Complex Programmable Logic Devices Procurement Notes

All devices in the ispLSI 1016 family, including the -90LJ variant, have been officially discontinued via Product Change Notification PCN#13-10. Verification of current product status should reference this notification. Sourcing new units is not supported by the manufacturer.

Complex Programmable Logic Devices Selection Notes

This component belongs to the legacy ispLSI 1016 series. Designers requiring field-programmable logic should evaluate modern Lattice families such as MachXO or CrossLink-NX. Selection must account for the discontinuation status and availability of alternative packages like TQFP or JLCC if pinout compatibility is required.

Complex Programmable Logic Devices Part Context

The ispLSI 1016 series represents an early generation of in-system programmable PLDs. The -90LJ suffix indicates the commercial grade with a 90 MHz speed rating in a 44-pin PLCC package. This family established non-volatile reprogrammability for complex logic applications prior to the dominance of modern FPGA architectures.

Complex Programmable Logic Devices Replacement Considerations

Public confirmed substitute part numbers are not available due to the discontinued status of the entire ispLSI 1016 family. No direct cross-model replacements are documented in the provided datasheet.
