Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to 105°C). Confirm the package type matches the required footprint, as variations exist between TQFP and other formats. Check for recent Product Change Notifications regarding marking or assembly site changes. Ensure compatibility with existing programming tools like ispDOW for configuration.

Complex Programmable Logic Devices Selection Notes

Select this component when 128 macrocells are sufficient for the logic density needs. The 7.5 ns speed grade suits applications requiring moderate timing margins. Compare against the LC4128V-5 variant if faster performance is required, noting potential pinout or power differences. Ensure the 144-pin form factor fits the mechanical constraints of the target enclosure.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V family, designed for high-density, low-power CPLD applications. It complements Lattice's broader portfolio by offering non-volatile programmability with high reliability. The family supports multiple voltage domains, facilitating integration into mixed-signal environments common in modern electronic designs.

Complex Programmable Logic Devices Replacement Considerations

The LC4128V-5TN144C is a documented alternative within the same family, offering similar functionality but potentially different speed grades or commercial temperature ratings. Verify that the substitute meets all environmental and timing requirements before substitution.
