Complex Programmable Logic Devices Procurement Notes

Verify component authenticity against official Lattice Semiconductor documentation. Confirm that the specific ordering suffix corresponds to the commercial grade 128-pin TQFP package. Ensure handling procedures account for moisture sensitivity as indicated in manufacturer guidelines.

Complex Programmable Logic Devices Selection Notes

Select this variant for designs requiring 225 MHz operation speed. The LT128 suffix denotes the lead-free 128-pin TQFP package. Consider the -180 variant if lower power consumption is prioritized over maximum speed, or the -135 variant for cost-sensitive applications with relaxed timing requirements.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2192VE family of SuperFAST high-density PLDs. It serves as a direct pin-compatible upgrade to the ispLSI 2096 series, offering increased density with 8000 gates and 192 registers while maintaining similar form factors and programming interfaces.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2192VE-180LT128 and ispLSI 2192VE-135LT128 are pin-compatible alternatives within the same family. Substitution requires verification that the reduced maximum operating frequencies meet the design's timing constraints.
