Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade as per Lattice documentation. Confirm the FT256 package designation matches the required footprint dimensions and ball pitch specifications for PCB layout compatibility. Ensure the source document explicitly lists this part number as active or recommended for new designs.

Complex Programmable Logic Devices Selection Notes

Select this model when a CPLD solution requires ISP capability and non-volatile storage without external configuration flash. Compare the 10 ns speed grade against system timing requirements. Evaluate the 256-pin count against available I/O resources. Consider the FPBGA package constraints regarding thermal dissipation and assembly complexity compared to QFP alternatives.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice MachXO series, which integrates non-volatile configuration technology into CPLD architectures. This series is designed to replace traditional volatile PLDs and PROMs, offering instant-on functionality and reduced system bill of materials by eliminating external configuration devices.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to specific package and speed variations. Verify functional equivalence with other MachXO variants such as LC4256C-10FT256C if commercial grade suffices. Cross-reference with Lattice's official substitution guide for confirmed compatible parts.
