Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix TN48I confirms the TQFP-48 package and industrial temperature grade (-40°C to +105°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the 1.8V core voltage requirements and supported I/O standards.

Complex Programmable Logic Devices Selection Notes

Select this component when 64 macrocells are sufficient for the logic density requirements. The TQFP-48 package is suitable for surface-mount assembly where moderate pin counts are needed. Consider the 4.7 ns propagation delay for timing-critical paths. Verify that the target system can provide the required 1.8V core supply voltage.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000ZE series, which enhances the original 4000Z architecture. The series focuses on combining high speed with low power consumption. It is designed for applications needing flexibility, density migration, and reliable performance in industrial environments.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements must match the 64 macrocell count, TQFP-48 package, and industrial temperature range. Verify electrical compatibility regarding the 1.8V core voltage and I/O levels. Cross-reference with other LC4064ZE variants if package or speed grade adjustments are permissible.
