• High I/O density with 312 available pins
• Commercial grade operating temperature range

Applications

• SDRAM controller implementation
• High-speed data handling systems
• Complex digital logic interfacing

Procurement Notes

Verify the specific suffix '60' against official datasheets to confirm timing characteristics, as variations may exist. Confirm the 492-ball BGA package type matches board layout requirements. Ensure compatibility with existing JTAG or ISP programming infrastructure. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when high pin count and moderate speed are required. The 840 macrocell capacity suits complex state machines. Consider thermal management for the BGA package. Verify that the 15 ns delay meets system clock constraints. Evaluate programming tool availability for ispLSI devices.

Part Context

This part belongs to the Lattice ispLSI family of CPLDs. These devices utilize EEPROM technology for non-volatile configuration storage. The series offers reprogrammability without erasing the entire chip, allowing partial updates. This architecture supports rapid prototyping and field upgrades.

Replacement Considerations

Direct substitutes include other members of the ispLSI8000 series with compatible pin counts. Verify logic cell equivalence and I/O voltage levels before substitution. Cross-reference package dimensions for mechanical fit. Confirm programming interface compatibility with existing debuggers.
