Complex Programmable Logic Devices Procurement Notes

Verify the ordering suffix LT128 corresponds to the standard 128-pin TQFP package. Confirm whether commercial or industrial temperature grades are required for the specific application environment. Ensure design tools support the E2CMOS non-volatile programming requirements for this device family.

Complex Programmable Logic Devices Selection Notes

Select the -250 speed grade for designs requiring up to 250 MHz clock frequencies. Consider the -135 or -100 variants if lower power consumption or reduced switching noise is prioritized over maximum speed. Verify pin compatibility with existing ispLSI 2096V footprints if migrating from previous generations.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2096VE family, which offers enhanced performance over the earlier ispLSI 2096V series. It is designed as a drop-in replacement for legacy CPLDs while providing higher density and faster speeds. The device is part of Lattice's SuperFAST portfolio aimed at replacing discrete logic solutions.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2096VE-250LT128 is functionally and pinout compatible with the ispLSI 2096V series devices. Designers upgrading from older versions should verify timing constraints due to the improved speed characteristics.
