• Features 5 V tolerant I/Os compatible with LVCMOS 3.3, LVCMOS 2.5, LVCMOS 1.8, LVTTTL, and PCI interfaces.
• Provides high-performance logic with up to 80 product terms per output pin.

Complex Programmable Logic Devices Applications

• High-density programmable logic applications requiring low power consumption.
• Interface bridging between different voltage domains in embedded systems.
• Replacement for legacy GAL or PAL devices in industrial control designs.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'ZE' against official Lattice documentation to confirm it denotes the 1.8 V core voltage variant within the ispMACH 4000 series. Ensure the package type matches the required 144-pin TQFP form factor. Confirm RoHS compliance status through the manufacturer's current datasheet, as packaging and marking changes may occur over time.

Complex Programmable Logic Devices Selection Notes

Select this component when a balance of moderate density (128 macrocells) and high speed (333 MHz) is required. The 1.8 V core voltage offers lower dynamic power compared to 3.3 V variants. Consider the 144-pin TQFP package for surface-mount assembly needs. Verify that the 5 V tolerant I/Os meet the system's interface requirements without additional level shifting.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000V/B/C/Z family, which integrates architectures from previous ispLSI 2000 and ispMACH 4A lines. The family is designed for superfast performance with global clock pins and predictable timing. The LC4128ZE specifically targets applications needing 1.8 V operation while maintaining compatibility with higher voltage I/O standards.

Complex Programmable Logic Devices Replacement Considerations

Publicly confirmed substitutes include other members of the ispMACH 4000V/B/C/Z family with similar macrocell counts, such as the LC4128V or LC4128Z series. Check if the alternative part number shares the same 144-pin TQFP package and 1.8 V core voltage requirement to ensure pin-to-pin and functional compatibility.
