Procurement Notes

Verify the specific suffix 'LTI' against official Lattice documentation to confirm the temperature range and package variant. Ensure compatibility with the programming toolchain, such as Diamond Programmer or Radiant Programmer, for the ispLSI 2000A family. Check for end-of-life status or obsolescence notices prior to procurement.

Selection Notes

Select this component when a non-volatile CPLD with 64 I/Os and high-speed performance is required. Compare against the ISPLSI2064A series for potential pin-compatible upgrades with improved timing specifications. Consider the TQFP package constraints for PCB layout and thermal management during selection.

Part Context

This part belongs to the Lattice ispLSI 2000A family, designed for high-density programmable logic applications. It serves as a successor to earlier GAL devices, offering reprogrammability and higher density while maintaining backward compatibility with standard JEDEC patterns for many functions.

Replacement Considerations

The ISPLSI2064A-100LTI is a functional equivalent within the same family. Verify if the 'A' suffix denotes updated manufacturing processes or minor parameter improvements over the base model.
