Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lead-free status and industrial temperature range compliance (-40°C to +85°C). Check for moisture sensitivity level (MSL) handling requirements prior to assembly. Ensure programming tools support the specific ispLSI 2000A family for reliable configuration.

Complex Programmable Logic Devices Selection Notes

Select this model when 2000 PLD gates and 64 I/Os are required in a 100-pin TQFP package. Choose the -80 speed grade for 81 MHz operation and 15 ns propagation delay. Opt for the 'I' suffix for industrial temperature range applications. Consider the LT100N variant if lead-free packaging is mandated by environmental regulations.

Complex Programmable Logic Devices Part Context

The ISPLSI2064A series is part of Lattice's ispLSI 2000AFamily, offering form-and-function compatibility with the original ispLSI 2064 but built on improved 0.35-micron technology. It serves as a bridge between traditional PLDs and FPGAs, providing flexibility with deterministic timing. The device is designed for applications needing reconfigurable logic with non-volatile storage capabilities.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends using the ispLSI 2064E for new designs. Direct pin-compatible replacements may include other members of the ispLSI 2000A family, such as the ISPLSI2064A-100LT100I for higher speed or ISPLSI2064A-125LT100I for even faster performance, provided timing constraints allow.
