• Features EEPROM/SRAM non-volatile configuration storage.
• Available in a 484-pin FPBGA package suitable for SMD/SMT mounting.

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems.
• Address bus buffering and protocol conversion in computing infrastructure.
• Complex glue logic integration for mixed-signal circuit designs.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '75' corresponds to the required speed grade, as variations exist within the LC5512B series. Confirm the FPBGA-484 package availability, as pin counts and package types differ across similar model numbers. Check moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure the design accounts for the 2.5V core voltage requirements specified in the datasheet.

Complex Programmable Logic Devices Selection Notes

Select this component when 512 macrocells are sufficient for the design logic density. Compare against the LC51024MB for higher capacity needs or the LC5768MC for increased I/O counts. Verify that the 250 MHz performance meets timing constraints. Consider the EEPROM/SRAM storage type for non-volatile configuration retention without external memory devices.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispXPLD family, which bridges the gap between traditional PLDs and FPGAs. The LC5512B variant specifically offers a balance of moderate logic density and high performance. It is distinct from the Flash-based MachXO series and the larger ispMACH 4000 families, targeting applications requiring deterministic timing and low power consumption.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other LC5512B variants with different speed grades or temperature ranges. Cross-family migration may require retiming adjustments due to differences in architecture between CPLD and FPGA technologies.
