Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors. Confirm that the specific ordering suffix matches the required voltage and temperature grade. Check for Product Change Notifications (PCNs) regarding lifecycle status, as select devices in this family have been discontinued. Ensure handling procedures account for moisture sensitivity levels specified in the datasheet.

Complex Programmable Logic Devices Selection Notes

Select the LC51024MV variant specifically for designs requiring a 3.3V core supply voltage. Compare against the LC51024MB (2.5V core) and LC51024MC (1.8V core) if lower power consumption is prioritized over the 3.3V compatibility. Ensure the design fits within the 1,024 macrocell limit and verify that the 484-pin fpBGA package aligns with PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the ispXPLD 5000MX family, which extends the traditional CPLD architecture by integrating significant on-chip memory capabilities. Unlike standard PLDs, these devices allow designers to implement complex state machines alongside substantial RAM or CAM structures within a single chip, reducing overall system component count.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements are limited due to the discontinuation of several variants in the 5000MX family. Consider the LC51024MB-75FN484I if a 2.5V core is acceptable, or evaluate newer Lattice families such as MachXO or CrossLink for modern feature sets. Verify pinout compatibility before substituting with other density levels like the LC5768MV.
