Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'TN144' against the requested model, as datasheets indicate TQFP-144 packaging. Confirm humidity sensitivity handling requirements during storage and assembly. Ensure design tools support the ispMACH 4256V family for accurate timing analysis and programming. Check for recent product change notifications regarding pinout or electrical characteristics updates.

Complex Programmable Logic Devices Selection Notes

Select this component when moderate logic density is required with low power constraints. Compare against the LC4256ZE series if lower voltage operation (1.8V) is necessary instead of 3.3V. Consider the LC4128V if fewer macrocells suffice for the design complexity. Verify that the TQFP-144 footprint meets board space limitations compared to smaller packages like TQFP-100.

Complex Programmable Logic Devices Part Context

This part belongs to Lattice's ispMACH 4256V family, designed for cost-effective, low-power programmable logic solutions. It serves as a successor to earlier ispMACH devices, offering improved performance per milliwatt. The family targets applications requiring flexible logic replacement for discrete components or ASIC prototyping.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other variants within the LC4256V family with different package options such as LC4256V-75TN100I. Cross-family migration to LC4256ZE requires voltage level adjustment. Verify pin compatibility before substituting with older ispMACH 4000 series parts.
