Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify current stock availability through authorized distributors before finalizing design implementations. Due to the end-of-life status, long-term supply continuity cannot be guaranteed. Evaluate alternative sourcing options or transition plans immediately to mitigate production risks associated with this specific part number.

Selection Notes

Select this part when a 36-bit wide synchronous SRAM is required for ECC-based memory designs. Ensure the system architecture supports 117 MHz clock speeds and 3.3V I/O levels. The 100-TQFP package requires appropriate PCB footprint verification. Consider the 6.5 ns access time against system latency requirements. Confirm that the industrial temperature range meets environmental specifications for the target deployment scenario.

Part Context

The 71V3577S series represents Renesas' high-density synchronous SRAM family designed for demanding data processing tasks. This specific model utilizes advanced CMOS technology to deliver low power consumption alongside high-speed performance. It serves as a critical volatile memory solution in applications where rapid random access and wide data buses are essential for maintaining system throughput and data integrity.

Replacement Considerations

The 71V3577S85PFGI8 is listed as a similar substitute offering comparable functionality with an 8.5 ns access time. Verify pinout compatibility and electrical characteristics before substitution. Other family members may require design adjustments due to differing speed grades or package types.
