Complex Programmable Logic Devices Procurement Notes

Verify component status prior to procurement. Product Change Notification (PCN) #09-10 indicates that select devices in the ispXPLD 5000MX family have been discontinued. While the LC5512MV series is listed as Active/Orderable in some contexts, cross-reference the specific suffix and date code with official Lattice documentation to confirm current availability and lifecycle status.

Complex Programmable Logic Devices Selection Notes

Select this device for designs requiring mixed logic and memory density. The 512 macrocell count suits moderate complexity applications. Ensure voltage compatibility; the 'MV' suffix denotes 3.3V core operation. Verify I/O bank requirements against supported standards like LVCMOS 3.3V and 5V tolerance. Consider thermal dissipation given the static current specifications for 3.3V operation.

Complex Programmable Logic Devices Part Context

This part belongs to the ispXPLD 5000MX family, which extends the SuperWIDE ispMACH 5000 architecture. The family includes variants with different densities (5256, 5512, 5768, 51024 macrocells) and voltage cores (MV for 3.3V, MB for 2.5V, MC for 1.8V). The LC5512MV specifically targets 3.3V applications with 512 macrocells.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements are limited due to the discontinued status of parts in this family. Check Lattice's current CPLD portfolios such as the MachXO or CrossLink families for modern equivalents. Migration requires re-evaluation of pinout, power, and feature sets.
