Complex Programmable Logic Devices Procurement Notes

This specific part number is listed as Discontinued under Product Change Notification (PCN) #09-10. Verification of current availability requires checking official Lattice Semiconductor channels or authorized distributors for remaining stock or obsolescence status. Designers should consider migration strategies due to the discontinuation notice.

Complex Programmable Logic Devices Selection Notes

Select this device if the design requires 1,024 macrocells with 3.3V I/O levels and high-density memory functions within an MFB architecture. Compare against the LC51024MB (2.5V) or LC51024MC (1.8V) variants if different core voltages are required. Ensure the 484-pin fpBGA package fits the board layout constraints.

Complex Programmable Logic Devices Part Context

The LC51024MV belongs to the ispXPLD 5000MX family, which extends the SuperWIDE ispMACH 5000 architecture by adding flexible memory capabilities. This family bridges the gap between traditional CPLDs and FPGAs by offering non-volatile logic with embedded SRAM/FIFO/CAM resources in a single chip.

Complex Programmable Logic Devices Replacement Considerations

Refer to Lattice PCN #09-10 for official replacement recommendations. Potential alternatives within the same density class may include active devices from the ispMACH 5000A series or newer ispXPLD generations, subject to pinout and feature compatibility verification.
