Complex Programmable Logic Devices Applications

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence or limited availability. Confirm that the specific suffix TN100C corresponds to the required TQFP-100 package and commercial temperature grade before procurement. Cross-reference datasheet revisions to ensure compatibility with existing design specifications.

Complex Programmable Logic Devices Selection Notes

Select this model when a high-density CPLD with 64 macrocells and 64 I/Os is required in a TQFP-100 footprint. Ensure the system design accommodates the 2.5 V power domain and the 0°C to +90°C operating temperature range. Compare against the LC4064V series if industrial temperature ratings (-40°C to +105°C) are necessary instead.

Complex Programmable Logic Devices Part Context

This component belongs to the Lattice ispMACH 4000B family of CPLDs. It shares architectural similarities with other members like the LC4064B-75T100I and LC4064V-75TN100I, differing primarily in temperature rating and voltage tolerance. The 'C' suffix typically denotes the commercial temperature grade variant within this product line.
