• Features high-speed performance with a 7.5ns propagation delay and 400MHz maximum frequency.
• Includes JTAG boundary scan support for enhanced manufacturing testability.

Applications

• Power-sensitive consumer electronics applications
• General-purpose digital logic control systems
• Interface bridging between different voltage domains

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range compliance against your project requirements. Confirm that the 48-pin TQFP footprint matches your PCB layout constraints. Ensure the design toolchain supports the ispMACH 4000ZE architecture for proper synthesis and implementation. Check RoHS compliance status if environmental regulations are strict for your target market.

Selection Notes

Select this model when a moderate density of 32 macrocells is sufficient for the logic requirements. It is suitable for designs requiring low power consumption due to the available 1.8V operation option. Consider this part if in-system reprogramming capabilities are necessary for field updates. Evaluate the 7.5ns speed grade against the timing constraints of the target application to ensure signal integrity.

Part Context

This component belongs to the Lattice ispMACH 4000ZE series, which focuses on super-fast, high-density PLDs. The series is characterized by its ability to operate across multiple voltage levels, making it adaptable for various legacy and modern interface standards. The ZC variant typically denotes specific speed and package combinations within the broader 4000ZE family lineup.

Replacement Considerations

Direct substitutes within the same family include LC4032ZC-75T48C for commercial temperature range variants. Cross-family replacements may involve other Lattice CPLDs with similar macrocell counts but different speed grades or package types. Verify pinout compatibility before substituting with devices from other manufacturers.
