Complex Programmable Logic Devices Procurement Notes

All devices in the ispLSI 1032 family are officially discontinued by Lattice Semiconductor. Product Change Notifications PCN#13-10 and PCN#05A-10 confirm this status. Verification of current availability should rely on distributor stock lists rather than manufacturer production schedules.

Complex Programmable Logic Devices Selection Notes

Select the -80 speed grade for an 80 MHz maximum operating frequency and 15 ns propagation delay. Ensure the design fits within the 64 I/O limit and 192 register capacity. Verify that the application environment remains within the commercial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 1032 series, which represents early high-density CPLDs from Lattice. It utilizes non-volatile E2CMOS technology, allowing for electrical erasure and reprogramming without removal from the circuit board.

Complex Programmable Logic Devices Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Discontinued status requires evaluation of modern Lattice ispMACH or CrossLink families for functional equivalents.
