Complex Programmable Logic Devices Procurement Notes

Verify product status prior to procurement. Product Change Notification PCN#09-10 indicates that select devices within this datasheet have been discontinued. Confirm current availability through authorized distributors or Lattice Semiconductor directly, as supply may be limited or end-of-life depending on the specific revision.

Complex Programmable Logic Devices Selection Notes

Select the LC5512MV variant specifically for 3.3V core voltage requirements. Ensure the design fits within the 512 macrocell limit and 193 I/O constraint. For lower power needs, consider the 1.8V (MC suffix) or 2.5V (MB suffix) variants if voltage compatibility allows. Verify package availability, as the PQFP form factor may have fewer options compared to BGA packages.

Complex Programmable Logic Devices Part Context

This part belongs to the ispXPLD 5000MX family, which extends the traditional CPLD architecture by integrating significant embedded memory capabilities. Unlike standard CPLDs, these devices offer true dual-port SRAM and Ternary CAM modes within their Multi-Function Blocks, bridging the gap between simple programmable logic and more complex FPGA solutions.

Complex Programmable Logic Devices Replacement Considerations

Check PCN#09-10 for discontinuation status. Potential replacements include other members of the ispXPLD 5000MX family with similar density (e.g., LC5768MV) or migration to modern Lattice ECP5 or MachXO3 families for new designs, subject to pinout and feature compatibility verification.
