Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'TN44I' against official Lattice documentation to confirm package type (TQFP), pin count (44), and industrial temperature rating. Ensure compatibility with design tools supporting the ispMACH 4000V/B/C/Z family. Check for end-of-life status or alternative recommendations from the manufacturer before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when a high-density CPLD with fast propagation delays is required in a compact 44-pin package. The 64 macrocell count suits moderate complexity logic designs. Verify that the target application requires ISP functionality and operates within the supported voltage ranges (1.8V–3.3V). Consider the industrial temperature grade if the environment exceeds commercial limits.

Complex Programmable Logic Devices Part Context

This part belongs to the Lattice ispMACH 4000V/B/C/Z family, which provides non-volatile configuration memory (NVCM) allowing instant-on operation without external configuration devices. The family is designed for applications requiring low power consumption, high performance, and flexible I/O options across various packaging styles.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same density and package may include other variants from the LC4064C series with different speed grades or temperature ratings. Cross-family migration to newer Lattice architectures like MachXO or iCE40 requires significant design re-verification due to architectural differences.
