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other members of the LC4512C family with different speed grades or package options, such as LC4512C-5TN176I. Cross-family upgrades may involve the LC4000Z series for lower voltage operation.
