Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'ZE' to confirm the ultra-low power variant and 1.8V core voltage. Ensure the package type matches the TQFP-100 requirement. Check for moisture sensitivity level (MSL) ratings if reflow soldering is required. Confirm RoHS compliance status for environmental regulations.

Complex Programmable Logic Devices Selection Notes

Select this component when low static power consumption is critical alongside moderate logic density. Compare against the standard LC4128Z series if higher speed or different voltage levels are needed. Consider the 100-pin TQFP package constraints for board layout. Verify that the 64 I/O count meets the system interface requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000ZE family, an evolution of the 4000Z architecture. It combines high speed with reduced power consumption. The family is known for pin-out retention and density migration capabilities, making it suitable for upgrading existing designs without major hardware changes.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other members of the ispMACH 4000ZE family with similar macrocell counts. The LC4128ZE-5TQ100C may be considered if package variations are acceptable. Verify electrical specifications match before substitution.
