Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Check for moisture sensitivity handling instructions prior to assembly. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when a 512x18 synchronous FIFO is required for unidirectional data flow. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the PLCC-68 package constraints for board layout. Evaluate thermal performance within the specified commercial temperature range.

Part Context

This part belongs to the Renesas 7200 series of FIFO memories, which includes various configurations of synchronous and asynchronous devices. The 72215LB25JI8 specifically offers a 18-bit width configuration, distinguishing it from 9-bit variants in the same family. It shares architectural similarities with other members like the 72215LB25J but differs in packaging suffix.
