Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +105°C) as defined by Lattice Semiconductor. Confirm the package type corresponds to the CSBGA-132 form factor. Check for moisture sensitivity level requirements during storage and handling. Ensure compatibility with the intended programming toolchain for ispMACH devices.

Complex Programmable Logic Devices Selection Notes

Select this component when 128 macrocells are sufficient for the logic density requirements. Compare against the LC4256ZE series if lower power is critical, or the LC4256V series if 3.3V operation is required. Consider the TQFP-100 variant if leaded packaging is preferred over ball grid array solutions. Verify pin count matches the PCB footprint constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000Z family, designed for low-power applications. It serves as a successor to older GAL technologies, offering higher density and reprogrammability. The ZC variant specifically targets cost-sensitive markets while maintaining high performance. It complements Lattice's FPGA portfolio by providing deterministic logic for simpler control tasks.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the ispMACH 4000Z family with equivalent macrocell counts. Cross-reference pinouts carefully when substituting with TQFP versions. Verify that alternative CPLDs support the same voltage levels and programming interfaces.
