Procurement Notes

Verify current availability status as this specific part number may be discontinued or subject to production changes. Confirm the exact package marking and suffix requirements against official manufacturer documentation before finalizing orders. Ensure compliance with moisture sensitivity level handling procedures during assembly processes.

Selection Notes

Select this component when a 36-bit wide synchronous SRAM interface is required for system integration. Consider the 119-pin BGA footprint constraints and thermal management needs for surface mount applications. Evaluate the 7.5 nanosecond access speed against system timing requirements to ensure compatibility with target processor buses.

Part Context

This device belongs to the 71V3557 series of synchronous SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family but differs in specific pin configurations and package options.
