Complex Programmable Logic Devices Procurement Notes

This component is identified as obsolete or end-of-life status in public distributor records. Verification of current availability requires checking authorized Lattice distributors for remaining stock or obsolescence notices. Designers should confirm lead times and potential discontinuation risks before finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select this model when a high pin count CPLD with 3.3V I/O levels is required. Ensure the design accommodates the 3.0V to 3.6V supply range. For lower power applications, consider the 1.8V ispMACH 4000ZE or 4000C families instead.

Complex Programmable Logic Devices Part Context

The LC4384V-5F256C is part of the ispMACH 4000V family, which targets high-performance applications requiring fast I/O response. It succeeds earlier generations like the 4000VE series and offers improved speed grades compared to standard commercial variants.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are not publicly documented for this specific obsolete part number. Consider the LC4384C-5FN256C for similar density but note the voltage difference (1.8V vs 3.3V). Verify compatibility with existing board designs if migrating to newer Lattice CPLD families.
