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 some variants remain active, specific ordering suffixes may be obsolete. Confirm current availability and lifecycle status directly with authorized distributors or Lattice Semiconductor before finalizing design-in decisions.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring deterministic timing and high I/O density in a single chip. The 45 speed grade offers a balance between performance and power consumption compared to faster grades. Ensure the design utilizes the 3.3V core voltage. Consider the 484-pin fpBGA package constraints for PCB layout. Verify if the 512 macrocell density meets logic requirements or if higher-density members like the LC5768MV are needed.

Complex Programmable Logic Devices Part Context

This component is part of the ispXPLD 5000MX family, which extends the traditional CPLD architecture by integrating significant on-chip memory resources. Unlike standard PLDs, these devices allow designers to implement complex state machines, arithmetic functions, and memory buffers within a single programmable fabric. The family includes variants with different voltages (3.3V, 2.5V, 1.8V) and densities.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other ispXPLD 5000MX devices such as the LC5512MV-75FN484C (slower speed grade) or LC5768MV series (higher density). Note that PCN #09-10 lists several 5000MX devices as discontinued; verify if the specific -45 speed grade variant remains orderable or if migration to a newer Lattice platform like CrossLink-N or MachXO3 is required.
