Procurement Notes

Verify the specific suffix 'E' against official Lattice documentation to confirm it denotes the extended temperature range (-40°C to +125°C) and automotive grade status. Ensure the datasheet matches the exact part number LC4032V-75TN44E, as variations in suffixes may indicate different packaging or speed grades. Cross-reference with the manufacturer's current product selector guide for availability and lifecycle status.

Selection Notes

Select this component when designing systems requiring automotive-grade reliability with moderate logic density. The 32 macrocell count suits simple state machines and glue logic applications. Verify that the 3.3 V operating voltage aligns with the target system's power rails. Consider the 44-pin TQFP footprint for PCB layout constraints and ensure thermal management supports the specified junction temperature limits.

Part Context

This part belongs to the Lattice ispMACH 4000V/Z Auto Family, designed for high-reliability applications. It shares architectural similarities with other members like the LA4064V and LC4032V series but is distinguished by its specific macrocell count and automotive certification. The 'V' indicates the voltage family, while 'TN44' specifies the TQFP-44 package type.

Replacement Considerations

Direct pin-compatible replacements within the same family include the LA4032V-75TN44E if available. For non-automotive applications, the LC4032V-75TN44C offers similar electrical characteristics but lacks the extended temperature range and automotive qualification. Verify compatibility with existing design tools before substitution.
