Procurement Notes

Verify the specific suffix requirements for your design, as variants like BG8 or BGGI may differ in packaging or temperature ratings. Confirm RoHS compliance status, as some versions are non-compliant. Check current availability, as this part number may be subject to end-of-life notices or discontinuation. Ensure the selected package matches your PCB footprint specifications precisely.

Selection Notes

Select this component when a 128K x 36 configuration is required with 8 ns access speed. Consider the 119-pin PBGA package constraints during layout. Evaluate power consumption against the 3.3V core supply specification. Compare against other members of the 71V3557 family if different pinouts or temperatures are needed.

Part Context

This part belongs to the IDT 71V3557 series of synchronous ZBT SRAMs. The series offers various access times and packages to support diverse embedded memory needs. Renesas acquired the IDT product line, maintaining these specifications under the Renesas brand.
