Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation, as standard datasheets often list the 'V' variant. Confirm that the TQFP-100 package and Industrial temperature grade (-40°C to +105°C) match the design requirements. Ensure the 3.3V core voltage specification aligns with the target system power rails before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when 256 macrocells are sufficient for the design complexity. The 7.5 ns speed grade offers high performance for general-purpose logic. Consider the TQFP-100 package if surface mount space allows. Verify compatibility with existing programming tools such as Lattice Diamond or ispLEARN Classic for configuration.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V series, designed for low-power, high-performance applications. It utilizes Lattice's non-volatile Flash technology, allowing for infinite reprogrammability without external configuration memory. The series is known for robust ESD protection and ease of use in embedded systems.

Complex Programmable Logic Devices Replacement Considerations

The LC4256V-75T100I is a documented equivalent within the same family. Verify pinout and electrical specifications between the 'C' and 'V' variants to ensure functional interchangeability.
