Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'V' indicates the commercial temperature grade (-0°C to +70°C) and '25' denotes the 2.5 ns speed grade. Confirm the 'T100C' specifies the 100-pin Thin Quad Flat Package with lead-free termination. Ensure the manufacturer documentation matches the exact part number to avoid confusion with similar MachXO variants that may have different pin counts or performance characteristics.

Complex Programmable Logic Devices Selection Notes

Select this component when a small number of macrocells is sufficient for glue logic applications requiring non-volatile storage. The 100-pin TQFP package offers a balance of I/O density and board space. Consider the 2.5 ns delay if timing constraints are tight for simple synchronous designs. Verify power supply requirements align with the 2.5V nominal operating voltage before finalizing the design.

Complex Programmable Logic Devices Part Context

This part belongs to Lattice's MachXO series, which bridges the gap between simple PLDs and larger FPGAs. It utilizes Flash-based technology, eliminating the need for external configuration chips common in SRAM-based FPGAs. The MachXO family is designed for cost-sensitive applications where low power and instant-on functionality are critical.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements should be sought within the same MachXO family with equivalent or higher macrocell counts, such as the LC4064V-25TQ100C. Verify pin compatibility and I/O voltage levels. Cross-reference with other manufacturers' CPLDs only if functional equivalence and package dimensions match exactly.
