Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific part number matches the required automotive grade specifications and package type. Ensure compliance with RoHS directives and check for any recent product change notices affecting availability or specifications before finalizing procurement decisions.

Selection Notes

Select this component when designing systems that require certified automotive reliability combined with moderate logic density. The 3.3 V supply requirement must align with the target system's power rails. Consider the TQFP-48 package constraints regarding pin count and physical footprint during the initial hardware layout phase to ensure compatibility with the intended application board design.

Part Context

This CPLD is part of the broader ispMACH 4000V series, which provides non-volatile configuration capabilities. The series is designed to replace complex discrete logic solutions, offering reprogrammability and reduced board space. It serves as a versatile solution for control applications where deterministic timing and low latency are critical operational requirements.

Replacement Considerations

Direct substitutes within the same family include variants with different pin counts such as LA4064V-75TN44E or LA4064V-75TN100E. Cross-family replacements may require significant schematic and firmware modifications due to differences in logic resources and I/O configurations.
