Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or Lattice Semiconductor directly. Confirm the specific suffix 'I' denotes the Industrial temperature range (-40°C to +85°C). Check current product status as older revisions may be discontinued; consult official documentation for active manufacturing availability and lead-free packaging compliance.

Complex Programmable Logic Devices Selection Notes

Select this model when 64 I/Os and 2000 gates are required in an 84-pin PLCC footprint. Ensure the design utilizes 5V logic levels compatible with TTL standards. For new designs, consider the recommended successor ispLSI2064E family, which offers enhanced performance while maintaining form and function compatibility.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2000AFamily, representing an enhancement over the original ispLSI 2064 with identical timing specifications but improved manufacturing via 0.35-micron technology. It serves as a bridge between simple PLDs and larger FPGAs, offering non-volatile configuration suitable for glue logic replacement.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends using the ispLSI2064E for new designs due to its superior performance characteristics. Direct pin-to-pin replacements should verify that the target device maintains the same 84-pin PLCC package and voltage requirements.
