Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure storage conditions meet moisture sensitivity level requirements.

Selection Notes

Select this device when high pin count and moderate logic density are required. Consider the 128-TQFP package for surface-mount applications. Evaluate timing constraints against the 10 ns delay specification. Verify power supply compatibility with the 4.75V to 5.25V operating range.

Part Context

Part of the Lattice ispLSI 1000E family, designed for complex programmable logic applications. Offers a balance of performance and density for mid-range digital designs. Supports standard CMOS I/O levels and provides reliable operation in industrial environments.

Replacement Considerations

Check for compatible devices within the same ispLSI 1000E series. Verify pinout and functionality matches for direct substitution. Consider newer Lattice FPGA alternatives if higher performance or lower power is needed.
