Procurement Notes

Verify current availability status as the component may be subject to end-of-life notices or limited distribution channels. Confirm package authenticity and check for RoHS compliance requirements specific to your region. Ensure that the supplier provides valid traceability documentation for this specific part number before finalizing any acquisition plans.

Selection Notes

Select this component when a 36-bit wide data bus is required for system architecture compatibility. Consider the 119-pin BGA footprint for PCB layout constraints and thermal management needs. Evaluate the 8.5 ns access speed against system timing requirements to ensure synchronization with the host processor's clock domain without introducing latency penalties.

Part Context

This SRAM belongs to the 71V3577 family, designed for applications needing wide data paths and synchronous operation. It serves as a high-density volatile memory solution within Renesas' portfolio, bridging the gap between standard SRAMs and specialized cache memories. The technology emphasizes low power consumption while maintaining high throughput for complex data handling tasks.

Replacement Considerations

Check for direct substitutes such as the IDT71V3577 series variants. Verify pinout compatibility and electrical specifications before substituting. Consult official manufacturer change notices for any updated packaging or substrate modifications.
