Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'B' against official Lattice documentation to confirm temperature range and voltage compatibility. Ensure the TN44 package designation matches the required TQFP footprint and pin pitch. Cross-reference the part number with the manufacturer's current product status to confirm availability and lifecycle stage before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component when 64 macrocells are sufficient for the design complexity. The 10ns speed grade offers a balance between performance and power consumption. Consider the 44-pin TQFP package constraints regarding PCB space and thermal dissipation. Verify that the required I/O count does not exceed the 30 available lines after accounting for dedicated inputs.

Complex Programmable Logic Devices Part Context

This CPLD is part of the ispMACH 4000V/B/C/Z family, which provides high-density programmable logic solutions. The family is characterized by non-volatile configuration memory and low power consumption. It serves as a successor to earlier PLD technologies, offering enhanced flexibility and reprogrammability for modern digital designs.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include LC4064C-10TN44I or LC4064Z-10TN44I, provided pinout and electrical characteristics remain compatible. Verify functional equivalence and timing parameters before substitution.
