Complex Programmable Logic Devices Procurement Notes

Verify moisture sensitivity level handling requirements prior to assembly, as the component is sensitive to humidity. Confirm that the specific suffix MN144 corresponds to the CSBGA-144 package variant required for your PCB footprint. Ensure design tools support the ispMACH 4256ZE family for accurate place-and-route results. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement specifications.

Complex Programmable Logic Devices Selection Notes

Select this part when high I/O count (108) is needed alongside low power constraints. Compare against the TN144 variant if a TQFP package is preferred over CSBGA. Consider the 7 speed grade only if 7.5 ns propagation delay meets timing closure requirements. Verify that 1.8V supply rails are available on the target system board.

Complex Programmable Logic Devices Part Context

This CPLD belongs to the ispMACH 4256ZE series, designed for cost-sensitive, low-power applications. It serves as a drop-in replacement for older GAL devices in many legacy designs while offering significantly higher density. The ZE series emphasizes reduced power dissipation compared to previous generations, making it ideal for modern energy-efficient electronic designs.

Complex Programmable Logic Devices Replacement Considerations

The LC4256ZE-7TN144I offers identical electrical performance but uses a TQFP-144 package instead of CSBGA-144. Pin compatibility differs between packages; verify schematic netlists carefully. No other direct functional substitutes are confirmed in public documentation.
