Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' against official Lattice documentation to confirm lead-free status and RoHS compliance. Confirm that the 100-TQFP package matches the target PCB footprint dimensions. Ensure the 3.3V supply rail aligns with the specified operating voltage range before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when 128 macrocells are sufficient for the logic density requirements. The 5 ns speed grade offers a balance between performance and power consumption compared to faster variants. Consider the 100-pin package availability if space constraints allow for surface-mount installation.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, designed for high-density, low-power applications. It serves as a successor to earlier CPLD generations, offering improved performance and reduced power usage while maintaining compatibility with existing design tools and methodologies used for legacy Lattice devices.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other members of the LC4128V series with compatible pinouts, such as the LC4128V-7T100C or LC4128V-10T100C, provided the timing requirements allow for slower speeds. Verify that any alternative maintains the same 100-pin TQFP form factor.
