Memory IC Procurement Notes

Verify the specific suffix designation against official manufacturer documentation, as variations exist within the product family. Confirm RoHS compliance status directly with the supplier, as regulatory adherence varies by manufacturing batch and region. Ensure that the procurement channel provides valid traceability records for this discontinued or end-of-life component type.

Memory IC Selection Notes

Select this component when a 36-bit wide data path is required for system integration. The 100 MHz speed grade offers a balance between performance and power consumption for general-purpose synchronous applications. Verify that the PCB layout accommodates the 119-pin BGA footprint and thermal requirements associated with this package style.

Memory IC Part Context

This part belongs to the 71V2546 series of synchronous SRAMs manufactured by Renesas Electronics. The series is designed for applications demanding high bandwidth and low latency. The '100' suffix indicates the specific speed bin, while 'BG' denotes the ball grid array packaging configuration used for surface-mount assembly.

Memory IC Replacement Considerations

Consult official substitution guides for compatible parts such as the 71V2546S133BG or 71V2546S150BG8, ensuring pin compatibility and electrical specifications match the design requirements.
