Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '4TN48C' against official Lattice documentation to confirm pinout and thermal characteristics. Note that availability status may vary; check current lifecycle notifications as components may be subject to change or obsolescence. Ensure compliance with RoHS directives and moisture sensitivity levels prior to assembly. Confirm that the 1.8 V core voltage aligns with your system's power supply architecture.

Complex Programmable Logic Devices Selection Notes

Select this device when designing systems requiring moderate logic density with guaranteed timing predictability. The 48-pin TQFP package suits applications with space constraints but needing through-hole or standard SMT compatibility. Consider the 1.8 V core requirement for power budgeting and ensure I/O voltages match the 5 V tolerant specification if interfacing with older standards. Evaluate the 241 MHz speed grade against your maximum clock requirements.

Complex Programmable Logic Devices Part Context

This component belongs to the ispMACH 4000ZE family, which combines the architecture of ispLSI 2000 and ispMACH 4A devices. The ZE series emphasizes low power consumption and high performance, targeting applications where energy efficiency and reliable operation are critical. It serves as a non-volatile programmable logic solution for designers migrating from discrete gate arrays or PALs.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include other members of the LC4064ZE series with different package options, such as the LC4064ZE-4UMN64C in a UCBGA-64 package. Verify that alternative packages maintain the same 64 macrocell count and I/O capabilities. Cross-referencing with the LC4000ZE datasheet is essential to ensure pin-to-pin compatibility or necessary board redesigns.
