Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'T' against official Lattice documentation to confirm package type accuracy, as standard datasheets often list 'TN' for TQFP variants. Confirm RoHS compliance status and lead-free finish specifications directly from the manufacturer's current product selector guide or datasheet revision notes prior to procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when 512 macrocells are required with a 5 ns speed grade. Ensure the design accommodates the 3.3 V nominal supply voltage and 176-pin footprint. Compare against the LC4512C series if lower power consumption is critical, noting that the 'V' suffix denotes the specific generation within the ispMACH 4000 family.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, which offers high-density PLDs with low power consumption. It is designed for applications requiring fast path performance and wide input gating capabilities. The family supports multiple temperature ranges, including commercial (0°C to 90°C) and industrial (-40°C to 105°C) junction temperatures.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package may include other members of the ispMACH 4000V family with similar macrocell counts, such as the LC4512V-5TN176C, provided the suffix difference does not alter electrical characteristics or package dimensions.
