Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +105°C) as per Lattice documentation. Confirm the package marking and pinout match the 100-TQFP specification. Ensure compatibility with standard JTAG programming interfaces for in-system configuration. Check for RoHS compliance status if required by assembly standards.

Complex Programmable Logic Devices Selection Notes

Select this component when 128 macrocells are sufficient for the logic density requirements. The 7.5 ns speed grade offers a balance between performance and power consumption. Consider the 100-pin TQFP package for surface-mount assembly constraints. Verify that the 1.8V core voltage aligns with the target system's power architecture.

Complex Programmable Logic Devices Part Context

This part belongs to the ispMACH 4000Z family, designed for ultra-low power applications. The Z series specifically targets 1.8V operation while maintaining high performance. It serves as a drop-in replacement for older GAL devices and other CPLDs in designs requiring non-volatile reprogrammability and low standby current.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other variants within the LC4128ZC series with different package options or speed grades. Cross-family migration to the ispMACH 4000ZE may offer lower power but requires verification of pin compatibility and feature parity.
