Complex Programmable Logic Devices Procurement Notes

This component is officially discontinued per Product Change Notification #09-10. Verify availability through authorized distributors for surplus stock only. Ensure the 68-pin PLCC package matches the target footprint. Confirm that the design can accommodate the transition to modern replacement devices if new production is required.

Complex Programmable Logic Devices Selection Notes

Select this part for legacy designs requiring 5V operation and in-system programmability. The -60 suffix indicates a 60 MHz performance tier. Compare against the -80 or -90 variants if higher speeds are needed. Note that the device requires a 5V supply and TTL-compatible input/output levels.

Complex Programmable Logic Devices Part Context

The ispLSI 1024 belongs to the first generation of in-system programmable high-density PLDs from Lattice. It utilizes a unique Global Routing Pool architecture distinct from traditional PLDs. This specific model represents the commercial grade 60 MHz variant in a plastic leaded chip carrier package.
