Procurement Notes

Verify the specific suffix LB492 to confirm the 492-ball PBGA package type and pinout compatibility with your PCB footprint. Ensure the -125 speed grade aligns with your timing requirements. Confirm that the manufacturer is Lattice Semiconductor Corporation to avoid counterfeit components. Check for any recent supply chain advisories related to this legacy CPLD series before finalizing procurement orders.

Selection Notes

Select this component when a high number of logic resources is required in a single package compared to smaller CPLDs. The 600-macrocell count suits designs needing substantial combinational or sequential logic. Consider the PBGA492 package size constraints during mechanical layout. Evaluate if the 13.5ns performance meets the system clock speeds. Compare against newer Lattice families if power consumption or advanced security features are critical priorities.

Part Context

This part belongs to the ISPLSI8600V family of SuperBIG High Density PLDs. It represents a mature technology node within Lattice's embedded programmable logic portfolio. The series is known for reliability in long-life industrial applications. It serves as a bridge between simple gate arrays and more complex FPGAs, offering deterministic timing and ease of use for standard logic implementations.

Replacement Considerations

Direct substitutes include other variants within the ISPLSI8600V family such as the ISPLSI8600V-90LB492 for different speed grades. Cross-reference pinouts carefully when considering alternative packages. Newer Lattice MachXO or CrossLink series may offer pin-compatible options but require software migration. Verify electrical specifications and I/O voltage levels before swapping components.
