Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-100) matches the required 100 MHz operating frequency. Confirm the LT128 suffix corresponds to the lead-free 128-pin TQFP package variant. Ensure design tools support the ispLSI 2192VE family for programming via the BSCAN interface.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 8000 PLD gates and 96 I/Os. Compare against the -225 speed grade if higher performance (225 MHz) is needed. Consider pinout compatibility with legacy ispLSI 2096V/VE designs if migrating existing hardware. Verify thermal requirements for the TQFP package under maximum load conditions.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2192VE family of SuperFAST high-density PLDs. It serves as a bridge between traditional PLDs and FPGAs, offering FPGA-like density with PLD ease of use. The device is part of Lattice's E2CMOS-based portfolio designed for low power and high reliability applications.

Complex Programmable Logic Devices Replacement Considerations

Pinout compatible with ispLSI 2096V and ispLSI 2096VE. For higher speed requirements, consider the ispLSI 2192VE-225 variant. No direct cross-model substitutes are documented; verify functional equivalence carefully when replacing.
