Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm package integrity and pin alignment prior to integration. Check for moisture sensitivity level compliance during storage handling. Ensure voltage supply stability within the specified 4.5V to 5.5V range to prevent operational failure. Review datasheet for any specific end-of-life replacement recommendations from Renesas.

Selection Notes

Select this component for applications requiring reliable synchronous data buffering between asynchronous or synchronous logic blocks. The 9-bit width suits standard data bus configurations. Consider the 32-PLCC package constraints for PCB layout. Evaluate thermal dissipation requirements given the 80mA maximum current draw. Verify that the 40MHz speed meets system timing requirements.

Part Context

This device is part of the Renesas 7200 series of FIFO memories, designed for general-purpose data buffering. It utilizes CMOS technology to provide high-speed operation with low power consumption. The 72215 variant specifically offers a 512x9 organization, making it suitable for moderate depth buffering needs in embedded systems and communication interfaces.

Replacement Considerations

Check for direct pin-compatible replacements within the 7200 series. Verify if upgraded variants with RoHS compliance are available. Ensure functional equivalence regarding access time and operating voltage before substitution.
